How It Works
How to Calculate Meeting Cost
The true cost of a meeting is the duration multiplied by the number of attendees and their average hourly compensation.
Formula
Duration = End Time - Start Time (in hours)
Meeting Cost = Duration x Attendees x Average Hourly Rate
Worked Example
A meeting from 10:00 to 11:30 with 5 attendees averaging $50/hr.
start_hour = 10start_min = 0end_hour = 11end_min = 30attendees = 5avg_hourly = 50
- 01Duration = (11:30 - 10:00) = 90 minutes = 1.5 hours
- 02Person-hours = 1.5 x 5 = 7.5 hours
- 03Meeting cost = 7.5 x $50 = $375.00
