# Defining Periodic Interest Rate

Updated on June 11, 2024 , 1059 views

Periodic interest rate is referred to the rate that is charged over a specific period of time. The periodic rate is equal to the annual interest rate, which is then divided by the number of periods.

For instance, the interest on a loan is generally calculated monthly. Thus, if the annual interest is 4%, you divide this by 12 and get 0.33%. This will be your monthly interest.

## Understanding Periodic Interest Rate

When a Bank puts periodic interest based on the loan’s average balance on a daily or monthly Basis, the effective interest rate is typically higher than the said annual interest rate. The reason behind this is the compounding interest effect.

With overdrafts and credit cards, the interest is calculated daily. This means the daily interest rate is the annual rate, which is divided by 365 days. Since interest gets calculated daily, a massive daily balance on the account will mean you will pay more interest.

The periodic rate’s effect is aggravated when interest rates are generally high. For instance, on a credit card, if the variable interest rate is 16%, the daily interest rate will be 0.044%.

You can also use the effect of this periodic rate to your advantage when you invest your money, given that as long as you are reinvesting the profits or interests. This way, you can easily compound the interest. Over many years, the total value of this investment will be higher than the profit or interest you would have received every month.

## Example of Periodic Rate

Sometimes, businesses find it difficult to manage cash flow as they pay for Raw Materials but don’t get to recover that expense until their products are sold. To make sure they meet financial commitments, a lot of businesses use either an overdraft Facility or take a loan.

On this loan, interest is charged daily. Thus, if they have a huge amount to pay for a massive order and repay the same after a few days, they might end up paying more interest than expected, even if the average loan balance is lower.
