1. What is the Mortgage Payment Formula?

The mortgage payment formula calculates the fixed monthly payment required to fully amortize a loan over its term. It accounts for both principal and interest payments, ensuring the loan is paid off by the end of the term.

2. How Does the Calculator Work?

The calculator uses the standard mortgage payment formula:

Where:

• \( P \) — Loan principal amount ($)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Total number of payments (term in years × 12)

Explanation: This formula calculates the fixed monthly payment that pays off the loan principal plus interest over the loan term.

3. Importance of Mortgage Calculation

Details: Accurate mortgage payment calculation is essential for budgeting, comparing loan offers, and understanding the total cost of homeownership over time.

4. Using the Calculator

Tips: Enter the loan amount in dollars, annual interest rate as a percentage, and loan term in years. All values must be positive numbers.
