The NCA Rate Cap Explained: Why Your Loan Can't Cost More Than 28%
By Finance Atlas Editorial — June 2026 · 5 min read
The single most important consumer protection in South African credit law is the NCA rate cap — yet most borrowers don't know it exists. Here's what it is, how it works, and how to use it.
What the Cap Actually Says
Under Regulation 42 of the National Credit Act, the maximum interest rate a lender can charge on an unsecured personal loan is the South African Reserve Bank repo rate plus 21%. With the repo rate at 7.00% (as of May 2026), the cap sits at 28% per year. This is a hard legal ceiling — no lender, registered or not, can charge you more than this on a personal loan.
The cap is different for different types of credit. Mortgage agreements have a lower cap (repo + 12%, currently 19%). Vehicle finance falls under the general unsecured cap if there's no balloon, or a slightly different structure if there is. Credit cards fall under the same unsecured cap as personal loans. The cap moves when the SARB moves the repo rate — so when rates rise, the cap rises with them, and lenders can legally charge more. When rates fall, the cap falls too.
Why the Cap Matters
Before the NCA (which took full effect in 2007), there was no cap on unsecured credit interest rates. Lenders could — and did — charge 30%, 40%, even 60% per year to borrowers who had no other options. The micro-lending industry in particular was notorious for trapping borrowers in cycles of debt where the interest alone exceeded their income. The NCA rate cap ended this practice for registered lenders.
The cap doesn't just protect you from one bad loan — it protects the entire credit market. Without it, lenders would compete on who could extract the most from the most vulnerable borrowers, driving rates up across the board. The cap forces lenders to compete on service, speed, and underwriting instead of on who can charge the most.
How to Check If Your Rate Is Legal
Pull your pre-agreement quote (it's your right under Section 92 of the NCA). Find the annual interest rate — not the monthly rate, not the flat rate, the annual percentage rate (APR). Add 21 to the current repo rate (available on the SARB website). If your quoted rate is above that number, the loan is illegal.
Some lenders try to disguise the rate. A 'monthly rate of 5%' sounds like 5% per year — but it's actually 60%+ when annualised. A 'flat rate of 10%' on a 12-month loan means you pay 10% of the original balance every month, which is also far above the cap when calculated properly. Always insist on the APR in writing. If the lender can't or won't provide it, walk away.

What to Do If a Lender Quotes Above the Cap
If a registered lender quotes you a rate above the NCA cap, refuse to sign, get the quote in writing, and report them to the National Credit Regulator (NCR). The NCR can fine the lender, suspend their registration, and in serious cases refer the matter for prosecution. You should also report them to the Credit Ombud if the NCR process is slow.
If an unregistered lender — a loan shark, a Facebook 'lender', a doorstep lender — quotes you above the cap, walk away immediately. Unregistered lenders operate outside the NCA entirely, which means they're breaking the law by lending at all. Any agreement you sign with them is unenforceable, but they may still try to collect through intimidation. Do not give them your banking details, your ID, or any money upfront.
The Cap Is a Floor, Not a Ceiling on Cost
The rate cap limits the interest rate, but it doesn't limit the total cost of the loan. A 28% loan over 72 months is still extremely expensive — the total interest on a R50,000 loan at 28% over 72 months is over R48,000, nearly doubling the amount you repay. The cap protects you from illegal rates, but it doesn't protect you from your own bad decisions about term and amount.
Use the cap as a sanity check, not as a target. The best borrowers get rates well below the cap — prime + 5% to prime + 10% (15.5% to 20.5%) is achievable with a strong credit profile. If you're being quoted at or near the cap, it's a sign your credit profile is weak, and you should consider whether borrowing at that rate is the right move at all. Sometimes the best loan is no loan.
