How to Use This Rent vs Buy Calculator
Enter your renting and buying scenarios side by side to find your financial break-even point.
Quick Compare Tab
Enter Monthly Rent and Annual Rent Increase on the renting side, and Home Price, Down Payment %, Mortgage Rate, and Home Appreciation on the buying side. The calculator shows the break-even year (when buying's equity first exceeds the renter's investment portfolio) and a comparison table for key years. Click "More options" to customize maintenance rate, insurance, property tax, and investment return assumptions.
Detailed Analysis Tab
This tab shows a full year-by-year breakdown comparing home equity growth versus a renter's investment portfolio, with the break-even year highlighted in green. Use this to see how sensitive the outcome is to your assumptions.
How the Calculation Works
Renter's Monthly Cost = Current Rent × (1 + Annual Increase)^year
Buyer's Net Worth = Home Equity = Home Value − Remaining Loan Balance
Home Value(year n) = Purchase Price × (1 + Appreciation)^n
Renter's Net Worth = Investment Portfolio
Renter invests the down payment + monthly cost savings vs buying
Portfolio grows at the assumed investment return rate
Break-Even Year = First year where Buyer Net Worth ≥ Renter Net Worth
The model assumes the renter invests the down payment they would have used, plus any monthly cost difference between renting and buying, in a diversified investment portfolio. This is a key assumption — if the renter doesn't invest, buying wins much sooner.
Example: Austin, TX — Rent $2,000 vs Buy $350,000
Alex's Decision — Austin, TX
Alex pays $2,000/month rent with 3% annual increases. They could buy a $350,000 home with 20% down at 6.75% with 3.5% appreciation.
| Monthly Rent | $2,000 |
| Rent at Year 10 | $2,688 |
| Rent at Year 20 | $3,613 |
| Monthly Mortgage (P&I) | $1,816 |
| Total Monthly Buy Cost | ~$2,700 |
| Down Payment Invested | $70,000 → ~$254K (30 yrs at 6%) |
| Home Value at Year 30 | ~$986,000 |
| Home Equity at Year 30 | ~$986,000 |
| Break-Even Year | ~Year 7 |
In this scenario, Alex's monthly cost to buy is higher than rent initially. But the mortgage payment stays fixed while rent rises 3% annually. By year 7, home equity surpasses the renter's investment portfolio. By year 30, the homeowner is ahead by approximately $500,000.
