About the Rent vs. Buy Calculator
The rent vs. buy decision is one of the most consequential financial choices you'll make. Buying builds equity and locks in housing costs, but carries risks and costs that renting avoids: maintenance, property taxes, insurance, and opportunity cost on the down payment.
This calculator compares the net present value (NPV) of renting versus buying over a specified time horizon. It accounts for rent escalation, mortgage payments, property taxes, home insurance, maintenance, home appreciation, tax benefits, and the investment return you'd earn on the down payment if you rented instead.
The result shows which option is financially better for your specific situation and the break-even year where buying starts to win. Short time horizons typically favor renting; longer stays favor buying.
Homebuyers, investors, and real-estate professionals all benefit from precise rent vs. buy figures when evaluating properties, negotiating deals, or planning long-term investment strategies. Save this calculator and revisit it whenever market conditions or your financial situation changes.
When This Page Helps
Conventional wisdom says "buying is always better," but that depends heavily on your local market, how long you'll stay, and what you'd do with the money otherwise. This calculator runs the full analysis so you can decide with data, not assumptions.
How to Use the Inputs
- Enter the home purchase price and your down payment percentage.
- Set the mortgage rate and term (15 or 30 years).
- Enter annual property tax rate, home insurance, and maintenance as a % of home value.
- Enter current monthly rent and expected annual rent escalation.
- Set the expected home appreciation rate and investment return rate.
- Choose numbers of years to compare (5, 10, 15, 20, 30).
- View the NPV comparison and break-even year.
Formula used
Monthly Mortgage = P × [r(1+r)^n] / [(1+r)^n − 1]
Annual Buy Cost = Mortgage + Taxes + Insurance + Maintenance − Equity Gained − Tax Benefit
Annual Rent Cost = Rent × 12 + Renter Insurance − Investment Return on Down Payment
NPV = ∑ (Annual Net Cost / (1 + discount rate)^year)Example Calculation
Result: Buying is $32,000 cheaper over 10 years
With a $400,000 home (20% down, 6.5% rate) versus $2,000/month rent escalating 3%/year, buying costs approximately $445,000 total over 10 years while renting costs $277,000. However, the buyer builds ~$95,000 in equity and the home appreciates ~$75,000, making buying $32,000 cheaper on a net basis over the decade.
Tips & Best Practices
- If you'll stay fewer than 5 years, renting is almost always cheaper due to closing costs and slow equity build.
- Factor in the opportunity cost of your down payment — that money could earn 7–10% in equities.
- Home maintenance averages 1–2% of home value per year and is easy to underestimate.
- Don't forget property taxes and HOA fees in the buying calculation.
- Buying makes more financial sense in markets where rent-to-price ratios are high (rent is expensive relative to home prices).
- Consider non-financial factors: stability, customization freedom, and lifestyle preferences.
The True Cost of Homeownership
Many first-time buyers focus on the mortgage payment but underestimate the full cost: property taxes (1–3% of value), insurance (0.3–1%), maintenance (1–2%), HOA fees ($200–$500/month in condos), and closing costs (2–5%). These add 30–60% on top of the mortgage payment.
The Hidden Benefit of Renting
Renters get flexibility and the ability to invest their down payment savings in diversified assets. If the stock market returns 8% while home prices rise 3%, the renter's investment outperforms the buyer's equity gain. This opportunity cost is often overlooked in simplistic rent vs. buy comparisons.
Making Your Decision
Run this calculator with your actual numbers, then weigh the non-financial factors: do you want the stability and control of ownership, or the flexibility and simplicity of renting? The best financial choice isn't always the best life choice.

Frequently Asked Questions
The typical break-even point is 5–7 years, but it varies by market. In expensive markets with low appreciation, it can be 10+ years. In affordable markets with strong appreciation, it may be as few as 3–4 years. Use this calculator with your specific numbers.
Yes. You can set the expected annual home appreciation rate. Historically, U.S. home prices have appreciated 3–4% annually on average, though this varies significantly by location and time period.
Mortgage interest and property taxes are deductible if you itemize. However, the tax reform that doubled the standard deduction means fewer homeowners benefit from itemizing. This calculator factors in a simplified tax benefit estimate.
Yes, closing costs (2–5% of home price) are a significant upfront expense of buying and are factored into the analysis. They increase the break-even timeline by 1–2 years compared to ignoring them.
A diversified equity portfolio has historically returned 7–10% annually before inflation. Using 7% is a conservative assumption. This represents what you'd earn investing the down payment and monthly cost savings from renting.
Higher rent escalation makes buying look better over time because renting costs grow exponentially while a fixed-rate mortgage stays flat. At 3% escalation, rent doubles in 24 years. At 5%, it doubles in 14 years. This compounding drives the long-term advantage of buying.
