Guide

How to use this calculator

01
Enter the vehicle price
Type the asking price (or agreed price if you've negotiated) in rands. Use the retail value from a car listing, or get an estimated value free from our Car Checker tool.
02
Set your deposit
Slide the deposit to the amount you plan to put down (0–50%). A higher deposit means a lower loan amount, lower monthly payment, and less total interest paid over the term.
03
Adjust the term and interest rate
Choose a finance term between 12 and 84 months. Adjust the interest rate to match the offer from your bank or dealer — SA car finance is typically quoted as prime ± a margin.
04
Read your monthly estimate
The calculator instantly shows your estimated monthly instalment, total amount repaid over the full term, and the total interest cost — so you can see exactly what financing a car will cost you.
Understanding car finance in South Africa

Key finance terms explained

Prime rate
What is the prime interest rate?
The SA prime lending rate is the SARB repo rate plus 3.5%. As of mid-2025 the repo is 6.75%, making prime 10.25%. Your car finance rate is quoted as prime plus a margin (e.g. prime + 2.5%), depending on your credit score and the lender's risk assessment.
Balloon payment
What is a balloon / residual?
A balloon payment defers a lump sum (e.g. 20% of loan) to the end of the term, reducing your monthly payment. At the end of the term you must pay it in cash, refinance, or trade in the vehicle. SA banks typically allow up to 30–35% balloon on new cars.
Deposit
Do I need a deposit?
Most SA lenders offer 100% finance (no deposit required), but putting down 10–20% upfront reduces your loan amount, lowers your monthly instalment, and significantly reduces total interest paid. A deposit can also improve approval odds if your credit score is borderline.
NCA
National Credit Act (NCA)
The NCA governs all credit agreements in South Africa. Lenders must conduct an affordability assessment and may not grant credit if your debt-to-income ratio is too high. Finance agreements must disclose all fees, rates and total costs upfront. This calculator estimates payments — any actual credit offer will include initiation and service fees.
