Buy vs Rent Break-Even Calculator

How to Use This Calculator

Enter the home purchase price, down payment, mortgage terms, ownership costs, expected home appreciation, selling costs, current monthly rent, expected rent growth, and the return you could earn by investing the cash used for the down payment and purchase closing costs. The calculator compares the estimated economic cost of buying and renting over a selected time horizon.

Formula & Methodology

The calculator compares unrecoverable housing costs rather than simply comparing rent with a mortgage payment. For buying, it estimates mortgage interest, property tax, insurance, maintenance, HOA fees, purchase closing costs, eventual selling costs, and the opportunity cost of upfront cash, while recognizing home appreciation and mortgage principal reduction as wealth-building effects rather than expenses. Renting includes cumulative rent with annual increases and renter insurance while allowing the upfront cash that would have been used to buy to remain invested. The break-even point is the earliest modeled year in which the estimated economic position from buying is at least as favorable as continuing to rent.

Example: $400,000 home versus $2,200 monthly rent

Suppose a $400,000 home is purchased with 20% down using a 30-year fixed mortgage, while an equivalent property rents for $2,200 per month. Buying may initially be disadvantaged by closing costs, property taxes, maintenance, and selling costs. Over time, mortgage principal is repaid and the home may appreciate, while rent can increase annually. The break-even result estimates the first year when those cumulative effects make buying economically competitive with renting under the assumptions entered.

Frequently Asked Questions

How do you calculate the break-even point between buying and renting?

Compare the cumulative economic costs and wealth effects of both choices over time. Buying includes transaction costs, mortgage interest, property taxes, insurance, maintenance, HOA fees, selling costs, home appreciation, and mortgage principal repayment. Renting includes rent increases and the potential investment return on cash that would otherwise be used for the purchase.

Why is comparing rent with the mortgage payment not enough?

A mortgage payment includes principal repayment, which builds home equity and is not purely an expense. Homeowners also pay taxes, insurance, maintenance, HOA fees, interest, and transaction costs. Renters may instead invest money that would have been used for a down payment.

What is the opportunity cost of a down payment?

The opportunity cost is the potential investment growth you give up by putting cash into a home rather than leaving that money invested elsewhere. This calculator estimates that alternative growth using the investment return you enter.

Does home appreciation affect the buy-versus-rent result?

Yes. Expected appreciation can materially improve the buying scenario because it increases the estimated future value of the home. Appreciation is uncertain, so it is useful to test conservative, base, and optimistic assumptions.

Why are selling costs included?

Buying may look attractive if you ignore the cost of eventually selling the property. Agent commissions, transfer costs, concessions, and other expenses can consume a meaningful portion of the home's value, particularly over short holding periods.

Does the calculator include maintenance?

Yes. Annual maintenance is estimated as a percentage of the home's value. Actual costs can vary considerably by property age, condition, location, and major repairs.

Does the calculator include HOA fees?

Yes. Monthly HOA fees can be entered separately and are included in the estimated ownership cost.

How are future rent increases calculated?

The calculator compounds the current annual rent by the expected annual rent growth rate over the selected holding period.

What does a positive buy advantage mean?

A positive buy advantage means the modeled economic position from buying is better than renting by that amount at the selected time horizon. A negative value indicates that renting is favored under the assumptions entered.

How long should I plan to stay before buying makes sense?

There is no universal minimum. The answer depends on transaction costs, mortgage rate, home appreciation, rent, rent growth, maintenance, taxes, investment returns, and other assumptions. The estimated break-even year helps evaluate your specific scenario.
