Mortgage vs Renting Calculator
Lifetime cost of buying vs renting.
Compare the lifetime cost of buying with a mortgage versus renting over any time horizon by entering your monthly payments and years planned.
What this tool does
This calculator models the lifetime cost of buying versus renting by comparing total outflows across your chosen time horizon. It takes your monthly mortgage payment, monthly rent, and the number of years you plan to stay, then shows the cumulative cost of each path side by side. The result illustrates how payment amounts and duration interact to shape total lifetime housing expense. Monthly payment difference is the primary driver of the comparison. A typical scenario might compare a five-year horizon where mortgage and rent differ significantly, revealing which path costs more in pure cash terms over that period. The calculator focuses on direct payments only and does not factor in home equity accumulation, maintenance or repair costs, property taxes, insurance, or rent increases over time. For a more complete picture that includes these elements, a comprehensive rent-versus-buy analysis may be more suitable. This tool is for educational comparison of payment flows.

1,300 monthly mortgage vs 1,500 monthly rent over 25 years: mortgage pays 390,000, rent pays 450,000. On cash alone buying wins by 60,000. Add equity built in the property (often another 100k-200k) and buying produces a lower net cost than renting over long horizons in the inputs tested.
A worked example
Try the defaults: monthly mortgage of 1,300, monthly rent of 1,500, horizon of 25. The tool returns 60,000.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Monthly Mortgage, Monthly Rent, and Horizon. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the option with the lower calculated total changes.
The formula behind this
Cash flow comparison only. Ignores home equity built, maintenance costs, and rent increases. For full comparison use rent-vs-buy calculator with those factors. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Why this matters before you sign
A mortgage is usually the biggest single financial commitment a person makes. The difference between a well-chosen product and a hasty one can run into tens of thousands over the life of the loan. Running the numbers here before committing is the cheapest form of due diligence available.
What this doesn't capture
The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.
Over 25 years, renting at £1,500 monthly costs 60,000.00 compared to a £1,300 monthly mortgage.

Sources & Methodology
Methodology
This calculator computes the cumulative cash flow difference between renting and buying over a specified period. It takes the monthly mortgage payment, subtracts the monthly rent payment, multiplies the result by 12 to annualise, then multiplies by the number of years to produce a total gap. The calculation treats both payments as constant throughout the horizon and expresses the result as an absolute value, indicating which option carries a higher total outlay regardless of direction. The model makes several simplifying assumptions: mortgage and rent payments remain flat, no additional costs such as maintenance, property tax, or insurance are included, and rent does not increase. It does not account for home equity accumulation, property appreciation, transaction costs, or the time value of money. This represents a basic cash flow snapshot only and omits factors material to a full rent-versus-buy decision.
