Event ROI calculator
This event ROI calculator estimates what a trade show, webinar, or sponsorship returns: modeled revenue from your own funnel assumptions, minus the cost of running the event, as a percentage of that cost.
Event ROI is the same comparison made afterwards with closed revenue. The calculator is a planning tool, not a reported product metric: replace every starting value, account for costs the preset does not include, and apply your own attribution rule.
The formula
The tool estimates revenue from funnel assumptions. It does not prove that the event caused the modeled deals or deserves all of their revenue:
Each format uses different funnel inputs.
| Event type | Qualified leads |
|---|---|
| Trade show | Badge scans × qualification rate |
| Webinar | Registrations × attendance rate × qualification rate |
| Sponsorship | Leads passed by the organizer × qualification rate |
Each of those counts is produced differently. The trade show ROI guide covers badge scans, qualified leads, and the lag before a booth deal closes. The event sponsorship ROI guide covers what the organizer passes and how to keep leads, booth visits, and impressions apart from closed revenue.
What goes into selected event cost
Every tab adds its listed direct costs and the cost of your team's time. The result is only as complete as those inputs. Add venue, equipment, fees, and any other omitted cost in your finance model before using the figure in a budget decision.
| Event type | Direct cost lines |
|---|---|
| Trade show | Booth space, booth build and logistics, travel and accommodation |
| Webinar | Platform and hosting, promotion budget, content production |
| Sponsorship | Sponsorship package, activation and collateral |
A loaded day rate includes employment costs and overhead. Use the rate approved by your finance team.
Using the webinar ROI calculator
Pick the webinar tab and the inputs change. The model starts from registrations rather than badge scans, applies an attendance rate before qualification, and prices platform and hosting, promotion, and content production instead of booth space and travel. Your close rate, average contract value, and loaded day rate carry across every tab.
The webinar ROI calculator prices a single session. An online conference with a full program carries platform, production, and digital delivery lines this preset does not list; the virtual event ROI guide works through that wider cost base.
Every assumption, written down
The calculator ships with arbitrary illustrative values so you can see how the arithmetic responds. They are not benchmarks, historical averages, or a claim about what an event will return:
| Input | Default | Why this default |
|---|---|---|
| Average contract value | $16,000 | Illustrative placeholder; replace it with your approved value |
| Close rate on qualified leads | 12% | Illustrative placeholder; replace it with your cohort rate |
| Loaded cost of a team day | $600 | Illustrative placeholder; replace it with your finance-approved rate |
| Webinar attendance rate | 42% | Illustrative placeholder; replace it with your own attendance data |
Change any of them and the result changes with it. A calculator that hides its coefficients produces a number nobody can defend in a budget meeting.
Check acquisition cost and close rate
Cost per qualified lead lets you compare the modeled event with another channel under the same qualification rule. A positive modeled return can still sit beside a high acquisition cost.
Close rate on event-sourced leads should come from a defined cohort. Compare it with your broader close rate only when qualification, attribution, and measurement windows use the same definitions.
What this calculator cannot know
The model gives the event full credit for every deal implied by the funnel inputs. That is an explicit scenario, not an attribution finding. Use actual closed revenue and your approved credit rule for a retrospective report.
Multi-touch attribution distributes credit across eligible recorded touches under a documented rule. EventIQ does not do that. It holds one relationship between an event and a Salesforce campaign, confirmed by a person. Ask any vendor, including us, which credit rule it applies and where coverage is incomplete, and expect the answer in the product, not in a slide.
Record the model date and its inputs in the event marketing plan, revisit the same cohort after deals close, and keep open pipeline separate from closed revenue.
