Are your deposits FDIC insured?

For your deposits to be insured they generally need to fall under all three conditions

1. The institution is a member of the FDIC
2. The account is a CD, money market, checking, savings, trust or IRA retirement savings account (Note: money market funds, mutual funds, annuities, life insurance policies, stocks or bonds are NOT insured)
3. Under $100,000 per depositor, per insured bank (This is the basic insurance amount and may be greater depending on account formation. See the EDIE to estimate FDIC insurance coverage)
   

The rule of thumb regarding insurance is provided by the following FDIC statement:

If you and your family have $100,000 or less in all of your deposit accounts at the same insured bank, you do not need to worry about your insurance coverage -- your deposits are fully insured.

Deposits in Credit Unions fall under similar rules, see details at the NCUA.
