Vehicle Total Cost Calculator

A R350,000 sedan looks like a R350,000 decision. It isn’t. Over a typical five-year ownership cycle that same car will cost R450,000 to R600,000 in addition to the purchase price — fuel, insurance, maintenance, finance interest, and depreciation against eventual resale. The total cost of ownership (TCO) is the only number that lets you compare cars on the same footing.

The Automobile Association of South Africa publishes AA Rates per km annually — a compact way to express “everything it costs to run this car”. For 2026, the AA Rates run from approximately R4.62/km for small entry-level vehicles to R6.42/km for premium SUVs. Multiply by your annual distance and you have a defensible all-in number.

A new car loses 10-20% of its value the moment you drive it off the dealership floor — paying VAT and dealer markup that you can’t recover at resale. Over five years, total depreciation typically reaches 50-60% of the original purchase price:

The financial implication is stark: buying a 3-year-old version of the same car you wanted typically saves 40-45% of the purchase price while losing only 20-30% of useful life and warranty cover. The 1-3 year window is the sweetest spot in the SA used market for high-value cars; older than that, you start paying for maintenance you didn’t need to.

Comprehensive cover in South Africa typically costs 1-3% of insured value annually, paid in monthly instalments. The variation is driven by:

• Driver age and history. Under-25 drivers, regardless of how careful, can pay double the premium of a 35-year-old with the same car.
• Postal code. Joburg and Pretoria carry the highest premiums (high theft and hijacking incidence). Coastal cities and small towns pay 30-50% less for the same car.
• Excess level. A higher voluntary excess (R5,000 → R10,000) cuts the monthly premium by 10-20%. Worth it if you have an emergency fund that can absorb the higher excess.
• Tracking devices. A Cartrack/Tracker subscription is R150-R250/month but typically cuts insurance by R200-R400/month, plus drastically improves recovery odds on theft.

The biggest single saving is comparing quotes annually. King Price, OUTsurance, MiWay, Naked, Pineapple, and Hollard all quote on the same risk profile and the spread is routinely 30-50%. Loyalty is expensive in SA insurance.

Three different things often confused at signing:

• Service plan — covers scheduled servicing items (oil, filters, spark plugs, brake fluid, etc.) for a defined period or distance. Usually included on new sales for 3-5 years / 60,000-100,000 km.
• Maintenance plan — broader: covers wear-and-tear items (brakes, clutches, batteries, sometimes tyres). 3-7 year term. Genuinely valuable on out-of-warranty cars but expensive to buy as an aftermarket extension.
• Mechanical warranty — covers unexpected mechanical failure (engine, gearbox). Useful on used purchases or after the OEM warranty expires; the catch is that what counts as “wear-and-tear” vs “mechanical failure” can be disputed.

A car without any of the above will cost R3,000-R5,000/year minimum on routine servicing, plus R8,000-R15,000 every 50,000-60,000 km on tyres, plus unpredictable repair costs. Budget R1,500/month for a 5-year-old mid-range car and you’ll usually be in the right neighbourhood.

The R420k car cost R1.15m to operate over five years — about R19,000/month fully loaded. Anything resembling Uber-only living above ~1,500 km/month is worth comparing against this number, not the bond payment alone.

The popular rule of thumb is “buy 2-3 years old”. The maths supports it for most middle-segment cars: you skip the steepest depreciation cliff and inherit a car that’s usually still under OEM warranty with an established maintenance history.

Where the rule breaks down:

• Bottom-end new cars (Suzuki S-Presso, Renault Kwid, Kia Picanto). Depreciation is shallower because they’re cheap to start. A new one with a 5-year service plan is often genuinely cheaper TCO than a 3-year-old equivalent with a worn service plan.
• EVs. Battery uncertainty creates wider used-price variance. A new EV with full warranty often makes more sense than a 3-year-old one of uncertain provenance.
• Premium German. Out-of-warranty Audis, BMWs, and Mercedes can cost R20-40k per year in maintenance. The cheap purchase price is bait; running costs make total ownership higher than buying new.

A typical EV uses ~17-22 kWh per 100km. At a residential Eskom rate of ~R3.20/kWh, fuel cost is R55-70 per 100km — roughly one third of the equivalent petrol vehicle. Insurance costs are similar; maintenance is lower (no engine oil, no spark plugs, much less brake wear). Depreciation in years 1-3 is steeper than ICE; from year 3 onwards it’s comparable.

For households doing >15,000 km/year with home charging, lifetime EV TCO is typically R30,000-R80,000 cheaper over five years than the ICE equivalent — even after the higher purchase price. The break-even depends heavily on annual mileage; under 8,000 km/year ICE still wins.

Enter your purchase price, annual distance, fuel consumption, insurance cost, and finance details. The calculator returns annual and 5-year totals across all ownership cost components, plus a per-km figure you can sanity-check against the AA published rate.

Two flags worth watching: (1) if your finance interest is more than 25% of purchase price over the term, you’re overpaying for the car or the deal, and (2) if your insurance is more than 4% of vehicle value annually, get fresh quotes — you’re almost certainly being overcharged.
