How many of us would like to accumulate a cool million dollars by the time we retire?

Probably all of us, if we were honest with ourselves. Money doesn’t buy happiness but it does pay the bills. Go to the Young Money Web site and play with the Millionaire calculator.

Alter the values in the table to fit your specific situation and hit the calculate button. The graph will indicate your total accumulation, given your assumptions, by your target retirement age. At the top of the table the heading will indicate the age your current plan will actually make you a millionaire! Play with several of the values like savings per month and expected rate of return and notice how the age changes.
