Mortgage Affordability Calculator

Uses the 28/36 rule, the same guideline most mortgage lenders use, to estimate a realistic home price range based on your actual income and debts, not just what a lender says they'll approve.

How this works: your housing payment shouldn't exceed 28% of your gross monthly income (the "front-end" ratio), and your housing payment plus all other debt shouldn't exceed 36% (the "back-end" ratio). We calculate both and use whichever is more conservative.

Gross monthly income (before taxes)

Other monthly debt payments (car, student loans, credit cards, etc.)

Down payment

Estimated interest rate

Estimated monthly property tax & insurance

A rough monthly estimate is fine, this varies a lot by location.

The Mortgage Affordability Calculator is an educational estimate from Fit Finance Academy, not personalized financial or lending advice. The 28/36 rule is a common industry guideline, not a universal rule or a loan approval guarantee, actual lender requirements, rates, and loan programs vary. This is a starting point for conversation, not a guarantee, and it's not a substitute for advice from a qualified mortgage or financial professional.
