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. This calculation is based on the principal amount, annual interest rate, and loan term.

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 accounts for both principal and interest payments over the life of the loan, resulting in a fixed monthly payment amount.

3. Importance of Loan Payment Calculation

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

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.
