Rent vs Buy Calculator
Use realistic numbers to compare estimated wealth after your chosen time horizon.
How this rent or buy home calculator works
This tool estimates your financial position under two paths: buying a home or continuing to rent. It models mortgage payments, taxes, insurance, maintenance, HOA fees, and transaction costs for buying. For renting, it models rent increases and renter's insurance.
The key comparison is ending wealth. The renter is assumed to invest the money not used on a down payment and closing costs, plus any monthly savings if renting is cheaper than owning. Meanwhile, the buyer builds equity through principal paydown and home appreciation.
Inputs that matter most
1) Time horizon
Time in the home is usually the most important variable. Buying tends to look worse over short periods because closing costs and selling costs are front-loaded. The longer you stay, the more time you have to recover those costs.
2) Mortgage rate and home price
Higher rates increase your monthly payment and reduce how quickly equity grows from principal repayment. A lower rate can significantly shift the result in favor of buying.
3) Rent growth and home appreciation
If rent is rising quickly, buying can become more attractive over time. If home appreciation is slow (or negative), renting may win even over longer periods.

Because life is messy, use this as a planning framework, not a perfect forecast.
How to use this calculator responsibly
Run multiple scenarios
Don't trust a single estimate. Try a conservative case, a likely case, and an optimistic case for both home appreciation and investment returns.
Stress test your budget
Even if buying wins on paper, make sure the monthly payment leaves room for emergencies, retirement savings, and lifestyle goals.
Account for career and family plans
If you may move in 2–4 years, renting often provides lower risk. If you plan to stay put for 7+ years, buying often becomes more competitive.
Bottom line
"Rent vs buy" is not a universal answer. It's a math problem plus a lifestyle decision. Use this calculator to understand the math clearly, then combine it with your flexibility needs, job stability, and personal goals.
