What Is a Rent vs Buy Calculator?
A rent vs buy calculator compares the financial outcome of renting a home versus purchasing one. It uses the price-to-rent ratio and estimated monthly buy costs (mortgage, tax, and insurance) to help you decide which option may be better for your situation.
How to Use This Rent vs Buy Calculator
- Enter your current monthly rent.
- Enter the home purchase price and the mortgage interest rate (as a percentage).
- Click “Calculate” to see the verdict (rent or buy), the price-to-rent ratio, and an estimated monthly buy cost compared to your rent.
Key Concepts
The buy scenario includes mortgage payments, property taxes, insurance, maintenance (1%–2% of home value annually), and closing costs, offset by equity buildup and home appreciation. The rent scenario is simpler but must account for annual rent increases (typically 3%–5%) and the potential investment returns on money not spent on a down payment and maintenance.
Monthly Cost (Buy) = Mortgage + Tax + Insurance + Maintenance − Equity
Monthly Cost (Rent) = Rent + Renter's Insurance
Frequently Asked Questions
Is buying always better than renting?
No. Renting can be financially superior if you plan to move within 5 years, if housing prices are overvalued, or if you can invest the savings from lower rent payments at returns exceeding home appreciation. The break-even point is typically 5–7 years.
What costs are often forgotten when buying?
Closing costs (2%–5% of price), property taxes, homeowner’s insurance, HOA fees, maintenance and repairs (1%–2% annually), and the opportunity cost of the down payment are frequently underestimated by first-time buyers.
How does home appreciation affect the comparison?
Historical U.S. home appreciation averages 3%–4% annually, but varies widely by market. In high-appreciation areas, buying tends to win sooner. In stagnant markets, the investment returns from renting and investing may outperform homeownership.
