What is the TBILLPRICE Function?

The TBILLPRICE Function[1] is categorized under Excel FINANCIAL functions. The function will calculate the fair market value of a Treasury bill / bond.

In financial analysis, TBILLPRICE can be useful in determining the value of a bond and deciding if an investment should be made or not. It helps calculate the FMV of a Treasury bill when we are given the settlement, maturity, and discount rate information.
