Original Investment ($)

This is the original investment amount before any gain or loss.

Investment Start Date (mm/dd/yyyy)

This is the actual, or approximate, day you made the investment. The date can be in the past or in the future if you’re evaluating an investment opportunity.

Returned Value ($)

This is the total returned value of the investment. This can be the projected future value of an investment, or it can be the value actually returned to you from a past investment.

Investment Term (Years)

This is the term of the investment, stated in years. This value is the difference between the start and end dates.

Return on Investment (%)

This is the calculated return on the investment, stated as a percentage. This is the return you received over the entire term of the investment.

Simple Annualized ROI (%)
