Meeting Cost Calculator

What this tool does

Meeting Cost Calculator converts attendee count, average annual salary and meeting duration into an estimated real-dollar cost for that meeting, plus what it would add up to over a year if held weekly, making an often-invisible cost visible.

A meeting’s cost in salaried time is easy to overlook, no invoice gets generated, no line item appears on a budget, but six people in a one-hour meeting is genuinely six person-hours of paid time, every time it happens.

This calculator converts attendee count, average annual salary and meeting duration into a concrete estimated cost, plus what that adds up to over a year if the same meeting repeats weekly, making an often-invisible cost visible and easier to weigh against its actual value.

How to use Meeting Cost Calculator

1. Enter the number of attendees.
2. Enter their average annual salary and typical working hours per year.
3. Enter the meeting’s duration in minutes.
4. Review the estimated cost, including the annualised figure if held weekly.

Tips for better results

• This hourly-rate approximation (salary ÷ working hours per year) doesn’t include benefits, overhead, or the opportunity cost of what attendees could otherwise be doing, the real cost is typically higher than this baseline figure.
• The "if held weekly, per year" figure is often the most useful one, a single meeting’s cost can look small in isolation, but a recurring weekly meeting’s annual total frequently reveals a genuinely significant expense.
• Use this figure as a conversation starter for whether a recurring meeting’s value justifies its cost, not as a precise accounting figure, it’s intentionally a simplified estimate.
• 2,080 hours per year (40 hours/week × 52 weeks) is a common default for working hours per year; adjust it if your organisation uses a different standard.

Common use cases

• Making the case for shortening, combining, or cancelling an unnecessary recurring meeting.
• Estimating the real cost impact of adding more attendees to a meeting before scheduling it.
• Building awareness within a team about the cumulative cost of recurring meetings.
• Quickly ballparking a meeting’s cost when deciding whether it’s worth everyone’s time.

Common mistakes to avoid

• Treating the output as a precise accounting figure rather than a simplified estimate, it deliberately excludes benefits, overhead and opportunity cost, all of which push the real number higher.
• Only looking at a single meeting’s cost and missing the much larger annualised figure for a recurring meeting, which is usually the more meaningful number for deciding whether to keep, shorten, or cancel it.
• Using an unrealistic average salary figure for a genuinely mixed-seniority group of attendees, consider a true average (not just a guess) for a more representative estimate.
