1. What is the Fannie Mae Loan Payment Formula?

The Fannie Mae standard loan payment formula calculates fixed monthly payments for student loans, whether under standard repayment plans or income-driven repayment plans. This formula is widely used in the student loan industry.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

\[ PMT = P \times \frac{r \times (1 + r)^n}{(1 + r)^n - 1} \]

Where:

\( P \) — Principal loan amount (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total number of payments (loan 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, calculating a fixed monthly payment that will pay off the loan in full by the end of the term.

3. Importance of Loan Payment Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. It allows borrowers to compare different loan terms and interest rates to find the most suitable repayment option.

4. Using the Calculator

Tips: Enter the principal amount in USD, annual interest rate as a percentage (e.g., 5.25), and loan term in years. All values must be positive numbers.
