Why term length matters

A longer term can reduce the monthly payment estimate but may increase the total interest paid. A shorter term can increase monthly payments and may not be affordable for every borrower.

Your home may be repossessed if you do not keep up repayments on your mortgage.

Frequently asked questions

Can I choose any mortgage term? +
No. Lenders set maximum terms and assess affordability, age, income, property and repayment type.
What happens if the payment is too low? +
If the payment does not cover enough interest and capital, the calculator will show that the balance is not repaid under the assumptions entered.
Does this replace lender affordability checks? +
No. It is an estimate only and does not confirm eligibility, rates, fees or suitability.
