Imagine this: you’re organizing a kickoff event for 150 people. You have a date, a rough idea of the program, and your director’s approval. Then the phone calls start coming in. Venues ask about capacity. Caterers want a budget estimate. And you’re left empty-handed.
Key figures fill that gap. They are the benchmarks you need before you even request a single quote. No guarantees, no exact figures—but a framework within which to operate. A starting point that saves you from last-minute surprises and budget overruns that, in hindsight, could have been avoided.
When it comes to corporate events, there are five key factors to consider: budget per person, space per attendee, catering ratios, planning horizons, and occupancy standards. We’ll cover each of these in detail in this article.
Three rules of thumb for using key figures: First, they are guidelines, not hard-and-fast rules. A conference held at a luxury venue in Amsterdam costs twice as much per person as the same conference held at a conference center outside the Randstad. Second, always consider the context—an event for 500 people at a festival site has different space requirements than a dinner for 50 at a restaurant. Third, use them as conversation starters: if a venue or supplier falls far outside the usual benchmarks, ask why. Sometimes there’s a good reason. Sometimes it’s a warning sign.
