# YIELDDISC function

This article describes the formula syntax and usage of the YIELDDISC function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

## Description

Returns the annual yield for a discounted security.

## Syntax

`YIELDDISC(settlement, maturity, pr, redemption, [basis])`

Important   Dates should be entered by using the DATE function, or as results of other formulas or functions. For example, use DATE(2008,5,23) for the 23rd day of May, 2008. Problems can occur if dates are entered as text.

The YIELDDISC function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

• Settlement    Required. The security's settlement date. The security settlement date is the date after the issue date when the security is traded to the buyer.
• Maturity    Required. The security's maturity date. The maturity date is the date when the security expires.
• Pr    Required. The security's price per \$100 face value.
• Redemption    Required. The security's redemption value per \$100 face value.
• Basis    Optional. The type of day count basis to use.
Basis Day count basis
0 or omitted US (NASD) 30/360
1 Actual/actual
2 Actual/360
3 Actual/365
4 European 30/360

## Remarks

• Microsoft Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900.
• The settlement date is the date a buyer purchases a coupon, such as a bond. The maturity date is the date when a coupon expires. For example, suppose a 30-year bond is issued on January 1, 2008, and is purchased by a buyer six months later. The issue date would be January 1, 2008, the settlement date would be July 1, 2008, and the maturity date would be January 1, 2038, which is 30 years after the January 1, 2008, issue date.
• Settlement, maturity, and basis are truncated to integers.
• If settlement or maturity is not a valid date, YIELDDISC returns the #VALUE! error value.
• If pr ≤ 0 or if redemption ≤ 0, YIELDDISC returns the #NUM! error value.
• If basis < 0 or if basis > 4, YIELDDISC returns the #NUM! error value.
• If settlement ≥ maturity, YIELDDISC returns the #NUM! error value.
