T Bills Calculator

Treasury bills (T-bills) are short-term government securities that offer a low-risk investment option. If you’re investing in T-bills or evaluating their returns, a T Bills Calculator is an essential tool. This calculator helps you estimate the purchase price, yield, discount rate, or investment return of a Treasury bill based on basic financial variables like face value, purchase price, and maturity period.

📊 Key Formulas Used in T Bills Calculations

The T Bills Calculator is based on the following formulas:

1. Discount Rate (DR)
   DR = ((Face Value - Purchase Price) / Face Value) * (360 / Days to Maturity)
2. Investment Yield (IY)
   IY = ((Face Value - Purchase Price) / Purchase Price) * (365 / Days to Maturity)
3. Purchase Price (PP)
   PP = Face Value / (1 + (IY * Days to Maturity / 365))
4. Holding Period Return (HPR)
   HPR = (Face Value - Purchase Price) / Purchase Price

These formulas adhere to standard financial practices used in Treasury bill evaluations.

💡 Example Calculation

Let’s walk through an example:

• Face Value: $1,000
• Purchase Price: $980
• Maturity Period: 90 days

Step 1: Calculate Discount Rate

DR = (($1,000 - $980) / $1,000) * (360 / 90)
DR = (20 / 1000) * 4 = 0.02 * 4 = 0.08 or 8%

Step 2: Calculate Investment Yield

IY = (($1,000 - $980) / $980) * (365 / 90)
IY ≈ (20 / 980) * 4.06 ≈ 0.02041 * 4.06 ≈ 0.0828 or 8.28%

So, a $980 investment in a 90-day T-bill yields approximately 8.28% annually.
