Vehicle Finance Calculator
Work out your monthly SA car finance instalment with deposit, trade-in and balloon. The calculator shows your monthly payment, balloon amount due at term-end, total interest paid, and the true effective cost of credit on the deal.
On-the-road price the dealer is asking — VAT included.
10% of price · 10% is the SA norm.
Trade-in works exactly like a deposit — reduces what you finance.
Currently prime + 2% (SA prime is 10.25%, May 2026). Vehicle finance typically prices at prime + 1% to prime + 4%.
60 months is the SA mid-point. Longer term = lower monthly, more interest, longer time underwater on the loan.
Defers part of the loan to a final lump sum. Lowers the monthly but you still pay interest on the balloon balance every month — and you owe the lump sum at the end of the term.

Most SA vehicle finance is variable-rate — your actual instalment will rise or fall when SARB changes the repo rate. Try the affordability calculator to see the price you actually qualify for.

|---|---|---|
| Excellent | Prime + 0.5% to + 1% | 10.75% – 11.25% |

How an SA vehicle finance instalment works
SA vehicle finance is a fixed-instalment loan with an optional balloon (also called a residual). You pay the same fixed amount every month for the term, and if there's a balloon you owe a single lump sum at the end. Interest accrues every month on the full outstanding balance, including the unamortised balloon portion — which is why a balloon does not lower your monthly by the balloon percentage.
The formula is M = [i × (P × (1+i)ⁿ − B)] / [(1+i)ⁿ − 1], where P is the amount financed, B is the balloon, i is the monthly rate (annual ÷ 12), and n is the number of months. With B = 0 this simplifies to the standard amortisation formula. SA banks use this identically — what differs between WesBank, MFC, Standard Bank VAF, Absa and Nedbank is only the interest rate they offer you.
On top of the principal-and-interest instalment, the bank adds a monthly admin fee (R69 excl VAT, capped by NCA Regulation 42) and charges a once-off initiation fee at the start (R1,207.50 incl VAT for any agreement above R10,000). Comprehensive car insurance is mandatory and typically billed separately by your insurer — not by the bank.
Most SA vehicle finance is variable-rate, meaning your instalment changes when SARB changes the repo rate. A 1% rate hike on a R300,000 loan over 60 months adds about R130/month to your repayment.

12.25% over 60 months — small SUV (Corolla Cross, Jolion)

R400k car, 10% deposit, 30% balloon
12.25% over 60 months — same car with balloon
R1,700/month lower instalment but R108,000 lump sum due in month 60.
R600k bakkie, 15% deposit, 35% balloon
12.25% over 72 months — Hilux / Ranger SR

R150k used car, 0% deposit
13.25% (prime + 3%) over 48 months — used car loading
Used cars carry a higher rate. No balloon offered on older cars.
R800k luxury car, 20% deposit, 40% balloon
11.75% (prime + 1.5%) over 60 months — strong buyer
Premium bracket: bigger deposit + balloon keeps monthly manageable.

Frequently asked questions
How is a vehicle finance instalment calculated in South Africa?
SA vehicle finance uses an annuity-with-balloon formula: M = [i × (P × (1+i)ⁿ − B)] / [(1+i)ⁿ − 1], where P is the amount financed (vehicle price minus deposit and trade-in), B is the balloon payment due at the end, i is the monthly interest rate (annual ÷ 12), and n is the number of months. Interest accrues every month on the entire outstanding balance — including the balloon portion — which is why a 40% balloon does not give you a 40% lower monthly. On top of the instalment, banks add an NCA-capped monthly admin fee of about R69 and charge a once-off initiation fee of R1,207.50 (incl VAT) at the start.
What interest rate should I use?
Default to your bank's actual quote if you have one. If not, use SA prime (currently 10.25%, May 2026) plus a spread reflecting your profile: prime + 0.5% to + 1% if you're a top-tier earner buying a new car with 20% deposit, prime + 2% for the average buyer with 10% deposit on a new car, prime + 2.5% to + 3.5% for used cars or weaker credit, prime + 4% or higher for sub-prime. The default in this calculator (prime + 2% = 12.25%) reflects what most middle-income SA buyers actually get offered across WesBank, MFC, Standard Bank VAF and Absa.
Is a balloon payment a good idea on car finance?
Only if you have a clear plan for the lump sum at the end. A balloon defers part of the principal (usually 30–40%) to a single payment due at month 60 or 72, lowering your monthly by 20–30%. The trade-off: you still pay interest on the balloon balance every month AND you owe the lump sum at the end. Most balloon buyers cannot pay cash and refinance, adding 12–36 more months of interest. Worse: if the car's market value at month 60 is less than the balloon amount (very common on heavily depreciated SUVs), you cover the gap from your pocket. The math only works if you'll genuinely save the monthly difference and have the cash ready at term-end.
What is the prime lending rate in South Africa?
Prime is the benchmark rate that SA banks offer their lowest-risk customers. As of May 2026 it is 10.25%, made up of the SARB repo rate (6.75%) plus a fixed 3.50% bank margin. SARB's Monetary Policy Committee meets six times a year and adjusts repo to manage inflation; prime moves in lockstep. Vehicle finance is variable-rate by default, meaning a 1% repo hike adds about R130/month to a R300,000 loan over 60 months. SARB published a consultation paper in February 2026 proposing to phase out prime entirely in favour of direct repo-rate referencing — that change has no confirmed timeline yet.
How much deposit do I need for vehicle finance?
SA banks routinely offer 0% deposit vehicle finance to qualifying buyers, but a 10% deposit gets you a noticeably better interest rate — usually 0.5% lower over the life of the loan. A 20% deposit is the sweet spot: best rates, lower monthly, and you avoid being underwater on the loan in the early years. Trade-in value works exactly like a deposit. Don't forget the once-off NCA initiation fee (R1,207.50 incl VAT), the monthly admin fee (~R69/mo), and comprehensive car insurance (typically R800–R2,200/month, mandatory for any financed vehicle in SA).
What's the longest loan term I should take on a car?
60 months is the SA mid-point and the most defensible default. 72 months is fine if it gets you into a car that fits your life and you don't plan to trade it in early. 84 months is available at a few lenders for new cars only, but means you'll be underwater on the loan — owing more than the car is worth — for most of the term. If you crash, want to sell, or trade up, you cover the gap. Our calculator caps at 72 months for this reason. Shorter terms (36 or 48 months) save you a huge amount in total interest if you can carry the higher monthly.
What other costs are there besides the monthly instalment?
On top of the monthly instalment, budget for: (1) Comprehensive car insurance — required by every SA bank for financed vehicles, R800–R2,200/month depending on car value, your age and where the car sleeps. (2) Tracker subscription — R200–R500/month, usually financed into the loan. (3) Monthly admin / service fee — about R69 at most banks, NCA-capped. (4) Annual licence renewal — R200–R1,500 depending on tare weight. (5) Fuel and tyres — see our trip cost calculator for per-route running cost. (6) The balloon payment, if you took one — due in a single lump at the end of the term.
Can I settle my vehicle finance early?
Yes, the National Credit Act gives every consumer the right to settle a credit agreement early. The settlement amount is the outstanding capital plus any interest and statutory fees up to the settlement date — minus any unearned interest from future months. For loans under R250,000 there's no early-settlement penalty. For larger agreements, banks may charge a penalty equal to up to three months of interest on the outstanding balance — read your agreement. Early settlement is almost always worth it if you have the cash, because you stop the interest meter immediately. Extra monthly payments work the same way: every extra rand goes straight to capital.
