Rent vs Buy Calculator

The answer depends on your personal circumstances, local property market and time horizon. Buying typically builds equity and protects against rent increases, but comes with high upfront costs, maintenance responsibilities and reduced flexibility. Renting offers flexibility and lower upfront costs but provides no equity. This calculator helps you compare the true financial cost of both options over your chosen time period.

The break-even point is when the total cost of buying becomes cheaper than the total cost of renting over the same period. Before the break-even point, renting is financially better. After it, buying becomes the better financial choice. The break-even point varies enormously by location — in expensive cities it can be 10-15 years, while in more affordable areas it may be 3-5 years.

Buyers face costs renters do not have: mortgage interest, property tax, home insurance, maintenance (typically 1-2% of home value per year), and buying/selling transaction costs (stamp duty, legal fees, estate agent fees — often 3-6% of the property value in the UK). These costs can make buying more expensive in the short term even if monthly mortgage payments are similar to rent.

The opportunity cost is what you could have earned by investing your down payment in the stock market instead of using it as a deposit on a home. For example, a £50,000 deposit invested at 7% annual return would grow to approximately £98,000 after 10 years. This potential gain must be weighed against the equity you build through mortgage repayments and house price appreciation.

If house prices rise faster than the stock market returns you could earn by renting and investing, buying wins financially. If house prices stagnate or fall, renting and investing can be better. UK house prices have historically risen about 4-6% per year on average, though this varies enormously by region and period. Past growth does not guarantee future returns.

Generally, no. The transaction costs of buying and selling (stamp duty, legal fees, estate agent fees) typically total 5-8% of the property value. These costs take several years to recover through equity building and appreciation. Most financial advisers suggest buying only if you plan to stay for at least 5 years, and ideally 7-10 years, to make buying financially worthwhile.
