How it works
The ROI calculator compares profit to cost so you can estimate return on investment. It is useful for campaigns, equipment, projects, and small business decisions.
ROI = ((return - cost) / cost) x 100.
Practical examples
- A 1,000 cost that returns 1,300 has 30% ROI.
- Compare two marketing tests with different costs.
- Check if a tool subscription pays for itself.
Common mistakes
- Include all meaningful costs, not only the purchase price.
- ROI does not show timing, risk, or cash flow by itself.
Questions
Is higher ROI always better?
Not always. Risk, scale, and timing also matter.
Can ROI be negative?
Yes. If the return is lower than the cost, ROI is negative.
