1. What Is APR?

APR (Annual Percentage Rate) is the annual rate charged for borrowing or earned through an investment. It represents the actual yearly cost of funds over the term of a loan, including any fees or additional costs associated with the transaction.

2. How Does The Calculator Work?

The calculator uses the standard APR formula:

\[ APR = \frac{Total\ Finance\ Charge}{Amount\ Financed} \times \frac{365}{Loan\ Term\ Days} \times 100 \]

Where:

\( Total\ Finance\ Charge \) — Total cost of borrowing including interest and fees
\( Amount\ Financed \) — Principal loan amount
\( Loan\ Term\ Days \) — Duration of the loan in days
\( 365 \) — Number of days in a year
\( 100 \) — Conversion to percentage

Explanation: This formula calculates the annualized cost of credit as a percentage, providing a standardized way to compare different loan offers.

3. Importance Of APR Calculation

Details: APR is crucial for consumers to understand the true cost of borrowing and compare different loan products effectively. It helps prevent misleading advertising by requiring lenders to disclose the full cost of credit.

4. Using The Calculator

Tips: Enter the total finance charge in dollars, the amount financed in dollars, and the loan term in days. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between APR and interest rate?
A: Interest rate is the cost of borrowing the principal amount, while APR includes the interest rate plus other charges like fees, making it a more comprehensive measure of loan cost.

Q2: Why is 365 days used in the formula?
A: 365 represents the number of days in a year, annualizing the rate to make it comparable across different loan terms.

Q3: What is considered a good APR?
A: A good APR depends on the loan type, credit score, and market conditions. Generally, lower APRs are better for borrowers.

Q4: Does APR include all loan costs?
A: APR includes most costs but may exclude some fees like late payment fees or returned check fees. Always review the loan agreement carefully.

Q5: How does loan term affect APR?
A: Longer loan terms typically result in higher total finance charges, which can increase the APR even if the interest rate remains the same.
