Meetings are expensive, and this calculator makes the hidden cost visible. Enter how many people are attending, their average hourly rate, and how long the meeting runs, and it shows the total cost of everyone in the room. There is also a live mode: start the ticking counter at the beginning of a call and watch the running cost climb in real time, which is a surprisingly effective way to keep discussions focused and on schedule. Seeing that a routine hour long sync of eight people is not free but a real line item often changes how teams plan and shorten meetings. All the math happens instantly in your browser with nothing sent anywhere, so you can experiment with different sizes and durations privately and decide whether that meeting really needs to happen.
