Definitions

Years
The number of years you wish to analyze. This can be any number from one to one hundred.

Rate of return
This is the annually compounded rate of return you expect from your investments before taxes. The actual rate of return is largely dependant on the type of investments you select. For example, from January 1970 to February 2003, the average compounded rate of return for the S&P 500, including reinvestment of dividends, was approximately 11%. Savings accounts at a bank pay as little as 1% or less. It is important to remember that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment.

Compound Interest
Interest on an investment's interest, plus previous interest. The more frequently this occurs, the sooner your accumulated interest will generate additional interest. You should check with your financial institution to find out how often interest is being compounded on your particular investment.

Initial investment
Total you currently have invested that should be included in this analysis.

Inflation rate
What you expect for the average long-term inflation rate.

Annual investments
The amount you will contribute each year to your investments. If you check the box to adjust this amount for inflation, your annual investment will increase each year by the inflation rate.

Tax rate
The percentage of your investment return you will pay in taxes. Your taxes are assumed to be payable annually, at the end of the year.

Compounded interest return
Total after-tax return if your investment profit is compounded annually.

Simple interest return
Total after-tax return if your investment profit is simple interest with no compounding.

Total invested capital
Total you have invested. This includes your initial investment and all periodic investments.

Investment final total
Your investments total ending value. If you have checked the box to show values after inflation, this amount is the total value of your investment in today's dollars. If this box is unchecked, it will show the actual value of the investment.
