Argument

Description

Remarks

settlement

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.

• If settlement > maturity, or if maturity is more than one year after settlement, this function returns the #NUM! error value.

• If a valid date is not entered for this argument, this function returns the #VALUE! error value.

• If this argument contains a decimal value, this function ignores the numbers to the right side of the decimal point.

maturity

The Treasury bill's maturity date. The maturity date is the date when the Treasury bill expires.

• If a valid date is not entered for this argument, this function returns the #VALUE! error value.

• If this argument contains a decimal value, this function ignores the numbers to the right side of the decimal point.

discount

The Treasury bill's discount rate.

• If this argument is ≤ 0, this function returns the #NUM! error value.

## General remarks

• 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.

• TBILLPRICE is calculated as follows:

Where:

DSM = number of days from settlement to maturity, excluding any maturity date that is more than one calendar year after the settlement date.
