Rent vs Buy Calculator UK 2026 — Is Buying Worth It?
The rent vs buy decision is more complex than it first appears. Buying builds equity but the upfront costs are significant — stamp duty, solicitor fees, survey, and a deposit that could otherwise be invested. The key metrics: opportunity cost of the deposit, total ownership costs (mortgage, maintenance ~1%/year, transaction costs), and rent savings as equity builds.
In most UK locations, buying beats renting financially if you stay 5+ years. In high-cost cities the breakeven can stretch to 10+ years.

Rent vs Buy Calculator: Which Costs Less in the Long Run?
Deciding whether to rent or buy a home is one of the biggest financial decisions you will make. This calculator compares the total costs of both options over a time period you choose, factoring in rent increases, mortgage interest, maintenance, stamp duty, and potential house price growth.
The true cost of buying
Beyond the mortgage payment, homeowners face significant additional costs. Upfront costs include stamp duty (potentially thousands), solicitor fees (£800-£1,500), survey costs (£250-£600), and mortgage arrangement fees (£0-£1,500). Ongoing costs include building maintenance (budget 1% of property value per year), buildings insurance (£200-£400/year), ground rent and service charges (for leasehold), and eventual selling costs (estate agent fees of 1-2%).
However, buying also builds equity — as you pay down your mortgage, you own more of your home. If house prices rise, your equity grows further. Over 10-20 years, this equity accumulation can significantly outweigh the extra costs of owning versus renting.
When renting makes more sense
Renting offers flexibility — you can move easily for work or personal reasons without the cost and hassle of selling. You avoid maintenance responsibilities, large upfront costs, and the risk of falling house prices. In areas where house prices are very high relative to rents, renting and investing the difference elsewhere can yield better returns.
Generally, buying becomes financially advantageous if you plan to stay in the same property for at least 5-7 years. Before that, the upfront costs of buying often exceed any equity you build. Use this calculator with different time horizons to see what works for your situation.
How This Calculator Works
This calculator compares the total net wealth of two scenarios over time:
- Buying: You pay a deposit, take a mortgage, cover maintenance/insurance, and build equity as the property (hopefully) appreciates. When you sell, you pay estate agent fees and legal costs.
- Renting: You pay rent monthly, don't build property equity, but you keep your deposit and buying costs invested elsewhere. That investment pot grows at your assumed return rate.
The breakeven year is when the net wealth from buying first exceeds the net wealth from renting. Before that point, renting may be financially superior. After that point, buying typically wins — assuming house prices rise.
Stamp Duty Rates for First-Time Buyers (2026/27)

When Does Buying Win?
Buying typically becomes the better financial choice when:
- You plan to stay in the property for 5-8+ years
- House prices rise at 2-3%+ annually
- Mortgage rates are below house price growth
- You have a sizeable deposit (reduces interest paid)
- You can comfortably afford maintenance and repairs
Buying wins faster when house prices rise quickly, mortgage rates are low, and your deposit is large. It wins slower (or never) when prices stagnate, rates are high, or you move frequently.
When Does Renting Win?
Renting can be the smarter financial move when:
- You need flexibility to move for work or relationships
- You live in an area where house prices are flat or falling
- You can earn high investment returns (7%+) on your deposit money
- You'd struggle with unexpected repair bills (£5k boiler, £15k roof)
- You plan to move within 3-4 years (selling costs eat your equity)
- You're in a high-yield rental market where rent is cheap vs prices

What You Should Do Next
- Compare over your intended stay — The breakeven point is typically 5-7 years. If you might move sooner, renting often wins financially.
- Factor in maintenance costs — Homeowners spend ~1% of property value annually on maintenance. Our calculator includes this, but budget separately for major repairs.
- Consider your mortgage options — Fixed-rate mortgages provide certainty; trackers may be cheaper but carry rate-rise risk. Shop around and consider a broker.
- Don't forget opportunity cost — Money used for a deposit could be invested elsewhere. Our calculator compares property equity growth vs. alternative investments.
