The following formula is used in the above calculations:

$F=P\times (1+i\times {\displaystyle \frac{{\displaystyle \frac{\mathrm{Year}}{2}}}{\mathrm{Year}}})\times (1+i\times {\displaystyle \frac{\mathrm{Days}-{\displaystyle \frac{\mathrm{Year}}{2}}}{\mathrm{Year}}})$
$P=\text{Purchase price}$
$F=\text{Face value}$
$i=\text{BEY (Bond Equivalent Yield)}$
$\mathrm{Days}=\text{Days to maturity}$
$\mathrm{Year}=\text{365 or 366}=\text{Actual number of days in the year}$

As you can see from the above formula, the BEY (Bond Equivalent Yield) represents the annualized rate of the compounding interest you earn on your investment (the price you paid for the T-Bill).

Note that if the T-Bill is maturing in less than or equal to one half-year, the compounding interest should be replaced by a simple interest.
