Maximum-payment method
The calculator takes the lower of the housing-only cap and income-times-total-debt percentage minus other monthly debts. Tax, insurance, and HOA are subtracted before solving the fixed-rate payment formula backward for principal.
Not lender approval
Ratios are editable example assumptions. The estimate does not use credit scores, property data, current rates, lender rules, mortgage insurance, closing costs, or an underwriting decision.
Worked example
With $8,000 gross monthly income, $600 monthly debt, editable 28%/36% assumptions, and entered housing costs, the calculator uses the tighter payment cap before solving for mortgage principal.
Estimate boundaries
Results depend entirely on entered assumptions. They do not retrieve lender terms, approval decisions, issuer data, live rates, routes, fuel prices, or professional financial advice.
