What Does a R300,000 Car Loan Cost in South Africa?
At 13.75% over 6 years, a R300,000 car loan costs R6,141.63 per month and a total of R442,198 — with R142,198 going to interest. That interest represents 47% of the original loan amount.
South African car finance is typically priced at prime plus 2–4 percentage points. With the prime rate at 10.25% in 2026, most buyers are paying between 12.25% and 14.25%. A strong credit score (650+), a deposit of 10% or more, and applying through your own bank rather than dealer finance all help you secure a lower rate — which directly reduces both your monthly instalment and total cost.
To keep your finances healthy, your total monthly debt repayments (car, bond, personal loans) should ideally not exceed 30–35% of your gross income. That means a R6,141.63 car instalment calls for a gross income of at least R20,472 per month if it's your only debt commitment.

The Deposit Advantage: How It Changes Your Repayment
A 15% deposit of R45,000 on a R300,000 car reduces your financed amount to R255,000. Your monthly instalment drops from R6,141.63 to R5,220.39 — and you save approximately R66,330 in total interest over the life of the loan. That saving alone can cover a year of fuel costs.
Beyond the financial saving, a deposit also protects against negative equity — the situation where you owe more than the car is worth. Most new vehicles lose 15–25% of their value in the first year. Without a deposit, you're likely underwater on the loan for the first 18–24 months, which creates a gap between what insurance pays out (market value) and what you owe the bank if the car is written off.
If you're in a position to save before buying, even a 10% deposit makes a meaningful difference to both your monthly cash flow and long-term cost. Use the Savings Goal Calculator to plan how long it will take to save your target deposit amount.
