How to Use This Calculator
Switch Savings tab
Enter your current bond balance, your existing interest rate, remaining term, and the new rate being offered. Add an estimate of your switching costs (attorney fees R8,000–R15,000, bank initiation fee R6,900, Deeds Office R178 — typically R15,000–R35,000 in total). The calculator instantly shows your monthly saving, total savings over the term, and exactly which month you break even on the switching costs.
Should I Switch? tab
This tab adds two more fields: any cashback the new bank is offering and any early settlement penalty from your current bank (typically R0 under the National Credit Act). The verdict — "Worth switching" or "Not worth it" — is based on your net benefit after all costs.
How Bond Switching is Calculated
The monthly saving is simply the difference between the two PMT calculations:
Total savings = Monthly saving × months in common term
Break-even month = Switching costs ÷ Monthly saving
Net benefit = Total savings + Cashback − Switching costs − Penalty
Where PMT uses the standard bond repayment formula:
Worked Example
Kabelo has a R1,000,000 bond at 11.5% with 15 years remaining. His current monthly payment is R11,681.
Nedbank approaches him with a rate of 10.25% for the same 15-year term. His new monthly payment would be R10,905 — a saving of R776 per month.
Total switching costs are estimated at R25,000. Kabelo would break even on those costs in month 33 (just under 3 years), with 12 years of savings still remaining. Over 15 years, total savings are approximately R139,680 — well worth switching.
What Do Bond Switching Costs Include?
When you switch your bond to a new bank, you effectively cancel the existing bond and register a new one. The main costs are:
- Bond cancellation attorney fees: R3,500–R8,000 (to cancel the existing bond at Deeds Office)
- Bond registration attorney fees: R8,000–R15,000 (to register the new bond)
- Deeds Office bond cancellation fee: R178
- Deeds Office bond registration fee: R561–R1,738 depending on bond amount
- New bank initiation fee: Up to R6,900 (NCA maximum)
- 90-day notice period interest: Your current bank requires 90 days notice; interest continues to accrue during this period
Total costs typically range from R15,000 to R35,000 for a bond in the R800,000–R1,500,000 range.
Frequently Asked Questions
How much does it cost to switch your bond in South Africa?
Switching a bond typically costs R15,000–R35,000 in total. This includes bond cancellation attorney fees (R3,500–R8,000), new bond registration attorney fees (R8,000–R15,000), Deeds Office fees (R178 for cancellation plus R561–R1,738 for registration), and the new bank's initiation fee of up to R6,900. Some banks waive the initiation fee or offer cashback to attract switching clients.
How long does it take to switch a bond in South Africa?
The process takes approximately 3–4 months. Your current bank requires 90 days written notice of your intention to cancel. During this notice period, interest continues to accrue at your existing rate. The new bond must be registered at the Deeds Office before the existing bond is cancelled. Allow extra time for the new bank's credit assessment (2–4 weeks) and conveyancing process (4–8 weeks).
When is switching your bond worth it?
Switching is generally worth it when: (1) the rate reduction is at least 0.5% or more, (2) you have at least 10+ years remaining on your bond, and (3) your break-even period is less than 3 years. A 1% rate reduction on a R1,000,000 bond saves roughly R700–R800 per month, meaning switching costs of R25,000 are recovered in about 3 years with a decade or more of savings still ahead.
Can my current bank match the new bank's rate instead of switching?
Yes. Before going through the full switching process, negotiate with your current bank first. Present the competing offer in writing. Banks regularly reduce rates by 0.25%–0.75% for existing clients who threaten to leave. A rate match saves you all the switching costs and avoids the 3–4 month administrative process. If your bank refuses to match or come close, then switching becomes worthwhile.
Is there a penalty for cancelling your bond early?
Under the National Credit Act (NCA), South African banks cannot charge a penalty for early settlement of home loans registered after June 2007. However, the 90-day notice requirement means interest accrues for that period — which is effectively a cost of switching. Some older bonds (pre-2007) may have contractual early settlement penalties; check your original bond agreement.
