What Is a Rent vs Buy Calculator?
Deciding whether to rent or buy a home is one of the most significant financial decisions most people face. The right choice depends on your time horizon, local market conditions, investment returns, and personal goals. This calculator compares the true long-term financial outcome of renting versus buying over a period you choose.
As of July 2026, the housing market presents a complex picture. The Freddie Mac 30-year fixed mortgage rate averaged 6.49%, the National Association of Realtors reported a median existing-home price of $440,600, and Realtor.com reported a national median asking rent of $1,692 for 0-2 bedroom properties. The S&P Case-Shiller Index showed just 0.9% annual home price growth as of February 2026, meaning appreciation has slowed dramatically compared to the pandemic years.

What This Calculator Does
Rather than just comparing monthly rent to mortgage payments, this tool accounts for down payment opportunity cost, home appreciation, rent increases, property taxes, maintenance, and investment returns if you had rented instead.
Inputs Required
- Home Price: Purchase price of the home being considered (U.S. median was $440,600 in June 2026)
- Down Payment: Percentage of home price paid upfront
- Mortgage Rate: Annual interest rate on the home loan (30-year fixed averaged 6.49% in July 2026)
- Property Tax Rate: Annual property tax as a percentage of home value
- Maintenance Rate: Annual maintenance cost as a percentage of home value
- Home Appreciation Rate: Expected annual growth in home value (Case-Shiller showed 0.9% as of February 2026)
- Monthly Rent: Current rent payment (national median was $1,692 in June 2026)
- Annual Rent Increase: Expected percentage increase in rent each year
- Investment Return: Annual return if down payment were invested instead
- Years to Analyze: How long you plan to stay in the home
Outputs Provided
- Verdict: Whether buying or renting is financially better over your chosen period
- Net Position: The financial outcome for each option after all costs
- Break-Even Year: When buying becomes more advantageous than renting
- Chart: Visual comparison of net positions over time
How the Calculation Works
Buy Net = Home Equity - Total Costs Paid (mortgage, tax, insurance, maintenance)
Rent Net = Invested Down Payment Growth - Total Rent Paid
Break-Even Year = First year Buy Net exceeds Rent Net
The buy scenario tracks total cash spent (mortgage payments, taxes, insurance, maintenance, down payment, and closing costs) against growing home equity from appreciation and loan paydown. The rent scenario assumes the down payment plus closing costs are invested at the stated return rate, offset by total rent paid.
This comparison is not a judgment that one is always better. It is a tool to see which makes more financial sense for your specific numbers and time frame. Non-financial factors such as stability, flexibility, and lifestyle should also be considered.
How to Use the Calculator
- Enter the home price and your planned down payment percentage
- Input your expected mortgage rate (6.49% is the July 2026 average for a 30-year fixed)
- Enter your property tax rate, insurance, and maintenance estimates
- Enter your home appreciation assumption (use 2% to 4% for conservative planning, not the 0.9% recent figure which may be cyclical)
- Input your current rent and expected annual rent increase (rents have been declining 1.5% year over year as of June 2026, but 2% to 3% is a reasonable long-term assumption)
- Enter what you estimate you could earn investing the down payment (historical stock market averages around 7%)
- Select how many years you plan to stay
- Read the verdict and examine the chart for the break-even point
Example Calculations
Example 1: Median U.S. Home vs Median Rent
A buyer considers a $440,600 home (the June 2026 U.S. median) with 20% down ($88,120) at 6.49% for 30 years, versus renting at $1,692/month (the June 2026 national median) with 2% annual increases. Assumptions: 3% home appreciation, 7% investment return, 1.2% property tax, $1,500 annual insurance, 1% maintenance.
- Up-front costs: $88,120 down + approximately $13,200 closing costs
- Monthly mortgage (P&I): approximately $2,229 on a $352,480 loan
- Monthly ownership costs (with tax, insurance, maintenance): approximately $2,884
- Monthly rent: $1,692 (rising 2% per year)
- After 10 years: Buying is better by approximately $30,000 to $50,000 depending on appreciation
- Break-even typically occurs around year 6 to 8 in this scenario
Example 2: Short Stay in a High-Cost Market
Emily is relocating to San Francisco for a 3-year assignment. She considers a $1.2 million condo with 20% down at 6.49%, versus renting a comparable unit for $4,200/month. Closing costs alone are approximately $36,000. The calculator shows that buying does not break even within 3 years because closing costs and the early years of mortgage interest outweigh any appreciation gains. Renting is clearly the better financial choice for her time horizon.
Example 3: Long-Term Buyer in Cleveland
Marcus buys a $180,000 home in Cleveland with 20% down ($36,000) at 6.49%. Comparable rent is $1,200/month. His monthly ownership costs are approximately $1,450 (mortgage, tax, insurance, maintenance), slightly higher than rent. However, over 15 years with 3% appreciation and 2% rent increases, buying wins by approximately $80,000 to $120,000 due to equity buildup and the fact that his mortgage payment stays fixed while rent increases every year. The break-even occurs around year 4 to 5.
Real-World Scenarios
2026 Market Dynamics
The 2026 housing market creates an unusual rent vs buy dynamic. Mortgage rates at 6.49% make borrowing expensive, but the median home price of $440,600 combined with 0.9% annual appreciation (per Case-Shiller February 2026) means buyers are not seeing rapid equity gains. Meanwhile, rents have been declining for 35 consecutive months as of June 2026, with the national median at $1,692, down 1.5% year over year. This combination has extended the break-even horizon in many markets. However, if rates decline or appreciation accelerates, the calculus could shift quickly. The calculator lets you model these scenarios by adjusting the rate and appreciation inputs.
Short Stay (Under 3 Years)
Someone relocating for work plans to stay only two to three years. Closing costs (2% to 5% of the purchase price) and the initial high-interest portion of mortgage payments mean buying rarely makes financial sense over such a short period. On a $440,600 home, closing costs of $8,800 to $22,000 take years to recover. Renting preserves flexibility and typically wins on the numbers at this time horizon.
Long-Term Buyer in an Appreciating Market
A buyer in a city with historically strong home price growth plans to stay 15 or more years. Even with high upfront costs and a 6.49% mortgage rate, appreciation compounds over time and builds significant equity. The fixed mortgage payment becomes an advantage as rent increases erode the renter's position. Buying wins decisively in the long run, especially if the buyer makes extra principal payments to accelerate equity growth.
Why This Calculation Matters
The rent vs buy decision is never as simple as comparing a mortgage payment to a rent payment. Owning a home comes with costs that renters do not pay, including property tax, maintenance, insurance, and the opportunity cost of the down payment. At the same time, ownership builds equity and provides a hedge against rising housing costs over time. The Harvard Joint Center for Housing Studies reported in 2026 that cost burdens affect both renters and homeowners, with 22.7 million renter households spending more than 30% of income on housing.
Using a calculator like this reveals your personal break-even point, which is the minimum time you need to stay in a home before buying makes financial sense. This is critical information before committing to a 30-year mortgage at 6.49%.
Common Mistakes to Avoid
- Comparing mortgage to rent directly: The mortgage payment is only part of the cost of ownership. Add property tax, insurance, and maintenance to get a true comparison. On a $440,600 home, these can add $500 to $800 per month
- Ignoring the down payment opportunity cost: The money used as a down payment could be invested. At 7% annual returns, an $88,000 down payment grows to $173,000 over 10 years. This calculator accounts for that as part of the renting scenario
- Overestimating appreciation: The S&P Case-Shiller Index showed just 0.9% annual growth as of February 2026. Using overly optimistic appreciation rates skews the results toward buying. Use conservative, historically grounded estimates of 2% to 4%
- Not factoring in your time horizon: Buying almost always wins over 20 to 30 years. But if you might move in 3 years, the math often favors renting due to closing costs and transaction fees
- Forgetting closing costs: Both buying and selling a home involve closing costs. Buying costs 2% to 5% of the purchase price, and selling costs another 6% to 8% (including realtor commissions). On a $440,600 home, that is $35,000 to $57,000 in total transaction costs
