How much house can I afford?
A home affordability calculator estimates the highest purchase price that fits your income, debts, down payment and monthly housing costs. This free calculator applies front-end and back-end debt-to-income limits, then works backward through the mortgage payment formula so you can see the home price, loan amount and monthly breakdown.
How to use
- 1Enter income and debts. Add your annual gross income and monthly recurring debt payments, such as car loans, student loans, credit cards or child support.
- 2Set your mortgage assumptions. Enter the down payment, interest rate and loan term. You can type the down payment as a fixed amount or as a percent.
- 3Add ownership costs. Estimate property tax, home insurance, HOA fees and PMI. These can materially change affordability, especially in high-tax areas.
- 4Read the limiting rule. The result shows the affordable home price, loan amount, monthly payment breakdown and whether the housing DTI or total DTI cap is the tighter constraint.
Who it's for
- First-time buyers checking a realistic price range before touring homes.
- Move-up buyers comparing a larger down payment against the monthly budget.
- Borrowers with debt seeing whether car, student or credit-card payments are the limiting factor.
- Couples planning a budget testing conservative 28/36 debt-to-income limits before talking to a lender.
- Home shoppers adjusting property tax, insurance, HOA and PMI assumptions for different neighborhoods.
FAQ
Is this home affordability calculator free?
Yes. It is free, has no sign-up and runs in your browser. Your income, debt and down payment numbers are not uploaded or stored by the calculator.
Is my financial information uploaded?
No. The calculation is done with client-side JavaScript on your device. The page does not need an account, and the figures you type into the calculator are not sent to a server.
What debt-to-income ratio should I use?
A common conservative starting point is 28% for housing costs and 36% for total debt payments. Some loan programs and lenders allow higher ratios, but a lower ratio usually leaves more room for repairs, utilities, savings and income changes.
Does this calculator include taxes, insurance, HOA and PMI?
Yes. The monthly payment breakdown includes principal and interest, estimated property tax, home insurance, HOA fees and PMI. Property tax is entered as an annual percent of the home price, while insurance is entered as a yearly amount.
Why does monthly debt reduce the affordable price?
The back-end DTI cap includes your housing payment plus recurring debts. A car payment, student loan or minimum credit-card payment uses part of that cap, leaving less monthly room for the mortgage and other housing costs.
Is the result a loan approval?
No. It is an estimate for planning. Lenders also review credit, assets, reserves, loan type, location, taxes, insurance, employment history and underwriting rules. Use this to set a budget before getting a real preapproval.
Which currency does it use?
No specific currency. Enter all money values in the same currency and read the output the same way. The page formats numbers for your language but does not add a currency symbol.
