House price growth calculator
What compound growth does to a price over 5, 10 or 25 years.
This is the national average trajectory — local markets differ hugely, and individual homes more still. For a real answer, check actual sold prices for the address and street on our sold-price explorer. Illustration only, not a valuation.
House price growth compounds, which is why small annual differences become enormous over a mortgage term: £250,000 growing at 3% a year reaches about £336,000 in 10 years and £523,000 in 25; at 5% those figures are £407,000 and £847,000. The calculator does the compounding; the judgement — what rate to assume — is yours, and it deserves honesty.
The honest context: UK prices have grown strongly over the long run in cash terms, but the growth is lumpy and local. Whole decades have gone sideways or backwards in real terms (the 1990s after the 1989 crash; much of the 2010s outside the South East; 2022–24 in real terms nationally), and regional gaps are persistent — the same decade can double prices in one city and barely move them in another. Past growth in a postcode is evidence, not a promise.
Two disciplines make projections useful rather than comforting. Test a range, not a point: run 0%, 2.5% and 5% and make sure the purchase makes sense across all three — if the plan only works at 5%, it is a bet, not a plan. And think in real terms: 3% growth with 3% inflation is a home holding its value, not making you money. Nominal growth pays off the mortgage in shrinking pounds either way, which is a genuine, underrated benefit of owning — but it is a different claim from “prices always go up”.
Common questions
What is the average UK house price growth per year?
Over the long run, UK prices have averaged mid-single digits annually in cash terms — but with huge variation by decade and region, and much less impressive after inflation. Planning with a range of 0–5% nominal is more honest than any single number; the calculator makes comparing scenarios easy.
How much will a £250,000 house be worth in 10 years?
At 2% a year, about £305,000; at 3%, £336,000; at 5%, £407,000; at 0%, still £250,000 — all in cash terms, before inflation. The point of the spread is that a 10-year projection is a scenario, not a forecast: sensible decisions survive the low end.
Does house price growth matter if I’m not selling?
Yes, three ways: it moves your loan-to-value, unlocking cheaper remortgage bands; it builds equity you can borrow against or take to the next home; and in a downturn it determines whether you can move at all (negative equity traps people). But your home’s growth is also matched by the next home’s — trading up in a rising market costs more, not less.
Should I count house price growth when deciding to buy?
Count it as upside, not as the case for buying. Buying stacks up when you can afford the true monthly cost, plan to stay long enough to beat the transaction costs (typically 3–5 years), and the numbers work at 0% growth. If the sums need 5% a year to work, rent-vs-buy is the calculator to run next.
