Important Note About Interest Rates
Our calculations assume the interest rate remains constant throughout the loan term. For variable rate loans (like most bonds), your actual monthly payments may change if interest rates rise or fall during your loan period.

Results shown are estimates for financial planning purposes only and do not constitute financial advice, a credit quote, or an offer of credit. Rates depend on your credit profile and lender. CalcLoan is not a registered financial services provider. Please consult a qualified financial advisor or contact your bank directly before making financial decisions.

Bond Information

Most South African bonds are linked to the prime lending rate, currently 10.5% (SARB, May 2026). Your bank may offer prime minus a percentage based on your credit profile. Even small extra payments of R500-R1,000 per month can cut years off your bond term and save you significant interest. Use the deposit field to calculate exactly how additional monthly payments reduce your total bond cost and shorten your repayment period.

Typical Ranges
Typical bond amounts range from R500,000 to R5,000,000 with current interest rates between 9% and 13%.
