The Effective Annual Rate (EAR) is calculated using the following formula:
EAR = (1 + (Nominal Rate / Compounding Frequency)) ^ Compounding Frequency - 1
Where:
- Nominal Rate: The nominal interest rate in percentage.
- Compounding Frequency: The number of times interest is compounded per year.
The formula calculates the annual interest rate that takes into account the effect of compounding over the year.
What is Effective Annual Rate?
The Effective Annual Rate (EAR), also known as the Annual Equivalent Rate (AER), is a financial metric used to represent the annualized interest rate or yield on a financial product or investment, accounting for compounding. It provides a more accurate measure of the true annual cost or return on an investment or loan, taking into consideration how interest is compounded within a year.
All Formulae Related to Effective Annual Rate
Here are the formulas related to the Effective Annual Rate (EAR) in plain text format for easy copying and pasting:
Effective Annual Rate (EAR) Formula:
- The formula calculates the Effective Annual Rate (EAR) when you have the nominal annual interest rate (r) and the number of times interest is compounded per year (n).
Effective Annual Rate (EAR) = (1 + (r / n))^n – 1
Where:
- EAR is the Effective Annual Rate (expressed as a decimal).
- r is the nominal annual interest rate (expressed as a decimal).
- n is the number of times interest is compounded per year.
