Enter your baby's date of birth and get the full South African (EPI-SA) immunisation schedule turned into real calendar dates. See exactly when each clinic visit falls, which vaccines are given that day, and which one is coming up next. Tick off each dose as it is done, and print or save the list for the clinic card. You can also add the upcoming visits to your phone calendar, with an offline reminder set for the morning before each one. Switch on the commonly recommended private extras, such as chickenpox, hepatitis A, flu and the meningococcal vaccines. And if your child has fallen behind, a second toggle checks which doses may be overdue for their age.

Search for your condition, or browse common conditions by body system, and find out whether it is a Prescribed Minimum Benefit or one of the 26 Chronic Disease List conditions, and exactly what your medical scheme must pay for by law. Every scheme has to cover these in full, on every plan, paid from the risk pool and not your savings. There is also a checklist to spot when a scheme is short-changing you, and the steps to complain to the Council for Medical Schemes.

Belong to a medical aid? SARS gives you money back, and there are two credits, not one. This tool works out both. The first, the medical scheme fees tax credit, is a fixed amount for every person on your scheme, whatever plan you are on, and it shows straight away. The second, the additional medical expenses credit, is the one most people never claim, for years when contributions ran high or you paid big bills out of your own pocket, and it is far more generous from age 65 or where there is a disability in the family. Pick your tax year, 2026 or 2027, add your details, and it gives you the figures, then warns you honestly when a credit is bigger than the tax you actually owe, since a credit is never paid out as a refund on its own.

Work out your due date and see how far along you are, from the first day of your last period, a due date you already have, or a dating scan, then turn it into your actual South African antenatal clinic visits on real dates, using the public sector BANC+ schedule. It lays out all eight contacts, the booking visit and the follow ups at 20, 26, 30, 34, 36, 38 and 40 weeks, with a short plain note on what happens at each, the booking bloods, the repeat tests, the check that baby is head down. Tick each visit off, add them to your phone calendar with a reminder the day before, and print the plan for your clinic card. There is a clear danger-signs list too, the things that mean you should go to the clinic the same day. When baby arrives, the immunisation schedule tool takes over.

See where your child sits on the growth charts, using the same World Health Organization standards behind South Africa's Road to Health book. Enter your child's sex, date of birth and what you measured, weight, length or height, or head circumference, and it gives you the percentile in plain language, for any age from birth to five years. It shows where they sit between the 3rd and 97th percentile lines, gives the median for their age to compare against, and gently flags when a reading is far enough outside the usual range to be worth showing your clinic. Just as useful, it explains what the number actually means, since a low or high percentile is so often misread, and reminds you that the line your child follows over time matters far more than any single reading.

South Africa is switching to the AARTO demerit points system, where every traffic offence adds points to your licence and enough points get it suspended. This tool lets you build a scenario from common offences, a speeding band, a skipped robot, a missing licence card, and watch a live meter add up the points against the 15-point limit. It tells you whether you are still safe or heading for a suspension, and how many months that suspension would last, because the rule is three months for every point over the limit. It also explains how points are added, how a clean record clears them at one point every three months, and when the system is expected to start. It is an educational guide, not a lookup of your real record, and nothing you enter leaves your browser.

What should your car licence disc renewal actually cost? There is no single national fee, each province sets its own and it rises with how heavy your car is, so the same vehicle costs a different amount to licence from one province to the next. Pick your province, type in your tare weight, the empty weight printed on your disc and RC1, and this free tool gives you the annual fee plus the RTMC transaction fee. Add your expiry date and it also works out what you owe if the disc has already lapsed, with the 21 day grace period, the arrears and the 10 percent per month penalty all laid out, and it can drop a renewal reminder into your calendar so you are never caught late again. The late figure is a close estimate to confirm at the counter, and nothing you enter leaves your browser.

Selling a car privately gets you a better price than a trade-in, but it hands you all the paperwork a dealer would normally handle. This tool asks about your outstanding finance and your roadworthy status, then builds a personalised checklist covering the settlement letter, the roadworthy certificate, and the Notification of Change of Ownership, the yellow form, with its 21 day deadline. A second tab generates an actual voetstoots sale agreement, fill in both parties' details, the vehicle's VIN and engine number, the price and any known defects, and it produces a printable document with a proper voetstoots clause, including the two limits people usually get wrong. There is also a blunt warning about the fake proof-of-payment scam that catches out private sellers. Nothing you type is sent anywhere, including the ID numbers.

Find a campsite close enough for a real weekend in the bush. Tell it whether you are leaving from Joburg or Pretoria and how far you want to drive, then filter by the kind of place you fancy, a Big 5 reserve, a mountain with rock pools, a river for rafting, a dam for watersports, or a hot springs family resort, plus whether you need a power point or somewhere that suits young kids. Every site is one I checked, with honest notes on what it is really like, the drive time from both cities and a link straight to the official booking page.

Want the most time off for the fewest leave days? South Africa has a handful of public holidays that sit just one or two working days from a weekend, and bridging them turns an ordinary weekend into a long break. This planner ranks the smartest leave plays for 2026 and 2027, shows exactly which days to book and how many days off you end up with, and lets you send each plan straight to your calendar. It handles the tricky rules for you, moving Sunday holidays to the Monday and flagging the Saturday ones you simply lose, and it even includes the likely 4 November 2026 election day with an honest reminder to confirm it first. New Optimise my year mode goes further, taking your whole leave allowance for a year and working out the exact dates to book, whether you want one long holiday, as many long weekends as possible, or a balanced mix, and it plans around any blackout dates you cannot take off.

Thinking of moving somewhere better in South Africa without leaving the country? This finder ranks real semigration towns against what actually matters to you, a well run municipality, affordable housing, closeness to a big-city job market, good private healthcare, reliable water and a nearby airport, then shows the evidence behind each one. Governance uses the latest Auditor-General audit outcome for each town's municipality, the distances to the nearest city, airport and private hospital are worked out for you, and for crime it links you straight to the live police station data rather than inventing a score. Set your priorities and it builds your shortlist, with an honest note on the catch for every town.

Flying out of OR Tambo and not sure whether to take the Gautrain, to drive and pay for long stay parking, or to grab an Uber? It is harder to work out than it sounds, because the train charges every passenger a separate fare while driving and parking is one price for the whole car, and an Uber is its own thing again, so the cheaper option flips with how many of you are going and how long you will be away. This calculator does the full sum all three ways, the petrol there and back plus the real ACSA parking tariff, every train fare plus the cost of getting to the station, and an Uber both ways, then tells you which wins, by how much, and the trip length where it would flip. It uses the official Gautrain fares and OR Tambo parking rates, flags the quirk that makes four days of parking cheaper than three, and is honest about the things money does not show, like the train not running late at night.

How many cattle, sheep or goats can your farm actually carry without wearing the veld down? This calculator starts from the Department of Agriculture's own hectares per Large Stock Unit figures, driven by your veld type, grassveld, bushveld or Karoo, rather than a single national average that is wrong for most of the country. It then lets you adjust honestly for how your veld condition and the season are actually looking, because the official figures assume veld in good condition and a below average rainfall year needs a lower number. Mixed herds of cattle, sheep and goats are converted onto one Large Stock Unit scale, and the result keeps a recommended stocking figure, with a buffer for a dry year, separate from the maximum ceiling you should never cross. It is a planning estimate, not a substitute for your district's legally gazetted grazing capacity figure.

Most borehole tools online only price the drilling and the pump, then stop, leaving out the electricity bill that ends up costing far more over the years. This calculator works out what your pump actually costs to run, in rands per month and rands per 1 000 litres, on Eskom's Ruraflex or Landrate tariffs. Ruraflex charges up to four times more at peak times than off-peak, so the tool shows exactly what you would save by shifting pumping to off-peak hours and whether your tank is big enough to make that switch practical. Also covers cost to irrigate a given area, and a diesel generator comparison for backup power.

How many bags do you need, and are you actually getting value for money? This calculator works in elemental N, P and K, the South African way, not the oxide form (P₂O₅, K₂O) that international calculators use and that quietly leads you to over-apply phosphorus and potassium. Put in your product, area, rate and bag size and it gives you the bags to buy, the total kilograms and the cost, plus what that feeds into the soil. The number that earns its keep is cost per kilogram of nutrient, which is how you tell whether urea or LAN is really the cheaper nitrogen once you look past the bag price. A second tab checks a multi-product plan against your soil test target, met, short or over on each nutrient. It turns a rate you already have into bags and cost, it does not invent a recommendation, that still needs a soil test.

Most lime calculators are built for an American or British buffer pH test that a South African soil lab report never gives you. Here agronomists work in percentage acid saturation instead, and this tool uses the Cedara method, well documented and widely used in KwaZulu-Natal, to turn your soil test figures into a lime requirement, or you can enter a figure you already have and skip the estimate. A 2017 Stellenbosch University study found South Africa's competing lime methods can disagree by two to ten times on the same soil, so an accredited lab's own figure always wins over this calculator's estimate. The part that actually decides which lime to buy is cost per effective tonne, price adjusted for CCE% and delivery, since two limes at the same price rarely deliver the same neutralising value and cartage often costs as much as the lime itself. Also gives a dolomitic versus calcitic recommendation from your soil magnesium.

Length times width times depth, the sum most people reach for, overstates what a real dam holds, because actual farm dams have sloped earth banks, not vertical box walls. This calculator uses the same shape-correction formulas Australian agricultural authorities publish and use themselves, checked here against their own worked examples, across three shape modes, a simple dam, a valley or gully dam, or one you've measured with depth soundings yourself. Volume is only half the story, though. South Africa's open-water evaporation is often severe, sometimes the biggest loss on a dam, so the tool works that out from your dam's real surface area and a regional figure, adds whatever you're drawing for stock, irrigation or the house, and tells you honestly how many days that water actually lasts. Also flags dams large enough to need Department of Water and Sanitation registration.

Knowing your dam's volume only tells you the ceiling, not whether it actually fills. This calculator runs your catchment area, soil type and dam depth against ten real years of daily rainfall for your nearest of 68 South African towns, the same decade this site's Rainwater Tank Calculator uses, to show how reliably your dam meets your demand over a normal year rather than a single annual rainfall figure. Dam depth matters more than it looks: a shallow, wide dam loses proportionally more to evaporation than a deep one holding the same volume, since evaporation acts on surface area, not litres stored. Runoff coefficients come from a published soil-runoff table applied against your own town's rainfall, and since dam excavation cost varies too much by site to model honestly, this tool stays descriptive, reliability and nothing invented, not a rand figure.

Split one block into a grid of camps and multiply the number of camps by one perimeter, and you'll overorder wire and posts by 25% or more, because the fence between two neighbouring camps is shared, it only gets built once. This calculator works out that real shared length first, whether you're subdividing a block, fencing standalone camps, or already know your total run, then applies South Africa's own fencing standards for post spacing, dropper counts and strand numbers by fence type, cattle, sheep, mixed stock, jackal-proof or a proper game fence by species group. Strainer and corner posts, which cost several times what a standard post does, are split out from the cheaper standards in between, gates are worked in too, and everything lands in a materials and cost breakdown you can check a supplier's quote against.

Buy a weaner and feed it out to slaughter weight, and the number that actually decides whether it was worth doing is the break-even sale price, not the sale price on its own. This calculator adds up feed, yard or feeding fees, health and processing, transport, finance on the capital tied up, and the red meat levy, spreads the sunk cost of any animal lost to mortality over the ones that make it to the scale, then divides by the weight you'll actually get paid for after shrinkage and commission. Feed conversion, average daily gain, mortality and days on feed default to real South African feedlot benchmarks, SA Grain and SASAS, not guesses, while purchase price, feed cost and sale price stay yours to enter, since those move too often for any calculator to guess safely.

Most planting calendars found online are written for the Northern Hemisphere, so July reads as midsummer instead of the Highveld's coldest month. This tool uses South African regional planting charts instead, picking between four genuinely different patterns, the summer-rainfall Highveld, the winter-rainfall Western Cape, the semi-arid Northern Cape, and the frost-free subtropical coast and lowveld, based on your province and, for the handful that genuinely span more than one climate, a quick tap to say which part you're in. Pick a month and see what vegetables, herbs and fruit to plant now, each with an expected harvest month, sun and water needs, and a difficulty rating. Fruit trees show their typical bearing season and how many years that usually takes to reach, not a fake harvest date the year you plant them.

Length times width times depth gets you a volume, but that leaves you doing the litres-to-bags maths yourself, and most calculators stop there anyway. This one converts your raised bed's dimensions straight into litres and cubic metres, splits the result into topsoil and compost using a real South African mix, 70% topsoil to 30% compost for a new bed is what one Cape Town composting supplier sells premixed for exactly this job, then rounds up to whole bags for whatever size your garden centre stocks. Building a deep bed? An optional base-fill layer lets you part-fill the bottom with logs, straw or rubble and only pay for growing mix in the layer roots actually reach. It then prices both buying bagged and ordering bulk by the cubic metre from your own numbers, since bagged soil carries a real retail markup that bulk usually beats once you're past a bed or two.

Every other rainwater calculator multiplies your roof area by one annual rainfall figure, which tells you what lands on the roof but not what a tank will actually deliver, because a tank is limited by timing rather than totals. This one simulates a tank day by day against ten years of real daily rainfall for your town, then tells you the smallest size that covers the share of your watering you asked for. The gap that opens up is bigger than most people expect: the same roof, tank and garden covers about 84% of the watering in Johannesburg and about 62% in Cape Town, because Highveld rain arrives in summer when a garden is thirsty and Cape rain arrives in winter when it is not. In a dry town it will tell you honestly that no tank is big enough and give you the ceiling your roof can reach. It also prices the saving against your real stepped municipal tariff, where the water you stop buying comes off your top block, not off an average, which moves the effective rate in Johannesburg from about R27 to about R74 a kilolitre depending on how much you already use.

On 1 April 2026 the eligible share for the on-land diesel rebate, officially the diesel refund, farming, forestry and mining, jumped from 80% to 100%, and SARS's own method for a VAT period that straddles that date is not simple arithmetic, the litres either side have to be scaled onto the same footing before they're added together. This calculator does that adjustment exactly as SARS's own policy, SE-DSL-02, sets it out, and includes a one-click button that loads SARS's own worked example and reproduces its stated result, R52,751, to the rand, so you can check the tool against the source before trusting it with your own claim. A simple tab covers a period that sits entirely on one side of a rate change, and a built-in rate history table tracks every Government Gazette change through 2026.

Sole proprietor, Turnover Tax, or a registered company, which one actually pays you the most? A registered company's tax rate looks appealing next to personal income tax, but profit sitting inside a company is not yet your money, getting it out as a salary or dividend is taxed again. This calculator takes your turnover and expenses for 2026/27 and searches every salary-to-dividend split to find the one that puts the most real cash in your pocket, not just the lowest company tax bill, alongside the CIPC registration fee and when VAT becomes compulsory.

A job advert says R15,000 a month, so that's what hiring them costs, right? Not quite. This calculator adds employer UIF, the Skills Development Levy, a Compensation Fund (COIDA) assessment for your industry, plus whatever pension, medical aid or 13th cheque you choose to offer, on top of a basic salary for 2026/27. Then it applies the Employment Tax Incentive, a PAYE saving for hiring someone 18 to 29 that most cost-to-hire calculators leave out entirely, and shows the true cost per productive day once leave and public holidays are accounted for.

Every provisional tax calculator splits your estimate in half for the August and February IRP6 payments. This one also checks whether the estimate you're about to declare would protect you from SARS's 20% underestimation penalty, either through your "basic amount" safe harbour or the 90%/80%-of-actual test, and shows the exact rand exposure if it wouldn't. Compare paying safe against paying your honest estimate, see the R1 million cliff where the basic amount stops helping, and export the deadlines to your calendar.

Most compliance calendars show every CIPC, SARS and UIF deadline to everyone. This one asks whether you're a sole proprietor, a trust or a company, VAT registered, have employees, and builds a personalised list of only the deadlines that apply, each computed from the actual rule (including South Africa's public holidays), not copied from last year's article. Covers CIPC's Annual Return and Beneficial Ownership Declaration, ITR14 or ITR12T, provisional tax, VAT, EMP201/EMP501, COIDA and B-BBEE affidavit renewal, export any deadline, or the whole list, straight to your calendar.

Calling someone a contractor in the contract settles nothing, and four separate tests can disagree about it. This checker runs all of them over the same facts: SARS's two conclusive statutory tests, the personal service provider rules that catch anyone invoicing through their own company, SARS's own 22-indicator dominant impression grid weighted the way SARS weights it, and the Labour Relations Act presumption that decides whether the CCMA is open to them. It shows where each one lands, explains the IRP5 3601 versus 3616 difference that decides whether the worker keeps their deductions, and prices what the unwithheld PAYE, the 10% penalty and the unpaid UIF would cost an employer who got it wrong.

Cash flow, not profit, is the thing that actually breaks small businesses. This calculator turns your debtor days, stock days and supplier days into an actual rand figure, priced correctly (debtors at sale price, stock and payables at cost, not one blended rate), and shows what a single day faster payment, a single day less stock, or a single day longer to pay suppliers is really worth. It also models the "growing broke" trap, how a growing, profitable business can still need extra cash tied up before the growth pays for itself, and gives an honest illustrative facility cost against South Africa's own prime lending rate.

Below R2.3 million a year, registering for VAT is a business decision, not a legal duty, and every other free tool only tells you whether you are allowed to. This one works out whether you should. It models the VAT you would actually get back on costs (15/115 of what you spend, not 15%, and nothing at all on salaries, interest, fuel or rates), and the question that usually settles it: whether your customers are VAT-registered businesses who claim the 15% straight back, or consumers who feel every rand of it. It works out your break-even pass-through, the cash flow effect of owing SARS before your customers pay you, and whether the payments basis is even open to you, which for a company it never is. It also runs backwards for anyone freed to deregister by the 2026 threshold increase, including the exit VAT on assets you still hold.

Other leave calculators answer the employee's question, how many days do I have left. This one answers the employer's, which needs a rand figure and a compliance check. It works out the annual leave balance in days and in rand, the number that belongs in your books as a leave provision, and it separates that from what you would actually pay out, because section 40(c) floors the incomplete cycle at one day per 17 days worked whatever your accrual method produced. It handles the 36 month sick leave cycle including the one day per 26 days worked rule in an employee's first six months, the section 22(4) reduction that the Act makes optional rather than automatic, the two gates on family responsibility leave that quietly disqualify anyone on a three day week, and the section 37 notice ladder. Overtime, Sunday and public holiday pay are calculated at the statutory rates and correctly switched off above the R269,600.90 earnings threshold, which leave entitlements never are. Parental leave reflects the Constitutional Court's Van Wyk order of 3 October 2025, not the old four months for the mother and ten days for the father still published almost everywhere else.

Most paint calculators ask you to type in a number of coats and hand back litres. This one works out how many coats you actually need instead, starting from two standard coats and adding a coat for a big colour change, light to dark or dark to light, or for exterior work in a coastal or high-humidity area, and shows you exactly why. It also knows South African paint is sold in 1, 5 and 20 litre tins, not the 10 litre size some generic calculators assume, and works out the cheapest combination of those three sizes for your exact litre count. Coverage rates come from published South African paint technical data sheets, lower for new bare plaster (which also needs a primer coat) and far lower again for textured exterior coatings, rather than one generic number for every job. Add a ceiling, priced separately from wall area, or any extra wall that doesn't fit a simple rectangle.

Most tile calculators, including the ones tile retailers run themselves, hand back a bare tile count from a flat waste percentage and stop there. This one adds up every room you're tiling, subtracts anything you don't tile under like a built-in bath or a kitchen island, and applies the right waste percentage for your actual layout, 10% for a straight grid, 15% for diagonal, 20% for herringbone. It then works out adhesive and grout the way a tiler actually buys them, coverage rates from published South African technical data sheets for the trowel notch size your tile calls for, and grout rounded up to South Africa's real 20kg, 5kg and 2kg bag sizes. Alongside your own DIY materials total, it shows what a professional tiler would likely charge for the same job using 2026 South African market rates.

Most concrete calculators either use a generic international 1:2:4 ratio or just split your target volume across the raw ratio numbers, both of which under-order, since loose, dry materials compact once mixed and don't add up to the volume of concrete they make. This one uses PPC's own published South African figures for cement bags, sand and stone per cubic metre of finished concrete, by strength grade, foundation, slab or structural, for slabs, strip footings and fence post holes. On the mortar side it works out bricks or blocks per square metre from AfriSam's published masonry reference, then the cement and sand for a Class II mortar mix. Results come out in bags, wheelbarrows and cubic metres, and for concrete it shows whether bagged pre-mix, mixing your own, or a ready-mix truck works out cheaper for your exact volume.

Most laminate/vinyl flooring calculators hand back a bare pack count from a flat waste percentage and stop there. This one adds up every room you're flooring, applies the right waste percentage for your actual layout, 10% for a straight plank run, 15% for diagonal, 20% for herringbone, and rounds up to whole packs. It also works out underlay matched to your subfloor, a moisture-barrier combination underlay for laminate over concrete, plain foam over timber, or none at all for SPC click vinyl which usually ships with its own attached backing, skirting boards from your rooms' real perimeter rounded up to whole lengths, and transition strips for every doorway plus any internal expansion joint a long continuous run needs. Alongside your own DIY materials total, it shows what a professional installer would likely charge, laminate and vinyl priced separately, using 2026 South African market rates.

Most paving calculators do one thing, divide your area by the size of one paver and stop there. This one prices the whole layered job, sourced directly from Bosun's own paving installation guide and the Concrete Manufacturers Association's paving specification. Switch between Patio and Driveway and the defaults change with it, a driveway locks in a compacted G5 crusher-run sub-base (essential once vehicles are involved), thicker 60mm pavers and a herringbone pattern that resists sideways spread under load, while a patio can use lighter 50mm pavers and, honestly, get away without a proper sub-base if it's pedestrian only. It adds up pavers, bedding sand, jointing sand (a separate material from bedding sand, swept dry into the joints), sub-base, and the concrete needed to bed and haunch a proper edge restraint, the part that stops paving creeping apart at the borders. A labour estimate shows what a professional would likely add on top.

Most decking calculators just give you a board count from a flat area. That's the easy part, the joists, bearers, posts and footings underneath are what people forget, and usually the bigger part of the cost anyway. This one asks for your deck's length, width and which way the boards run, since joists always cross the boards at right angles and bearers run under the joists parallel to the boards, resting on the posts, and works out a proper directional grid rather than an area sum. Joist spacing is set automatically from your board thickness and material (SANS 1008 guidance, tighter again for composite), screws or hidden clips are counted at every real board-joist crossing, and an attached deck with a ledger board correctly drops one whole bearer line and its posts. Handles timber (treated pine or balau hardwood) and composite, and every post's footing links straight through to the Concrete & Mortar Calculator, pre-filled with the exact count and a sensible footing size.

Every electric fence pricing page in South Africa runs the same lookup table, pick your strand count, read off a per-metre rate, and none of them show you what that rate actually buys. This one builds the real bottom-up shopping list instead, wire, brackets or posts, insulators, tensioners, earth spikes and warning signs, sized to actual SANS 10222-3 spacing rules, brackets at a maximum of 3m apart, earth spikes every 30m, signs every 10m in urban areas. The energiser is sized properly too, off your total live wire length using Nemtek's own published specifications, not a flat rule of thumb, and it flags if a big urban perimeter would need more than the legal 8-joule single-energiser cap. It then compares your fence materials total to a typical professionally installed price for the same spec, so the gap between the two numbers is explained, plus a compliance checklist covering the Certificate of Compliance, earthing, signage and the barrier-fence rule for a low freestanding fence.

Every other ceiling calculator divides your floor area by the area of one board, which is tidy and short every single time, because a ceiling is not one big surface, it is a set of separate rooms and each one needs its own part-width last row and its own cut end board. Three 3m x 3m bedrooms need 9 boards, not the 8 the shortcut promises. This one lays every room out individually, the way the boards actually go up, then does the part the others skip entirely, the structure underneath: brandering at Gyproc's specified 400mm centres running at right angles to the boards, with an extra pair wherever two boards meet end to end. Timber, cornice and joint strip are bought in fixed lengths and cut up, so it solves that as a real cutting list rather than dividing metres by stock length, and picks the stock length that wastes least per room width. Covers 6.4mm gypsum with M-strip, 9mm taped and skimmed and 4mm Nutec for bathrooms and patios, plus cornice, adhesive, screws, nails, trapdoors and optional insulation, priced at current South African retail and compared honestly against a supply and install quote.
