1. What is the Student Loan Payment Formula?

The student loan payment formula calculates the fixed monthly payment required to repay a loan over a specified term. This calculator uses standard federal student loan rates for the 2024-25 FAFSA cycle, starting at 5.50%.

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 compound interest over the life of the loan, calculating a fixed payment that covers both principal and interest.

3. Importance of Loan Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. Federal student loans for 2024-25 have fixed interest rates starting at 5.50% for undergraduate loans.
