How the house affordability calculator works

Income mode applies both limits: housing payment ≤ gross monthly income × front-end target, and housing payment + monthly debts ≤ gross monthly income × back-end target. Budget mode uses the entered monthly limit.

The solved payment includes principal and interest, property tax, homeowners insurance, HOA fees, and estimated PMI when the down payment is below 20%.

How to use this calculator

  1. Choose income and debts or a monthly housing budget.
  2. Enter the mortgage and down-payment assumptions you want to compare.
  3. Review the maximum price, full payment breakdown, DTI ratios, and estimated cash needed.

Worked example

Example: $120,000 income and $1,000 of monthly debt

With $10,000 gross monthly income, 28% front-end and 36% back-end targets allow up to $2,800 or $2,600 respectively for housing.

With a $50,000 down payment, a 0% 120-month example loan, and no added ownership costs, the tighter back-end limit supports an estimated $362,000 home price.
