This article describes the formula syntax and usage of the TBILLPRICE 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.
Returns the price per $100 face value for a Treasury bill.
TBILLPRICE(settlement, maturity, discount)
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 TBILLPRICE 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 Treasury bill's settlement date. The security settlement date is the date after the issue date when the Treasury bill is traded to the buyer.
- Maturity Required. The Treasury bill's maturity date. The maturity date is the date when the Treasury bill expires.
- Discount Required. The Treasury bill's discount rate.
- 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.
- Settlement and maturity are truncated to integers.
- If settlement or maturity is not a valid date, TBILLPRICE returns the #VALUE! error value.
- If discount ≤ 0, TBILLPRICE returns the #NUM! error value.
- If settlement > maturity, or if maturity is more than one year after settlement, TBILLPRICE returns the #NUM! error value.
- TBILLPRICE is calculated as follows:
- DSM = number of days from settlement to maturity, excluding any maturity date that is more than one calendar year after the settlement date.
The example may be easier to understand if you copy it to a blank worksheet.
