What is a T-Bill Yield?

The T-Bill yield represents the annualized return an investor earns from buying a Treasury Bill at a discount and receiving its face value at maturity (usually within 4, 13, 26, or 52 weeks). Since T-Bills do not pay periodic interest, the yield reflects the implied interest earned.
