Treasury Bill (T-Bill) Calculator
What Is a T-Bill Calculator?
A T-Bill Calculator is a financial tool that allows you to calculate the discount, purchase price, and yield of U.S. Treasury Bills. T-Bills are short-term government securities with maturities ranging from a few days to one year. They are sold at a discounted price and redeemed at face value upon maturity.
Benefits of Using a T-Bill Calculator:
- Quickly determine investment value
- Calculate yield accurately
- Save time on manual calculations
- Aid in financial planning and portfolio management
Key Formulas Used in the T-Bill Calculator
1. T-Bill Discount
Plain Text Formula:
Discount = Face Value − Purchase Price
Example:
- Face Value = $10,000
- Purchase Price = $9,800
- Discount = $10,000 − $9,800 = $200
2. T-Bill Yield
Plain Text Formula (Bank Discount Rate):
Yield (%) = (Discount ÷ Face Value) × (360 ÷ Days to Maturity) × 100
Example:
- Discount = $200, Face Value = $10,000, Days = 180
- Yield = (200 ÷ 10,000) × (360 ÷ 180) × 100 = 4%
3. Purchase Price
Plain Text Formula:
Purchase Price = Face Value − Discount
Example:
- Face Value = $10,000, Discount = $200
- Purchase Price = $10,000 − $200 = $9,800
4. Maturity Value (Face Value)
Plain Text Formula:
Maturity Value = Purchase Price + Interest
Example:
- Purchase Price = $9,800, Interest = $200
- Maturity Value = $9,800 + $200 = $10,000

Examples of Using the T-Bill Calculator
Example 1: 6-Month T-Bill
- Face Value = $10,000
- Purchase Price = $9,850
- Days to Maturity = 180
- Discount = 10,000 − 9,850 = 150
- Yield = (150 ÷ 10,000) × (360 ÷ 180) × 100 = 3%
Example 2: 3-Month T-Bill
- Face Value = $5,000
- Discount Rate = 2%
- Days to Maturity = 90
- Purchase Price = 5,000 − (5,000 × 0.02 × 90 ÷ 360) = $4,975
- Yield ≈ 2%
Example 3: 1-Year T-Bill
- Face Value = $10,000
- Discount = $400
- Days to Maturity = 360
- Yield = (400 ÷ 10,000) × (360 ÷ 360) × 100 = 4%
