Bond / Home Loan Calculator
A clearer first look at the bond payment behind the property price.
Calculator inputs
- Property price
- Deposit
- Annual interest rate
- Loan term
How the calculator works
The bond estimate subtracts your deposit from the property price, then calculates the payment on the remaining loan at the chosen interest rate and term.
Example calculation
For a R1,000,000 property, compare a R100,000 deposit with a R200,000 deposit. The larger deposit reduces the loan amount and the interest that accrues over time.
Frequently asked questions
- How much bond can I afford?
- Affordability depends on income, existing obligations, deposit, interest rate, term, and the lender's assessment. Start with a comfortable payment, not only the maximum approval.
- How much deposit do I need for a house?
- There is no single answer. A larger deposit reduces the loan amount, but you also need to budget for transaction costs, moving, repairs, and an emergency buffer.
- How do bond repayments change when interest rates move?
- A variable-rate bond's payment can rise or fall when the rate changes. Stress-test the monthly payment before committing to a long term.
