NCA-regulated; typically R69/month excl. VAT.
Calculates your estimated monthly repayment, total interest, and total cost of credit for a South African business term loan. Enter the loan amount, interest rate, and term — the calculator applies the standard annuity formula used by SA lenders and shows you the full cost breakdown before you apply.
Key inputs explained
- Loan amount
- The total amount you want to borrow. Lenders typically require security or a strong track record for loans above R500,000.
- Interest rate
- Your quoted annual interest rate. SA bank business loans are usually prime-linked; alternative lenders often quote a monthly rate — convert by multiplying by 12.
- Loan term
- The repayment period in months. Shorter terms mean higher monthly repayments but significantly less total interest paid.
SA business loan rates are not regulated the same way as personal loans — they vary widely between banks and alternative lenders. Prime-linked rates (currently 10.50%) are common for established businesses, while newer businesses or those without security may pay 20–30%+ through fintech lenders. Always compare the total cost of credit, not just the monthly repayment.
Frequently Asked Questions
Business loan rates in South Africa typically range from prime (10.25%) to prime plus 5%–10% depending on business age, turnover, credit history, and security offered. The NCA caps personal loans at repo + 21% but commercial loans to businesses have no statutory rate cap. Alternative lenders typically charge higher rates than the major banks.
Factor in: initiation fee (charged upfront), monthly service fee, credit life insurance (often mandatory), and any early settlement penalties. Always compare the Total Cost of Credit (TCC) rather than just the interest rate — the NCA requires lenders to disclose the TCC clearly on the pre-agreement quote.
A balloon payment reduces monthly instalments during the term, freeing up cash flow. However, the balloon amount remains due at the end — typically refinanced, paid from business profits, or covered by asset sale. Ensure your business plan accounts for the balloon if you use one.
