We divide the average hourly rate by 60 to get the cost per minute. We then multiply this by the duration of the meeting and the number of attendees. For the annual cost, we multiply the single meeting cost by your monthly frequency, and then by 12 months.

If you are an agency, use your billable hourly rate (e.g., 100€ - 150€), because every hour spent in an internal meeting is an hour you cannot bill to a client. If you are a product team, use the gross salary cost per employee divided by their actual working hours (usually around 40€ - 80€).
