How It Works

ROI is calculated by subtracting the cost of investment from the final value, dividing by the cost, and multiplying by 100.

Worked Examples

Stock Investment ($1,000 → $1,200)

Initial Investment:$1,000= Cost

Final Value:$1,200= Return

Net Profit:1,200 - 1,000= $200

ROI Formula:(200 / 1,000) × 100= 20%

Tips & Best Practices

•A positive ROI means the investment made money; negative means a loss.
•Annualized ROI helps compare investments held for different time periods.
•Consider taxes and fees which reduce your net ROI.
