Rent vs Buy Calculator

Compare the total cost of renting versus buying a home over time. See breakeven year, equity buildup, and opportunity cost of your down payment.

Quick Answer

The rent vs. buy breakeven point is typically 5-7 years, depending on home prices, interest rates, and local rent growth. Buying makes financial sense when monthly mortgage payments (including taxes, insurance, and maintenance at roughly 1-2% of home value annually) are comparable to rent, and you plan to stay long enough to recoup closing costs (typically 2-5% of purchase price). The opportunity cost of a down payment invested in the stock market at ~7% annual returns must also be considered.

About This Tool

The Rent vs Buy Calculator helps you compare the true financial cost of renting versus buying a home over time. It goes beyond the simplistic “rent is throwing money away” framing and looks at the full picture: mortgage payments, property taxes, insurance, maintenance, HOA fees, closing costs, equity buildup, and the opportunity cost of your down payment.

One of the most overlooked factors in the rent vs buy decision is opportunity cost. When you put $80,000 down on a $400,000 home, that money is no longer available to invest in the stock market, bonds, or other assets. This calculator models what that money could have grown to, giving you a more honest comparison.

How the Comparison Works

On the renting side, the calculator tracks cumulative rent payments over time, increasing annually by your specified rent increase rate. It also includes renter's insurance. On the buying side, it tracks mortgage payments (principal and interest), property taxes, homeowner's insurance, HOA fees, and maintenance costs. The net cost of buying subtracts equity buildup through principal payments, since that money is effectively yours.

The breakeven point is the year when the cumulative net cost of buying drops below the cumulative cost of renting. If you plan to stay shorter than the breakeven period, renting is likely more cost-effective. If you plan to stay longer, buying tends to win financially.

Key Factors That Shift the Result

Several inputs have an outsized impact on the result. A higher interest rate makes buying more expensive and pushes the breakeven point further out. A higher expected investment return makes renting more attractive since your alternative investments grow faster. Higher rent increases favor buying, while higher property taxes and HOA fees favor renting. Adjusting these inputs helps you see how sensitive the result is to your assumptions.

Frequently Asked Questions

How does the rent vs buy calculator determine the breakeven point?
The breakeven point is the year when the cumulative net cost of buying becomes less than the cumulative cost of renting. Net buy cost accounts for mortgage payments, taxes, insurance, HOA, and maintenance, minus the equity you build through principal payments. It also factors in the opportunity cost of your down payment.
What is the opportunity cost of a down payment?
When you use savings for a down payment, that money can no longer be invested in stocks, bonds, or other assets. The calculator models what your down payment and closing costs would have grown to if invested at your expected return rate, giving you a true apples-to-apples comparison with buying.
Does the calculator account for home price appreciation?
This version uses a conservative approach and does not assume home price appreciation. This makes the comparison more objective since future home values are uncertain. In practice, if your home appreciates, buying becomes even more favorable. If it depreciates, renting looks better.
What costs are included in the monthly buy calculation?
The monthly buy cost includes principal and interest (P&I), property tax, homeowner's insurance, HOA fees, and estimated maintenance (typically 1% of home value per year). Closing costs and the down payment are included as upfront costs in the cumulative calculation.
Should I use this calculator to make my rent vs buy decision?
This calculator provides a financial comparison, but the rent vs buy decision involves more than numbers. Consider lifestyle factors like job mobility, family plans, local market conditions, and personal preferences. Use this tool as one input in your decision, and consult with a financial advisor for personalized advice.
