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 £750,000 mortgage?
At a 5% interest rate over 25 years, a £750,000 repayment mortgage costs £4,384 a month — £1,315,328 repaid in total over the term. At 4% the same mortgage is £3,959 a month, and stretching to 30 years at 5% lowers the payment to £4,026.
How does the term length change the cost?
Longer terms cut the monthly payment but increase the total interest dramatically. On £750,000 at 5%, a 15-year term costs £5,931 a month (£1,067,571 total), while a 35-year term costs £3,785 a month but £1,589,766 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.
