Calculates the yield of a US Treasury Bill based on price. Learn more
TBILLYIELD is a financial function in Google Sheets that calculates the yield of a US Treasury Bill based on its settlement date, maturity date, and price. The yield is expressed as an annual percentage rate (APR).
The function syntax is:
TBILLYIELD(settlement, maturity, price)
settlement: The settlement date of the US Treasury Bill, which is the date on which the buyer takes ownership of the security.
maturity: The maturity date of the US Treasury Bill, which is the date on which the security reaches its maturity and the investor receives the face value of the bill.
price: The purchase price of the US Treasury Bill, per $100 face value.
The TBILLYIELD function assumes that the US Treasury Bill has a par value of $100. It also assumes that the actual number of days between the settlement date and maturity date is used to calculate the yield, based on a 360-day year.
