2. How Does the Calculator Work?

The calculator uses the 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 required to fully amortize the loan over its term.
