Understanding APR (Annual Percentage Rate)

Our APR Calculator helps you understand the true cost of borrowing by accounting for both the interest rate and any additional fees or charges. Below are explanations of key concepts and factors to consider when evaluating loan offers.

What is APR?

APR (Annual Percentage Rate) represents the true annual cost of borrowing money, including both the interest rate and any additional fees or charges associated with the loan. Unlike the simple interest rate, APR gives you a more complete picture of what you'll pay.

Key Differences Between APR and Interest Rate

Feature	Interest Rate	APR
Definition	Cost of borrowing principal	Total cost including fees
Includes Fees	No	Yes
Usefulness	Calculating monthly payments	Comparing loan offers
Typical Value	Lower than APR	Higher than interest rate

How APR is Calculated

The APR calculation uses the following formula:

APR = [(Fees + Total Interest) / (Loan Amount × Loan Term in Days)] × 365 × 100
Where:
- Fees include all upfront charges
- Total Interest is calculated over the loan term
- Loan Term in Days is converted from years/months

Factors That Affect APR

• Interest Rate: The base rate charged by the lender
• Origination Fees: Upfront charges for processing the loan
• Processing Fees: Administrative costs of setting up the loan
• Loan Term: Longer terms typically have higher APRs
• Payment Frequency: More frequent payments can slightly reduce APR
• Prepayment Penalties: Fees for paying off early increase APR

Why APR Matters

• Allows accurate comparison between different loan offers
• Reveals hidden costs not shown in the interest rate
• Helps identify the most cost-effective borrowing option
• Required by law to be disclosed by lenders (truth in lending)
• Better reflects the true cost of credit

Common Fees Included in APR

• Loan origination fees
• Processing fees
• Underwriting fees
• Document preparation fees
• Credit insurance (if required)
• Prepayment penalties
