Whether renting or buying is the smarter financial move depends entirely on three numbers: your local market, your time horizon, and the current mortgage rate. At 2026 rates of 6.8%, buying the median US home costs roughly $1,000/month more than renting an equivalent unit before accounting for tax benefits, equity, and appreciation. The calculator above finds your personal break-even year and shows the true net cost of each option, year by year.
How the True Cost Comparison Works
Most rent-vs-buy comparisons make a critical error: they compare monthly rent to monthly mortgage payment and declare a winner. That misses the full picture on both sides.
What the “true net cost” method measures:
For buying, true net cost = all cash you pay out of pocket minus the money you recover when you sell. This means your down payment, closing costs, every mortgage payment, every property tax bill, every insurance premium, and every maintenance dollar — minus the equity you walk away with at sale (home value minus remaining mortgage minus selling costs).
For renting, true net cost = total rent paid minus the investment gain on your down payment alternative. If you rent instead of buy, you keep your down payment and invest it. Over time it grows — that growth reduces your effective housing cost.
This apples-to-apples comparison eliminates the bias in either direction and gives you the honest answer for your specific numbers.
What Input Numbers to Use
| Input | Suggested Default | Notes |
|---|---|---|
| Monthly Rent | Current rent | Use comparable unit rent if you don’t rent yet |
| Home Price | $422,000 | US median 2026; use local Zillow/Redfin data |
| Down Payment | 20% | Avoids PMI; adjust for your actual plan |
| Mortgage Rate | 6.8% | 30-year conventional, July 2026 average |
| Property Tax | 1.1% | National average; varies 0.3% (HI) to 2.5% (NJ) |
| Home Insurance | $1,800/yr | National average; higher in coastal/storm areas |
| Maintenance | 1.0% | Rule of thumb; older homes may need 1.5–2% |
| Appreciation | 3.5% | Long-run historical average; varies by market |
| Rent Increase | 3.0% | Approximate long-run US average |
| Investment Return | 7.0% | Historical S&P 500 average (real return ~5%) |
The single most important input is years you plan to stay. Nearly every analysis shows renting is cheaper in the first 1–4 years due to closing costs and low equity build-up in early mortgage years. Buying almost always wins over 10+ years due to appreciation and mortgage paydown.
The Break-Even Year by Market Type
How long before buying becomes cheaper than renting varies widely by metro. These are rough estimates based on 2026 price-to-rent ratios and mortgage rates.
| Market Type | Typical Break-Even | Example Cities |
|---|---|---|
| Affordable / low price-to-rent | 2–4 years | Cleveland, Pittsburgh, Detroit, Memphis |
| Mid-tier / balanced | 4–6 years | Dallas, Phoenix, Atlanta, Charlotte |
| High-cost / high PTR | 7–10 years | Denver, Seattle, Miami, Washington DC |
| Very high-cost / extreme PTR | 10–15+ years | NYC, SF, LA, Boston, San Diego |
Price-to-rent ratio = home price ÷ annual rent. Under 15 favors buying; over 20 favors renting. San Francisco’s PTR is approximately 30–35; Cleveland’s is around 10–12.
Why Early Mortgage Payments Are Mostly Interest
A major reason the break-even takes years is that early mortgage payments are almost entirely interest — not principal. On a $338,000 mortgage (after 20% down on a $422,000 home) at 6.8% for 30 years:
| Year | Cumulative Principal Paid | Cumulative Interest Paid | Remaining Mortgage |
|---|---|---|---|
| 1 | $4,100 | $22,700 | $333,900 |
| 3 | $12,700 | $66,900 | $325,300 |
| 5 | $22,400 | $109,800 | $315,600 |
| 10 | $51,200 | $211,700 | $286,800 |
| 15 | $91,500 | $299,600 | $246,500 |
| 30 | $338,000 | $384,000 | $0 |
In year one, you pay $22,700 in interest to keep only $4,100 in principal. That $22,700 is gone — similar in that sense to rent. The equity story only becomes compelling at years 7–10 when principal paydown accelerates and appreciation compounds.
The Down Payment Opportunity Cost — A Number Most Calculators Ignore
If you put $84,400 down on a $422,000 home (20%), that money could otherwise grow in a diversified stock index fund. At a 7% annual return, that $84,400 becomes:
| Years | Value of Invested Down Payment |
|---|---|
| 5 | $118,300 |
| 10 | $165,900 |
| 15 | $232,600 |
| 20 | $326,000 |
This is not money you “lose” by renting — it’s opportunity cost. The rent-vs-buy decision is really a comparison between building equity in real estate vs. building wealth in financial markets. Both are legitimate paths to long-term wealth; which is better depends on appreciation rates, your local market, and time horizon.
Renting vs. Buying: Non-Financial Factors
The calculator measures financial cost, but the decision also involves factors money can’t fully quantify:
Reasons to buy even if the math is close:
- Stability for school districts and community roots
- Freedom to renovate, own pets, paint walls
- Forced savings discipline (mortgage as “savings plan”)
- Protection from rent hikes and lease non-renewals
- Potential long-term inflation hedge
Reasons to rent even if buying looks cheaper:
- Job or life uncertainty (relocation risk)
- High-cost market where renting is substantially cheaper
- Limited savings for a meaningful down payment
- Avoiding maintenance and repair responsibility
- Capital available for higher-return investments
2026 Market Context: Why Renting Looks More Attractive Than Usual
The combination of high home prices and elevated mortgage rates has pushed the monthly cost of buying to historical highs relative to renting. The mortgage affordability ratio — the share of median household income required to buy a median home — reached approximately 42% in 2026, well above the historical average of 25–30%.
This is why more analysts than usual are recommending renting-and-investing in 2026, particularly for buyers with short (under 7 year) time horizons. The break-even year has lengthened compared to 2019–2020 in most markets due to the rate environment.
For buyers with longer horizons (10+ years), the math still tends to favor buying in most non-coastal markets, because appreciation and forced savings compound significantly over time.
Frequently Asked Questions
How does the calculator handle property taxes?
Property tax is entered as an annual percentage of home value. The national average is 1.09%, but it ranges from 0.27% in Hawaii to 2.49% in New Jersey. You can find your county’s rate on your local assessor’s website or on property tax by state data. The calculator applies this rate to the appreciating home value, so your modeled tax burden grows over time.
Is the 3% buying closing cost assumption accurate?
Buying closing costs typically run 2–5% of the home price, covering lender origination fees, title insurance, appraisal, and prepaid expenses. The calculator uses 3% as a reasonable midpoint. Selling costs (6%) cover agent commissions (historically 5–6%) plus title and recording fees. These are among the largest drivers of the break-even period.
What if I get a tax deduction on mortgage interest?
The mortgage interest deduction benefits roughly 10–15% of taxpayers who itemize deductions. If you itemize, your federal taxable income is reduced by mortgage interest paid — worth approximately 22–24 cents per dollar for most homeowners in higher brackets. This isn’t modeled in the calculator to keep it simple, but it would slightly favor buying in years when interest is high (early in the mortgage).
Should I include PMI if my down payment is under 20%?
If you put less than 20% down on a conventional loan, you’ll pay private mortgage insurance (PMI) — typically 0.5–1.5% of the loan amount annually. That adds $150–$450/month on a $360,000 loan. PMI is automatically cancelled once you reach 20% equity. For the most accurate result with a low down payment, add your estimated PMI to the annual insurance input.
