Interest is only the headline. What you repay is built from four parts, each capped separately in regulation under the National Credit Act, and comparing lenders on the rate alone hides most of the difference between them. Ask for the total cost of credit in rand, which the pre-agreement quotation must state, and compare that single figure across offers on the same amount and the same term.
The four things you are paying for
Interest on unsecured credit is capped at the repo rate plus 21% a year, which puts the ceiling near 28% at 2026 repo levels. Short-term credit of up to R8 000 repaid within six months is capped monthly instead: 5% a month on your first such loan in a calendar year and 3% a month on any after it. On top of interest sit a once-off initiation fee, calculated as R165 plus 10% of the amount above R1 000 to a maximum of R1 050 before VAT, a monthly service fee capped at R60 before VAT, and credit life cover capped at R4.50 for every R1 000 you owe.
Why the same rand can cost so differently
Borrow R5 000 for one month from a short-term office and the cost is uncomfortable but contained. Borrow the same R5 000 and roll it forward for four months and you pay the monthly charge four times over, on a category priced for weeks rather than seasons. The same R5 000 as a personal loan over twelve months carries a far lower monthly cost and a service fee you pay twelve times. Neither product is wrong. Matching the product to how long you genuinely need the money is what keeps the total sensible.
One clause worth reading before you sign
Credit life cover is compulsory on most agreements, and you are entitled to substitute a policy you already hold rather than take the lender's. On a small loan it is a few rand a month; on R150 000 over five years it is not. Ask what the cover costs in rand, ask whether settling early carries a penalty, and ask whether the rate is fixed or linked to the repo rate. Put those questions to the consultant while the quotation is still a quotation.
