Home Affordability Calculator

Affordability starts with monthly cash, not with a price tag. This calculator finds a housing budget from your income and existing debts, then subtracts the costs that come with owning a home. What remains is the amount available for a loan payment or rent.

Prefilled numbers are examples. Replace them with your own.

Your result appears here after you press Calculate.

How it is calculated

  • Budget by housing share = monthly gross income × housing share.
  • Budget by total debt share = monthly gross income × total debt share − existing monthly debts.
  • Monthly budget = the smaller of the two.
  • Left for loan or rent = budget − tax ÷ 12 − insurance ÷ 12 − HOA − utilities − upkeep.

Assumptions and limits

  • Prefilled numbers are examples for illustration. Replace them with quotes and prices from your own area.
  • The percentages are commonly cited planning guidelines, not requirements. Lenders set their own limits.
  • This tool stops at a monthly amount and does not convert it into a purchase price.
