Key takeaways
- UK mortgage holders paid £224.40 a week on their mortgage in 2024-25. Only £122.10 of that built equity. The other £102.30 was interest and protection premiums.
- That makes 45.6% of the average mortgage payment as unrecoverable as rent. Renters paid £191.70 a week in gross rent over the same year.
- Add upkeep and buildings insurance and the owner's unrecoverable cost reaches about £125.32 a week, or 65.4% of what the average renter paid.
- On the average £272,000 home at June 2026 rates, year-one unrecoverable cost comes to £13,443 against £16,716 of average UK rent.
- UK house prices grew 1.19% a year above RPI between 1987 and 2026. Leverage, not the absence of dead money, is what magnifies that.
Rent is dead money, and so is 45.6% of the average mortgage payment
The phrase gets used as though it settles the argument. You hand a landlord £1,393 a month and you own nothing at the end of it, while your neighbour hands a bank the same amount and owns a house. Put like that, renting looks indefensible.
The arithmetic doesn't support the strong version of the claim. In the financial year ending 2025, the average UK household with a mortgage paid £224.40 a week towards it. Of that, £122.10 was capital repayment, which does convert into equity. The remaining £102.30 was mortgage interest of £99.10 plus £3.20 of mortgage protection premiums. That money leaves the household and doesn't come back, in exactly the way rent doesn't come back.
So the honest framing isn't £192 of dead money against zero. It's £191.70 a week of gross rent against £102.30 a week of interest, before the owner has paid for a single roof tile. The owner's dead money is 53.4% the size of the renter's. That's a real gap and it's worth having. It just isn't the gap the phrase implies.
What UK households actually paid in 2024-25
These aren't modelled figures. They come from the Office for National Statistics Living Costs and Food Survey, published as Family Spending workbook 5, covering April 2024 to March 2025. The survey weighted its results to 8,650 thousand mortgage-holding households and 10,000 thousand renting households, out of 28,710 thousand households in total.
The renter side is simple. Gross rent averaged £191.70 a week. After housing benefit and rebates, net rent was £165.60. Nothing in that payment accrues to the tenant.
The mortgage side splits three ways, and the split is the whole argument. Capital repayment at £122.10 a week is 54.4% of the payment, and it's a transfer from the household's cash into the household's balance sheet. Mortgage interest at £99.10 is a payment for the use of someone else's capital. Protection premiums at £3.20 buy insurance. Neither of the last two comes back.
Here's the part that gets skipped. Both figures are averages over very different populations. Mortgage holders had 2.8 people per household against 2.4 for renters, and total weekly expenditure of £1,488.50 against £748.20 for renters. They spend more in total, and on more people. The comparison below holds the property constant instead, which is the fairer version.
The costs that land only on the owner
The renter's payment is the whole of the renter's housing cost. The owner's isn't. Three categories sit outside the mortgage entirely, and the same ONS survey measures them.
- Maintenance and repair of the dwelling: £11.90 a week, averaged across all households.
- Structure insurance: £3.10 a week, again across all households.
- Moving house, meaning property transaction costs: £1.90 a week.
Those are all-household averages, which understates them for owners. Maintenance and structure insurance come to £15.00 a week between them. Push all of it onto the roughly 18,710 thousand households that aren't renting and it becomes £23.02 a week. That assumes renters bear none of it, which makes £23.02 an upper bound rather than a measurement.
That takes the owner's unrecoverable weekly cost to £125.32 against the renter's £191.70. The owner is still ahead, by 34.6 percentage points of rent, or about £3,452 a year. The claim survives. It survives much smaller than advertised.
One line in the ONS table deserves separating out. Alterations and improvements to the dwelling ran at £32.00 a week, more than twice the maintenance figure. That spending is discretionary and it partly converts into value, so counting it as dead money would overstate the case against owning. Counting none of it understates the cash a house absorbs.
The average UK home at June 2026 prices and rates
Population averages mix a 1990s mortgage with one taken out last month. A cleaner test is to price the transaction as it stands today. The ONS put the average UK house price at £272,000 in June 2026, and average UK monthly private rent at £1,393 in July 2026.
Take a 20% deposit, which is an assumption rather than a measured average. That's £54,400 down and a £217,600 mortgage. The Bank of England reported the effective interest rate on newly drawn mortgages at 4.35% in June 2026. Interest on the opening balance at that rate is £9,466 for the first year.
Stamp duty comes next. Under the bands in force from 1 April 2025, the nil-rate threshold is £125,000, the portion to £250,000 is taxed at 2% and the portion above at 5%. On £272,000 that's £3,600 for a buyer who isn't a first-timer. Between 31 October 2024 and 31 March 2025 the nil-rate band sat at £250,000, so the same purchase cost £1,100 and the threshold change added £2,500. First-time buyers pay nothing up to £300,000, so on this house their stamp duty is zero.
HM Land Registry charges £330 by post to register a transfer in the £200,001 to £500,000 band, under fees that came into effect on 9 December 2024. The English Housing Survey found that in 2024-25, owner occupiers buying with a mortgage had lived in their home for an average of 8.9 years. Spread the £3,600 and the £330 over that, and transaction tax and registration cost £442 a year.
Then the deposit. £54,400 sitting in a house isn't sitting anywhere else. The Bank of England put the effective rate on individuals' new time deposits at 4.30% in June 2026, so the forgone interest is £2,339 a year. That's a conservative benchmark, because it's a cash rate rather than an equity one.
Add it up: £9,466 of interest, £1,197 of maintenance and structure insurance, £442 of amortised transaction cost and £2,339 of forgone deposit yield. Year-one unrecoverable cost is £13,443. Renting the average UK home costs £16,716 a year. The owner is 80.4% of the way to the renter's bill before a single brick has appreciated.
First-time buyers are running different arithmetic
One line of the calculation moves a long way depending on who's buying. A first-time buyer pays no stamp duty up to £300,000, so on a £272,000 house their bill is zero rather than £3,600. That drops the amortised transaction cost from £442 a year to about £37, and takes year-one unrecoverable cost from £13,443 to £13,039.
The relief is also a threshold, not a taper across the whole price range. It stops applying above £500,000, at which point a first-time buyer pays the standard rates on the entire purchase price. The same house, bought by the same person, can carry a stamp duty bill that changes by thousands on either side of a line.
The strongest case for owning isn't that rent is dead money
Someone who has read this far and still owns their home is not being told they got it wrong. The case for buying is real, and it doesn't rest on the dead-money framing at all. It rests on leverage.
Nationwide's index, which runs back to 1952, puts the UK all-houses price at £42,986.84 in Q2 1987 and £278,784 in Q2 2026. That's 4.91% a year nominal. Over the same window the ONS Retail Prices Index went from 101.9 in June 1987 to 416.5 in June 2026. Net of that, UK house prices gained 1.19% a year in real terms across 39 years.
On a £272,000 house, 1.19% is £3,237 a year. That alone cuts the owner's £13,443 to £10,206 against £16,716 of rent. But the buyer put down £54,400, not £272,000. The gain lands on the whole asset while the capital at risk is a fifth of it, so a 1.19% real return on the house is close to 6.0% on the deposit. That is the argument, and it's a good one.
Leverage runs in both directions, which is where the critics of the dead-money case have their best evidence. Nationwide's series shows the UK average falling from £184,130.88 in Q3 2007 to £149,709.13 in Q1 2009, a drop of 18.7%. On a 20% deposit, that move erases 93.5% of the buyer's equity. The renter's downside over the same stretch was that they paid rent.
Where this comparison breaks
Four limits, and none of them is small.
The average rented home and the average owned home are not the same home. The ONS rent figure and the ONS house price figure are drawn from different stocks, and nothing in either series makes them the same property. Setting £16,716 of rent against a £272,000 purchase compares two things that only roughly correspond.
The national figure hides a spread that dwarfs every cost above. Average rent in July 2026 was £2,317 a month in London and £783 in the North East, a ratio of 2.96 to 1. Every figure in this piece is a UK average, so the rent-versus-buy answer in one region says almost nothing about the other.
The maintenance figure is a survey average and it's lumpy. A household that spent nothing for six years and then several thousand pounds on a roof shows up in the same mean as one that spent a few hundred a year forever. Averages hide the timing, and timing is what forces a sale.
The comparison also assumes the renter does something with the deposit. Charging the owner £2,339 of forgone interest only makes sense if the renter's £54,400 is actually earning it. A renter who spends the difference has none of the owner's dead money and none of the owner's equity either, and the arithmetic above says nothing useful about them. Every rent-versus-buy calculation ever published carries that assumption, and most don't state it.
Finally, 39 years of real house price growth is one sample from one country. It also starts just before a boom: the index ran from £42,986.84 in Q2 1987 to a peak of £62,781.67 in Q3 1989, a rise of 46.0% in nine quarters, and then didn't exceed that peak in nominal terms until Q1 1998 at £62,903. A start date one boom earlier or later moves the 1.19% figure, and a backtest is not a forecast.
The claim, and what the evidence says about it
Claim: rent is dead money.
Evidence: in 2024-25 the average UK mortgage payment was £224.40 a week, of which £102.30 was interest and premiums that don't come back. Adding upkeep and insurance takes the owner's unrecoverable cost to about £125.32 a week against £191.70 of gross rent. On the average home at June 2026 prices, year-one unrecoverable cost is £13,443 against £16,716 of rent.
Verdict: partly true, and directionally right. Renting is entirely dead money and owning is roughly 65.4% dead money on the population figures, or 80.4% on a purchase made today. The phrase describes a difference of degree and is usually deployed as a difference of kind.
For anyone tracking a house alongside everything else they own, the same distinction matters at the portfolio level: the interest and upkeep are running costs, and only the capital repayment and the price change belong on a net worth line. LedgerTouch treats residential property that way.
What would change this
The mortgage rate is the hinge. At 4.35% on £217,600, interest is £9,466 and it dominates every other unrecoverable cost put together. Halve the rate and interest falls to £4,733, taking the owner's total to £8,710, or 52.1% of the renter's bill. The fixed vs variable mortgage decision moves this number more than anything else on the list.
The holding period is the second hinge. At 8.9 years the £3,930 of stamp duty and registration costs £442 a year. At three years it costs £1,310, and at 20 years it's £197. Private renters moved every 4.7 years on average in 2024-25, and owner occupiers as a whole stayed 17.0 years. For anyone whose own horizon sits closer to the renter's, the amortisation runs on a different number.
The third is the deposit's alternative. At the 4.30% cash rate the opportunity cost is £2,339 a year, and cash is the least demanding comparison available. Measured against an equity return the deposit's drag is larger, and the case for a mortgage overpayment vs investing comparison runs on the same logic. Whether housing beats shares over a long horizon is a separate question from whether renting is dead money, and it's dealt with under house as an investment.
What wouldn't change it is the phrase itself. Every payment above was measured. If the response to £102.30 a week of interest is that it still isn't rent, that's a preference rather than an argument, and preferences are allowed. They just aren't arithmetic.
