When it comes to planning for retirement, there are a number of financial products. One that has become increasingly popular are annuities, which are a form of guaranteed income that act as purchase insurance.
One aspect that many find appealing about annuities is they aren't subject to conditions such as fluctuations of the economy, or to a certain point anyways. There are fixed and variable annuities to look into. While the interest rate can change, the principal is safe.
While an annuity is going through its growth period, there are not taxes involved. And they're often more liquid that other investments like CDs or treasury bonds.
