Rent vs Buy Calculator

Blake Boege
Written by Blake Boege · Founder, Calculator Answers

A rent vs buy calculator is a housing finance utility that compares the total costs of renting a home against purchasing one over a specified time horizon. The calculator models expenses such as monthly rent, rental insurance, home purchase price, down payment, mortgage payments, property taxes, maintenance, home insurance, and expected property appreciation. It computes the net financial difference between the two choices, helping users identify the transition point where buying becomes more cost-effective than renting.

Enter rent details and purchase details with a time horizon. The calculator estimates total out-of-pocket cost on each side, subtracts net sale proceeds on the buy side, and shows which is cheaper over your horizon.

This is a directional comparison with many assumptions. Results swing with appreciation, rent growth, and how long you stay. The actual best answer for you depends on personal factors this calculator does not capture.

Rent vs buy

Buying is cheaper over horizon

$43,183.03

Over 7 years, with the assumptions you entered

Total rent cost$203,549.00
Buy out-of-pocket$315,383.31
Home value at end$491,949.55
Loan balance at end$307,415.23
Selling cost$29,516.97
Net sale proceeds$155,017.34
Net buy cost (after sale)$160,365.97
Difference (buy − rent)−$43,183.03

Directional estimate. Sensitive to assumptions: appreciation, rent growth, time horizon, maintenance %, and selling cost all move the answer. Renting includes flexibility benefits this calculator does not quantify; buying includes stability, customization, and tax considerations it also does not quantify.

Examples

$2,200 rent, $400k home, 7 yr, 6.5% rate

depends on appreciation; often close to even

$2,200 rent, 3% growth · $400k, 1% appr, 7 yr

rent often wins

$2,200 rent, 3% growth · $400k, 4% appr, 15 yr

buy often wins

How it works

Rent side adds 12 months of rent each year, growing by the annual increase. Buy side adds principal & interest, an annual property tax (on current home value), monthly home insurance, annual maintenance percent of home value, and HOA dues. Home value grows by the appreciation rate. At the end of the horizon, the calculator estimates sale proceeds (home value − loan balance − selling cost) and subtracts that from total out-of-pocket to get net buy cost.

Total rent · Σ rent × 12 + renter ins, with annual rent growth

Total buy out-of-pocket · down + Σ (P&I + tax + ins + maint + HOA)

Net sale · home value − loan balance − selling cost

Net buy cost = total out-of-pocket − net sale. Difference = net buy cost − total rent.

Note. Rent vs buy is famously assumption-heavy. The calculator does not model investment opportunity cost of the down payment, tax benefits, PMI, lender fees rolled into closing, or the non-financial value of either option. Use it for directional thinking, not a verdict.

Frequently asked questions

No. The right answer depends on how long you'll stay, local rent vs price ratios, mortgage rates, appreciation, and your personal situation. Short stays generally favor renting due to transaction costs on buying and selling. Longer stays often favor buying as equity builds and mortgage interest tilts toward principal.

Time horizon, appreciation rate, and rent growth rate move the result the most. A 1 percentage point change in appreciation over 7 to 10 years can flip the answer either way. Maintenance and selling cost percentages also matter. The calculator surfaces every assumption so you can stress-test them.

No. The down payment could otherwise be invested for returns; that opportunity cost is real but hard to model honestly across markets. The calculator gives a straightforward out-of-pocket comparison so you can decide how to weight opportunity cost separately. Generally, higher expected investment returns make renting+investing look better.

Not modeled. Mortgage interest and property tax can be deductible if you itemize, but most filers take the standard deduction. Tax benefits also depend on jurisdiction (federal + state). For most middle-income filers, tax benefits are smaller than commonly assumed; for higher incomes in high-tax areas they can matter more.

Selling a home typically costs 5 to 7 percent of the sale price (agent commissions, closing costs, repairs, transfer taxes). On a $400k home that is $20k to $28k, paid from sale proceeds. If you sell soon after buying, this cost is a large share of any equity gained. Short horizons + selling costs = renting often wins.

Closing costs at purchase (2 to 5 percent of price) are real and usually paid in cash on top of the down payment. This calculator does not split them out, but you can add them to the down payment field to fold them in. Selling cost at the end of the horizon is modeled.
