What is ROI?
Return on Investment (ROI) compares the net return from an investment with the original cost. It is useful for a quick percentage view of gain or loss.
ROI = (Gain - Cost) / Cost x 100. Cost must be greater than zero for the formula to work.
Worked example
If you invest $10,000 and receive $15,000 back, the net return is $5,000. ROI = ($15,000 - $10,000) / $10,000 x 100 = 50%.
Practical uses and common mistakes
Use ROI to compare campaigns, projects, purchases, or investments at a high level. It does not show timing, risk, cash flow, taxes, or opportunity cost by itself.
- Do not use ROI alone when timing or risk differs between options.
- Do not forget taxes, fees, maintenance, financing, or labor costs.
- Do not enter revenue as gain unless that is the actual returned value you want to compare.
- Verify important decisions with accounting records, official reports, or a qualified professional.

Frequently Asked Questions
Common questions about ROI Calculator and how to read the result.
What is a good ROI?
It depends on risk, timing, industry, cost of capital, and alternatives. A higher ROI is not automatically better if it carries more risk or takes longer.
What is the ROI formula?
ROI = (Gain - Cost) / Cost x 100. The investment cost must be greater than zero.
Does ROI include time?
No. Basic ROI does not show whether the return happened in one month or five years.
Can ROI be negative?
Yes. ROI is negative when the returned amount is lower than the original investment cost.
Does this include taxes or fees?
No. Taxes, fees, financing costs, maintenance, and other expenses are only included if you build them into your cost or returned amount.
Is ROI business advice?
No. This is a calculation estimate. Important business or investment decisions should be checked against real records and qualified guidance.
