If you follow the Roth IRA Rules, any contributions you make towards a Roth IRA will grow taxfree for years to come, and with the power of compound interest, your money will grow at even a faster pace! Upon retirement, you will NOT have to pay taxes on your Roth IRA earnings as well. Furthermore, Roth IRAs allow you to invest in many different investments such as Bonds, Stocks, Real Estate, Derivatives, Mutual Funds and more.
A Roth IRA account can be opened until April 17th of the current tax year, and contributions can made starting from the previous year. The current maximum Roth IRA limit for 2006 is $4000. From 2010, the maximum Roth IRA contribution limit will rise to $5000.
Compound Interest & Roth IRA?
If a young saver at the age of 25 invests $4000 a year into a Roth IRA and earns 8% a year on his investment, he will have a huge nest egg of $1.1 million upon retirement (at the age of 65). What’s more, none of this $1.1 million nest egg is taxable upon retirement!
Consider a contraexample scenario. If that same 25 year old young saver invests $4000 a year into a regular taxable savings account earning 8% interest, he would grow a nest egg of $800,000 upon retirement (at the age of 65) – assuming a 15% tax rate.
Characteristics of a Roth IRA Account

Distributions or Withdrawals on your contributions from a Roth IRA account can be taken out at any time without incurring the 10% early withdrawal penalty fee in 401k accounts, as well as no taxes payable.
Note: A Roth IRA is meant for saving towards retirement and withdrawals from your retirement savings account are always discouraged (unless for emergencies and unexpected circumstances).
Note: Also note that withdrawals from your Contributions are non taxable. However, any earnings you have made on those contributions (such as the 8% interest earnings) is taxable at your local state & federal taxes and subject to 10% early withdrawal penalty fee (if withdrawn before the age of 59 and 1/2).
