1. What is the Federal Student Loan Payment Formula?

The federal student loan payment formula calculates the fixed monthly payment required to repay a loan over a specified term. It accounts for the principal amount, interest rate, and loan duration.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

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

Explanation: The formula calculates the fixed payment needed to fully amortize the loan over its term, with each payment covering both principal and interest.

3. Importance of Loan Payment Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. Federal student loan rates start at 5.50% for unsubsidized loans (2025 rates).

4. Using the Calculator

Tips: Enter the principal amount in USD, annual interest rate as a percentage (e.g., 5.50), and loan term in years. All values must be positive numbers.
