About the House Affordability Calculator

good long-tail opportunity

The House Affordability Calculator is a free online financial tool designed to help you estimate how much house you can afford based on your income, existing debts, down payment, and local housing costs. If you already have a specific home price in mind, pair this with our Mortgage Calculator for a full monthly payment breakdown including taxes, insurance, and PMI.

This tool uses the standard 28/36 debt-to-income rule to compute your maximum affordable home price. You can adjust annual income, monthly debts, down payment (percentage or dollar amount), interest rate, loan term (15/20/30 years), property tax, home insurance, HOA fees, and PMI (automatically enabled when down payment is under 20%). The results show your max home price, max loan amount, front-end and back-end DTI ratios, and a full monthly payment breakdown. A scenario comparison table lets you test up to three alternative rate and term combinations to find the best buying power.

Formulas & Mathematical Theory

Front-End DTI (Housing Ratio)

DTIfront=Total Monthly Housing CostsGross Monthly Income×100%\text{DTI}_{\text{front}} = \frac{\text{Total Monthly Housing Costs}}{\text{Gross Monthly Income}} \times 100\%

Compares total housing costs (principal, interest, taxes, insurance, HOA) to gross monthly income. Lenders typically cap this at 28% for conventional loans.

Maximum Affordable Home Price

Pmax=Affordable Monthly Payment×((1+r)n1)r×(1+r)n+Down PaymentP_{\text{max}} = \frac{\text{Affordable Monthly Payment} \times \left((1+r)^n - 1\right)}{r \times (1+r)^n} + \text{Down Payment}

Derives the maximum home price by solving the mortgage payment formula for principal, then adding the down payment.
