Annual Percentage Rate (APR)
The annualized cost of borrowing money, including interest rates and upfront loan fees.
Plain-English Explanation
APR represents the true annual cost of a loan because it includes both the nominal interest rate and any upfront origination fees, closing costs, or points charged by the lender.
Mathematical Formula
APR = [ ((Interest + Fees) / Loan Principal) / Total Days ] * 365 * 100
Calculates total financial charges converted to an annual percentage rate.
Real-World Worked Example
A $10,000 personal loan with a 7% nominal interest rate and a $300 origination fee has an effective APR of approximately 8.35%.
Why Annual Percentage Rate (APR) Matters for Your Finances
APR enables accurate comparisons between competing loan offers that have different fee structures.
Common Misconception
Nominal interest rate only accounts for interest; APR reflects interest PLUS mandatory lender fees.
