1. What is a Home 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 homebuyers and homeowners understand their potential mortgage payments when using Zillow or other real estate platforms.

The calculator uses the standard mortgage formula:

Where:

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