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 homebuyers and homeowners understand their potential mortgage payments when purchasing or refinancing a home.

2. How Does the Calculator Work?

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)

Explanation: The formula calculates the fixed monthly payment that would be required to pay off the loan over its term, including both principal and interest.

3. Importance of Mortgage Calculation

Details: Understanding your mortgage payment helps with budgeting, comparing loan options, and determining how much house you can afford.

4. Using the Calculator
