How lenders in the United States assess affordability

  • The Consumer Financial Protection Bureau suggests homeowners consider keeping mortgage payments at 28–35% of gross income or less, and all debt payments at 36% or less. It presents these as planning benchmarks, not lending rules.

  • Lenders look at your debt-to-income ratio: all monthly debt payments divided by gross monthly income. Different loan products and lenders use different limits.

OwnerCost uses 28% of gross income — the low end of the CFPB range — as its planning ceiling for the full monthly owner cost. It is an OwnerCost planning assumption, not a lender or regulatory limit.

How we calculate

We search for the highest price at which principal and interest, property tax, insurance and PMI equal 28% of gross monthly income (OwnerCost's planning ceiling), using your down payment percentage and rate. Monthly rate = quoted annual rate ÷ 12. Payment = P·i / (1 − (1 + i)^−n) over n months.
