1. What is the PMT Formula?

The PMT (Payment) formula calculates the fixed periodic payment required to pay off a loan over a specified term, including both principal and interest components. It's widely used in mortgage and loan calculations.

2. How Does the Calculator Work?

The calculator uses the PMT formula:

Where:

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

Explanation: The formula calculates the fixed monthly payment needed to amortize a loan over the specified term, accounting for both principal repayment and interest charges.

3. Importance of Payment Calculation
