About DISC 🔗

The DISC function in Excel is designed to help you determine the discount rate of a security. It is particularly useful in financial evaluations, calculating the rate at which an investment is discounted relative to its face value or initial cost.

To use the DISC function, you need to input details such as the settlement date, maturity date, purchase price, redemption value at maturity, annual coupon rate, and annual yield. You can also specify the frequency of coupon payments per year, which helps refine the calculation based on the interest payment schedule.

The DISC function provides clarity on the discount rate associated with investments, aiding in strategic decision-making regarding securities. By using DISC, you can gain a better understanding of the discount dynamics and valuation metrics of securities, supporting your investment planning and analysis.

Overall, the DISC function is a key tool in Excel for calculating the discount rate of securities, enabling you to assess investment performance and valuation metrics for informed financial decisions.

Examples 🔗

Suppose you have purchased a bond with a redemption value of $1,000, a purchase price of $950, an annual coupon rate of 6%, and an annual yield of 8%. The bond settles on January 1, 2022, and matures on December 31, 2025, with semi-annual coupon payments. The DISC formula would be:

=DISC("1/1/2022", "12/31/2025", 950, 1000, 0.06, 0.08, 2)

This will return the calculated discount rate for the specified bond.

Consider a scenario where you acquire a security with a redemption value of $500, a purchase price of $450, an annual coupon rate of 4%, and an annual yield of 5%. The security settles on March 15, 2022, and matures on October 31, 2024, with annual coupon payments. The DISC formula would be:

=DISC("3/15/2022", "10/31/2024", 450, 500, 0.04, 0.05)

This will yield the determined discount rate for the given security.

Notes 🔗

Use the DISC function with valid Excel date values or references to cells containing valid date values for the settlement and maturity dates. Ensure all inputs, such as settlement date, maturity date, prices, coupon rates, and yield, are accurate for precise results.
