How it's worked out

Figures use the standard repayment-mortgage formula (capital and interest, equal monthly payments): payment = loan × monthly rate ÷ (1 − (1 + monthly rate)−months). They assume the rate stays the same for the whole term — in practice you'll re-fix every few years. Product fees, valuation fees and overpayments are not included.

FAQ

What are the monthly repayments on a £280,000 mortgage?

At a 5% interest rate over 25 years, a £280,000 repayment mortgage costs £1,637 a month — £491,056 repaid in total over the term. At 4% the same mortgage is £1,478 a month, and stretching to 30 years at 5% lowers the payment to £1,503.

How does the term length change the cost?

Longer terms cut the monthly payment but increase the total interest dramatically. On £280,000 at 5%, a 15-year term costs £2,214 a month (£398,560 total), while a 35-year term costs £1,413 a month but £593,513 in total — the longer term repays far more interest for the same loan.

Are these figures exact quotes?

No — they are standard repayment-mortgage arithmetic (capital and interest, fixed rate for the whole term) to help you budget. A real offer depends on your deal period, fees, loan-to-value and credit profile, and rates change when a fixed deal ends. Interest-only mortgages cost less per month but repay none of the capital.
