Mortgage affordability calculator

Estimate a home-price scenario from income, debt, recurring ownership costs and adjustable debt-to-income assumptions. This is not a lender approval or prequalification.

Transparent assumptions
The starting 28% housing and 36% total-debt ratios are editable planning inputs, not universal lending limits.

Change every assumption to match your own planning case. The calculation does not evaluate credit, cash reserves, lender overlays, mortgage insurance, closing costs, utilities or maintenance.

How it works

The tighter budget controls the estimate.

The tool calculates a housing budget under both editable ratios, subtracts recurring tax, insurance and HOA costs, then reverses the fixed-rate annuity formula to estimate principal. Negative budgets are floored at zero.
