Rent vs. Buy Calculator

Compare owning a home with renting and investing the difference: who comes out ahead, by how much, and the year buying pulls ahead.

Your comparison

Compare owning a home with renting and investing the difference in an S&P 500 index fund. Results update as you type.

Buying
The purchase price of the home.
Share of the price paid up front. The rest is the mortgage. 0% works too.
The fixed annual interest rate on the mortgage.
Length of the mortgage in years, usually 30 or 15.
years
Yearly property tax, upkeep and insurance as a share of the home’s value. 2–3% is typical: about 1% tax and 1% maintenance.
How fast the home’s value grows each year. U.S. home prices have risen roughly 3–4% a year over the long run, about inflation plus 1%.
Renting & investing
Rent for a comparable home today.
How much rent rises each year. It has tracked inflation plus a little, about 3–4%.
Expected annual return on the money the renter invests (and the buyer, when owning costs less than rent). The S&P 500 has returned about 10% a year with dividends; 7% is a cautious planning figure.
Comparison
How many years until you’d sell the home. The comparison is measured then, after selling costs.
years

More options closing and selling costs
Paid once when you buy, as a share of the price: lender fees, title, escrow. Usually 2–5%. The renter invests the same amount instead.
Paid when you sell, as a share of the sale price: agent commissions and transfer costs. Often 5–8%.

Is it better to rent or buy a home?

It depends on how long you stay and what your money would earn instead. Buying builds equity but costs interest, taxes, upkeep and big transaction fees; renting is flexible, and the down payment can be invested. Over short horizons renting usually wins; over long ones, buying often does.

“A $400,000 home with 20% down at 6.5%, or $2,200 rent with the difference invested at 7%. Who’s ahead after 7 years?”

Buying, narrowly: by about $4,256. Year 7 is the break-even year, the first year-end at which owning is ahead. Try this scenario

“Same home, but I might move in 3 years.”

Renting wins by about $22,204. Closing and selling costs swamp the equity a buyer builds in the first few years. Try this scenario

How does this rent vs. buy calculator work?

It follows two households month by month, spending the same cash. The buyer pays the mortgage, property tax and maintenance; the renter pays rent and invests the down payment and closing costs. Whoever’s monthly bill is lower invests the difference, so the comparison is fair.

Buying = home value − loan balance − selling costs + buyer’s investments · Renting = renter’s investments

Home value grows at your appreciation rate and investments at your market return. The break-even year is the first year-end at which buying is ahead. Taxes on investment gains and the mortgage interest deduction are left out; see the methodology.

“What if I stay 15 years?”

Buying wins by about $98,403. Each year of appreciation and principal paid compounds, while the renter’s rent keeps rising. Try this scenario

What is the price-to-rent ratio?

It’s the home price divided by a year of rent: $400,000 against $2,200 a month is about 15. Below roughly 15, buying tends to look attractive; above about 20, renting often wins. It’s a quick screen; this calculator adds financing, costs and returns.

“What if comparable rent is only $1,800 a month?”

Renting wins by about $42,931 after 7 years, and buying never catches up within 40 years at these returns. Try this scenario

How do mortgage rates and market returns change the answer?

A lower mortgage rate cuts the buyer’s monthly cost, so less money flows to the renter’s portfolio and buying wins sooner. A higher expected market return does the opposite: every dollar the renter invests grows faster. The two rates often decide the result more than the price does.

“Same 7-year plan at a 4% mortgage rate?”

Buying wins by about $71,220, and pulls ahead in year 3 instead of year 7. Try this scenario

“And if stocks return 10% a year instead of 7%?”

Renting wins by about $32,130, and buying never catches up within 40 years. Your market return is a key assumption, so test a cautious one. Try this scenario

Rent vs. buy FAQ

Does this include the mortgage interest deduction?

No. Since 2018 the higher standard deduction means most households don’t itemize, so the deduction often saves little or nothing. Taxes on the renter’s investment gains are also left out; home sale gains are largely tax-free for a primary residence. Both omissions roughly offset for typical buyers.

What costs of owning should I include?

Property tax (often around 1% of value a year), homeowners insurance, maintenance (a common rule is 1% of value a year) and HOA fees. Enter their total as a percentage of the home’s value. Closing and selling costs are separate, under More options.

Why does a short stay favor renting?

Buying has large one-time costs: around 3% to close and 6% to sell. In the first years most of each mortgage payment is interest, so little equity builds. It usually takes several years of appreciation and principal payments before owning recovers those costs.

What if I wouldn’t actually invest the difference?

Then buying looks better than this calculator shows. The comparison assumes the renter invests the down payment and every month’s savings. A mortgage forces saving through principal payments, which many people find easier to stick with than voluntary investing.
