Returns
Remarks
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.
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.
Settlement and maturity are truncated to integers.
If settlement or maturity is not a valid date, TBillYield returns the #VALUE! error value.
If pr ≤ 0, TBillYield returns the #NUM! error value.
If settlement ≥ maturity, or if maturity is more than one year after settlement, TBillYield returns the #NUM! error value.
TBillYield 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.
