How we calculate
Hypothetical illustration. Northwind Analytics and Harborline Summit are fictional. The rates are not industry benchmarks and they are not taken from Trakt. Amounts are US dollars and are not converted.
Method
- The estimate uses four numbers: total event cost, leads captured, your lead-to-customer rate, and average deal value. Cost is the booth or sponsorship, travel, shipping and build, swag and hosted meetings, and loaded staff time, added into one figure.
- Expected customers are leads captured times the lead-to-customer rate. Expected revenue is those customers times average deal value. ROI is expected revenue minus cost, divided by cost. The estimate counts every captured lead, including leads with no source.
- The advanced breakdown multiplies captured leads by the tracked-source share first. A tracked lead came through a booth QR code, a UTM link, or a meeting link. The same rate and deal value then apply only to that subset.
- A cost split can replace the total inside the breakdown. Qualification, opportunity, and close can replace the lead-to-customer rate inside the breakdown, and then pipeline is reported beside ROI. Pipeline is not a return. Neither option changes the estimate. A work email shows the breakdown for the numbers you typed and sends it, with notes computed only from those inputs.
Expected revenue is a forecast, not closed revenue. When customers close, replace the rate with the rate you saw on leads that still have the event on them. Method published 20 October 2026.
Formula
Basic estimate. It counts every captured lead. expected customers = leads captured × lead-to-customer rate expected revenue = expected customers × average deal value ROI = (expected revenue - total event cost) / total event cost Advanced breakdown. It keeps only leads with a tracked source. tracked leads = leads captured × tracked-source share expected customers = tracked leads × lead-to-customer rate expected revenue = expected customers × average deal value ROI = (expected revenue - total event cost) / total event cost
Cost per tracked lead is cost divided by tracked leads. Cost per expected customer is cost divided by expected customers. Break-even customers are cost divided by average deal value. The break-even lead-to-customer rate is that customer count divided by tracked leads. If cost is zero, ROI is undefined.
Advanced event cost = booth + travel + shipping + swag + staff time advanced lead-to-customer rate = qualification rate × opportunity rate × close rate pipeline created = tracked leads × qualification rate × opportunity rate × average deal value
Worked example
Northwind Analytics is a fictional company. Harborline Summit is a fictional event. The rates were chosen so the arithmetic is easy to check by hand. They are not a claim about what conferences return.
Total cost $25,000: a $12,000 booth, $4,500 of travel, $1,500 of shipping, $1,000 of swag, and $6,000 of staff time (2 people × 3 days × $1,000 loaded day rate). Those lines are optional. Left off, both tiers use $25,000.
100 leads × 5% = 5 customers. 5 × $20,000 = $100,000. $100,000 − $25,000 = $75,000. $75,000 / $25,000 = 300% ROI. That estimate is on the page before any email. It counts leads with no source.
Tracked-source share 40% leaves 40 tracked leads. 40 × 5% = 2 customers. 2 × $20,000 = $40,000. $40,000 − $25,000 = $15,000. $15,000 / $25,000 = 60% ROI. The 60 untracked leads are not in that revenue. Cost per tracked lead is $625. The show covers its advanced cost at 1.25 customers, a 3.125% lead-to-customer rate on those 40 tracked leads.
The 5% rate is also 50% qualified × 50% opportunity × 20% close. Those stages are optional. Left off, the breakdown uses the stated rate.
Estimate
Advanced breakdown
A tracked source is written at capture. Put a QR code on the booth that opens a UTM-tagged link, and send meeting invites through a link with the same campaign name. The trade show UTM parameters guide is the naming. Trakt’s event attribution keeps that source on the lead when a later visit would otherwise overwrite it.
How do you calculate ROI for a B2B conference?
Multiply leads captured by your lead-to-customer rate and by average deal value, subtract the total event cost, and divide by that cost. That estimate counts every captured lead. The advanced breakdown multiplies by the tracked-source share first, so only leads from a booth QR code, a UTM link, or a meeting link stay in the revenue. Expected revenue is a forecast. Closed revenue replaces it once customers that still carry the event source actually close.
What should be included in trade show cost?
Booth or sponsorship, travel and lodging, shipping and build, swag and hosted meetings, and loaded staff time, added into one total. Leaving staff time out makes an expensive show look cheap. The advanced inputs can split that total. The estimate still uses the one number.
Why not count every badge scan in conference ROI?
A badge scanner exports a name and an email. It does not write a source. The estimate does count those leads, and it says so. The advanced breakdown keeps only the tracked-source share. Revenue you cannot tie back is not ROI you can defend.
What is a good conference ROI?
This page does not publish a good number, a typical number, or a Trakt customer average. Compare the show with your other channels using the same formula and your own rates. On the advanced breakdown, the break-even lead-to-customer rate is computed on tracked leads only.
Do I need to leave an email to see the result?
No for the estimate. The four-field result, the formula, and this worked example are on this page. Yes for the advanced breakdown of the numbers you type: a work email shows that breakdown here and sends the same figures, plus notes computed from those inputs, as a CSV. An optional attribution tip is a separate checkbox, and it is unticked. The breakdown sends either way.
