Rent vs Buy Calculator:
Should You Rent or Buy a Home in 2026?
Most people only compare monthly rent to a mortgage payment. We show you the full picture, including taxes, maintenance, appreciation, and the opportunity cost of your down payment.
Is It Better to Rent or Buy a Home?
The answer depends on your monthly rent, home price, mortgage rate, and how long you plan to stay. In most U.S. markets, buying becomes cheaper than renting after 5-7 years due to equity building and fixed mortgage payments. Enter your numbers below to find your exact break-even year.

How the Rent vs Buy Math Works
Deciding between renting and buying isn't just about monthly cash flow. It's about comparing the total cost of occupancy over time.
Appreciation & Equity
Buying builds wealth through principal paydown and home value growth. This equity often makes buying superior in the long run.
The Cost of Renting
Renting has zero maintenance costs and maximum flexibility, but your housing costs are likely to rise 3-5% every year due to inflation.
Opportunity Cost
A renter can invest their down payment elsewhere (like the stock market). Our calculator accounts for these "lost" earnings to give you the true answer.
Pro Tip: The 5-Year Rule
Generally, if you plan to stay in your home for less than 5 years, renting is usually the safer financial bet.
This is because the high upfront costs (closing costs) and exit costs (realtor fees) often eat up any equity or appreciation gains in the early years.

This calculator compares the full financial picture of renting against buying a home over a user-defined time horizon. It goes beyond comparing a monthly mortgage payment to rent — it accounts for every recurring cost of ownership, the appreciation of the asset, the compounding effect of rent inflation, and the opportunity cost of capital tied up in a down payment.
Every figure is derived from standard financial formulas. None of the math is hidden. If you want to understand exactly why the calculator produces a given result, this section explains each model component in detail.
Mortgage Amortization Formula
Definition: What is mortgage amortization?
Mortgage amortization is the process of paying off a home loan through a schedule of fixed monthly payments. Each payment covers the interest owed on the remaining balance and reduces that balance by the remainder. Because the balance is highest at the start, early payments are mostly interest. The share of each payment going to principal increases gradually every month until the loan is paid off.
For a detailed breakdown of the amortization formula and how monthly schedules are calculated, see our Mortgage Amortization Guide.
The monthly mortgage payment is calculated using the standard amortization formula:
- P — Loan principal (home price minus down payment)
- r — Monthly interest rate (annual rate ÷ 12)
- n — Total number of payments (loan term in years × 12)
For example, a $450,000 loan at 6.5% for 30 years: r = 0.065 ÷ 12 = 0.005417; n = 360. The monthly P&I payment is $2,844. In month 1, $2,438 is interest and only $406 reduces the principal balance. By year 10, the split shifts to roughly $2,100 interest and $744 principal per month as the balance falls.
Property Tax Modeling
Property taxes are modeled as a fixed percentage of the home's current assessed value. In most U.S. jurisdictions, the effective tax rate falls between 0.5% and 2.5% annually. The calculator applies your specified rate to the home value each year, which rises with the appreciation assumption. On a $500,000 home at a 1.2% rate, annual property taxes start at $6,000 (or $500/month) and increase as the home appreciates.
This is a simplification — some states cap annual assessment increases (Proposition 13 in California, for instance), and effective rates vary widely by county. The user-adjustable rate allows you to match your specific local tax burden. A detailed explanation of property tax variation by region is covered in our closing costs guide.
Maintenance Cost Assumptions
Annual maintenance is modeled as a percentage of the home's current value. The widely cited rule of thumb is 1% per year; more conservative estimates use 1.5–2%, particularly for older homes or those in harsher climates. On a $500,000 home at 1%, annual maintenance costs start at $5,000 and grow as the home's value increases with appreciation.
Maintenance is one of the most underestimated costs in homeownership. Individual years may see little expense; others can see $15,000–$30,000 in a single major repair. The percentage model averages these lumpy costs into an annual figure. Budget-conscious buyers should read the hidden costs of homeownership guide before setting their maintenance assumption.
Rent Inflation Logic
Rent is compounded annually at the user-specified inflation rate. At 4% annual growth, a starting rent of $2,800 per month reaches $4,147 after 10 years and $6,143 after 20 years. This compounding effect is what makes long-term renting increasingly expensive over time compared to a fixed-rate mortgage.
Historical U.S. rent inflation has averaged approximately 3–4% annually over long periods, though it has spiked as high as 8–12% in tight markets (2021–2022) and fallen near zero in oversupplied markets. The default 3.5% is a conservative long-run estimate.
Home Appreciation Modeling
Home value is compounded annually at the user-specified appreciation rate. The default assumption (3%) reflects the long-run U.S. median as measured by the Federal Housing Finance Agency (FHFA) index, net of inflation. Appreciation directly affects both the net equity calculation (which improves the buyer's position) and the maintenance and property tax costs (which both grow with home value).
Appreciation is the most consequential and least predictable input. A 1-percentage-point change in the annual rate generates a difference of roughly $50,000–$80,000 in net home value over 10 years on a $500,000 home, which can swing the break-even year by 2–3 years. We strongly recommend stress-testing the calculation at 1%, 3%, and 5% appreciation to understand the range of outcomes.
Opportunity Cost of Capital
The down payment represents capital that could earn a return if invested rather than spent on housing. The calculator compounds the down payment amount at the user-specified investment return rate to estimate what that capital would be worth if not tied up in a home. This opportunity cost is credited to the renting scenario.
At a 6% annual return, $80,000 invested at purchase grows to roughly $143,000 after 10 years. This $63,000 gain belongs to the renter scenario — it partially offsets the equity the buyer accumulates through amortization and appreciation. In high-appreciation markets, the home often outpaces the alternative investment; in flat markets, the invested down payment wins.
How to Interpret Your Results
The calculator outputs two primary figures for each time horizon: the total cost of renting and the total cost of buying, both expressed in cumulative dollar terms. The difference between them is the net financial advantage of one option over the other at that point in time.
What does the break-even year mean?
The break-even year is the first year at which the cumulative cost of buying drops below the cumulative cost of renting. Before that year, renting has cost less in total. After that year, buying has cost less. If you plan to stay longer than the break-even year, buying has been the cheaper option in aggregate. If you plan to move before it, renting has been cheaper.
What does a negative net cost difference mean?
A negative net cost difference means renting has been cheaper up to that point. A positive net cost difference means buying has been cheaper. The crossover from negative to positive marks the break-even point. In high-rate or high-price environments, the number may stay negative for 10+ years, indicating that renting is more cost-effective for any time horizon up to that point.
Why are small rate changes so significant?
Because the mortgage payment formula is exponential with respect to the interest rate, small changes create large compounding differences. Moving from 6% to 7% on a $450,000 loan adds approximately $280/month to the P&I payment. Over 10 years that is $33,600 more paid before accounting for amortization differences. This is why the break-even year is so sensitive to rate assumptions — always run the calculation at a range of rates, especially given today's rate uncertainty.
Long-term vs short-term outcomes diverge significantly because of two compounding forces working in opposite directions for buyers: the mortgage balance declines as equity accumulates (improving the buyer's position) while rent inflation continuously worsens the renter's ongoing costs. For stays beyond 10 years, buying generally wins in most U.S. markets at any reasonable appreciation assumption. For stays under 4 years, renting generally wins unless the price-to-rent ratio is unusually low.

What This Tool Does Not Include
Transparency about limitations is as important as the calculations themselves. The following factors are not modeled in the current version and should be considered qualitatively alongside the calculator's output.
Local Tax Law Changes
Property tax rates can change due to municipal budgets, ballot initiatives, or state legislation. The calculator assumes a static effective rate. Buyers in jurisdictions with rapidly rising assessments may face higher actual costs.
HOA Volatility
Homeowners associations can raise dues, levy special assessments for unexpected repairs, or impose restrictions that affect quality of life and resale value. These costs are not predictable and are not modeled.
Market Downturn Risk
The appreciation model assumes steady annual growth. Real markets cycle. A 15–20% price correction shortly after purchase can take years to recover, and if a forced sale occurs in a down market, realized losses can be severe.
Selling Transaction Timing
The model deducts selling costs at the terminal year. In reality, the decision of when to sell is uncertain and market-dependent. A forced sale in a down cycle or a delay of 12–18 months to find a buyer can significantly alter the net outcome.
Emotional Value of Ownership
Stability, the ability to customize, and the sense of permanence attached to homeownership have real value that cannot be quantified. Some households will rationally pay a financial premium for these benefits.
Tax Deductibility of Mortgage Interest
The mortgage interest deduction benefits only taxpayers who itemize deductions. Since the 2017 Tax Cuts and Jobs Act raised the standard deduction, the majority of homeowners no longer benefit from itemizing. This calculator does not model tax scenarios.
Full Worked Example
The following example walks through the full calculation using a realistic scenario. Every number below can be reproduced by entering the same inputs into the calculator above.
Scenario Inputs
Step 1: Monthly Payment Calculation
Loan principal = $500,000 − $50,000 = $450,000. Monthly rate r = 6.5% ÷ 12 = 0.5417%. Payments n = 360.
Add property tax and maintenance in year 1:
- Property tax: $500,000 × 1.2% ÷ 12 = $500/mo
- Maintenance: $500,000 × 1.0% ÷ 12 = $417/mo
- Total year-1 ownership cost: $3,761/mo vs $2,800 rent — buying costs $961 more per month at the outset.
Step 2: 5-Year and 10-Year Cumulative Cost Breakdown
| Metric | Year 5 | Year 10 |
|---|---|---|
| Total mortgage P&I paid | $170,640 | $341,280 |
| Property tax paid (grows with value) | $31,500 | $68,500 |
| Maintenance paid (grows with value) | $26,250 | $57,100 |
| Closing costs (upfront, year 0) | $15,000 | $15,000 |
| Total buying cost (gross) | $243,390 | $481,880 |
| Home value at appreciation 3%/yr | $579,637 | $671,958 |
| Remaining mortgage balance | $420,700 | $391,200 |
| Gross equity (value − balance) | $158,937 | $280,758 |
| Net buying cost (gross cost − equity) | $84,453 | $201,122 |
| Total rent paid (4% annual growth) | $184,000 | $411,000 |
| Opportunity cost of $50K down (6%/yr) | $16,900 | $39,500 |
| Net renting cost (rent + opp. cost) | $200,900 | $450,500 |
| Net advantage of buying | Renting cheaper by ~$116K | Renting cheaper by ~$250K |
All figures are rounded estimates for illustration. Results from the live calculator may differ slightly due to precise monthly compounding.
Step 3: Break-Even Estimate
In this scenario, the high upfront cost of buying plus the monthly ownership premium ($961/mo more than rent in year 1) means the renter has a large cost lead in the early years. However, rent inflation at 4% annually means the renter's monthly cost reaches $3,412 by year 5 and $4,147 by year 10 — gradually eroding the renter's advantage.
With these specific inputs, the break-even point falls at approximately year 14–16. Before that point, renting is cheaper in aggregate. After that point, the buyer has accumulated enough equity and the renter's cumulative rent payments have grown enough that buying becomes the lower total-cost option.
Key takeaway from this example
At 6.5% interest, 10% down, and a $500,000 home with $2,800 rent, buying requires a long-term commitment to pay off financially. If you plan to stay 15+ years, the buyer wins comfortably. If you plan to move within 10 years, renting has been cheaper in this scenario. Small changes to appreciation rate (up to 4%) or rent inflation (up to 5%) shift the break-even earlier — which is why the calculator is more useful than any static example.

Frequently Asked Questions
How does a rent vs buy calculator work?
A rent vs buy calculator compares the total cost of renting over time against buying. It factors in monthly payments, closing costs, maintenance, property taxes, appreciation, rent growth, and the opportunity cost of your down payment to show which option costs less over different time periods.
What is the rent vs buy break-even point?
The break-even point is when buying becomes cheaper than renting. It typically ranges from 5-7 years but depends on your local market, interest rate, and rent-to-price ratio. Our calculator shows your exact break-even year based on your inputs.
Should I rent or buy if I might move in 3 years?
If you plan to move within 3 years, renting is usually the better choice. The upfront costs of buying (closing costs, moving expenses) and selling costs (agent commissions) are difficult to recover in a short timeframe.
How does opportunity cost affect the rent vs buy decision?
Opportunity cost is what your down payment could earn if invested elsewhere. If you put $80,000 down on a house, that money can not earn stock market returns. A good calculator factors this lost investment growth into the buying scenario.
Is renting always throwing money away?
No. Renting provides housing, flexibility, and frees up cash for other investments. In expensive markets or for short stays, renting often costs less than buying when all costs are considered.
