  • Your lender must give you a pre-agreement quote showing the instalment, rate, fees and credit life insurance. Credit life insurance premiums are not included here — add them to compare quotes fairly.
  • Under the National Credit Act, maximum interest rates and fees are capped. If a quote looks too high, check it with the National Credit Regulator.

The formula

Amount financed = loan + initiation fee (if added to the loan) Instalment = financed × r ÷ (1 − (1 + r)^−n) + monthly service fee Total cost of credit = total repaid − amount borrowed

Credit life insurance is often added to personal loans. Ask for the monthly premium on your quote and add it to the instalment when comparing lenders.

The same loan with fees from a quote

Adding a capitalised initiation fee and a monthly service fee increases the true cost of the loan noticeably.

Frequently asked questions

What is the total cost of credit?

Everything you repay above the amount you borrowed — interest, the initiation fee, monthly service fees and (where applicable) credit life insurance. It is the best number for comparing loan quotes.

Is there a limit on personal loan interest rates?

Yes. The National Credit Act caps the interest rates, initiation fees and service fees lenders may charge, linked to the repo rate for interest. Your lender must give you a pre-agreement quote.

Should I take a longer term for a lower instalment?

A longer term lowers the instalment but increases the total interest and fees. Choose the shortest term you can comfortably afford.
