How to calculate T-Bill yield?

Calculating potential yield on a T-Bill before placing a bid in auction can be helpful in setting a fixed minimum interest rate as part of a competitive bid on treasury bills.

To calculate the yield on a T-Bill, you will need the following information:

  • The face value of the T-Bill
  • The discount rate (the amount of interest paid at maturity)
  • The current market price for the T-Bill

Once you have this information, you can use the T-bill calculator above to calculate the yield.

Example

  • Let’s say you want to buy $1,000 worth of 6-month T-bills, offering an annual yield rate of 5%.

    5% annualized yield on $1,000 over a period of 6 months is $25. Because Treasury bills are purchased at a discount to their face value, you’ll pay about $975. Then, when they reach maturity after 6 months, you’ll get the full $1,000, netting you a $25 profit.

How do Treasury Bills Work?

The U.S. Treasury department provides Treasury securities, including Treasury Bills, with short-term maturity as a means of funding government projects.

Investors can buy Treasury bills from the government at a discounted price and then redeem them when they reach maturity, which can vary from a few weeks to one year.

If a Treasury bill is cashed out before maturity, the owner has the option to resell it on the secondary market. When Treasury bills reach maturity, investors are given the entire face value by the federal government. The investment income earned is based on the discounted amount at the time of purchase.
