Introduction

Lenders evaluate gross income, existing debts, and housing costs to set approval limits. This calculator applies conventional, FHA, or VA debt-to-income guidelines—or works backward from a monthly payment you choose.

How Much House Can You Afford?

Lenders evaluate gross income, existing debts, and housing costs to set approval limits. This calculator applies conventional, FHA, or VA debt-to-income guidelines—or works backward from a monthly payment you choose.

Front-End vs Back-End DTI

Front-end DTI is housing payment divided by gross income. Back-end DTI includes housing plus other monthly debts (car loans, student loans, credit cards). Many conventional programs cap back-end DTI near 43-50% depending on compensating factors.

Taxes, Insurance, and Maintenance

Affordability is not just principal and interest. Property taxes, insurance, HOA dues, and maintenance reserves belong in your housing budget. Enable these fields to avoid overbuying based on P&I alone.

FHA and VA Guidelines

FHA loans allow higher DTI with compensating factors and lower down payments. VA loans for eligible veterans often have flexible DTI and no down payment. Select the program that matches your financing path.

Next Steps

After you know your max price, use the Down Payment Calculator and Mortgage Calculator. Compare renting with the Rent vs. Buy Calculator.
