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 £70,000 mortgage?
At a 5% interest rate over 25 years, a £70,000 repayment mortgage costs £409 a month — £122,764 repaid in total over the term. At 4% the same mortgage is £369 a month, and stretching to 30 years at 5% lowers the payment to £376.
How does the term length change the cost?
Longer terms cut the monthly payment but increase the total interest dramatically. On £70,000 at 5%, a 15-year term costs £554 a month (£99,640 total), while a 35-year term costs £353 a month but £148,378 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.
