USD simple fixed-coupon estimate; no reinvestment. Months use 1/12 year and days use 1/365 year. Actual coupon dates, contract day-count and tax rules can differ.

Debenture Interest Formula

The following equation is used to calculate the Debenture Interest.

DI = P × r × t
  • Where DI is the debenture interest ($)
  • P is the face value used for the coupon calculation ($)
  • r is the annual coupon rate as a decimal
  • t is time in years; the calculator converts months using 12 months/year and days using 365 days/year

To estimate simple coupon interest, multiply face value by the annual coupon rate as a decimal and time in years. Coupon frequency divides annual interest into equal full payments; a fractional period is an accrual estimate, not a count of cash payments. The estimate excludes reinvestment and does not calculate market yield.

What is Debenture Interest?

Definition:

Debenture interest refers to the interest paid on a debenture, which is an unsecured debt instrument that companies often issue to raise capital. The interest rate and schedule are typically defined in the debenture agreement.

How to Calculate Debenture Interest?

Example Problem:

The following example outlines the steps and information needed to calculate the Debenture Interest.

First, determine the principal amount. In this example, the debenture principal is $10,000.

Next, determine the annual interest rate. In this case, it’s 5% (0.05 as a decimal), and the time period is 2 years.

Finally, calculate the debenture interest using the formula above:

DI = P × r × t

DI = $10,000 × 0.05 × 2

DI = $1,000
