Meeting cost calculator

Why calculate meeting costs?

A 1-hour meeting with 10 people earning $50/hour costs $500 in salary alone, before you factor in preparation time, context-switching costs, and follow-up work. Making this cost visible helps teams decide whether a meeting is worth holding, or whether an email or async update would suffice.

This calculator uses a simple formula:

total cost = attendees × hourly rate × duration in hours

It does not include overhead multipliers such as benefits, office space, or equipment, which can increase the real cost by 1.25x to 1.5x in many organisations.

Tips for reducing meeting costs

• Keep meetings to the minimum number of attendees needed to make a decision.
• Set a hard time limit and stick to it. Most meetings can be 25 or 50 minutes instead of 30 or 60.
• Replace status updates with async tools such as Slack, email, or shared docs to free up calendar time.
• Cancel recurring meetings that no longer have a clear purpose or agenda.

The true cost of a meeting

The salary cost is only the most visible part of meeting overhead. The full cost includes:

Preparation time: Most structured meetings require preparation — reviewing documents, preparing slides, reading prior notes. For a 1-hour meeting, 15 to 30 minutes of pre-meeting preparation per attendee is common. Add that to the total and the real time cost of a 1-hour meeting with 10 people is closer to 12 to 15 person-hours.

Context-switching cost: Interrupting deep work to attend a meeting doesn't just cost the meeting time — it costs the time needed to re-enter the previous state of focus. Research by Gloria Mark at UC Irvine found that it takes an average of 23 minutes to fully regain focus after an interruption. A mid-afternoon meeting that breaks a 3-hour coding or writing session can effectively cost two hours of productive work, not one.

Follow-up time: Meetings that produce action items, decisions, or documents require follow-up. Writing meeting notes, sending summaries, and completing action items extend the real cost beyond the meeting room.

A more complete cost estimate might be:

true cost = salary cost × 1.5 (overhead) × 2 (prep + follow-up multiplier)

For a 1-hour meeting with 10 people at $100k average salary, the salary cost alone is ~$480. With overhead and prep, the true cost can exceed $1,000.

Meeting cost at scale: annual impact

The cost of a single meeting is easy to dismiss. The cost of a recurring meeting over a year is harder to ignore.

These figures use salary only. Add 30–50% for benefits and overhead and the numbers approximately double.

When a meeting is worth the cost

Not all meetings are wasteful. Some generate value that far exceeds their cost: a 30-minute decision meeting that unblocks a $500k project, a hiring interview that results in a great long-term hire, a difficult conversation that resolves a conflict that was silently degrading team output.

A meeting earns its cost when:

• A real decision needs to be made and the decision-makers are in the room
• The information cannot be communicated as effectively in writing
• Real-time collaboration generates ideas or solutions that would not emerge asynchronously
• Human connection or morale is the explicit goal

A meeting does not earn its cost when:

• It exists primarily to share information that could be a written update
• Attendees are present for the off-chance they are needed rather than because they are required
• The agenda is loose enough that the outcome could have been achieved in a 5-minute message thread
• It recurs on a schedule but often has nothing to discuss

The async alternative

The strongest tool for reducing meeting costs is not running shorter meetings — it is replacing meetings with well-structured async communication. A written update forces the author to clarify their thinking, creates a searchable record, and allows recipients to engage on their own schedule. For teams across time zones, async is often the only practical option anyway.

The question to ask before scheduling a meeting: "What is the minimum communication format that achieves the same outcome?" If the answer is an email, a Slack message, or a shared document, schedule that instead.
