General Assumptions
- I calculated all scenarios based on an annual return of 3.51 percent, which was the average return of the US
stock market between the low point of the Great Depression in 1932 and the high point in October 2007.
- All returns include the average inflation rate of 3.69 percent between 1932 and 2007.
- The starting point is zero dollars and the assumed lifetime is 90 years. This means that any retirement savings needs to last for
25 years (from 65 to 90).
- Contributions before retirement are tax deferred, i.e. tax free. All withdrawals during retirement are taxed at 15%.
- During 25 years of retirement, all savings are used up down to zero at age 90.

You have zero savings and start saving at age 30 until age 65.
