How this calculation works
The Rent vs. Buy Breakeven Calculator compares the long-term financial trajectory of homeownership (mortgage payments, equity building, property taxes, maintenance, selling costs) against renting while investing the down payment difference in index funds.
Mathematical formula and logic
Breakeven Year = The point in time where accumulated homeowner net equity minus buying/selling transaction costs exceeds the accumulated portfolio value of renting and investing.
Worked example
Comparing $2,000/mo rent against buying a $400,000 home (20% down, 6.5% rate, 4% appreciation): Buying breaks even in Year 4. By Year 10, buying generates ~$142,000 more net wealth than renting.
Calculation assumptions
- Annual home maintenance budgeted at 1.0% of property value per year.
- Buyer closing costs estimated at 3%; future seller agent commission estimated at 6%.
Frequently asked questions
How many years does it usually take for buying a home to beat renting?
In most housing markets, the breakeven horizon is 3 to 6 years. If you plan to move in less than 3 years, renting is almost always cheaper due to high closing and realtor selling transaction fees.
Is rent considered 'throwing money away'?
No. Renting buys immediate shelter, flexibility to relocate for job opportunities with zero selling costs, and transfers all property tax, maintenance, and market depreciation risk to the landlord.
What is the 5% Rule for real estate vs renting?
The 5% Rule estimates unrecoverable homeownership costs as ~5% of the property value per year (1% property tax + 1% maintenance + ~3% cost of capital/mortgage interest). If annual rent is less than 5% of home price, renting is often financially advantageous.
How does inflation impact homeownership vs renting?
A fixed-rate mortgage locks in your principal and interest payment for 30 years while rents typically rise with inflation, making homeownership increasingly affordable relative to income over time.
What if the stock market outperforms real estate appreciation?
Stock investments often provide higher annual percentage returns (7-10% vs 3-5% real estate), but real estate enables 5x leverage (a 20% down payment controls 100% of the appreciating asset).
