## What is Periodic Interest Rate?

The periodic interest rate is the interest rate that is applied over a specific compounding period within a year. It is also known as the “nominal interest rate,” “annual nominal rate,” or “stated interest rate.” This rate represents the interest that is charged or earned on a financial instrument, such as a loan or an investment, over a single compounding period, which could be a month, a quarter, or any other defined time frame.

## All Formulae Related to Periodic Interest Rate

The periodic interest rate is used in financial calculations involving compound interest. Here are some formulas related to the periodic interest rate:

**Calculating the Periodic Interest Rate (r/n)**: The periodic interest rate, denoted as (r/n), can be calculated from the annual interest rate (r) and the number of compounding periods per year (n) using the formula:(r/n) = Annual Interest Rate / Number of Compounding Periods per Year**Effective Annual Rate (EAR)**: The Effective Annual Rate is used to compare the true cost or return of different financial products. It takes into account the effect of compounding over multiple periods per year. To calculate the EAR, use the following formula:EAR = (1 + (r/n))^n – 1Where:- r is the annual interest rate.
- n is the number of compounding periods per year.

**Converting Periodic Interest Rates**: To convert a periodic interest rate to an equivalent annual interest rate, you can use the following formula:Annual Interest Rate = (Periodic Interest Rate) * (Number of Compounding Periods per Year)**Converting Annual Interest Rate to Periodic Interest Rate**: To convert an annual interest rate to a periodic interest rate, you can use the following formula:Periodic Interest Rate (r/n) = Annual Interest Rate / Number of Compounding Periods per Year
