Trade show ROI: what to count as cost and return
A method you can defend to finance: what belongs in the cost, why to count gross profit, long sales cycles, and a worked example with made-up numbers.
Most trade show ROI figures go wrong in two places. They leave out what your own people cost, and they count revenue when they should count profit. Both make the show look better than it was, and a finance team will notice.
What goes into the cost
Count everything the show made you spend, in one currency:
- The space and the stand build, or the rental and the shipping.
- Travel, hotels and meals for everyone who goes.
- The time of your staff: hours at the show, in preparation and in follow-up, at their cost to the company.
- Your lead capture tool, giveaways and printed material.
- Marketing before the show, such as invitations and ads for the stand.
The staff line is the one that gets skipped, because nobody sends an invoice for it. Put it in anyway. If you leave it out, you are comparing the show with a version of your business that had free employees.
What counts as the return
Count the gross profit of the deals you can trace to the show, not the revenue. Gross profit is the revenue minus the cost of delivering it. Then:
ROI = (gross profit − total cost) ÷ total cost
A show that brought €100,000 in revenue at a 20% margin returned €20,000 of gross profit. If it cost €30,000, it lost money, whatever the revenue figure suggests.
A worked example (made-up numbers)
The numbers below illustrate the method. They are not a benchmark, and they are not from a real show.
| Item | Value |
|---|---|
| Total cost of the show | 12,000 |
| Leads captured | 150 |
| Close rate | 4% |
| Customers | 6 |
| Average deal value | 8,000 |
| Gross margin | 40% |
| Revenue | 48,000 |
| Gross profit | 19,200 |
| Net result (gross profit − cost) | 7,200 |
| ROI | 60% |
| Cost per lead | 80 |
| Cost per customer | 2,000 |
The same numbers give you the break-even point. Each customer brings 3,200 of gross profit (8,000 × 40%), so the show needs 12,000 ÷ 3,200 = 3.75, which means 4 customers, to pay for itself. On 150 leads that is a close rate of 2.5%.
Work the break-even out before the show. “We need four customers from this” is a target the stand team can understand. “We want a good ROI” is not.
Long sales cycles
In many trade-show industries a deal takes six or twelve months. Judging a show at the end of the week, or even at the end of the month, undercounts it. Measure the same leads again after three, six and twelve months, and report the deals that closed and the open pipeline separately.
Mistakes that make ROI look better than it is
- Counting every contact as a lead, including people who only took a pen.
- Leaving out the time of your own staff.
- Counting revenue instead of gross profit.
- Crediting the show with deals that were already in your pipeline.
- Judging the show before any deal could close.
What about brand awareness? It is real, but you cannot trace it to a deal. Count it separately and do not mix it into ROI.
Tracking the leads of a show
To do any of this you need to know which customer came from which show. Mark every lead with the show it came from, grade it the same way for the whole team, and keep one list. Later you can match the list against your CRM or your invoices.
Followbooth saves each lead with who scanned it, an A, B or C grade and the show, and exports everything to CSV, so you can count customers per show in your own sheet or CRM. The ROI guide has a calculator that runs in your browser; nothing you type is sent or stored.
The result is a clean list per show to count against. The counting of deals and revenue stays in your own CRM or sheet.
