A rent vs buy calculator compares the long-term financial outcome of renting a home with buying a similar property. It needs more than a mortgage payment and a rent quote. Down payment, repairs, selling costs and the return on money you keep invested can change the answer.
Use the free calculator below to compare your own numbers, inspect the annual results and export them to Excel. Renting can be the stronger choice when ownership costs are high or your move-out date is close. Buying becomes more attractive when you stay long enough, can absorb repair bills and pay a reasonable price for the home.

Fixed-rate fully amortizing loan. Equal starting capital and monthly budgets; savings invested at month-end. Assumes full deposit refund. Excludes tax deductions, capital gains tax, refinancing and major improvements. Annual growth and investment returns are assumptions, not guarantees. No calculator data is sent to a server.
How to use the rent vs buy calculator
- Enter the home and financing costs. Include the purchase price, down payment, quoted interest rate and loan term. Use the note rate for principal-and-interest calculations, rather than APR.
- Add the costs your mortgage payment leaves out. Property taxes, homeowners insurance, maintenance, HOA dues and mortgage insurance belong in the ownership budget. Enter mortgage insurance and its expected duration yourself. The tool does not determine your cancellation eligibility.
- Enter the comparable rental. Add renters insurance, the refundable security deposit and any nonrefundable move-in fee. The first month of rent is already counted in the monthly schedule. Do not add it again as a fee.
- Set the time horizon and test assumptions. Run the years you realistically expect to stay. Then lower appreciation, raise maintenance or change rent growth. Select Calculate after editing, and use Export to Excel to save each scenario.
The Consumer Financial Protection Bureau’s homebuying cost guide explains why the list price leaves out borrowing fees and real estate costs. Use an actual Loan Estimate, local tax information and an insurance quote to replace estimates before making an offer.
Rent vs buy example: a $400,000 home and $2,200 rent
Consider a hypothetical $400,000 home with 20% down and a 30-year fixed mortgage at 6.5%. The loan is $320,000. Principal and interest are about $2,023 a month. That is below a $2,200 rental, but it is only part of the ownership bill.
| Cost | Buying | Renting |
|---|---|---|
| Principal and interest / rent | $2,023 | $2,200 |
| Property tax | $367 | Included in rent |
| Insurance | $150 | $20 |
| Maintenance budget | $333 | $0 separately modeled |
| Total monthly housing cost | $2,873 | $2,220 |
| Initial cash | $92,000 | $2,500 |
Buying initially costs about $653 more per month. It also requires $89,500 more cash upfront. The model gives the renter that initial cash difference to invest, then invests the monthly savings on whichever side has lower housing expenses. When buying becomes cheaper in a later month, the buyer gets that month’s savings instead. With the full default assumptions, including 3% annual appreciation and 5% investment returns, renting ends year seven approximately $8,152 ahead.
That distinction matters. Counting the buyer’s home equity while pretending the renter’s unused down payment disappears makes buying look better than a fair comparison would.
What the calculator measures
The headline result is the difference in ending wealth, assuming both households start with equal available cash and fund the same monthly budget. It includes a hypothetical sale at the end of each comparison year. A positive “buy advantage” favors buying. A negative number favors renting.
Buyer ending wealth = future home value − selling costs − remaining mortgage balance + invested monthly savings.
Renter ending wealth = invested initial cash difference + invested monthly savings + returned deposit.
Each investment account earns the same assumed after-tax, after-fee return. Contributions occur at month-end. Principal repayment reduces the loan balance; it is not counted twice as both investment income and equity. Down payment is cash committed to the purchase and later recovered only to the extent that net equity remains.
Home value compounds monthly from your annual assumption. Rent increases once a year. Property tax and maintenance use each year’s starting modeled home value, while insurance, HOA, renters insurance and other owner costs follow the separate annual cost-growth input. Real assessments and insurance renewals can behave differently.
When does buying break even?
The calculator reports the first modeled year-end when buying has at least as much ending wealth as renting. That is an annual checkpoint, not a precise monthly break-even date or a promise that buying stays ahead forever. Inspect the full table. Changing returns or costs can reverse an earlier lead.
Try a short holding period first. Purchase and sale costs have fewer years to spread across, so moving after two years can produce a very different answer from staying ten. Then run zero home appreciation. If the buying case needs strong price growth to work, you should know that before committing the deposit.
Also test a lower investment return. The renter’s modeled advantage assumes the savings are actually invested. Spending those savings produces a different household outcome.
Costs and risks the answer cannot settle
A maintenance allowance smooths spending into a monthly budget. A roof replacement arrives as a bill. Keep a separate emergency reserve and check whether the home needs known repairs; this model does not schedule major improvements or add their resale value.
Tax deductions, taxes on a sale, refinancing and changes in your income are excluded. No universal tax benefit is assumed. Add any unequal recurring owner expenses in the “other monthly owner costs” field. Unmodeled differences in utilities, parking or rental fees can otherwise distort the comparison.
A fixed mortgage does not freeze property taxes, insurance or association dues. Renting carries its own uncertainties, including renewal terms and the possibility of moving. Fannie Mae’s rent-versus-buy guide highlights the importance of both your expected stay and the responsibilities of ownership. A small modeled financial lead may matter less than a job move, accessibility needs or having enough cash left after closing.
Export your rent vs buy results to Excel
Select Export to Excel (.xlsx) after calculating. The workbook contains a summary, every input and annual results, including home value, loan balance, net sale equity and the two investment accounts. It is a genuine Excel workbook, not a CSV file renamed as Excel.
The export is a values-only snapshot. Editing a number inside that workbook will not recalculate it. Return to the online calculator, change the assumptions and export again. Your inputs and export are processed in your browser without a calculator account.
Buying a home to live in versus buying a rental
This calculator compares housing choices for an owner-occupant. It does not estimate a rental property’s investment return. If you plan to buy a property and lease it to someone else, use our rental property cash-on-cash return calculator to estimate annual cash flow relative to your cash investment. Use the DSCR calculator to assess income coverage of debt payments, then read how to calculate DSCR for a rental property.
Financing eligibility is a separate question. Our DSCR versus conventional investment-property loan guide explains those investment-loan differences. A business-purpose DSCR loan should not be assumed suitable for your personal residence.
Compare equal end dates: When you change the holding period, update selling costs, mortgage payoff and the renter’s alternative investment balance together. A five-year ownership result compared with a seven-year renting result isn’t a meaningful crossover point. Export a separate workbook for each horizon and keep all growth, cost and return assumptions visible beside it.
Frequently asked questions
Is renting always throwing money away?
No. Rent pays for housing and transfers many property ownership responsibilities to the landlord. Buying also has unrecoverable costs, including interest, taxes, insurance and transaction fees. Compare the full outcomes rather than treating every mortgage payment as savings.
Does a bigger down payment always make buying better?
No. It reduces the mortgage balance and interest cost, but commits more cash that could remain invested. Mortgage insurance and your emergency reserve can also change the decision. Recalculate the two scenarios using the same home price and time horizon.
Are these mortgage rates live?
No. The rate is an editable example. Enter your own lender quote. Our separate daily mortgage and DSCR benchmark panel provides dated context, but investment-loan advertised rates are not an owner-occupied mortgage offer.
Can I download the comparison in Excel format?
Yes. The export button creates a native .xlsx snapshot with assumptions, a summary and annual results. Change inputs in the online calculator and export again for a revised comparison.
Run your rent vs buy comparison using a realistic move-out date, then save a second Excel snapshot with less favorable assumptions. The gap between those scenarios tells you how much your decision depends on the forecast.
