It is also called the effective interest rate, the effective rate, or the annual equivalent rate (AER). Going back to the previously mentioned shortages of the nominal interest rate, if we take into account the effect of compounding interest, we obtain the Effective Annual Rate (EAR or EFF%). The concept of EAR is the same as that for the Annual Percentage Yield (APY), however, the latter form is applied mainly on investments or savings account. Since the compounding period may vary in different types of financial instruments, one of the main advantages of the Effective Annual Rate is that the financial products became comparable. The higher the effective annual interest rate is, the better it is for savers/investors, but worse for borrowers.

The effective interest rate of 4%, compounded quarterly, is approximately 4.06% with a periodic rate of 1%. On the other hand, if compounded monthly, the effective interest rate would be approximately 4.074%, with a periodic rate of 0.3333%.
Understanding the Effective Annual Interest Rate

Simply put, the effective annual interest rate is the rate of interest that an investor can earn (or pay) in a year after taking into consideration compounding. APR is aimed at imparting and pointing out these fees and expressing them in the yearly rate. Therefore, APR might be a better measure when you are about to evaluate the real cost of borrowing or want to compare different loan offers.
Compare effect of compounding periods
The purpose of the effective annual interest rate is to make interest rates comparable regardless of their compounding periods. Investors, savers, or borrowers can take nominal rates with different compounding periods (e.g., one that compounds weekly, one that compounds monthly) to see which will be most beneficial to them. An effective annual interest rate is the real return on a savings account or any interest-paying https://www.quick-bookkeeping.net/what-is-depreciation-and-how-do-you-calculate-it/ investment when the effects of compounding over time are taken into account.
