The mortgage payment is the part everyone calculates and the part that matters least. Property taxes, insurance, PMI, and maintenance often add 50-80% on top. Our calculator gives you the full PITI + maintenance picture and projects equity growth over your expected hold period.
Enter price, down payment, rate, and ZIP-tier defaults for property tax and insurance. We surface the all-in monthly cost, the break-even hold period vs renting, and the equity you'll have at sale.

Frequently asked questions
How does this differ from your Rent vs Buy calculator?+
This focuses on the all-in cost of ownership and what you'll have at sale. Rent vs Buy compares both options head-to-head, including the opportunity cost of investing the down payment instead.
What maintenance percentage should I use?+
The default is 1% of home value annually, which is a reasonable long-run average. Older homes, custom finishes, and certain regions can push it to 2%+.
Does this account for the mortgage interest deduction?+
Most filers take the standard deduction post-TCJA, so we default to "no benefit." You can toggle on itemization to model the deduction.
