Rent vs. Buy Calculator

Compare the true cost of buying a home vs. renting and investing the difference. Includes opportunity cost, tax deductions, and appreciation.

The renter starts by investing the they didn't spend on a down payment and closing costs. Each month, they invest the difference between buying costs and rent. As rent increases % a year, this monthly advantage shrinks over time.

Net wealth over time

Buy = home equity − selling costs + investments. Rent = investments.

How reliable is this estimate?

()

This calculator compares net wealth from buying (home equity plus investments minus selling costs) vs. renting (invested savings, plus a delayed-purchase home if enabled). PMI is included when the down payment is under 20% (about 0.7% a year of the loan) and drops at 20% equity. Tax savings apply only when itemized deductions exceed the standard deduction. Property tax increases 2% a year. Actual results depend on market conditions, location, and personal circumstances. Not financial advice.

How it's calculated

We project the net wealth of renting vs. buying over your horizon, investing every dollar the rental scenario saves so the comparison is apples-to-apples.

Monthly mortgage payment
P × r(1 + r)n ÷ ((1 + r)n − 1)
True cost of owning
mortgage + property tax + insurance + HOA + maintenance + PMI
Tax savings
max(0, interest + property tax − standard deduction) × marginal rate
Rent scenario invests the gap
down payment + closing up front, then (owning cost − tax savings + owner's investing) − rent each month it is positive
Net wealth at year N
buy = home value × (1 − selling %) − loan balance + investments
rent = investment portfolio (+ the delayed home's equity − selling costs)
Tax-adjusted
net wealth − 15% × (portfolio − contributions)
  • Home appreciation, rent increase and investment return rates stay constant; investments compound monthly
  • Maintenance is a fixed percentage of home value a year; property tax grows 2% a year
  • Selling costs reduce sale proceeds
  • Tax savings apply only when itemizing beats the 2026 standard deduction ($16,100 single, $32,200 married filing jointly)
  • PMI at 0.7% a year of the loan if the down payment is under 20%, dropped at 20% equity
  • Once the mortgage is paid off the payment is redirected to investing, and the renter keeps investing against it
  • The renter is assumed to invest all monthly savings — in practice, many people spend it

Is it better to rent or buy?

There's no universal answer. Whether renting or buying is the better financial move depends on how long you plan to stay, your local price-to-rent ratio, current mortgage rates, what you'd otherwise do with your down payment, and how much you value flexibility versus the option to make a home truly yours.

Buying a home carries large upfront and ongoing costs that take real time to recoup. Closing costs, the opportunity cost of your down payment, and the front-loaded nature of mortgage interest mean the first few years of ownership build relatively little equity. The longer you stay, the more those one-time costs get amortized away.

The single biggest variable in almost every rent vs. buy decision is how long you'll stay. Buy for two years and the math rarely works; stay for ten and it usually does. That's why the break-even horizon — the point at which buying overtakes renting — is the metric this calculator centers on.

The true cost of buying a home

The mortgage payment is only part of the picture. Owning means a down payment (commonly 10–20% of the purchase price), closing costs (typically 2–5% of the loan), property taxes, homeowners insurance, ongoing maintenance, and HOA dues where they apply. A widely used rule of thumb budgets roughly 1% of the home's value per year for maintenance, though older homes and high-cost-of-living areas can run meaningfully higher.

Mortgage interest is also front-loaded. In the first several years of a 30-year loan, most of each payment goes to interest rather than principal, so equity builds slowly at first. And the cash you tie up in a down payment isn't free — its opportunity cost is whatever return that money would have earned if you'd invested it instead. A complete comparison has to count all of these, not just the monthly payment.

The true cost of renting

Renting is cleaner on paper: monthly rent plus a renters insurance policy, with no surprise capital expenses if the roof leaks or the HVAC dies. You get flexibility to move when a job, relationship, or city changes, and you don't pay closing costs or sell-side fees on your way out.

The tradeoff is that you build no equity in the property and you're exposed to rent increases over time. The honest financial comparison is "rent and invest the difference" — what your wealth looks like if the down payment, closing costs, and any monthly savings versus owning are consistently invested. Pair this calculator with a realistic monthly budget so the "difference" you're investing is one you'd actually save.

Understanding the break-even point

The break-even horizon is the number of years after which buying becomes cheaper than renting once you account for every cost on both sides — including the opportunity cost of the money you'd otherwise have invested. Stay shorter than the break-even point and renting usually wins; stay longer and ownership pulls ahead, often increasingly so as equity compounds.

The calculator above estimates your specific break-even from your inputs — purchase price, rent, interest rate, expected appreciation, and assumed investment return. Compare that number to how long you realistically expect to stay. If the break-even is 7 years and you'll likely move in 3, renting is probably the better financial call regardless of how the home market behaves.

Frequently asked questions

How long do I need to stay for buying to be worth it?

Most rent vs. buy comparisons land in the range of several years before buying overtakes renting, but the exact number depends heavily on your price-to-rent ratio, mortgage rate, closing costs, and assumed appreciation. The break-even horizon shown by this calculator is the right number to look at for your situation.

Is renting throwing money away?

No. Renting buys you flexibility and frees up capital you can invest. Buying also has costs that don't build equity — mortgage interest, property tax, insurance, maintenance, and transaction fees. The right framing isn't "rent vs. own"; it's "rent and invest the difference vs. own and build equity," and either can win depending on your numbers.

What upfront costs come with buying?

Down payment (typically 10–20% of the purchase price), closing costs (commonly 2–5% of the loan), prepaid property taxes and insurance, inspection and appraisal fees, and any immediate repairs or furnishings. It's reasonable to budget several thousand dollars beyond the down payment itself for everything else.

Should I invest my down payment instead?

That's the opportunity-cost question at the heart of rent vs. buy. A down payment locked into a house can't compound in a diversified portfolio, so the "right" choice depends on what you'd actually earn elsewhere and how long you'd stay. This is general information, not personalized financial advice.

Does buying always build wealth?

No. Wealth from a home depends on appreciation, how long you hold it, your interest rate, transaction costs on both sides, and ongoing carrying costs. In some markets and over short horizons, owners have ended up worse off than disciplined renters who invested the difference. It's a probability-weighted bet, not a guarantee.

What is the price-to-rent ratio?

Price-to-rent is the home's purchase price divided by the annual rent for a comparable property. As a rough rule, ratios under about 15 tend to favor buying, 15–20 is mixed, and above 20 tends to favor renting. It's a starting signal for whether a specific market leans rent or buy, not a final verdict.
