US T-Bills (Treasury Bills) are very safe short term bonds supplied by the US government, with a maturity period of less than one year.
The yield (profit) is low due to the ultra-safe nature of the bond, the US Government promises to pay the face value of the bond over the agreed maturity period, the price you pay for the bond is determined by competitive bidding.
There are no interim payments over the period, the face value of the bond is paid at the end of the period.
T-Bills are usually sold in dominations of $1000, and the standard periods are one month (4 weeks), Three months (13 weeks) or six months (26) weeks.
In the calculator below the face value of the bonds can be selected from a drop down list of common values, or the value can be entered in the Other Value box if not in the list.
Likewise the maturity period can be selected from the drop-down list or entered in the Other Period box.
The annual interest rate is calculated for information only.
For example, you buy a $5000 T-Bill for $4800 over three months. Your profit is $200, the rate of return is 4.17%
