How to Use This Calculator
Enter your bond amount, select your bank (each has different cashback rates), and specify the interest rate offered and bond term. The calculator shows the gross cashback amount and the net amount after tax.
Switch to the "Cashback vs Lower Rate" tab to compare a cashback offer against an alternative offer with a lower interest rate but no cashback. This comparison shows which deal saves more over the full bond term — the answer may surprise you.
Cashback Tax Rules
Cashback received from a bank on a home loan is classified as interest income under Section 10(1)(i) of the Income Tax Act. The first R23,800 of interest income per year is tax-free for individuals under 65, and R34,500 for those 65 and older. If your total interest income (including savings accounts, money market funds, etc.) exceeds these thresholds, the excess is taxed at your marginal rate.
Worked Example
Kabelo is switching his R1,200,000 bond from Standard Bank to Absa, which offers 2.5% cashback at a rate of 10%.
His gross cashback is R1,200,000 × 2.5% = R30,000.
Kabelo is 38 years old and earns R5,000/year in savings account interest. His total interest income is R30,000 + R5,000 = R35,000. After the R23,800 exemption, R11,200 is taxable. At his 36% marginal rate, tax is approximately R4,032.
Net cashback: R25,968. If applied to his bond, this reduces the principal and saves an additional ~R65,000 in interest over 20 years.
However, if another bank offered him 0.25% lower rate with no cashback, the lower rate would save approximately R86,000 over 20 years. In this case, the lower rate is the better long-term deal.
Frequently Asked Questions
Is home loan cashback taxable in South Africa?
Yes. Cashback from a home loan is classified as interest income and is taxable. However, the first R23,800 of total interest income per year is exempt for individuals under 65, and R34,500 for those 65 and older. If your total interest income (cashback plus savings, money market, etc.) stays below the exemption threshold, you pay no tax on the cashback.
What is a cashback claw-back clause?
Most banks include a claw-back clause in their cashback offers. This means if you close or switch your bond within a specified period (typically 5 years), you must repay a pro-rata portion of the cashback. For example, if you received R30,000 cashback and switch after 3 years of a 5-year claw-back period, you may owe back R12,000 (2/5 of the cashback). Always read the offer letter carefully.
Which South African bank offers the best cashback on home loans?
Cashback offers change frequently and depend on your profile. As of 2026, Absa typically offers up to 3% for bond switches, Nedbank up to 3%, Standard Bank up to 2.5%, and FNB up to 2%. Capitec does not offer cashback but instead provides a competitive rate (often sub-prime). Use a bond originator to get competing offers from all banks simultaneously.
Should I take cashback or a lower interest rate?
In most cases, a lower interest rate saves more over the full bond term than a cashback offer. A 0.25% rate reduction on a R1.2M bond over 20 years saves approximately R86,000 in interest, while a 2.5% cashback (R30,000) applied to the bond saves about R65,000. However, cashback gives you immediate cash — useful for moving costs, renovations, or paying off high-interest debt. Use the "Cashback vs Lower Rate" tab above to compare your specific offers.
What should I do with my home loan cashback?
The most financially advantageous use of cashback is to apply it directly to your bond as a lump sum payment. This reduces your principal immediately, saving significant interest over the bond term. Other smart uses include paying off high-interest debt (credit cards at 21% rather than your bond at 10.25%) or covering transfer and moving costs. Avoid spending it on depreciating items or lifestyle expenses.
