  • Any of the arguments is not a numeric value.

Example

To get the price per $100 face value for a Treasury bill with the information as shown below, please copy or enter the formula below in a blank cell, and press Enter to get the result:

=TBILLPRICE(DATE(2021,3,21),DATE(2021,9,30),3.5%)

Or, use cell references to make the formula dynamic:

=TBILLPRICE(C3,C4,C5)

If a Treasury bill has the same information above except that the settlement date is May 1, 2021, you can replace the C3 in the formula with the DATE function:

=TBILLPRICE(DATE(2021,5,1),C4,C5)
