 Starting balance
 Total amount that you currently have invested. Include any sources of investment savings such as 401(k)s, IRAs and Annuities that you wish to include in this analysis.
 Amount to contribute
 This is the amount that you will add to your investment savings. You can add additional amounts weekly, monthly, quarterly or annually. All contributions are assumed to be made at the beginning of each period.
 Annual return
 This is the annual rate of return you expect from your investments after taxes. When withdrawing, the return earned is often assumed to be lower due to more conservative investment choices to help insure a steady flow of income. The actual rate of return is largely dependent on the type of investments you select. For example, from December 1999 to December 2009, the average annual compounded rate of return for the S&P 500 was 0.6%, including reinvestment of dividends. From January 1970 to December 2009, the average annual compounded rate of return for the S&P 500, including reinvestment of dividends, was approximately 10.1% (source: www.standardandpoors.com). Since 1970, the highest 12month return was 61% (June 1982 through June 1983). The lowest 12month return was 43% (March 2008 to March 2009). Savings accounts at a bank may pay as little as 1% or less but carry significantly lower risk of loss of principal balances.
It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for longterm investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that funds and/or investment companies may charge.
 Years to contribute
 This is the number of years you will be adding new money to your investment savings. If you wish to start withdrawals immediately, enter 0 for the years to contribute.
 Inflation rate
 What you expect for the average longterm inflation rate. A common measure of inflation in the U.S. is the Consumer Price Index (CPI), which has a longterm average of 3.1% annually, from 1925 through 2009. The CPI for 2009 was 1.0%, as reported by the Minneapolis Federal Reserve.
 Inflation adjustments and your contributions
 To keep your periodic contributions at the same level choose the option "No adjustment for inflation". If you select "Adjust contributions annually for inflation" we will increase your periodic contribution at the end of each year by the rate of inflation.
 Amount to withdraw
 This is the amount that you expect to be withdrawing from your investment savings. You can make withdrawals weekly, monthly, quarterly or annually. All withdrawals are assumed to be taken at the beginning of each period. If you choose the option to "Calculate maximum withdrawal" this field will be calculated.
 Withdrawals to last
 This is the number of years that your withdrawals are to last. If you choose the option to "Calculate time balance will last" this field will be calculated.
 Inflation adjustments and your withdrawals
 These selections allow you to adjust your withdrawals for inflation. If you choose "No adjustment for inflation" your withdrawal will remain at a constant amount for the entire duration of your withdrawals. "Inflation adjustments begin with withdrawals" will increase your withdrawal amount at the end of each year by the rate of inflation. This begins at end of the first year of withdrawals. "Inflation adjustments begin immediately" will increase the withdrawal amount, that was entered or calculated, by the rate of inflation beginning immediately. Choosing this option helps illustrate the cost of providing a current amount of purchasing power throughout your withdrawals.
