- How this calculator works
How it works
Sample DTI caps limit housing (and total debt) payments. After other debts and tax/insurance/HOA, remaining room becomes maximum principal and interest, which reverse-amortizes into a loan and home price. Details: how we calculate.

How does this home affordability calculator work?
It applies sample front-end and back-end DTI caps you type to gross income, subtracts other debts and optional tax/insurance/HOA, then reverse-amortizes P&I into a max loan and home price. Sample: $80,000 income · 20% down · 6.5% · 30 years → about $280,165. Educational only.

No. Those are common teaching samples you can change. Lenders set their own guidelines; Nestfigure does not underwrite.
