£275,000 mortgage: monthly repayments over 25 and 35 years

What a £275k 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%. On 5 November 2026 the Monetary Policy Committee raised Bank Rate from 3.75% to 4.00% (eight votes to one; one member wanted 0.5 points), and the next decision is on 17 December. Trackers move with Bank Rate straight away, while fixed rates had already priced in much of the rise. That is why a tracker priced off Bank Rate currently looks cheaper than a fix — £1,608 a month at an assumed 5.00% — but its payment moves every time Bank Rate does. Every 1 percentage point on the rate changes the 25-year repayment on £275,000 by about £172 a month.

Around the national average. With a 10% deposit, £275k buys about £305,556 — 12% above the £273,037 UK average and above England’s £294,000. At that price first-time buyers start paying 5% Stamp Duty on the slice above £300,000.

25 vs 35 years: total interest on £275,000

Longer terms are now the norm for first-time buyers, but they are expensive. At 5.99%, a 35-year term saves £204 a month compared with 25 years, yet the interest bill rises from £256,044 to £382,794. A 20-year term costs £198 more a month than 25 years but saves £58,581 of interest.

How the £275k balance falls: amortisation

In year one, £16,339 of your £21,242 of payments is interest and only £4,902 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 £247,278, which is the figure you would remortgage. Overpayments made in the first few years therefore cut the most interest. Paying an extra £200 a month would save about £58,924 of interest and finish 5 years sooner.

Deposit, house price and Stamp Duty for a £275,000 mortgage

The loan-to-value (LTV) ratio decides both the price you can reach and the rate you are offered. A £275,000 mortgage at 90% LTV means a £305,556 home and a £30,556 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 £305,556 a first-time buyer pays £278 (5% of the slice above £300,000), against £5,278 for a home mover. 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.

How much salary do you need for a £275k mortgage?

The quick rule of thumb is the loan-to-income (LTI) multiple. At the common 4.5× income limit, a £275,000 mortgage needs £61,111 of gross household income — one earner on £61,111 or two on about £30,556 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 £50,000. 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 £30,556 take home more in total — about £4,253 a month — because each gets their own personal allowance, so the same loan takes 42% of joint take-home at 25 years.

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 £275,000 would be £2,306 — £536 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% — £1,967 a month on this loan.
