Monthly repayment tables for mortgages from £150,000 to £400,000 at current UK interest rates — across 25 and 30 year terms.

Moving from a 25-year to a 30-year term reduces monthly payments by roughly 8-10%. The trade-off is paying more total interest over the life of the loan. Many borrowers extend the term to make payments affordable now, then overpay when finances allow to bring the term back down.
A larger deposit means a smaller mortgage and a lower LTV, which typically unlocks better interest rates. Even moving from 90% to 85% LTV can reduce your rate by 0.2-0.4%, saving £50-£100 per month on a £250,000 mortgage.
Most mortgages allow overpayments of up to 10% per year without penalty. Overpaying reduces the outstanding balance, which reduces the interest charged each month. Even £100 per month extra on a £250,000 mortgage at 4.5% saves over £20,000 in interest and cuts almost 3 years off the term.
If you are on your lender’s standard variable rate (SVR), switching to a new fixed deal could save hundreds of pounds per month. SVRs are typically 6-7.5% — switching to a 4.5% fixed deal on a £250,000 mortgage saves approximately £270-£420 per month.
