1. What is Personal Loan Interest?

The total interest on a personal loan represents the additional amount you pay beyond the principal borrowed. It's calculated based on your monthly payments, loan term, and principal amount.

2. How Does the Calculator Work?

The calculator uses the personal loan interest formula:

Where:

• \( PMT \) — Monthly payment amount (USD)
• \( n \) — Number of months in loan term
• \( PV \) — Principal loan amount (USD)

Explanation: The formula calculates the total amount paid over the loan term and subtracts the principal to determine the interest paid.

3. Importance of Interest Calculation

Details: Understanding total interest helps borrowers compare loan offers, assess affordability, and make informed financial decisions.

4. Using the Calculator

Tips: Enter your monthly payment amount, loan term in months, and principal amount. All values must be positive numbers.
