Can I use this calculator if I’m self-employed or have variable income?

The tool accepts any annual income figure you enter, but lenders typically require two years of tax documentation for self-employed applicants. Use the results as a starting point, not a final qualification.

What’s the difference between the two calculators on the page?

One estimates affordability based on your income and existing debts using standard DTI ratios; the other works backward from a monthly budget you specify, including taxes and maintenance costs.

Do I need to include a down payment to get a result?

You can enter a down payment as a dollar amount or percentage; if you leave it blank, the calculator will use a default percentage based on the selected loan type.

Are the loan ratio options (conventional, FHA, VA) binding?

No—they are standard guidelines that lenders commonly use to calculate debt-to-income limits. Your actual approved amount may vary based on your credit profile and the lender’s specific requirements.

What House Affordability Calculator does

The House Affordability Calculator on Calculator.net estimates how much house you can afford by running two separate calculators: one based on household income, debts, and down payment, and another based on a fixed monthly budget. The income-to-debt version factors in annual salary, mortgage term, interest rate, existing monthly debt obligations, down payment, and ongoing costs like property tax, HOA fees, and insurance to output a suggested purchase price. The budget version works in reverse, taking your monthly housing allowance plus tax, fees, and maintenance costs to determine the maximum home price you could target. Both versions apply standard U.S. lending ratios—conventional 28/36, FHA 31/43, and VA 41%—to frame the results. The site presents the math in a straightforward form layout with clear headings and default percentage options for common loan types, making it easy to compare scenarios without needing a financial advisor.
