Enter how many people attend, their average hourly rate and how long the meeting runs. The cost updates instantly, and you can start the live timer during the meeting itself.
A fully loaded rate is more honest than raw salary: take the annual salary, add roughly 25-35% for employer taxes, benefits and overhead, then divide by about 1,800 working hours. Using bare salary understates a meeting's true cost by a third.
Start it at the beginning of a real meeting and the cost ticks upward second by second at the rate you entered. Projected on a screen it is a famously effective way to keep a status meeting short.
It multiplies the single-meeting cost by how often the meeting recurs in a year — 52 for weekly, 26 for fortnightly, 12 for monthly. A one-hour weekly meeting with eight people is usually the number that surprises people most.
