Syntax

PRICEDISC(settlement,maturity,discount,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.

Settlement is 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 is the security's maturity date. The maturity date is the date when the security expires.

Discount is the security's discount rate.

Redemption is the security's redemption value per $100 face value.

Basis is 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. Microsoft Excel for the Macintosh uses a different date system as its default.
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, PRICEDISC returns the #VALUE! error value.
If discount ≤ 0 or if redemption ≤ 0, PRICEDISC returns the #NUM! error value.
If basis < 0 or if basis > 4, PRICEDISC returns the #NUM! error value.
If settlement ≥ maturity, PRICEDISC returns the #NUM! error value.
PRICEDISC is calculated as follows:

where:

B = number of days in year, depending on year basis.

DSM = number of days from settlement to maturity.
