1. What is Simple Interest?

Simple interest is a method of calculating interest where the interest amount is computed only on the original principal amount throughout the loan term. It's commonly used for short-term loans and student loans.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( Principal \) — Original loan amount
• \( Rate \) — Annual interest rate (as a decimal)
• \( Time \) — Loan duration in years

Explanation: The formula calculates how much interest will accrue over the life of the loan based on the principal amount, annual rate, and time period.

3. Importance of Interest Calculation

Details: Understanding loan interest helps borrowers plan repayment strategies, compare loan options, and make informed financial decisions about their education financing.

4. Using the Calculator

Tips: Enter the loan principal in dollars, interest rate as a percentage (e.g., 5.5 for 5.5%), and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q4: Are student loan interest rates fixed or variable?
A: Federal student loans have fixed rates, while private loans may be fixed or variable. Check your specific loan terms.
