Our ROI calculator forecasts whether a trade show is likely to pay for itself before you commit to it.
Enter the cost of exhibiting, number of qualified leads expected, your own conversion rate and your average deal value. The calculator returns a projected pipeline figure, ROI percentage, and the number of qualified leads to break even.
Every figure in the result comes from numbers you provide, not a borrowed industry average.
What the exhibition ROI calculator does
The calculator turns the formula found here for measuring ROI into something you can run against a specific show. Use this before the budget is committed, rather than after the stand has been packed away.
It takes the same two-sided view of return that any honest measurement needs:
1. The full cost of taking part on one side
2. The qualified pipeline that exhibiting is likely to generate on the other.
Rather than giving you a generic benchmark, it asks for numbers that are specific to your business and your show. It then runs the calculation in front of you so you can see exactly how the result was reached.
The inputs you will need
Five figures are enough to produce a meaningful forecast.
On the cost side, you will need:
• The floor space fee.
• The cost of the stand itself including design, build or hire and graphics.
• Your staff travel, accommodation and subsistence for the show.
• A general allowance for lead capture technology, pre-show marketing and post-show follow-up.
On the value side, you will need:
• The number of qualified leads you realistically expect the stand to produce.
• The conversion rate you typically see from a qualified lead to a closed deal.
• Your average deal value.
Conversion rate is the figure worth taking from your own CRM, since it moves the result more than any other input.
How the forecast is calculated
The calculation runs in two steps.
First, the cost inputs are added together to give the total investment. Second, the number of qualified leads multiplied by your conversion rate gives a projected number of deals. This figure is multiplied by your average deal value to give a projected pipeline value.
The return on investment is pipeline value minus total investment, divided by total investment, expressed as a percentage. Exactly the formula set out in our guide to measuring trade show ROI.
The calculator also shows the number of qualified leads you need to break even. It calculates this from your stated conversion rate and deal value.
How to read your result
A positive percentage means the show is forecast to return more than it costs at the assumptions you have entered, and a negative one means it is not, at least not on the numbers you have put in. The break-even lead count is often the more useful figure of the two, because it turns an abstract percentage into a concrete target your team can judge realistically against what the show is likely to deliver.
If that figure looks achievable against what similar shows have produced for you before, the case for exhibiting is reasonably strong. If it looks high against your team’s experience of the show or the sector, that is worth raising before the budget is signed off, not after.
The assumptions and limits to keep in mind
Every figure the calculator returns is only as reliable as the numbers you enter, and the three you supply yourself, lead volume, conversion rate and deal value, are forecasts rather than facts until the show has actually happened.
The tool deliberately does not pre-fill a conversion rate or a typical deal value, because no externally published figure for either is reliable enough across sectors and shows to be worth borrowing. The calculator also does not account for revenue that closes well outside the window you might naturally judge a show by.
So a result that looks marginal on a short view can look very different once the full sales cycle has played out, which is the attribution point covered in our main ROI guide.
What to do once you have your number
Treat the result as the start of a conversation rather than the end of one.
A strong projected ROI is a reasonable basis to commit budget to a show, provided the lead and conversion assumptions behind it are ones your team genuinely believes it can hit.
A weak or negative one is worth investigating before it rules a show out, since it may reflect a stand, message or follow-up process that needs to improve rather than a show that is not worth attending.
Either way, save the assumptions you used, run the same numbers again after the show, and compare the forecast against what actually happened. That comparison, repeated over a few shows, will tell you more about your own realistic conversion rate than any industry figure ever could.
Frequently asked questions
How accurate is the exhibition ROI calculator?
The calculation itself is simple arithmetic and will always be accurate. The forecast is only as accurate as the lead volume, conversion rate and deal value you enter, which is why the tool asks for your own figures rather than supplying default industry numbers.
What conversion rate should I use for trade show leads?
Use your own historical conversion rate from qualified lead to closed deal, taken from your CRM if you have one. There is no reliable, UK-specific published benchmark for trade show conversion rates, so an external figure would be a guess dressed up as data.
What does the break-even lead count mean?
It is the number of qualified leads you would need to capture, at your stated conversion rate and deal value, for the show to cover its full cost. It turns the ROI percentage into a concrete, plannable target for your team on the day.
Can I use this calculator for a show I have already exhibited at?
Yes. Replace the forecast lead, conversion and deal value figures with what actually happened, and the same calculation gives you the real ROI for that show, which is the figure worth comparing against your original forecast.
