1. What is Home Affordability?

Home affordability measures how much house you can afford based on your income and current interest rates. The standard guideline suggests spending no more than 28% of your gross monthly income on housing expenses.

2. How Does the Calculator Work?

The calculator uses the affordability formula:

Where:

• \( Income \) — Annual gross income in dollars
• \( Rate \) — Annual interest rate as decimal (e.g., 0.05 for 5%)
• 0.28 — Standard affordability ratio (28% of income)

Explanation: The equation calculates the maximum home price you can afford while keeping your monthly payment at 28% of your monthly income.

3. Importance of Affordability Calculation

Details: Calculating home affordability helps prevent overextending financially and ensures you can comfortably make mortgage payments while maintaining other financial obligations.

4. Using the Calculator

Tips: Enter your annual gross income in dollars and the current mortgage interest rate as a decimal (e.g., 0.04 for 4%). All values must be valid positive numbers.
