A £250,000 repayment mortgage at 4.5% over 25 years costs approximately £1,390 per month. Your actual monthly payment depends on the interest rate you are offered and the mortgage term you choose. This guide shows the full range of monthly costs from 2% to 6% across 20, 25, and 30-year terms.

Interest-Only vs Repayment
Most residential mortgages are repayment (capital and interest). Interest-only mortgages are largely restricted to buy-to-let investors, though some specialist lenders offer them to high-income residential borrowers.
| Rate | Interest-only monthly payment |
|---|---|
| 2.0% | £417/month |
| 3.0% | £625/month |
| 4.0% | £833/month |
| 5.0% | £1,042/month |
| 6.0% | £1,250/month |
With interest-only, you pay less each month but owe the full £250,000 at the end of the term. You need a credible repayment vehicle (investments, property sale, pension lump sum) to pay it off.
Worked Example
James and Claire are buying their first home. They need a £250,000 mortgage. They are offered a 2-year fixed rate at 4.8%, switching to their lender’s standard variable rate (SVR) after 2 years. Their monthly payment on the fixed rate is £1,432. Over the 2-year fix they repay £34,380 total — of which around £-76,706 reduces the capital. After 2 years, they remortgage to a new deal to avoid the SVR.
What Salary Do You Need for a £250,000 Mortgage?
Lenders assess affordability using an income multiple, typically 4–4.5x annual income.
| Income multiple | Single applicant income needed | Joint income needed |
|---|---|---|
| 4.0x | £62,500 | £31,250 each (if equal) |
| 4.5x | £55,555 | £27,777 each (if equal) |
| 5.0x (some lenders) | £50,000 | £25,000 each (if equal) |
| 5.5x (specialist) | £45,454 | £22,727 each (if equal) |
These are illustrative. Lenders also consider your outgoings, credit score, age, and existing debt. The income multiple is the first check; affordability stress testing is the second.
Deposit Required to Get a £250,000 Mortgage
The mortgage is the loan amount. The property you buy is worth more — the difference is your deposit.
| Deposit % | Property value | Deposit amount | LTV |
|---|---|---|---|
| 5% deposit | £263,157 | £13,157 | 95% |
| 10% deposit | £277,777 | £27,777 | 90% |
| 15% deposit | £294,117 | £44,117 | 85% |
| 20% deposit | £312,500 | £62,500 | 80% |
| 25% deposit | £333,333 | £83,333 | 75% |
A larger deposit means a lower LTV, which typically qualifies you for better interest rates — reducing your monthly payment and total cost.
How to Reduce Your Monthly Payment
- Extend the term — moving from 25 to 30 years reduces the monthly payment but increases total interest paid significantly
- Increase your deposit — a lower LTV usually gets you a better rate
- Improve your credit score — higher scores qualify for lower rates; see how to improve your credit score UK
- Overpay when you can — reducing the balance faster means you pay interest on less for fewer years
- Remortgage regularly — do not drift onto the SVR; remortgage 3–6 months before your fixed rate ends

Even a 1% difference in interest rate costs tens of thousands of pounds over a 25-year term on a mortgage this size. Shopping around at each remortgage is essential.
