Extending your mortgage term can lower your monthly payments, but it means you’ll take longer to pay off your mortgage and as a result pay more in interest over the lifetime of your loan.

The following illustration shows the impact of extending a mortgage term from 25 years to 35 years on an outstanding mortgage balance of £200,000 paying interest of 6%.

The current term

The repayments after the 10 year term extension

The monthly payments

£1,288.60

£1,139.53

The total amount to repay over your whole mortgage

£487,835.82

£642,357.82

The total amount of interest to pay

£287,835.82

£442,357.82

Total increase to the interest payable

£154,522.00

In this case, the APRC increases from 8.68% to 8.78% and the homeowner would pay an extra £154,522.00 in interest over the lifetime of their loan.
