1. What is APR?

APR (Annual Percentage Rate) represents the annual cost of borrowing money, including interest and fees. It provides a standardized way to compare different loan offers and understand the true cost of credit.

2. How Does the Calculator Work?

The calculator uses the APR formula:

Where:

• \( PMT \) — Monthly payment amount ($)
• \( P \) — Principal loan amount ($)
• \( n \) — Number of monthly payments

Explanation: This formula calculates the annual percentage rate based on known monthly payment, principal amount, and loan term.

3. Importance of APR Calculation

Details: Understanding APR helps borrowers compare loan offers accurately, avoid predatory lending practices, and make informed financial decisions about credit products.

4. Using the Calculator

Tips: Enter the monthly payment amount in dollars, the principal loan amount in dollars, and the number of monthly payments. All values must be positive numbers.
