What is the Rent vs Buy Calculator?
Compare buying a home with renting and investing the difference over time.
Each year the buyer pays the mortgage, property tax, insurance and maintenance while the home grows in value; selling costs are deducted at the end. The renter invests the upfront cash and any monthly cost difference at your return rate, and rent rises yearly. Final net worth for each path is compared.
Borrowing is easier to judge once you can see the real cost: the monthly payment, the total interest and how long it takes to be free of the debt.

Tips for better results
The result is very sensitive to home price growth and investment return, so test optimistic and cautious values. Staying longer usually favors buying because upfront costs are spread out.
Compare offers using the total cost, not just the monthly payment.
Even a small extra payment each month can shorten the term noticeably.

Frequently asked questions

No. It ignores mortgage interest deductions and other tax effects, which differ by place and person.
Why does the time horizon change the winner?

Is the rent vs buy calculator free?
Yes. It is free to use with no signup, no watermark and no usage limits.
