The Minimum Payment Trap: Why Your Credit Card Could Take 20 Years to Pay Off
Last reviewed:
The minimum payment on a South African credit card is typically 3% of the outstanding balance or R200, whichever is greater. This sounds manageable — but it is a trap that can keep you in debt for over a decade and cost you more in interest than the original balance.
The Math Behind the Trap
On a R30,000 balance at 20.75% interest, the minimum payment starts at R900 (3% of R30,000). But as you pay down the balance, the minimum shrinks — R870, R840, R810 — until it hits the R200 floor. Meanwhile, interest keeps accumulating. The result: it takes over 13 years and costs over R20,000 in interest just to pay off the original R30,000.
Five Strategies Compared
The calculator shows five payoff scenarios side by side. Paying just R500 extra per month cuts payoff time roughly in half and saves thousands in interest. A fixed payment of R2,500 per month (about R30,000 ÷ 12) clears the debt in about a year with much less interest.
The Key Insight
Never pay only the minimum. Set a fixed monthly payment amount that is at least double the initial minimum, and keep paying that amount even as the minimum decreases. This is the simplest and most effective strategy for most people.
