Personal Loan Calculator

Under the National Credit Act, the maximum prescribed interest rate for unsecured personal credit agreements is calculated using a formula linked to the South African Reserve Bank repo rate. At most typical repo rate levels this works out to a rate in the low-to-mid twenties per cent per annum, though the precise cap changes when the repo rate changes. Always ask your lender for the rate expressed as an annual percentage and verify it falls within the current NCA cap.

With a reducing-balance method, interest each month is charged only on the remaining outstanding principal, so your interest cost falls as you repay the loan. A flat-rate calculation applies interest to the original loan amount for every month of the term, which results in a much higher effective annual rate and total cost. All NCA-compliant credit providers in South Africa are required to use the reducing-balance method for consumer credit agreements.

The calculator can include NCA-capped initiation fees and the monthly service fee when you enter them in the relevant fields, incorporating them into the total cost of credit figure. If you leave those fields blank, the output reflects interest and capital only, so your actual instalment from a lender will be slightly higher once regulated fees are added. Always request a pre-agreement statement and quotation from the lender so you can compare the full cost against the calculator result.

Yes, provided the lender is a registered credit provider under the NCA, the same amortisation formula and rate caps apply regardless of whether the provider is a bank, a retailer, or a smaller credit provider. Simply enter the loan amount, quoted interest rate, and term offered by any NCR-registered provider and the calculator will show comparable monthly instalment and total cost figures. This makes it straightforward to compare a bank offer against that of any other registered lender side by side.

The NCA gives you the right to settle a credit agreement early at any time, and the lender must provide you with a settlement balance that reflects only the outstanding capital plus interest accrued to the settlement date. Because this calculator uses reducing-balance amortisation, the outstanding balance at any point in your term is the present value of the remaining instalments, which you can estimate by re-running the calculator with the remaining term. Early settlement typically saves a notable amount compared with the total interest shown for the full original term.

South African credit providers use your credit bureau data, sourced from NCR-registered bureaus such as TransUnion, Experian, or Compuscan, to assess risk and set your personalised interest rate within the NCA cap. A higher credit score, built through consistent on-time payments and a low credit utilisation ratio, generally results in an offer closer to the lower end of the permissible rate range. Use the calculator to model both the best-case and worst-case rate so you understand the instalment range you may be offered before you apply.

The calculator on this page performs all computations locally in your browser based on the numbers you enter and does not require you to submit personal identifying information. If you proceed to a full loan application through a lender, that lender is required to handle your personal information in accordance with the Protection of Personal Information Act. Always review a lender's POPIA privacy notice before submitting any personal or financial documents.

DebiCheck is a South African Reserve Bank-mandated authenticated debit order system in which you, as the account holder, must electronically approve the debit order mandate with your bank before repayments can be collected. This provides stronger protection against unauthorised deductions compared with older debit order systems. When you accept a personal loan offer, your lender will initiate a DebiCheck authentication request to your bank, and it is important that you approve the correct amount that matches the monthly instalment shown in the loan agreement and confirmed by this calculator.
