How to Calculate ROI
Return on investment measures how much profit or loss an investment generates compared with its total cost. A positive ROI indicates a profitable investment, while a negative ROI indicates a loss.
Use the same currency for every amount so the result remains accurate and easy to compare.
ROI Formula
ROI = (Net Profit ÷ Total Investment) × 100
Net Profit = Gross Revenue − Initial Investment − Additional Costs
ROI Calculation Example
Here is a simple example using the same currency for every value.
$5,000
Initial investment
$8,500
Gross revenue
$700
Additional costs
49.12%
Calculated ROI
The total cost is $5,700 and the net profit is $2,800. Dividing net profit by total investment produces an ROI of approximately 49.12%.
