Renting versus buying: what nobody adds up
Somebody will tell you that rent is dead money. Somebody else will tell you that a mortgage is a thirty year sentence. Both of them are selling you a feeling rather than a sum. This page does the arithmetic in both directions and shows you the parts that get quietly left out of each side, because the parts left out are where the real difference lives.
Renting and buying cost far more alike than either side admits. In England the average weekly private rent is £250 and the average weekly mortgage payment is £242. The difference is not the payment. It is who carries the risk, who can leave, and how much of your money disappears as interest and fees rather than as rent.
The claim: rent is dead money
The argument is simple. Rent goes to a landlord and you never see it again. A mortgage payment builds up something you own. Therefore renting wastes money and buying does not.
The first half is true. The second half is only partly true, and the missing part is large enough to change the answer.
A repayment mortgage payment is two things stuck together: a bit that reduces what you owe, and a bit that is pure interest. The interest is money you never see again, exactly like rent. And at the start, almost all of it is interest.
Read the top bar again. In the first month of that mortgage, £790 out of £1,082 is rent. It is rent paid to a bank instead of a landlord, for the use of money instead of the use of a building, but nobody is getting it back. Over the full twenty five years the interest adds up to roughly £144,000 on top of the £180,800 borrowed.
So the honest version of the claim is not "rent is dead money and mortgages are not". It is: both cost you money you never see again, and the mortgage also builds up an asset while the rent does not. That is still a real advantage. It is just a much smaller one than the slogan suggests, especially in the early years, which are exactly the years most people your age would be in.
The two numbers people quote at each other
The English Housing Survey for 2024 to 2025 measured what households actually pay. Private renters spend 34% of their household income on rent. People buying with a mortgage spend 19% of theirs on the mortgage. That looks like a knockout blow for buying.
Now look at the weekly amounts from the same survey. Average private rent: £250 a week. Average mortgage payment: £242 a week. Nearly identical.
Both facts are true at once, and the reason is the thing worth understanding. Those are not the same people. To get a mortgage you had to have a deposit and pass an affordability check, which quietly selects for people who already earn more. The 34% and the 19% are not two futures available to one person. They are two different groups of people. Anybody who shows you those percentages as proof that buying is cheaper is skipping that step, and it is the step that does all the work.
Every comparison you will be shown compares rent against a mortgage payment. Neither side is the real number.
Buying, before you own anything: conveyancing and searches up to about £1,800, a survey between £400 and £1,500 depending on how much you want to know, a mortgage arrangement fee up to about £1,500, a valuation fee up to £300, and removals from about £450. Stamp duty is £0 for a first time buyer up to £300,000 in England and Northern Ireland, which is the one real break in the list, and it disappears entirely above £500,000.
Buying, every year afterwards: buildings insurance, council tax, and every repair. When the boiler dies it is yours. If the flat is leasehold there is a service charge and possibly ground rent, and you do not set either.
Renting, the part that is understated: the price is not fixed. UK private rents rose 3.7% in the year to July 2026 and the average is now £1,393 a month. A mortgage payment on a fixed rate does not move for the length of the fix. Rent moves with the market for as long as you rent, which could be your whole life.
What this does and does not prove
It does not prove that buying is better, and it does not prove that renting is. It proves that the monthly payments are closer than the argument suggests, that a large slice of a mortgage payment is as dead as rent, and that the extra costs sit almost entirely on the buying side while the price risk sits almost entirely on the renting side.
What it leaves open is the part nobody can calculate for you. House prices can fall. Rents can rise. You might need to move cities for work at twenty six, and a renter does that in a month while an owner does it over four months and several thousand pounds. You might want a dog and a wall you are allowed to paint. Those are not maths. They are the actual question, and they are yours.
- Split the payment. On any mortgage you are shown, ask how much of the first year's payments is interest. If nobody volunteers it, put the loan, rate and term into a calculator yourself. It takes a minute.
- Add the entry costs to the deposit. The deposit is not the amount you need. The deposit plus fees plus survey plus moving is the amount you need, and it is usually a few thousand more.
- Price the repairs. A rough rule people use is one percent of the property's value a year for maintenance. On a £226,000 flat that is about £2,260 a year that a renter does not pay.
- Check leasehold before anything else. Service charge and ground rent are real monthly costs that no comparison ever includes, and on some flats they are the size of a second bill.
- Ask how long you are staying. The entry costs are paid once and only make sense spread over years. The shorter the stay, the worse buying looks, and it has nothing to do with dead money.
- Compare like with like. Rent versus mortgage payment is not a comparison. Rent versus mortgage payment plus insurance plus repairs plus service charge, against the interest you would not be paying, is.
None of this tells you which to do. It tells you what the two things actually cost, which is the only ground worth arguing from.
- The income shares and the weekly amounts. English Housing Survey 2024 to 2025, housing costs and affordability: private renters 34% of household income, mortgagors 19%; mean private rent £250 a week, mean mortgage £242 a week. England only.
- The rent figures. ONS private rent and house prices, August 2026 bulletin: UK average private rent £1,393 a month in July 2026, up 3.7% over the year. Average UK house price £272,000 in June 2026.
- The mortgage rate. Uswitch average UK mortgage rates, checked 26 August 2026: average two year fix at 75% loan to value 5.24%. Bank of England Bank Rate held at 3.75% on 30 July 2026.
- The buying costs. HomeOwners Alliance, the costs of buying a house, updated 28 July 2026: legal work up to £1,800, surveys £300 to £1,500, arrangement fees £500 to £1,500, valuation up to £300, removals £450 to £1,400.
- The stamp duty thresholds. GOV.UK stamp duty residential rates: first time buyers pay nothing up to £300,000, 5% from £300,001 to £500,000, and get no relief at all above £500,000. England and Northern Ireland.
- Our arithmetic. £180,800 borrowed over 300 months at 5.24% a year gives a payment of £1,082.37. Month one interest is £180,800 × 0.0524 ÷ 12 = £789.49. Total paid is £324,712, so total interest is £143,912. Every step reproducible.
Questions people ask
Is renting really throwing money away?
Rent buys you somewhere to live and you do not get it back. That much is true. The part usually left out is that mortgage interest works the same way, and in the early years of a mortgage most of the payment is interest. On a typical first mortgage the interest alone can come to well over a hundred thousand pounds across the term. Buying builds an asset, which renting does not, but the gap is far narrower than the slogan.
Is it cheaper to rent or to buy in the UK right now?
On the monthly payment alone they are close: the English Housing Survey puts mean private rent at £250 a week and mean mortgage payments at £242 a week. Once you add buying costs, insurance, repairs and any service charge, buying costs more month to month and builds equity while doing it. Which comes out ahead depends on how long you stay and what happens to prices, neither of which anyone knows in advance.
How much of my mortgage payment goes on interest?
At the start, most of it. On £180,800 over 25 years at 5.24%, the first payment is about £1,082 and about £790 of that is interest. By the last year the same payment is about £55 interest and about £1,027 off the debt. That is how amortisation works: interest is charged on what you still owe, so it shrinks only as the debt does.
What costs do people forget when buying a house?
Conveyancing and searches, a survey, a mortgage arrangement fee, a valuation fee, removals, buildings insurance, and every repair from then on. On a leasehold flat, service charge and ground rent as well. Together the one off costs commonly run to a few thousand pounds on top of the deposit, before a single mortgage payment is made.
Do rents go up more than mortgage payments?
Rents track the market: UK private rents rose 3.7% in the year to July 2026. A fixed rate mortgage payment does not move at all until the fix ends, at which point it can move sharply in either direction. So renting has steady small risk and fixed rate borrowing has occasional large risk. Neither is the safe option; they are different shapes of risk.
Should I buy as soon as I can afford to?
This site does not tell anybody what to do with their money. The questions that actually decide it are how long you expect to stay in one place, whether the entry costs have time to be worth it, and whether you could cover the payment if the rate at the end of your fix were higher. Those are answerable. "Is it a good time to buy" is not.
