Those figures are the legal ceiling, not a quotation. A bank lending R5 000 to a salaried customer with a clean bureau record will usually price well below the cap, and comparing offers is the only way to find out by how much. Read the numbers as the worst case you should be prepared for, and as a reminder that the term you choose changes the arithmetic in both directions.
Because the initiation fee and the service fee are fixed amounts in rand, spreading them over six months rather than thirty-six makes the effective annual rate look brutal even when the rand cost is modest. The reverse is just as true: the same R5 000 over three years attracts three years of interest and thirty-six service fees, so the total cost of credit climbs far past R2 090 even though each instalment feels comfortable. Neither term is automatically the cheaper one.
Ask every credit provider for two numbers on the quotation — the monthly instalment and the total cost of credit — and compare those side by side. Then check that the instalment still fits in the months when school fees, the medical aid shortfall and the December bills all land at once.
