Rent vs Buy Calculator
Compare the true cost of buying and renting over time, including Stamp Duty, mortgage interest, and what your money could earn elsewhere.
Assumes a standard repayment mortgage, £2,000 in legal and survey fees, 1% of property value per year in maintenance and insurance, and 2% selling costs. This is a planning estimate based on the assumptions you enter, not a guarantee, actual house prices, rents, and investment returns will vary.
Most rent vs buy calculators do a lazy comparison: monthly rent versus monthly mortgage payment, whoever’s lower “wins.” That’s not actually how the maths works. This one factors in Stamp Duty, what your deposit could have earned if you’d invested it instead, and the equity you build over time, then tells you which option genuinely costs less. Below, we walk through exactly how, using current 2026 UK housing data.
What’s the average house price and rent in the UK right now?
The average UK house price was £268,000 in the year to March 2026, essentially flat, according to the Office for National Statistics. Average UK rent was £1,381 a month in April 2026, up 3.5% year on year, a much faster pace than house prices.
| Nation | Average house price | Annual change |
|---|---|---|
| England | £290,000 | -0.6% |
| Wales | £213,000 | +2.9% |
| Scotland | £187,000 | +1.6% |
| Northern Ireland | £198,000 | +7.4% |
The regional split matters more than the national average suggests. London house prices have now fallen for eight straight months in a row, down 2.1% annually as of March 2026, while the East Midlands is leading growth at 0.7%. Rent tells almost the opposite story: London has the highest average rent in the country at £2,290 a month, but the slowest rent growth at just 2.0% annually, while the North East has the cheapest average rent but the fastest growth, at 6.5%.
There’s a technical reason UK house price growth looks unusually slow right now, too. Ahead of the April 2025 Stamp Duty changes (more on those below), a wave of buyers rushed to complete before the deadline, causing prices to spike in March 2025 and drop sharply the following month. ONS refers to this as a “base effect,” and it’s still distorting the annual comparison figures reported through most of 2026.
How does this rent vs buy calculator actually work?
It compares the total net cost of buying against the total net cost of renting over your chosen time horizon, not just monthly payments. Net cost means everything you spend, minus what you get back.
For buying, that’s your deposit, Stamp Duty, legal fees, every mortgage payment, and ongoing maintenance, minus the equity you’d have left if you sold at the end (your home’s value then, minus whatever mortgage you still owe, minus selling costs). For renting, it’s your total rent paid, minus what your deposit and upfront costs would have grown into if you’d invested them instead of spending them on a house purchase. Whichever net figure is lower is the cheaper option under the assumptions you entered.
How much is Stamp Duty when you buy in England?
Stamp Duty Land Tax runs from 0% to 12% depending on the purchase price, and first-time buyers get a partial exemption, but only up to £500,000.
| Price portion | Standard rate | First-time buyer rate |
|---|---|---|
| Up to £125,000 | 0% | 0% |
| £125,000 to £250,000 | 2% | 0% |
| £250,000 to £300,000 | 5% | 0% |
| £300,000 to £500,000 | 5% | 5% |
| £500,000 to £925,000 | 5% | No relief, standard rates apply |
| £925,000 to £1,500,000 | 10% | No relief, standard rates apply |
| Over £1,500,000 | 12% | No relief, standard rates apply |
That £500,000 line is a genuine cliff edge, not a taper. A first-time buyer purchasing at exactly £500,000 pays £10,000 in Stamp Duty. One pound over, at £500,001, they lose the relief entirely and pay standard rates on the whole amount instead, jumping to roughly £15,000. It’s a strange quirk of the system, but it’s real, and it’s exactly why the calculator above checks your price against that threshold precisely rather than rounding.
These specific rates apply in England and Northern Ireland only. Scotland charges Land and Buildings Transaction Tax instead, and Wales charges Land Transaction Tax, both with their own separate bands and their own first-time buyer treatment, so don’t apply this table if you’re buying north of the border or in Wales.
How long do you need to stay for buying to make sense?
There’s no single universal number, but the shorter you plan to stay, the harder it is for buying to beat renting, because Stamp Duty and buying costs get spread over fewer years. Most financial advisers suggest at least four to five years as a rough minimum.
Here’s why. On a £350,000 purchase outside the first-time buyer band, you might pay around £9,500 in Stamp Duty and legal fees combined before you’ve paid a penny of your mortgage down. If you sold after one year, that upfront cost alone could easily outweigh a year’s worth of the equity you’ve built, especially with early mortgage payments weighted mostly toward interest rather than principal. Give it eight or ten years instead, and that same £9,500 gets diluted across a much larger base of built-up equity and, in most markets, house price growth. Try different values for “years you plan to stay” in the calculator above and watch how sharply the verdict can flip.
Why does the calculator count what your deposit could earn elsewhere?
Because a renter doesn’t hand over their deposit and Stamp Duty money to anyone, that cash stays available to invest, and ignoring that overstates how much renting really costs.
Say you’d need a £35,000 deposit plus £9,500 in Stamp Duty and fees to buy, £44,500 total. If you rent instead, that £44,500 doesn’t vanish, it’s sitting in your account or invested. At a modest 5% annual return, over ten years that could grow by roughly £28,000 in gains alone. A rent vs buy comparison that ignores this basically assumes a renter stuffs that cash under a mattress for a decade, which is why so many quick online comparisons make buying look better than it really is relative to a renter who actually invests the difference.
Is buying always better than renting in the long run?
No, and current UK data makes that pretty clear. Rents are rising faster than house prices nationally right now, 3.5% versus roughly flat, but that relationship flips regionally and can flip again within a few years.
London is the clearest example. House prices there have fallen for eight consecutive months, while rents, despite being the highest in the country, are growing at the slowest rate of any English region. A Londoner comparing renting against buying today is working with a very different set of trends than someone doing the same maths in the North East, where rents are climbing 6.5% a year while house prices are still rising too. There’s no version of “buying always wins” or “renting always wins” that holds up against numbers this regionally split, which is exactly why plugging your own real local rent and price assumptions into the calculator matters more than trusting a generic rule of thumb.
How has the age of first-time buyers changed?
The average first-time buyer in the UK is now around 33.9 years old, several years older than a generation ago, and closer to 34.5 in London specifically.
That shift reflects the affordability squeeze more than changing preferences, larger deposits take longer to save relative to income than they used to, and average first-time buyer purchase prices have climbed alongside average earnings growth that hasn’t always kept pace. It’s part of why the rent vs buy decision has become a more active, numbers-driven choice for many people in their late twenties and thirties, rather than an assumption that buying happens automatically once you can technically get a mortgage.
What’s happening in the UK mortgage and housing market in 2026?
Mortgage rates have come down from their 2023 peak, and buyer activity has picked up modestly, but sellers are having to be realistic about asking prices to actually get a sale through.
The Bank of England base rate has fallen to around 3.75% after peaking at 5.25% in 2023, which has fed through into somewhat cheaper mortgage deals than buyers faced a couple of years ago. Mortgage approvals for house purchases came in at 63,531 in March 2026, a reasonably healthy figure by recent standards, suggesting steady rather than booming demand.
What’s more telling is what’s happening to asking prices. Around 53% of sellers who completed a sale in the past three years had to cut their original asking price at some point during the process. Rightmove’s asking-price figures, which sit noticeably higher than the sold-price data from ONS and the Land Registry, reflect that gap between what sellers hope for and what buyers are actually willing to pay. If you’re negotiating on a property, that statistic is worth remembering, the listed price is frequently not the final price.
Rather than guessing, check the ONS regional breakdown for your specific area before entering a house price growth rate, since the gap between London (falling) and the East Midlands (rising) shows how misleading a single national figure can be. For rent growth, local letting agent listings over the past 12 months are more reliable than any national average. For investment returns, a cautious long-term assumption for a diversified portfolio, rather than an optimistic one, gives you a fairer comparison.
It depends heavily on your region and how long you’ll stay. UK rents are rising faster than house prices nationally right now, but London prices are falling while North East rents are climbing fast, so the answer varies a lot by area. Use your own local numbers in the calculator above rather than a national average.
Nothing up to £300,000, then 5% on the portion between £300,000 and £500,000. Above £500,000, the relief disappears entirely and standard rates apply to the full purchase price instead.
£268,000 as of March 2026, according to the ONS and HM Land Registry, with annual growth essentially flat at 0.0%. England’s average is higher at £290,000, though prices there have actually fallen slightly over the past year.
£1,381 a month across the UK as of April 2026, up 3.5% on the year. London is highest at £2,290, the North East lowest, though the North East has the fastest rent growth of any English region.
Because renters keep that cash rather than spending it on a deposit and Stamp Duty, so it’s available to grow elsewhere. Ignoring that overstates how expensive renting really is compared with buying.
Most advisers suggest at least four to five years as a rough minimum, since Stamp Duty and buying costs need time to be outweighed by equity growth. The exact figure depends heavily on your local house price and rent trends.
Around 33.9 years nationally, and roughly 34.5 in London, both several years older than a generation ago as deposits have grown relative to typical incomes.
The mortgage, equity, and investment maths applies UK-wide, but the Stamp Duty calculation is specific to England and Northern Ireland. Scotland uses Land and Buildings Transaction Tax and Wales uses Land Transaction Tax, both with different rates.
