The Rule of 72
A simple concept called "The Rule of 72" shows the effect of time and compounding on your money. The Rule of 72 is an equation that states that your money will double approximately at the point in time determined by dividing 72 by the percent of interest you earn.  Therefore, if you're earning 7%, then it will take about 10.28 years for your money to double.
(72 divided by 7)

At a 28% tax bracket, you could save $560 in taxes in one year, just by starting an IRA.

When does $14,000 equal $68,000?

Here we have an example of two investors in IRA's. Individual A knows the importance of deductibility and time. Remember that the money accumulating is tax deferred so every cent goes to building a secure retirement. Individual B has the right idea but time hurt him severely. It's simple, while people waste time looking for "get rich quick" schemes, the best investments are available to them. Qualified retirement plans, like IRA's and Keogh's combine the power of time and money, with the added benefit of tax deductibility and tax deferability. A good retirement rule of thumb: Before you begin any other kind of investment, maximize your IRA. Note that Individual A began early at age 22 and funded for 7 years, yet they both had about the same amount of savings at age 61.
