What exactly is a car loan?

car loan is financing borrowed from a lender to purchase a vehicle. While most South Africans opt for a loan term of 60 to 72 months, this period can be adjusted. The borrowed amount, plus interest, must be repaid during this time.

The interest rate determines how much extra you'll pay back and is often the difference between an affordable car payment and financial strain.

The importance of understanding interest rates

The interest rate on your car loan plays a key role in determining your total repayment plan. For South Africans, as of 2025:

  • New cars: Interest rates range between 9% and 15%, depending on your creditworthiness.
  • Used cars: Interest rates are slightly higher, typically 10% to 20%.

By learning the basics of interest calculations, you can negotiate lower rates and save thousands of rands over your loan term.

How are car loan interest rates determined?

Car loan rates in South Africa are directly tied to the SARB's prime lending rate. Currently, at 11.75%, this rate is the baseline for determining interest. Whether your rate is higher or lower often depends on factors like:

  • Your credit score: A better score equals lower rates.
  • Loan term: Longer terms cost more in interest.
  • Vehicle type: New cars have lower rates than used ones.
  • Down payment: A larger deposit reduces your loan amount and your interest.

Simple vs. precomputed interest

South African lenders calculate interest in two main ways:

  • Simple interest: This is based on your loan balance. As you pay off your loan, the interest decreases.
  • Precomputed interest: Calculated on the total loan amount for the entire term, you pay more overall interest.

Most car loans in South Africa are based on simple interest, making extra payments a good strategy for reducing your balance faster.

5 Tips to secure the best car loan interest rate

  1. Check your credit score before applying

    • Aim for a score of 650 or above for lower rates.
    • Improve your score by paying off outstanding debts before applying.
  2. Shop and compare lenders

    • From banks to dealership loans, explore your options before committing.
    • Negotiate for better terms if you've secured pre-approval elsewhere.
  3. Avoid long loan terms

    • While a 72-month term offers lower monthly payments, a shorter term can save you significant interest.
  4. Put down a big deposit

    • A higher deposit reduces your overall loan balance and interest.
  5. Understand balloon payments

    • Though these lower monthly repayments, you'll need to pay a lump sum. Ensure you're financially prepared. We do not recommend this kind of payment. Here's why!
