How this calculation works
Calculate investment return, discount rate, and annualized investment yield on short-term government Treasury Bills.
Mathematical formula and logic
Annualized Yield % = [(Face Value - Purchase Price) / Purchase Price] × (365 / Days) × 100.
Worked example
A 91-day T-Bill bought at $98.20 with $100 face value yields 7.36% annualized.
Calculation assumptions
- Year is calculated on a 365-day basis.
- T-Bills are zero-coupon instruments issued at a discount.
