T-Bills are discounted bonds. In simple terms this mean the T-Bills sell below value and mature at their value. When reviewing T-Bills, the higher the interest rate is, the less the T-Bill will be and vice-versa.

T-Bills can be set up by making single investments or repeat purchasing by directly funding from your checking account. T-Bills can seem complex, an easy way to understand T-Bills is with an example. Let's say you want to buy a T-bill with a $1,000.00 investment. You will actually be charged $980.00 or so, you then receive the $1000.00 when the T-Bill reaches maturity. The $980 figure is calculated based on the discount rate, basically subtracting the interest required to make the $1,000.00. T-Bills function as though you are aiming at a final amount.

T-Bills may seem like a low return investment but, when you consider the return across a year, that can translate into a good return on investment, particularly if you re-invest your money back into T-Bills. This provides a compound interest savings approach

The downside of T-Bills is that the discount rate isn't published ahead of the investment and the rates don't always keep track with inflation. T-Bills do however allow the reinvestment of American money back into the American economy meaning less foreign borrowing and a stronger Dollar. That is probably not your biggest concern when investing your money but a strong dollar does drive better interest rates and mean cheaper imports (good if you like your technology from the Far East).
