How to Read the SLGS Daily Rate Table
If you're having trouble reading the SLGS Daily Rate Table, this page should help you.
The rate table includes interest rates for securities with a maturity of one month up to 40 years.
For Time Deposit securities, the interest rate earned is one basis point below the current Treasury borrowing rate for a security of comparable maturity.
For Demand Deposit securities, the interest rate is based on an adjustment of the average yield in the most recent auction of 13-week Treasury bills.
The SLGS Daily Rate Table is created by the Department of the Treasury each federal business day and published by the Bureau of the Public Debt no later than 10:00 a.m. ET.
Below is a partial SLGS Daily Rate Table, dated January 15, 2008.

As you can see, the Demand Deposit rate covers all Demand Deposit securities issued, regardless of the redemption date. For Time Deposit securities, you must know the security's life (i.e., term) to find your maximum allowable rate.
The column headings From and Through refer to your security life. For instance, if you have a security that is issued February 1, 2008, and matures February 1, 2009, then your security's life is exactly 1 year. In this example, the security's term falls between the From of 01-00 (meaning one year, zero months) and the Through of 01-02 (meaning one year, two months). So, for this security, the maximum interest rate available is 2.86%.
You may also choose any interest rate from 0% to 2.86% for your security. You are not required to accept the maximum allowable rate, but you cannot choose an interest rate higher than the maximum allowable rate. See a more detailed interpretation of the SLGS Daily Rate Table's From and Through columns.
If your security's life is more than one time increment, but not quite the next increment, use the shorter term. For example, if your security were held for 45 days, you would use the 00-01 (one-month) rate of 3.17%, not the rate for 00-02 (two months).
