What does this tool do?
Event ROI Calculator computes the result directly in your browser — Every event should pay for itself and then some. This computes your event ROI from total revenue and costs, so you know whether it's a money-maker or a loss leader. Nothing you enter is uploaded or stored.
Formula: event ROI = (total revenue − total cost) ÷ total cost, often shown as a multiple (revenue ÷ cost). Include ALL costs: venue, catering, staffing, marketing, AV, insurance, permits — not just the headline line. Count ALL revenue: tickets, sponsorships, on-site sales, and future pipeline the event generates. Soft value: brand awareness and lead generation are real ROI even when direct revenue doesn't cover costs — decide deliberately whether an event is a profit center or an acquisition cost.
How this calculator works
ROI = (attributed gross profit - total event cost) / total event cost x 100. Cost includes booth, travel, staff time, and swag, not just sponsorship.
Worked example
$30,000 total cost producing $75,000 of attributed gross profit is (75,000-30,000)/30,000 = 150% ROI.
FAQ
How do you calculate event ROI?
Divide net profit (revenue minus all costs) by total cost, then multiply by 100 for a percentage. A revenue-to-cost multiple is also useful for sponsors.
What should my event ROI target be?
For a revenue-focused event, aim for at least 1.5-2x (50-100% ROI) to justify the risk and effort. For acquisition events, measure cost-per-lead and pipeline generated, not just direct ROI.
What costs do people forget?
Staff time, insurance and permits, AV rentals, clean-up, and credit-card fees are commonly missed. Missing costs inflate ROI — use a full budget line.
