Rent Vs. Buy Calculator
Buying wins in the long run, renting wins short-term — but where is the crossover? This calculator simulates 30 years of owning (payments, taxes, insurance, maintenance, appreciation, selling costs) against renting (rent with increases, insurance, deposit) and reports exactly how long you need to stay for buying to pay off.

Pro tips
- • If you may move within 3–5 years, renting usually wins — closing costs eat equity that fast.
- • Rent increases compound: locked principal-and-interest payments are buying’s quiet advantage.
- • Break-even moves earlier with a bigger down payment, lower rates, or higher expected appreciation.
