Mortgage repayments,
made understandable.

A monthly repayment estimate has three moving parts: how much you borrow, the interest rate and the time allowed to repay it.

Borrowed amount + interest + time

Your deposit reduces the borrowed amount. The interest rate and term then shape the estimated monthly repayment.

1. Mortgage balanceThe purchase price minus the deposit is the amount you may need to borrow.
2. Interest rateA higher rate generally increases the monthly repayment and the interest paid over time.
3. TermA longer term can lower the monthly amount, while extending the period over which interest is charged.

Try scenarios, not one answer

Enter a property price and deposit, then compare more than one rate and term. The purpose is to understand the trade-off, rather than to find a single “correct” number.

What this kind of calculator cannot know

It cannot decide whether a lender will approve a mortgage, what rate will be offered, or the exact payments under a specific product. Lender criteria, fees, insurance and your own circumstances can all affect the real result.

A useful way to plan

Use the repayment calculator with the deposit and full home-buying budget calculators. That lets you test the upfront cash you need separately from the monthly amount you would need to manage.
