How much are mortgage repayments on a £350,000 mortgage in the UK?
A £350,000 repayment mortgage at 4.5% over 25 years costs approximately £1,945/month (£583,624 total). At 5%, monthly payments rise to about £2,046 (£613,820 total). Interest-only at 4.5% costs £1,313/month, but the £350,000 capital is still owed at the end.
Full answer
For a £350,000 capital-and-interest repayment mortgage in the UK, monthly payments depend on rate and term. 25-year term: 4.0% £1,847/month (£554,229 total); 4.5% £1,945/month (£583,624); 5.0% £2,046/month (£613,820); 5.5% £2,149/month (£644,792); 6.0% £2,255/month (£676,516). 30-year term: 4.0% £1,671/month (£601,543); 4.5% £1,773/month (£638,423); 5.0% £1,879/month (£676,395); 6.0% £2,098/month (£755,434). Interest-only at 4.5%: £1,313/month, with the full £350,000 owed at the end. This borrowing level typically needs gross household income of around £78,000 to £88,000 under standard income multiples, and lenders will stress-test affordability against a higher notional rate to make sure repayments remain manageable if rates rise. A 10% deposit on a £389,000 property (90% LTV) opens most lenders. Use the mortgage calculator to compare terms and see how overpayments reduce total interest.
