£250,000 mortgage: monthly repayments over 25 and 35 years

What a £250k mortgage costs at today’s rates

Average fixed rates jumped in autumn 2026: Moneyfacts recorded the average 5-year fix reaching 6% on 5 October for the first time in about three years, and it stood at 5.99% on 28 October, with the 2-year fix at 5.97%. Bank Rate has been 3.75% since the Monetary Policy Committee held it on 17 September 2026 (three members voted for a rise), and the next decision is on 5 November. That is why a tracker priced off Bank Rate currently looks cheaper than a fix — £1,425 a month at an assumed 4.75% — but its payment moves every time Bank Rate does. Every 1 percentage point on the rate changes the 25-year repayment on £250,000 by about £156 a month.

Around the national average. With a 10% deposit, £250k buys about £277,778 — 2% above the £273,037 UK average and below England’s £294,000. First-time buyers still pay no Stamp Duty below £300,000.

25 vs 35 years: total interest on £250,000

The term matters almost as much as the rate. At 5.99%, a 35-year term saves £185 a month compared with 25 years, yet the interest bill rises from £232,768 to £347,994. A 20-year term costs £180 more a month than 25 years but saves £53,255 of interest.

How the £250k balance falls: amortisation

In year one, £14,854 of your £19,311 of payments is interest and only £4,457 reduces the debt. Capital repaid overtakes interest in year 14, and half the loan is cleared by year 17 of 25. After a typical 5-year fix you would still owe about £224,798, which is the figure you would remortgage. That is why overpaying early has the biggest effect. Paying an extra £200 a month would save about £57,505 of interest and finish 5 years 4 months sooner.

How much salary do you need for a £250k mortgage?

Lenders start with an income multiple and then check your spending. At the common 4.5× income limit, a £250,000 mortgage needs £55,556 of gross household income — one earner on £55,556 or two on about £27,778 each. A smaller group of lenders will go to 5.5× for higher earners, certain professions or first-time buyers with strong credit, cutting the requirement to £45,455. The Bank of England limits each lender to 15% of new loans at 4.5× or more, so the higher multiples are not available to everyone.

The “payment share” columns show the 5.99%, 25- and 35-year repayment as a share of a single earner’s 2026/27 take-home pay (England, Wales & NI). Two earners on £27,778 take home more in total — about £3,920 a month — because each gets their own personal allowance, so the same loan takes 41% of joint take-home at 25 years.

Deposit, house price and Stamp Duty for a £250,000 mortgage

The loan-to-value (LTV) ratio decides both the price you can reach and the rate you are offered. A £250,000 mortgage at 90% LTV means a £277,778 home and a £27,778 deposit. Stamp Duty below uses the England and Northern Ireland rates in force since 1 April 2025 — the temporary £250,000 nil-rate band ended on 31 March 2025, and first-time buyer relief now covers only the first £300,000 (on homes up to £500,000).

At £277,778 a first-time buyer pays no Stamp Duty, while a home mover pays £3,889 — money that has to come from savings, not the mortgage. Buyers of a second home or buy-to-let pay a further 5% on the whole price. In Scotland and Wales, LBTT and LTT apply instead; use the Stamp Duty calculator for exact figures.

Stress test: could you afford a higher rate?

Under FCA rules lenders must check that a mortgage stays affordable if rates rise, especially for deals fixed for less than five years. Many lenders test against a rate a few points above the product rate or their reversion rate. At an illustrative 8.99% (today’s average 5-year fix + 3 points) the 25-year payment on £250,000 would be £2,096 — £487 a month more. If that would break your budget, consider a longer fix, a smaller loan or a bigger deposit. When a fixed deal ends the loan moves to the lender’s standard variable rate, which averaged 7.13% — £1,788 a month on this loan.
