How is ROI calculated?

ROI is the profit divided by the initial investment, multiplied by 100. Profit is the final value minus the initial investment.

What does a negative ROI mean?

It means the final value is lower than the amount invested, so the investment made a loss.

Does ROI account for time?

No. Basic ROI does not consider how long the investment was held. For time-based comparisons, look at annualised return instead.
