The decision to rent or buy a home is one of the most consequential financial choices you will ever make. Conventional wisdom often claims that "renting is throwing money away," but purchasing a home involves massive unrecoverable "sunk costs"—including mortgage interest, property taxes, maintenance, HOA fees, and closing costs. A Rent vs. Buy calculator runs a comparative amortization and equity growth simulation to determine your "breakeven horizon"—the exact number of years it takes for buying to become mathematically cheaper than renting.
The 5% Rule of Thumb
As a quick baseline, calculate the "unrecoverable" costs of a home (Property Tax + Maintenance + Cost of Equity = ~5% of the home's value annually). If your annual rent is less than 5% of the target home's purchase price, renting is often financially advantageous.
How to Use This Calculator
- Enter the target purchase price of the home and the expected mortgage interest rate.
- Input your current (or expected) monthly rent for a comparable property.
- Specify the expected annual property appreciation rate and the annual rent increase rate.
- Click Calculate to generate a side-by-side comparison of net wealth accumulation and find your breakeven year.
Frequently Asked Questions (FAQ)
Why is renting sometimes better than buying?
Renting provides extreme liquidity and protects you from sudden maintenance disasters (like a $10,000 roof replacement). If you invest the down payment money you saved by renting into a diversified stock market index fund, your liquid wealth may outpace the equity built in a heavily financed home over a 5 to 10-year period.
How do closing costs affect the breakeven point?
Closing costs (broker fees, appraisals, title insurance) typically amount to 2% to 5% of the home's purchase price. When you eventually sell the home, agent commissions will cost another 5% to 6%. Because these transaction costs are so steep, buying is almost always a financial loss if you plan to move within 3 to 5 years.
