Details
The calculator subtracts estimated equity after sale from down payment, closing costs, and monthly ownership costs.
Rent is summed month by month and increases once per year by the rent growth rate entered.
A positive difference means buying costs more in the scenario. A negative difference means buying costs less in the scenario.
Short stays can make transaction costs matter more. Long stays can make appreciation, maintenance, and rate assumptions matter more.
After the comparison, use the mortgage calculator, mortgage affordability calculator, debt-to-income calculator, or rent affordability calculator to test the specific budget path.

Benchmarks
A broad planning heuristic: small differences can be overwhelmed by repairs, rent changes, taxes, or market moves.
Closing and selling costs can dominate if you expect to move soon.
Appreciation, rent growth, maintenance, rate, and tax assumptions get more important over time.

FAQ
Compare the rent paid over the same period with the owner's out-of-pocket cost after subtracting estimated equity at sale.
No. It focuses on direct housing cash flows and estimated equity. If down payment or closing cash would be invested elsewhere, compare that opportunity cost separately before treating the result as final.
No. It is a planning comparison. Taxes, repairs, PMI, insurance, local market prices, lifestyle needs, and lender terms can change the decision.
Buying has transaction costs. A longer holding period spreads those costs across more months, while a shorter stay gives less time for equity to build.
Holding period, home appreciation, rent growth, mortgage rate, maintenance cost, and transaction costs usually move the comparison the most.
Yes. Down payment and closing cash could have been saved or invested elsewhere, so opportunity cost helps compare buying with renting more fairly.
