1. What is a Mortgage Calculator?

Definition: This calculator estimates the monthly payment for a fixed-rate mortgage based on the loan amount, interest rate, and loan term.

Purpose: It helps home buyers understand their potential mortgage payments and budget accordingly when purchasing real estate.

2. How Does the Calculator Work?

The calculator uses the standard mortgage formula:

Where:

• \( M \) — Monthly mortgage payment ($)
• \( P \) — Principal loan amount ($)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Number of payments (loan term in years × 12)

Explanation: The formula calculates the fixed payment amount that will pay off the loan balance with interest over the specified term.

3. Importance of Mortgage Calculation
