The Core Mechanics of Compounding Compounding is the process of earning interest on previously accrued interest. The effective annual rate strips away this ambiguity by converting the nominal figure into a true annual percentage that reflects the mathematical reality of compounding.
How to Calculate Effective Annual Rate for Savings
The Calculation Formula The standard formula for calculating the effective annual rate is EAR = (1 + i/n)^n - 1. A higher compounding frequency accelerates growth or debt because interest is calculated and added to the principal balance more often.
Users can input the nominal rate and compounding frequency to instantly generate the EAR. Understanding this distinction is essential for making informed decisions about savings, loans, and any capital deployment.
