1. What is APR?

APR (Annual Percentage Rate) represents the true cost of borrowing money, including both interest charges and fees. It's expressed as a yearly percentage and allows consumers to compare different credit offers on an equal basis.

2. How Does the Calculator Work?

The calculator uses the standard APR formula:

\[ APR = \frac{(Total\ Interest + Fees)}{P} \times \frac{365}{T} \times 100 \]

Where:

\( Total\ Interest \) — Total interest paid over the loan term
\( Fees \) — Any additional fees charged by the lender
\( P \) — Principal loan amount
\( T \) — Loan term in days

Explanation: The formula calculates the annualized cost of credit by considering both interest and fees relative to the principal amount over the specified time period.

3. Importance of APR Calculation

Details: Understanding APR is crucial for making informed financial decisions. It helps consumers compare different credit card offers and understand the true cost of borrowing, enabling better financial planning and debt management.

4. Using the Calculator

Tips: Enter all amounts in currency format, ensure the principal amount is greater than zero, and the loan term is at least one day. The calculator will provide the APR as a percentage.
