Trade show ROI calculator: the only formula you need
Most trade show ROI models are theater. They multiply "impressions" by imaginary conversion rates and arrive at a number that would never survive a CFO audit. Here's the formula that does.

The only formula that matters
Trade show ROI = (Pipeline generated × Win rate × Gross margin) ÷ All-in show cost
Every other formula is lying to you - usually by substituting "leads" for "pipeline," or by ignoring the all-in cost. Both substitutions inflate the number by 3-5×.
Cost per lead benchmarks
Before you can calculate ROI, you need clean inputs. Cost per lead (CPL) is the foundational input - everything else flows from it.
| Booth type | Typical CPL |
|---|---|
| Standard 20×20 w/ swag + demos | $140 - $280 |
| 20×20 with a caricaturist | $80 - $140 |
| 20×20 with a coffee bar | $60 - $100 |
| 20×20 with a headshot lounge | $20 - $35 |
The activation you choose is the single biggest lever on CPL - larger than booth size, location, or staffing.
The attribution window
Most booth ROI models use a 90-day window. That's too short. Enterprise trade-show leads typically close in the 6-9 month range - which means if your ROI meeting is 60 days post-show, you're looking at roughly 15% of the eventual pipeline.
Use a rolling 12-month attribution window for trade show ROI. Report pipeline quarterly, not after the show.
A worked example
Real numbers from an AWS partner we ran a lounge for at a 3-day Las Vegas show in late 2025:
- All-in booth cost (space, build, travel, activation): $185,000
- Opt-in, named leads captured: 812
- Cost per lead: $228 total ($22/lead attributable to the lounge)
- SQLs (qualified by AE within 30 days): 94
- Closed-won within 12 months: 19 deals
- Average contract value: $45,000
- Pipeline attributed: $855,000
- Gross margin: 72%
- ROI = ($855,000 × 72%) / $185,000 = 3.33×
That's a real, defensible 3.3× return on the show - the kind of number that keeps your booth on next year's calendar.
Three numbers that kill a booth
- CPL over $150. If you're paying more than $150/lead at a major show, your activation is wrong - not your booth.
- SQL rate below 8%. If fewer than 8% of your trade show leads become SQLs, you're capturing the wrong people. Tighten your qualification at the scan.
- Win rate below 15%. Trade show leads should win at or above your average enterprise inbound rate. If they're winning at half that rate, your sales team is treating them like cold leads.
