What is a Home Affordability Calculator?

A home affordability calculator determines how much house you can afford based on your income, debts, down payment, and current interest rates. It uses standard lending guidelines to estimate a realistic price range that fits your budget.

Formula:

Max Home Price = (Monthly Income × 0.28) / Monthly Payment Factor

Lenders typically require housing costs to be no more than 28% of gross monthly income (front-end ratio).
