Rent vs Buy Calculator — The True Financial Comparison for US Homebuyers

The rent vs buy decision is one of the most important financial choices an American family makes. With median US home prices around $400,000–$420,000 and mortgage rates between 6%–8%, the monthly cost of buying often significantly exceeds renting — yet buying builds equity and offers long-term appreciation. This calculator goes beyond just comparing monthly payments to show the true 5, 10, and 20-year financial outcome of each path.

The answer is not universal — it depends on how long you plan to stay, local home prices vs rents, mortgage rates, and what you'd do with the down payment if you rented instead. In high-cost cities like San Francisco and New York, renting and investing the difference often wins financially. In more affordable markets like Columbus or Kansas City, buying frequently wins within 4–5 years.

What is Rent vs Buy Analysis?

Rent vs buy analysis compares the total financial cost of renting a home against owning one over a specific time horizon, accounting for all costs, tax benefits, equity buildup, and the opportunity cost of the down payment. It is the foundational decision framework for US homebuyers.

The true cost of buying includes: down payment, closing costs (2%–5% of purchase price), monthly mortgage payment (principal + interest + property tax + insurance + HOA), and maintenance (typically 1%–2% of home value annually). Many buyers underestimate the non-mortgage costs.
The true cost of renting includes: monthly rent, renter's insurance (~$15–$30/month), and annual rent increases (national average ~3%–5% per year). Renters keep their down payment invested — the investment return on that capital is the "opportunity cost" that favors renting.
The mortgage interest deduction allows homeowners who itemize to deduct interest on up to $750,000 of mortgage debt (loans after Dec 15, 2017). However, the 2017 Tax Cuts and Jobs Act doubled the standard deduction, meaning fewer homeowners benefit from itemizing. Only about 14% of US taxpayers now itemize.
The break-even point — when buying becomes cheaper than renting — typically ranges from 3 to 7 years in most US markets. If you plan to stay shorter than the break-even, renting is usually the better financial choice.

Rent vs Buy Comparison Framework

Total Cost of Buying = Down payment + Closing costs + Mortgage payments + Annual costs − Home equity at sale

Total Cost of Renting = Total rent paid − Investment growth on down payment
Break-even point = Year when cumulative buying cost < cumulative renting cost
Example: $400,000 home, 20% down ($80,000), 7% mortgage, 30-year term
Monthly mortgage (P&I) ≈ $2,129 + property tax ~$370 + insurance ~$150 = ~$2,650/month
vs comparable rent: $2,200/month → buying costs $450/month more initially
Break-even: approximately 5–7 years with 3.5% annual appreciation

Key Terms

Down Payment: The upfront cash payment toward the home purchase, typically 3%–20% of the purchase price. Putting less than 20% down requires Private Mortgage Insurance (PMI), adding $100–$300/month until you reach 20% equity. A 20% down payment on a $400,000 home is $80,000 — this is the opportunity cost capital if you rent instead.
Closing Costs: One-time fees paid at purchase, typically 2%–5% of the purchase price. On a $400,000 home, that's $8,000–$20,000. Includes lender origination fees, appraisal, title insurance, escrow, and prepaid taxes/insurance. These costs must be recouped before buying "breaks even" with renting.
PMI (Private Mortgage Insurance): Required by lenders when your down payment is less than 20%. PMI costs 0.5%–1.5% of the loan amount annually ($100–$300/month on a $300,000 loan) and can be cancelled once you reach 20% equity. FHA loans require mortgage insurance for the life of the loan regardless of equity.
Property Tax: An annual tax on real property assessed by local governments. The US average is about 1.1% of home value per year, but varies widely — from 0.27% in Hawaii to 2.4% in New Jersey. On a $400,000 home, the national average property tax is about $4,400/year ($367/month).
Opportunity Cost: The return you forgo by using your down payment to buy instead of investing. If you put $80,000 down on a home, that $80,000 could have grown in the stock market at ~7%/year to ~$305,000 in 20 years. This is the "hidden cost" of homeownership that most buyers don't factor in.
Home Equity: The portion of the home you own outright — current market value minus remaining mortgage balance. Equity grows through principal paydown and appreciation. After 30 years on a $400,000 home with 3.5% annual appreciation, your home may be worth ~$793,000 with zero mortgage — all equity.

Tips for US Home Buyers

Plan to stay at least 5 years — buying costs (closing costs + transaction costs when selling) take years to recoup. If you move in 2–3 years, renting is almost always cheaper.
Factor in all homeownership costs — mortgage is just the start. Property tax, insurance, HOA, and maintenance (budget 1%–2% of home value/year) add $500–$1,500/month on a $400,000 home.
Don't forget PMI — if your down payment is under 20%, PMI adds $100–$300/month until you hit 20% equity. Factor this into your true monthly cost.
The mortgage interest deduction is smaller than you think — after the 2017 tax reform doubled the standard deduction, most homeowners no longer benefit from itemizing. Don't count on a large tax break unless you have a very large mortgage.
Compare price-to-rent ratio — divide the home price by annual rent for a comparable unit. Below 15 generally favors buying; above 20 generally favors renting. NYC and SF often hit 30–40+, heavily favoring renting.
Model the opportunity cost — if you have an $80,000 down payment, calculate what it would grow to if invested in an S&P 500 index fund at 7% over your time horizon. This is the true comparison against home equity.

Frequently Asked Questions

It depends heavily on your local market and time horizon. With mortgage rates at 6%–7% and elevated home prices, monthly buying costs significantly exceed renting in most US markets as of 2024. However, if you plan to stay 7+ years, buying still builds substantial equity and appreciation. In affordable markets (Midwest, Southeast), buying often makes sense within 4–5 years. In high-cost coastal cities (NYC, SF, LA, Seattle), renting and investing the difference frequently wins financially unless you plan to stay 10+ years.

The price-to-rent ratio = home price ÷ annual rent for a comparable unit. Generally: below 15 favors buying, 15–20 is neutral, above 20 favors renting. Examples: a $300,000 home renting for $2,000/month has a ratio of 12.5 (buy-favorable). A $1,200,000 condo renting for $3,500/month has a ratio of 28.6 (strongly rent-favorable). US city averages range from 10–12 in affordable Midwest markets to 30–45 in San Francisco and Manhattan.

The break-even period varies significantly by market. In affordable US markets, break-even can be 3–5 years. In expensive coastal markets with high price-to-rent ratios, it can be 10–15 years or never. Closing costs alone (2%–5% of purchase price) take 2–4 years to recoup. The general rule: if you plan to stay fewer than 5 years, renting is usually the safer financial choice. Use this calculator with your specific numbers for an accurate break-even estimate.

Less than most people think. The 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction ($29,200 for married filing jointly in 2024), so only about 14% of US taxpayers now itemize. You only benefit from the mortgage interest deduction if your total itemized deductions exceed the standard deduction. For a $300,000 mortgage at 7%, year-1 interest is about $20,800 — you'd need $8,400+ in other deductions (state/local taxes up to $10,000 cap, charitable donations) to benefit from itemizing.

It's one of the biggest hidden costs of buying. An $80,000 down payment invested in the S&P 500 at 7% annual return grows to approximately $155,000 in 10 years and $305,000 in 20 years. If your home only appreciates 3%–4% annually, the invested down payment often grows faster than the equity benefit. However, leverage (borrowing 80% to buy) amplifies your return on equity — if a $400,000 home appreciates to $600,000, your $80,000 down payment effectively earned a 250% return.

Possibly — if you plan to stay long enough and the market has reasonable appreciation. Paying more monthly to buy can still be worth it because: (1) part of each payment builds equity (forced savings), (2) your mortgage payment is fixed while rent increases annually, (3) appreciation multiplies your invested equity, and (4) homeownership provides stability and control. The key question is the time horizon. If you plan to stay 7+ years in a market with 3%+ annual appreciation, buying often wins despite higher initial monthly costs.
