Balance + current term + new term → monthly payment difference and total interest difference.

How to Use This Calculator
Enter your current bond balance, interest rate, and remaining term. Select a new term from the dropdown (5–30 years). If you are consolidating other debt (e.g. a car loan or credit cards) into the bond, enter that amount in the additional debt field — the calculator will add it to your balance.
The results show your current versus new monthly payment, the total interest under each scenario, and a warning if extending the term significantly increases your total interest cost.
What Is Bond Restructuring?
Bond restructuring means changing the terms of your existing home loan — typically the repayment term — with your current bank. The most common reasons are:
- Extending the term to reduce monthly payments during financial hardship
- Shortening the term when your income increases and you want to pay less total interest
- Debt consolidation — rolling high-interest debt (personal loans, credit cards) into your home loan at a lower rate
Restructuring with your current bank is usually simpler than switching — no new conveyancing is required, and your bond registration stays the same.
Worked Example
Fatima has a bond balance of R900,000 at 10.25% with 15 years remaining. Her current monthly payment is R9,805 and total remaining interest is R864,900.
Scenario A — Extend to 20 years: Monthly payment drops to R8,829 (saving R976/month). However, total interest increases to R1,219,000 — an extra R354,000 in interest over the full term.
Scenario B — Shorten to 10 years: Monthly payment rises to R11,761 (R1,956 more per month). Total interest drops to R511,320 — saving R353,580 in interest.
The right choice depends entirely on Fatima's cash flow needs. If she is facing hardship, extending buys breathing room. If she has surplus income, shortening saves a significant amount.
Debt Consolidation: Know the Risks
Rolling short-term debt (car loans, credit cards) into a 20-year bond can significantly reduce your monthly payment, but it dramatically increases total interest paid if you do not reduce the term.
Monthly: R2,649 | Total interest: R58,940
Same R100,000 rolled into bond at 10.25% over 20 years:
Monthly: R979 | Total interest: R134,960 (R76,020 more!)
If you consolidate, always try to keep your monthly payment the same or higher to reduce the outstanding balance faster, or set a plan to pay off the consolidated amount well before the bond ends.
Frequently Asked Questions
Can I extend my bond term in South Africa?
Yes. You can approach your bank and request an extension of your bond term, typically up to a maximum of 30 years from the original registration date (not from today). Banks usually accommodate this during periods of financial difficulty, though they may require proof of hardship. The process is handled administratively — no new Deeds Office registration is required.
Does extending my bond term save money?
Extending reduces your monthly payment but significantly increases your total interest paid. For a R900,000 bond at 10.25%, extending from 15 to 20 years saves R976/month but costs an extra R354,000 in total interest. Only extend if you genuinely need monthly cash flow relief — and try to make extra payments to recover lost ground when finances improve.
Is it a good idea to consolidate debt into my bond?
It can be — if you are disciplined. Consolidating high-rate debt (20%+ credit cards) into a home loan at 10.25% reduces your interest rate. But if you extend the term, you pay more total interest even at the lower rate. The strategy works best if you: (1) keep your monthly payment the same after consolidation, and (2) pay off the consolidated amount within the original short-term debt period.
What is the maximum bond term in South Africa?
South African banks typically offer home loans for a maximum of 30 years. The maximum term is calculated from the original bond registration date, not from a restructuring date. If your original 20-year bond has 15 years remaining, you may be able to extend it by up to 10 more years (back to the original 30-year maximum).
Will restructuring my bond affect my credit score?
A normal term extension or restructuring requested proactively (not under debt review) generally has a minimal impact on your credit score — it is simply a change in loan terms. However, if the restructuring is a result of payment difficulties, it may be noted on your credit profile. Formal debt review (under the NCA) has a significant negative impact and remains on your credit record for a period after completion.
