Using the calculator is simple. Drag the three sliders to set your desired loan amount (from R500 to R250,000), the annual interest rate quoted by the lender, and the repayment term in months. The results update instantly, showing your estimated monthly instalment, the total amount you will repay over the full term, and how much of that is interest.
Try adjusting the term to see how a shorter loan saves on interest, or increase the amount to understand the impact on your monthly budget. This helps you find the balance between an affordable monthly payment and the lowest total cost.
Understanding the Results
- Monthly Payment: The fixed amount you pay each month. This covers both the principal (the amount borrowed) and the interest charged by the lender. Keep this within 30% of your take-home pay for a comfortable budget.
- Total Repayment: The full amount you will pay over the entire loan term, including all interest. This is the true cost of your loan.
- Total Interest Paid: The difference between the total repayment and the original loan amount. A shorter term or lower interest rate reduces this figure significantly.
Tip: The calculator uses the standard amortisation formula and does not include once-off initiation fees (up to R1,207.50) or monthly service fees (up to R69) regulated by the NCA. Ask your lender for a full quote before signing.
