🏦 Treasury Bill Calculator

The MultiCalculators Treasury Bill Calculator is designed for investors, finance students, and treasury professionals who need instant, accurate pricing and yield of U.S. Treasury bills (T-bills) and similar discount securities. T-bills are short-term debt obligations issued at a discount to face value; the profit is the difference between the purchase price and the amount received at maturity. This tool uses the standard bank discount method (360-day year) to compute the discount amount and purchase price. It then calculates the bond equivalent yield (BEY) for easy comparison with coupon bonds using a 365-day year. Our calculator supports standard tenors: 4-week (28d), 13-week (91d), 26-week (182d), and 52-week (364d). You can also manually adjust discount rate and face value. Results update instantly with a single click – fully transparent and free.

Why choose our T-Bill calculator? Unlike generic tools, we emphasize both discount yield and investment yield (BEY), giving you a complete picture. For example, a $1,000 T-bill with 91 days to maturity and a discount rate of 4.85% purchases at ~$986.27; your discount is $13.73. The bank discount yield is exactly 4.85%, while the bond equivalent yield is around 5.01% – reflecting the true annualized return. Our calculator also works for any custom days and discount rate, making it suitable for non-standard maturities. Responsive design ensures seamless use on mobile, tablet, or desktop. We follow industry convention: discount rate = (discount/face) × (360/days). Bond equivalent yield = (discount/price) × (365/days). All outputs are rounded to two decimal places for clarity.
