Rent or Buy

Buy vs Rent Calculator UK

Compare the true cost of buying and renting, including stamp duty, maintenance, and what your deposit could earn if invested.

Should I buy or rent in the UK in 2025?

Buying wins if you plan to stay long enough for equity to build and property appreciation to outpace your alternative investment returns. Renting wins when house prices are stretched, interest rates are high, or you need flexibility. In 2025, UK mortgage rates remain elevated compared to the 2010s, but rents have also risen sharply. The right answer depends on your local market, your deposit size, and your time horizon.

The hidden cost most calculators ignore

Most buy-vs-rent comparisons look only at mortgage payments versus rent. That misses the opportunity cost of your deposit. When you buy, your deposit is locked in your property. A £35,000 deposit invested at 7% per year grows to roughly £69,000 after 10 years. This calculator models both the equity you build and the investment pot you would accumulate by renting, so you can compare them directly.

How stamp duty affects the decision

SDLT is an immediate, non-recoverable cost. On a £350,000 purchase, a non-first-time buyer pays £7,500. That money earns no return and must be recouped through property appreciation before buying breaks even. A first-time buyer on the same property pays just £2,500 under the 2025 rates, giving buying a meaningful head-start.

When does buying beat renting?

Buying tends to win with a large deposit, strong property appreciation, a long time horizon, and high rent relative to your mortgage payment. Renting tends to win with high mortgage rates, a short horizon, a small deposit, or strong investment returns. The break-even year in the results above is the point where these forces cross.

Frequently asked questions

Is it cheaper to buy or rent in the UK right now?
It depends on location, deposit size, mortgage rate, and how long you plan to stay. In high-cost areas like London, renting is often cheaper short-term because house prices are high relative to rents and stamp duty is a large upfront barrier. Use the calculator above to find your personal break-even year.
What is the opportunity cost of a deposit?
It is the investment return you give up by locking your deposit into property instead of investing it. A £35,000 deposit invested in an index fund at 7% per year grows to roughly £69,000 in 10 years. This calculator models that, so you can see whether your equity beats what you would have earned by renting and investing.
How is stamp duty calculated for first-time buyers in 2025?
From 1 April 2025, first-time buyers pay 0% on the first £300,000 and 5% on the portion between £300,001 and £500,000. No relief applies above £500,000. On a £350,000 purchase a first-time buyer pays £2,500, versus £7,500 for someone who has owned before.
Does this calculator work for Scotland or Wales?
Not yet. It uses SDLT rates for England and Northern Ireland only. Scotland uses LBTT and Wales uses LTT, both with different bands. If you are in Scotland or Wales you can still use the calculator by adjusting the buying costs field to approximate your actual transaction tax.
