Essential Car Finance Terms You Need to Know
1. Principal (or Capital Amount)
Definition: The actual amount of money you are borrowing to buy the car, before any interest is added. It is the purchase price minus your deposit.
Example: For a car costing R 250,000.00 with a R 30,000.00 deposit, the principal loan amount is R 220,000.00.
Why it matters: This is the base figure on which your interest is calculated. A lower principal means less interest paid.
2. Interest Rate
Definition: The percentage charged by the bank for lending you the money, expressed as an annual rate. In South Africa, it's often quoted as "Prime + X%".
Example: If the prime rate is 11.75% and your rate is "Prime + 2%", your interest rate is 13.75%.
Why it matters: This is the cost of borrowing. A lower rate saves you thousands of Rands over the loan term.
3. Deposit
Definition: An upfront cash payment you make towards the purchase price of the car. This reduces the amount you need to finance.
Why it matters: A larger deposit lowers your monthly repayments and the total interest you pay.
4. Balloon Payment (or Residual Value)
Definition: A large, lump-sum payment due at the end of the loan term. By deferring part of the cost, you can lower your monthly instalments.
Example: On a R 300,000.00 car, a 20% balloon payment means you will owe R 60,000.00 at the end of the loan.
Why it matters: While it makes monthly payments more affordable, it represents a significant future debt that must be paid or refinanced.
5. Amortisation
Definition: The process of paying off your debt through regular instalments over time. Each payment covers part of the interest and part of the principal.
Why it matters: Early in the loan, a larger portion of your payment goes toward interest. Understanding this explains why building equity (ownership) in the car starts slowly.
6. Loan Term (or Repayment Period)
Definition: The length of time you have to repay the loan, usually stated in months (e.g., 60 months for 5 years).
Why it matters: A longer term (e.g., 72 months) means lower monthly payments but significantly more interest paid overall. A shorter term means higher monthly payments but less total interest.
7. Total Cost of Credit (or Total Amount Payable)
Definition: The total amount you will have paid by the end of the loan term. This includes the principal amount plus all interest and any mandatory fees.
Example: Borrowing R 200,000.00 might result in a total cost of credit of R 275,000.00 after interest is added.
Why it matters: This is the most important figure to understand the real cost of the car. It is always higher than the car's sticker price.
8. Initiation Fee
Definition: A once-off fee charged by the credit provider to set up the loan agreement. By law in South Africa, this fee is capped at R 1,207.50 (including VAT) for loans under R 500,000.00.
Why it matters: This is an upfront cost that adds to the total amount you need to pay.
9. Monthly Service Fee
Definition: A separate monthly fee (often around R 69.00) charged by the bank for administering your loan account. It is not included in the capital and interest repayment calculation.
Why it matters: Your actual monthly debit order will be your repayment plus this fee.
10. Negative Equity
Definition: This occurs when you owe more on your car loan than the car is currently worth. It's also known as being "upside down" on your loan.
Why it matters: This can be a problem if you need to sell the car or if it is written off in an accident, as the insurance payout may not cover the outstanding loan balance.
Actionable Advice: How to Use This Knowledge
- Compare Apples to Apples: When looking at different finance offers, compare the Total Cost of Credit and the Interest Rate, not just the monthly payment.
- Ask for Definitions: If a salesperson or finance manager uses a term you don't understand, ask them to explain it in simple terms.
- Read the Contract Carefully: Before signing, ensure you understand every term and fee listed in the agreement.
- Beware of the Balloon: Fully understand the implications and size of a balloon payment before agreeing to it.
