The 5 Year CD Rates are hovering at about 1.69% according to BankRate.com. At the time of this posting I can't think of any good reason to buy a 5yr CD. There is a much better alternative.
There is a 5yr FIA with an "A" Rated company that will keep your money from market risk and pays interest based on the Barklay's Capital Bond Index. In the last 5 years it returned 4.74%, 1.64%, 5.4%, 3.3%, and 4.72%. On top of this interest, owners have 10% liquidity each year. You can't do that with a CD. On top of this liquidity benefit, the account is tax deffered. This means you won't be getting a 1099 each year and owing taxes on the annual growth, further depleating your annual return, until distribution.
