The interactive calculator is temporarily unavailable. Please use the comprehensive analysis, worked examples, and regional data provided below to evaluate your rent vs buy decision.
For immediate guidance, review the worked UK 2026 average scenario below which shows buying typically wins after ~6 years.
How to read your result
The calculator compares two scenarios over your chosen time horizon:
Buying scenario: You buy the property with your deposit, pay the mortgage, maintenance, and SDLT, then sell at the end. Your "net wealth" is the sale proceeds minus any remaining mortgage and selling costs.
Renting scenario: You rent the property and invest your saved deposit plus the monthly difference between mortgage payments and rent. Your "net wealth" is your investment portfolio value.
The "break-even year" shows when the buyer first comes out ahead. If it's year 6, buying wins from year 6 onwards but renting wins in years 1-5.
Key insight: Most people focus on monthly costs (mortgage vs rent), but the real question is total wealth after your time horizon. A £200/month higher mortgage might still win if house prices grow faster than your investment returns.
How does this play out across the UK?
Using ONS April 2026 data and the calculator's default mortgage rate (5.67% 5-year fix) at 10% deposit.
The UK average obscures very different regional pictures. Where rents are higher than mortgages (London, South East), break-even comes faster. Where house prices are growing fastest (Northern Ireland, North East), buyer equity builds faster.
| Region | Avg house price | Avg monthly rent | YoY rent growth | Break-even (years) |
|---|---|---|---|---|
| London | £525,000 | £2,400 | +1.7% | ~5 |

The Lifetime ISA — should it shape your decision?
If you're a first-time buyer under 40, the Lifetime ISA (LISA) is one of the largest single financial wins available. You can save up to £4,000 a year, the government adds a 25% bonus on top (max £1,000/year), and you can use the lot — plus any growth — to buy a first home up to £450,000.
A few key rules:
- Eligible age: open between 18–39, contribute until 50, but you can withdraw the bonus from age 60 for retirement
- Property cap: £450,000 anywhere in the UK
- Penalty: 25% withdrawal penalty if used for anything other than a qualifying property purchase or retirement after 60 — this means you can actually get back less than you paid in, so the LISA only makes sense if you're committed to the qualifying use
- Couples advantage: if two first-time buyers buy together, both can use a LISA on the same property — that's £2,000/year in government bonuses, effectively
April 2028 change: the Lifetime ISA will be replaced by a new first-time buyer ISA from April 2028. The good news for existing holders: you can keep contributing to your current LISA indefinitely, so opening one now is still a sound move if you plan to buy within the next few years.
Where this fits in the calculator: if you have a partner LISA available, you have £2,000/year of free money the rent-and-invest scenario doesn't get. Factor this into the "investment return" assumption — for a couple with two LISAs each contributing £4,000/year for 5 years, that's £10,000 in bonuses on top of any market return. Few competing calculators surface this; we should.

Where are mortgage rates right now?
Mortgage pricing in May 2026 sits significantly higher than its early-2026 lows. Average rates dropped through 2025, with the average 2-year fix falling from 5.48% in January 2025 to 4.83% by January 2026. Then geopolitical events in the first quarter of 2026 — the energy shock from the conflict in the Middle East — pushed swap rates sharply higher in March, and lenders followed. Moneyfacts data shows the average 2-year fix moving from 4.84% on 6 March to 5.58% by 26 March, in a window where the Bank of England base rate did not move.
As of 15 May 2026 (Moneyfacts):
- 2-year fix average: 5.75%
- 5-year fix average: 5.67%
- Standard variable rate (avg): ~7.13%
- Best 2-year fix at 60% LTV: HSBC at 4.45% (£999 fee), per HomeOwners Alliance, 17 May 2026
- Bank of England base rate: 3.75%, held on 30 April 2026 (third consecutive hold, 8-1 vote with one member preferring a hike)
What this means for the calculator: the default rate of 5.67% reflects the May 2026 market for a typical 5-year fix. Your actual rate will depend on your LTV, credit profile, and any fee-bearing deals. If you're at 60% LTV you can do considerably better — the 4.45% HSBC deal cited above is around 122 basis points below the average, which on a £241,200 mortgage is roughly £170/month lower. Always compare with a fee-free broker before locking.
Approximately 1.8 million fixed-rate mortgages are due to come off fix in 2026 (UK Finance). If you're remortgaging, a rate-watch service (free from most brokers) will let you lock now and switch if rates fall before completion.
The true costs of buying — extended
Upfront costs:
- Deposit: 5–20% of property value (average 15% for first-time buyers)
- SDLT/LBTT/LTT: varies by region and property value — use our Mortgage Calculator for exact SDLT calculations
- Legal fees: £1,000–£1,500 for conveyancing
- Survey: £400–£1,500 depending on type (HomeBuyer vs Building Survey)
- Mortgage arrangement fee: £0–£2,000 (can often be rolled into the mortgage)
- Valuation: usually free with mortgage application
Ongoing costs:
- Maintenance: £7,530/year average (Checkatrade 2025 research) — 1% vs 3% debate settled by real data
- Buildings insurance: £200–£600/year depending on property type and location
- Service charges (leasehold): £1,000–£5,000/year for flats
- Ground rent: banned for new leases from June 2022 under the Leasehold Reform (Ground Rent) Act 2022
Less obvious costs:
- Council tax band changes: if you extend or improve, the Valuation Office Agency may reassess your band upwards
- Early repayment charges: if you overpay beyond your annual allowance (typically 10%)
- Leasehold service charge inflation: often rises faster than general inflation
- Major works contributions: leaseholders can be hit with sudden bills for roof repairs, lift replacement etc.
The renter costs nobody talks about
Renting in the UK comes with structural costs that are easy to forget:
- Tenancy deposit: capped at 5 weeks' rent under the Tenant Fees Act 2019 (6 weeks if annual rent > £50,000). On the UK average rent of £1,377/month, that's £1,589 you'll typically be unable to invest while it's held — though it must be lodged in a government-approved deposit protection scheme.
- Holding deposit: capped at 1 week's rent, generally refundable if your tenancy proceeds.
- Rent in advance: most landlords require the first month's rent on move-in. So at the average UK rent, your initial cash outlay is around £2,966 (deposit + 1 month) before you've lived anywhere.
- Tenancy renewals and references: under the Tenant Fees Act, landlords can no longer charge for renewals, references, inventories, or check-out. This is a meaningful saving versus the pre-2019 regime.
- Section 21 risk: under the current law (about to change — see below), private tenants can be evicted with two months' notice for no reason. This carries real economic cost — moving fees, deposits in transit, time off work.
The big change coming — the Renters' Rights Bill 2024-25: expected to receive Royal Assent in 2025, this abolishes Section 21 no-fault evictions, converts all assured shorthold tenancies to periodic tenancies, and limits rent increases to once a year at market rate (challengeable at tribunal). It materially shifts the security-of-tenure picture in favour of renters — by the time most readers of this calculator make a multi-year decision, that protection will be in place.
