#### Assumptions

- Sourced pipeline = (leads × lead conversion × deal size) + (meetings × meeting conversion × deal size).
- ROI multiple = sourced pipeline ÷ all-in event cost.
- Cost per opportunity = event cost ÷ expected opportunities from both streams.
- Benchmark scenario applies lifts for earlier outreach, tighter ICP, same-day follow-up, and assumes at least 10 pre-booked meetings.

Numbers are a planning estimate based on the inputs above. Open the URL to reproduce the exact scenario, change any field, and recalculate live.

Next step

#### Want to hit the top bar at your next event?

Luminik pre-books meetings with ICP-matched attendees 4–8 weeks before the doors open, then attributes sourced pipeline back to the event in your CRM.

## B2B event ROI

Model sourced pipeline against all-in event cost, so the event review starts with revenue math instead of booth traffic.

## Cost per opportunity

Calculate the leading efficiency metric finance can inspect before closed-won revenue arrives.

## Pipeline left on the table

Compare badge-led follow-up against a pre-event motion with ICP scoring, meetings, and same-day CRM sync.

## How the calculator works

How is ROI actually calculated here? 

Two pipeline streams are summed: (1) leads captured × lead → closed-won % × average deal size, and (2) pre-booked meetings × meeting → closed-won % × average deal size. Sourced pipeline divided by all-in event cost gives you the ROI multiple. Cost per opportunity uses the same pipeline numerator, not closed-won revenue. It's the leading indicator CFOs tend to believe.

What's the benchmark scenario comparing against? 

The with-pre-event-motion bar applies three documented lifts on top of your own numbers: starting outreach 3+ weeks early, tighter ICP match, and same-day follow-up. It also assumes at least 10 pre-booked meetings, which is the threshold where events tend to flip profitable.

What counts as 'pipeline left on the table'? 

The gap between the pipeline your inputs produce today and the pipeline the same spend produces with a pre-event motion in place. It's the delta between the top-quartile and bottom-quartile teams working the same event, same budget, different motion.

Is the link shareable? 

Yes. Every input is encoded into the URL as you type, so the address bar is always a live deeplink to the exact scenario you modelled. Copy shareable link copies it to your clipboard for Slack or email. No signup, no tracking pixel.

Can I download a PDF for my CFO? 

Yes. Print / save PDF opens your browser's print dialog. Pick Save as PDF as the destination and you get a clean one-pager with the inputs, outputs, assumptions, the Luminik logo, and the shareable URL. Everything runs locally in your browser.

Do I need to sign up? 

No. Everything runs in your browser. Copy summary for CFO writes a clean plain-text block to your clipboard for email or Slack.

Can I use this as a conference ROI calculator? 

Yes. The model works for trade shows, industry conferences, roadshows, executive dinners, and sponsored events. For conference ROI, include booth or sponsor fee, travel, staff time, side events, and tooling in total event cost.

Does this help with Salesforce event ROI tracking? 

Yes. Use the output to pressure-test the Salesforce report you need: event cost, meetings, qualified opportunities, sourced pipeline, influenced pipeline, cost per opportunity, and closed-won cohort. The calculator is the model; Salesforce is where the proof should live.
