What is Annual Percentage Rate (APR)?
Annual Percentage Rate (APR) is the yearly cost of borrowing money or using credit, expressed as a percentage. It includes not just the interest rate but also fees, closing costs, and other charges associated with a loan.
APR is the total annual cost of credit, shown as a yearly percentage. It helps borrowers compare loan offers fairly because it includes interest plus fees, unlike the simple interest rate.

Step-by-step worked examples
A credit card has a 5% interest rate and $25 annual fee. If you borrow $1,000, what is the approximate APR?
Interest cost: 1000 × 0.05 = $50 Fee: $25 Total annual cost: 50 + 25 = $75 APR ≈ (75/1000) × 100 = 7.5%
A car loan of $20,000 at 4% interest includes $500 in fees. What is the APR?
Interest for 1 year: 20000 × 0.04 = $800 Fees: $500 Total annual cost: 800 + 500 = $1,300 APR ≈ (1300/20000) × 100 = 6.5%
Compare two credit cards: Card A (5% APR) vs Card B (3% interest + $50 fee). Same $2,000 balance.
Card A: APR = 5% = $100/year Card B: Interest = 2000 × 0.03 = $60 + Fee = $50 = $110/year Card A is better (lower APR).
