The effective annual interest rate EAR , on the other hand, does account for intra-year compounding, which can occur on a daily, monthly or quarterly basis. Typically, the effective annual interest rate will lead to higher returns than the stated annual interest rate due to the power of compounding. Investors can compare products and calculate which type of interest will offer the most favorable return. The stated annual return is the simple annual return that a bank gives you on a loan. This interest rate does not take the effect of compound interest into account. The effective annual rate is often used for figuring out the best financial strategies for people or organizations.

Even with honest, completely transparent lenders, it still can be difficult to tell which loan is the least expensive. APRs help you get an apples-to-apples comparison of loans by accounting for every cost related to borrowing. Check your math with an online payment calculator.
