House Affordability Calculator
Estimate how much house you can afford based on income and debts.
Before house-hunting, it helps to know your realistic budget — not just what a lender might approve, but what fits comfortably against your income and existing debts. This estimates that ceiling using a standard debt-to-income guideline.
The 36% guideline, explained
Many lenders use a debt-to-income (DTI) ratio around 36% as a common benchmark — meaning your total monthly debt payments, including the new mortgage, shouldn't exceed roughly 36% of your gross monthly income. Some loan programs allow higher ratios, and some financial advisors recommend staying more conservative than 36%, especially in higher cost-of-living areas.
Approved amount vs. comfortable amount
A lender might approve you for more than what actually feels comfortable once you account for savings goals, other financial priorities, and unexpected costs of homeownership (maintenance, repairs, higher utility bills). Treat this estimate as a starting ceiling, not a target to max out.
Frequently asked questions
Does this account for property taxes and insurance?
Indirectly — the 36% guideline is meant to cover your full housing payment including estimated taxes and insurance, not just principal and interest, so the resulting home price estimate already has some built-in buffer for those costs.
Why does my other debt affect how much house I can afford?
Lenders look at your total monthly debt obligations, not just the new mortgage — a car payment or student loans reduce how much monthly payment you have "room" for under the same income, directly lowering your affordable home price.
