Frequently Asked Questions
How do you calculate ROI?+
ROI % = (net gain ÷ cost) × 100, where net gain is typically return − cost. Confirm whether your “return” figure is gross revenue or profit.
Is ROI the same as margin?+
No. Margin compares profit to revenue for a sale. ROI compares gain to the investment outlay for a project or campaign.
Can I share an ROI scenario?+
Yes. ToolVera supports shareable links so stakeholders open the same inputs without retyping.
