What does a £500,000 mortgage cost per month?
At 5.25% APR over a 35-year term, the monthly repayment on a £500,000 mortgage is about £2,603.72. Over the life of the loan you'd repay £1,093,560.39 in total — of which £593,560.39 is interest.
The same loan over 30 years would be cheaper overall but higher each month. Stretching the term reduces the monthly cost but increases lifetime interest.
How to lower the repayment
- Increase your deposit to reduce the loan amount.
- Improve your credit score before applying — even a 0.25% rate cut saves thousands.
- Compare whole-of-market brokers, not just your high-street bank.
- Consider overpayments — most UK lenders allow 10% per year fee-free.
