What does a £325,000 mortgage cost per month?
At 3.5% APR over a 30-year term, the monthly repayment on a £325,000 mortgage is about £1,459.40. Over the life of the loan you'd repay £525,382.28 in total — of which £200,382.28 is interest.
The same loan over 25 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.
