A Treasury Bill (T-Bill) is a short-term government debt instrument with a maturity of less than one year. Treasury Bills are used by governments to manage their short-term cash flow needs and are considered one of the safest investments available.
Types of Treasury Bills
Treasury Bills are classified based on their maturity periods:
- 4-week T-Bills: Maturities of 28 days.
- 13-week T-Bills: Maturities of 91 days (approximately 3 months).
- 26-week T-Bills: Maturities of 182 days (approximately 6 months).
- 52-week T-Bills: Maturities of 364 days (approximately 1 year).
How Treasury Bills Work
Treasury Bills are sold at a discount from their face value. Investors purchase T-Bills for less than their face value and receive the full face value at maturity. The difference between the purchase price and the face value is the interest earned by the investor.
The yield on a T-Bill can be calculated using the following formula:
$$
\text{Yield} = \left( \frac{\text{Face Value} - \text{Purchase Price}}{\text{Purchase Price}} \right) \times \left( \frac{365}{\text{Days to Maturity}} \right)
$$
For example, if a 26-week T-Bill has a face value of $10,000 and is purchased for $9,800, the yield would be:
$$
\text{Yield} = \left( \frac{10,000 - 9,800}{9,800} \right) \times \left( \frac{365}{182} \right) \approx 4.06\%
$$
