APR Calculator

APR (Annual Percentage Rate) is the total yearly cost of borrowing, including the interest rate plus all fees and charges. While interest rate only reflects the cost of borrowing the principal, APR gives you the true cost. For example, a loan with 5% interest rate might have 5.5% APR after including origination fees, closing costs, and other charges.

APR is calculated by: 1) Adding all loan fees to the total interest paid over the loan term, 2) Dividing by the principal, 3) Dividing by the number of days in the loan term, 4) Multiplying by 365, then 5) Multiplying by 100 for a percentage. The formula accounts for the time value of money, making it more complex than simple interest calculations.

Good APRs vary by loan type and credit score. As of 2024: Mortgages: 6-7% (excellent credit), Credit cards: 15-20% (average), 10-15% (excellent). Personal loans: 8-12% (good credit). Auto loans: 5-7% (new cars, good credit). Always compare APRs from multiple lenders, as rates can vary by several percentage points.

Credit cards have high APRs (typically 15-25%) because they're unsecured debt with no collateral. The lender takes on more risk since they can't repossess anything if you default. Additionally, credit cards offer convenience features like rewards and purchase protections. However, you can avoid paying APR entirely by paying your full balance each month.

Fixed APR stays the same throughout the loan term, making payments predictable. Variable APR fluctuates based on an index rate (like the Prime Rate), meaning your payments can increase or decrease. Mortgages often offer both options; variable rates usually start lower but carry more risk if rates rise significantly.
