How your mortgage payment is calculated
A repayment mortgage has a fixed monthly payment that covers the interest due that month plus a slice of the loan. Early on, most of each payment is interest. As the balance falls, more goes to the principal, which you can see in the schedule above.
The formula is P × r ÷ (1 − (1 + r)−n), where P is the loan, r the monthly interest rate and n the number of payments.
How to lower your monthly payment
- Bigger deposit: borrowing less cuts both the payment and the total interest, and can remove mortgage insurance.
- Longer term: spreads the loan over more payments but costs more interest overall.
- Better rate: even 0.25% makes a noticeable difference over 25–30 years. Compare lenders and brokers.

First-time buyers pay nothing up to £300,000 and 5% from £300,001 to £500,000, but lose the relief entirely above £500,000. Buying an additional property adds 5% to every band.
