Rent vs Buy Calculator
Compare the long-term costs of renting versus buying a home, taking into account monthly rent payments, mortgage payments, home appreciation, and property expenses.
Calculation Results
Estimated monthly mortgage payment (assuming 30-year fixed loan).
Total rent paid over the timeline.
Estimated home value after appreciation (assuming 3% annual growth).
Remaining mortgage balance after the specified timeline.
Estimated cash returned to you upon selling (Future Value minus Remaining Mortgage Balance).
Total out-of-pocket costs of ownership including down payment, mortgage payments, and maintenance/taxes/insurance estimated at 2.5% of purchase price annually.
Net buying cost (Gross Buying Costs minus Net Equity gained).
The net savings from buying rather than renting. A positive number means buying is cheaper; negative means renting is cheaper.
How This Calculator Works
To compare renting versus buying:
- Enter your estimated monthly rent cost for the rental option.
- Enter the buying parameters: purchase price, down payment, and mortgage interest rate.
- Specify how many years you expect to reside in the property.
The calculator estimates the future home value, equity buildup, gross expenditures, and presents a clear comparison of which path is more financially beneficial.
Formula & Calculations
This calculator compares the absolute financial outcomes of renting versus buying a home over a specified timeline:
- Total Cost of Renting: The monthly rent multiplied by 12 months and the years in the home:
- Gross Cost of Buying: The sum of the down payment, mortgage payments (P&I) over the years, and a yearly property maintenance/tax/insurance fee estimated at 2.5% of the purchase price:
- Net Equity: The appreciated value of the home minus the remaining loan balance at the end of the timeline:
- Net Cost of Buying: Gross costs minus the equity you recover when selling the home:
- Financial Difference: The total cost of renting minus the net cost of buying:
Rent Cost = Monthly Rent × 12 × Years
Gross Buying Costs = Down Payment + (Monthly Mortgage × 12 × Years) + (Home Price × 0.025 × Years)
Net Equity = Future Value - Remaining Mortgage Balance
Where Future Value = Home Price × (1 + 0.03)^Years (assuming a conservative 3% annual appreciation rate).
Net Buying Cost = Gross Buying Costs - Net Equity
Difference = Total Rent Cost - Net Buying Cost

Frequently Asked Questions
Is it always better to buy than to rent?
No. Renting can be better if you plan to stay in the home for a short period (under 3-5 years) because the upfront buying costs and selling commissions will not have time to be offset by home appreciation and principal paydown. Renting also offers more flexibility and eliminates maintenance costs.
What home price appreciation rate is assumed?
The calculator assumes a conservative 3% annual appreciation rate, which is in line with long-term historical averages in the United States.
Why are maintenance and taxes estimated at 2.5%?
On average, homeowners spend about 1% of their home value per year on maintenance and repairs, and property taxes and insurance average 1% to 1.5% annually. Combining these gives a standard 2.5% annual holding cost for property.
