Frequently Asked Questions
How does a rent vs buy calculator work?
A rent vs buy calculator compares the total cost of buying a home (mortgage, property tax, insurance, maintenance, closing costs) against renting over a multi-year horizon. It factors in home appreciation, equity built, and the opportunity cost of investing your down payment instead. The result is a break-even year where buying becomes cheaper than renting.
What is the break-even point for buying vs renting?
The break-even point is the year when cumulative buying costs drop below cumulative renting costs. Before that year, renting is cheaper. After it, buying wins because your mortgage payments build equity while rent keeps rising. This calculator shows the exact break-even year automatically.
Should I rent or buy a house calculator?
Enter your local home price, down payment, mortgage rate, monthly rent, and rent growth rate. The Summary Dashboard shows a clear verdict: whether buying or renting saves more over 30 years, and exactly which year buying pulls ahead. This home buying decision tool in Excel works offline with no internet required.
What costs does a rent vs buy calculator include?
Buying costs include purchase price, down payment, mortgage interest, closing costs, property tax, home insurance, maintenance, and HOA. Renting costs include monthly rent, renter's insurance, annual rent increases, and the opportunity cost of investing your down payment at an assumed return rate. This rent versus buy calculator includes every cost category so your comparison is complete.
Does this calculator account for investment opportunity cost?
Yes. If you rent instead of buy, your down payment stays invested. The calculator grows that down payment at an investment return rate you set on the Assumptions tab. This opportunity cost is added to the rent side of the comparison.
Can I use this rent vs buy calculator in Google Sheets?
