Trade Show & Event Marketing ROI Calculator for 2026

Calculate trade show ROI, cost per lead, and cost per sale from booth costs, leads, and conversion rates.

Mathematical Audit

How Trade Show & Event Marketing ROI Is Calculated

Total event cost is compared against revenue generated by running leads through a two-stage B2B conversion funnel: lead to opportunity, then opportunity to closed sale.

Total Event Cost = Booth/Exhibit + Travel/Lodging + Staffing + Other Costs
Opportunity Count = Leads Generated × Lead-to-Opportunity %
Sale Count = Opportunity Count × Opportunity-to-Sale %
Total Revenue = Sale Count × Average Deal Value
ROI % = ((Total Revenue − Total Event Cost) ÷ Total Event Cost) × 100
Cost Per Lead = Total Event Cost ÷ Leads Generated

A 'good' trade show ROI in 2026 typically starts around 3:1 (300%), though high-margin SaaS companies often target 5:1 while hardware manufacturers may accept 2:1. Leads contacted within 2 hours of a badge scan convert at up to 400% higher rates than those followed up with a day later.

Real-World Scenario Example

"A company spends $20,000 total on a trade show, generates 200 leads, converts 30% to opportunities and 25% of those to sales worth $5,000 each."

Inputs

boothAndExhibitCost:8000
travelLodgingCost:5000
staffingCost:4000
otherCosts:3000
leadsGenerated:200
leadToOpportunityPercent:30
opportunityToSalePercent:25
avgDealValue:5000

Result

15 opportunities, roughly 3.75 closed sales, generating about $18,750 in revenue for a modest negative ROI at this conversion rate, well below the 3:1 industry benchmark.
