You do rough mental arithmetic — 22% of thirty grand is R6,600 a year, so R13,200 over two years. Add that to the principal and you're thinking you'll repay somewhere around R43,200. Close enough, you figure. You sign. Here's what you actually repay. In March 2026, I ran the same scenario — R30,000, 24 months — through the public calculators of four major SA lenders. African Bank's calculator returned a monthly repayment of R1,871.11. Multiply by 24: R44,906. That's R14,906 for the use of R30,000 over two years. Capitec, the cheapest of the four, came in at R38,705. The spread between the best and worst deal on an identical loan: R6,201. That's not a rounding error. That's a school term's fees, two months of groceries, or the deposit on a car service. .The gap isn't hidden in fine print. It's sitting in plain sight across three line items that most borrowers never add up before they commit. The first hit comes immediately: the initiation fee. Under current NCA caps (National Credit Regulations, Schedule 2), a lender can charge up to R1,207.50 plus 10% of the loan amount above R10,000, subject to a maximum of R2,785. Both Capitec and Nedbank charge exactly R1,207.50 on a R30,000 loan — collected upfront or capitalised into your balance on day one. You borrowed R30,000. The interest clock starts on a larger number. .Read more:.Future SA interest rates? Global retreat from emerging-market bonds may be a blessing.The second line item runs every single month: the service fee. The NCA caps this at R69 per month. Both Capitec and Nedbank charge exactly R69.00 — R1,656 across 24 months. It is a flat charge that doesn't reduce as your balance falls. In the final months of the loan, when your outstanding principal might be R3,000, you are effectively paying a fee equivalent to more than 2% of your balance per month, on top of interest. The third cost is credit life insurance — and this is where most borrowers leave money on the table, because almost none of them know what the NCA actually permits. A lender can require you to hold credit life cover for the duration of the loan. What they cannot do, under the Credit Life Insurance Regulations that took effect in August 2017, is force you to take their product. Section 106 of the NCA and Regulation 7 give you an explicit right to substitute the lender's policy with any other policy that meets the minimum benefit requirements — death, permanent disability, temporary disability, and unemployment cover. If you already hold a comprehensive life policy, you may be able to cede it to the lender as a loss payee instead of paying a separate monthly premium. Capitec's first-month premium onthis loan is R124.83. Nedbank's is R109.23. Over 24 months, that adds up to between R1,600 and R1,800 — money a borrower with adequate existing cover is paying twice. In practice, the process of exercising this right — providing a policy schedule, having it assessed for adequacy, waiting for approval — is slow enough that most borrowers give up before the loan is disbursed. .Now here is the part that makes the rate-comparison habit so dangerous. When I compared Capitec and Nedbank's full breakdowns side by side, the initiation fee was identical. The monthly service fee was identical. Even the insurance premium was within R15 of each other in month one. Every fee that borrowers typically ignore — identical. The entire R3,608 difference in total cost of credit between the two products is explained by one thing: the interest rate. 12.25% versus 18%. .This cuts both ways. When fees are standardised at NCA caps across lenders, the rate actually does matter — but only once you know the fees are equal. The borrower who skips the rate comparison and shops on monthly repayment alone will never know this. Theborrower who compares rates without checking fees will be caught out the moment one lender charges a higher initiation fee or capitalises costs differently. Here is what all four calculators returned on 6 March 2026: .Two things stand out beyond the TCC figures. First, African Bank — the most expensive product by R6,201 — does not disclose their interest rate on their public calculator at all. It is worth noting that their credit life product covers a broader range of events than the NCA minimum — including lay-offs, short time, and compulsory unpaid leave — which may partly explain the higher cost. Second, Nedbank is the only lender that displays the total cost of credit by default, without requiring any additional clicks. They also explicitly confirm zero early settlement fees and zero late penalty fees — information no other calculator in this comparison volunteered. The NCA created a single number that captures all of this: the total cost of credit, or TCC. It is the rand figure representing everything you will pay over the life of the loan — principal, interest, initiation fee, every service charge, all insurance premiums, all fees inclusive of VAT. Lenders are legally required to calculate and disclose it. Of the four lenders tested here, one shows it by default, one hides it behind a button, and two require you to multiply the monthly repayment yourself and hope you remember to add the initiation fee. .Read more:. How to invest during a high interest rate era.Before you sign anything — before you complete a credit application — ask one question: what is the total cost of credit, in rands, over the full loan term? Not the monthly repayment. Not the rate. The TCC. If the number on the calculator doesn't show it, the lender is making a choice about what you see before you commit. That choice is not made in your interest. .*Thabo Mthembu is a Senior Financial Writer at LoanHub24.co.za. He writes about personal finance and the lending industry for South African audiences.
