Rent vs Buy Calculator
Compare renting vs. buying a home over your desired timeframe. Account for mortgage, taxes, insurance, maintenance, rent increases, home appreciation, and investment returns. Transparent assumptions, no hidden costs.
Rent vs Buy Calculator
How this works: This calculator compares buying vs. renting over a specific time period, accounting for home appreciation, rent increases, taxes, insurance, maintenance, investment returns, and opportunity costs. Results are scenario estimates only, not predictions of future markets or individual circumstances.
How the Calculation Works
Comparison Method: This calculator compares the financial outcome of buying vs. renting over your specified time period. It models:
- Buying: Down payment, mortgage principal & interest, property taxes, homeowners insurance, maintenance, buyer closing costs, and estimated selling costs if selling at the end of the period. Accounts for home appreciation and the remaining mortgage balance after your comparison period.
- Renting: Total rent (with annual increases), renters insurance, and invested wealth from the down payment and any monthly savings if renting is cheaper.
- Investment Comparison: The calculator accounts for investment returns on money that could be invested by either party. A buyer's down payment and closing costs are opportunity costs; a renter can invest those funds plus any monthly savings.
Output: Net financial position for each scenario—the amount you would have if you sold the home (or held it) vs. your invested wealth as a renter. The break-even point depends entirely on your scenario assumptions; there is no universal timeline.
Worked Example
Scenario: $350,000 home with 20% down ($70,000), 6.5% mortgage for 30 years, $1,800/month starting rent, compared over 10 years with 3% annual home appreciation, 2.5% annual rent increases, and 7% investment returns.
- Buyer Upfront Costs: $70,000 down + $8,000 closing = $78,000
- Buyer Monthly (P&I, taxes, insurance, maintenance): ~$2,170
- Mortgage Principal Paid Down: Principal payments total ~$40,000 over 10 years
- Home Value After 10 Years: $350,000 × (1.03)^10 = $469,727
- Remaining Mortgage Balance: ~$241,000
- Buyer Net Position (if selling): $469,727 − $241,000 − $28,184 (6% selling costs) = $200,543
- Renter Monthly: Starting $1,800, increasing 2.5% annually; avg ~$2,023 plus renters insurance
- Renter Invested Wealth: $78,000 down payment invested at 7% = $137,884 after 10 years
- Outcome (this scenario): Buying is financially better by ~$62,659 due to principal buildup and appreciation, though both results vary with assumption changes.
Sensitivity: If home appreciation were 0% instead of 3%, or investment returns were 10% instead of 7%, results would be dramatically different. Test multiple scenarios to understand how sensitive the comparison is to market conditions and your assumptions.
How to Use This Calculator
Key Factors: The financial outcome depends heavily on assumptions. Most influential factors:
- Time Period: Shorter periods favor renting (transaction costs hurt buying). Longer periods favor buying if appreciating.
- Home Appreciation: Future price changes are uncertain and vary by location and time period. 0% appreciation, 3%, and 6% yield very different outcomes.
- Rent Growth: Rents typically increase over time. Higher growth rates make buying relatively more favorable.
- Interest Rates: Higher mortgage rates increase monthly payments and favor renting. Lower rates favor buying.
- Investment Returns: Higher alternative investment returns make renting more attractive (money not tied up in home equity grows faster elsewhere).
- Local Costs: Property tax rates, insurance, and maintenance vary significantly by location.
This is a scenario calculator: It shows what happens under YOUR specific assumptions, not a prediction of markets or a recommendation. Use it to understand how different factors affect the comparison, and test multiple scenarios with different assumptions rather than relying on a single forecast.
Frequently Asked Questions
What is the break-even point between renting and buying?
There is no universal break-even timeline. The break-even point depends entirely on your specific scenario—home price, location, interest rate, rent, appreciation assumptions, and investment returns. Use this calculator to find when (if ever) buying becomes more favorable given YOUR numbers. Some scenarios show buying is better after 3 years; others show renting is better for 20+ years.
Should I assume a certain home appreciation rate?
Future home-price changes are uncertain and vary significantly by location and time period. Historical average U.S. appreciation is around 3-4% annually, but past performance does not guarantee future results. Test multiple appreciation rates (0%, 2%, 3%, 5%) to see how sensitive your result is. Using a single "assumed" rate as if it were certain is a common planning mistake.
What about the tax benefits of homeownership?
Homeownership can have tax implications, but whether you receive a tax benefit depends on applicable tax law and your individual circumstances. This calculator does not model tax deductions. If mortgage interest or property tax deductions apply to your situation, consult current IRS guidance or a qualified tax professional. Do not assume a tax benefit applies without verification.
How does this calculator account for mortgage equity?
The calculator properly tracks how much of each mortgage payment goes to principal (building equity) vs. interest (financing cost). It calculates the remaining mortgage balance after your comparison period using standard amortization, then subtracts it from estimated home value to show net equity. Equity comes from two sources: principal repayment and home appreciation (or depreciation).
What if renting is cheaper but buying builds more wealth?
This can happen if home appreciation is strong or if you would invest additional money from the cheaper monthly rent payments. Conversely, even if buying has lower monthly costs, renting can build more wealth if investment returns are very high and home appreciation is low. The net position (not just monthly cost) determines which scenario is better financially over the long term.
Can I change the assumptions to match my situation?
Yes. Click "Advanced Assumptions" to adjust property tax rates, insurance, maintenance, closing costs, home appreciation, rent growth, and expected investment returns to match your local market and personal circumstances. Default values are illustrative starting assumptions only. Actual costs and future rates vary. Adjust them to match your scenario.
Is this financial or investment advice?
No. This calculator is for educational and planning purposes only. It does not predict future home prices, investment returns, rent changes, or individual tax outcomes. Rent-vs-buy decisions depend on many personal factors (job mobility, preferences, risk tolerance, financial goals) beyond pure financial calculation. Consult a qualified financial advisor, tax professional, or mortgage lender for advice specific to your situation.
