What is broken period interest?

Broken period interest means the interest calculation method is used when a financial transaction, such as a loan or bond, spans partial interest periods. This typically occurs when the period between two interest payment dates is not a whole number of interest periods. Let’s understand it with an example.

What is Broken Period Meaning?

For example, let's say you take out a loan on March 15th, and the interest is payable semi-annually on June 30th and December 31st each year. If you repay the loan on September 15th, you've only held the loan for part of the interest period between June 30th and December 31st.

In this case, the interest calculation for the partial period from June 30th to September 15th would involve broken period interest.

• The broken period interest calculation adjusts for the fraction of the interest period that the transaction covers. It ensures that the interest charged or earned accurately reflects the time value of money for the partial period.

• The calculation method may vary depending on the terms of the financial instrument and the conventions followed by the lender or issuer.

: This method calculates the actual number of days in the partial interest period and divides it by the actual number of days in the full interest period.

: This method assumes that each month has 30 days and each year has 360 days. It calculates the fraction of the partial interest period relative to a full 360-day year.

: Similar to Actual/Actual, this method calculates the actual number of days in the partial interest period and divides it by 365 days.

: This method assumes a fixed 365-day year and calculates the actual number of days in the partial interest period.

The choice of method depends on the terms of the financial instrument, market conventions, and regulatory requirements. This is what broken period interest means.

Broken period interest meaning is the interest charged for a period that is shorter than a full interest period, such as a month.

This concept is given in financial calculations, mostly in the context of loans, mortgages, and bonds. When a financial transaction is for a limited period, the interest for that period is calculated based on a proportional rate. It takes into account the fraction of the full period that is being covered.

Let's  take an example of broken period interest loan repayment:

Assume you have a loan with an annual interest rate of 6%. If your interest is calculated on an annual basis, the annual interest rate would be divided by 12 months to calculate the monthly interest rate:

Monthly Interest Rate = Annual Interest Rate / 12 = 6% / 12 = 0.5%

Now, if you make a loan payment in between the month, you will have a "broken period" of less than one full month. Let's say you made the payment on the 15th of the month. The number of days in the "broken period" would be 15.

Broken Period Interest = (Loan Amount) x (Monthly Interest Rate) x (Number of Days in Broken Period / Number of Days in Full Month)

Using this formula, you can calculate the interest for the 15-day "broken period" on the loan amount.

Broken Period Interest = (Loan Amount) x (0.5%) x (15 days / 30 days) = (Loan Amount) x 0.25%

This is a simple example of what is broken period interest

concept is.

Financial institutions and calculators also use more factors like leap years and varying month lengths.
