You Can't Cut What You Can't See

"That meeting ran long." Most teams stop there.

Feeling that a meeting was unproductive is not enough. Without numbers, nothing changes. The real reason meeting costs go unchallenged is that losses are invisible — they don't show up on a budget line or a monthly statement.

But when you run the calculation, the results are often startling.

Six people, average salary of $80,000, one 60-minute weekly meeting. The direct labor cost alone runs to roughly $300 per session — and nearly $15,000 per year for a single recurring meeting. The global scale of this problem is enormous: unproductive meetings cost the world an estimated $259 billion annually, as detailed in our statistics overview. But the most actionable number is the one from your own team.

Step 1: Learn the Formula

The meeting cost formula has three inputs.

Meeting Cost = Number of Attendees × Average Hourly Rate × Duration (hours)

To convert annual salary to an hourly rate:

Hourly Rate = Annual Salary ÷ 2,080

2,080 is the standard annual working hours (40 hours/week × 52 weeks). For a fully-loaded cost that includes benefits and overhead, multiply the result by 1.25–1.4.

When your team has mixed roles and salary ranges, use an average. At this stage, rough accuracy beats false precision — the goal is to make the invisible visible, not to produce a forensic audit.

Step 2: Run the Numbers

Here's a worked example: a product team's weekly sprint review.

Setup：

• Attendees: 6
• Average annual salary: $80,000
• Duration: 60 minutes, weekly

Calculation：

1. Hourly rate: $80,000 ÷ 2,080 ≈ $38.46/hr
2. Fully-loaded rate: $38.46 × 1.3 ≈ $50/hr
3. Per-meeting cost: $50 × 6 attendees × 1 hour = $300
4. Annual cost (50 sessions): $300 × 50 = $15,000

One weekly meeting. $15,000 per year.

The Timefair Meeting Cost Calculator runs this calculation in real time as you type. Enter headcount, average salary, and duration — it instantly shows the per-session cost and the annualized figure. Try it now with your team's most frequent recurring meeting.

Step 3: Account for Hidden Costs

Direct labor is only part of the picture. Two additional costs are consistently underestimated.

Opportunity Cost

Every hour spent in a meeting is an hour not spent on other work. For an engineer, that's an hour of code not written. For a salesperson, it's a call not made. Opportunity cost is hard to measure precisely, but it's often the largest component of the true cost.

Context-Switching Cost

Research from UC Irvine shows that after an interruption, it takes an average of 23 minutes to return to full concentration. A 1-hour meeting at 2 p.m. doesn't cost just one hour — accounting for the disruption to tasks before and after, it can consume up to 3 hours of productive capacity. On meeting-heavy days, deep work becomes structurally impossible.

When you factor these in, the real cost is typically 1.5 to 2× the direct labor figure.

What to Do After You See the Numbers

Once you've calculated your meeting costs, evaluate each high-cost meeting against these four questions.

① Can this be asynchronous? Status updates, information sharing, and approval requests often don't require everyone online simultaneously. Slack, Notion, or Loom can replace a surprising number of meetings. Ask: does this require real-time presence, or is that just habit?

② Can we reduce attendees? Every person in the room who isn't directly involved in the decision is a cost with no corresponding output. "Just in case" or "FYI" invitations are expensive. Cutting even one or two attendees can reduce per-meeting cost by 15–30%.

③ Can we shorten the time block? If a meeting is scheduled for 60 minutes because that's the calendar default, try 45 or 30. Parkinson's Law applies to meetings: work expands to fill the time allotted. A shorter slot forces sharper preparation.

④ Is the goal defined before anyone joins? Specify what decision or output will exist by the end of the meeting. Meetings without a defined outcome tend to drift, run over, and produce no clear next steps — exactly the pattern that generates the $259 billion in global losses.

Summary

Visualizing meeting costs takes less than a minute. The formula is simple. The calculator does the math.

What matters is doing it. When a vague sense of waste becomes a specific dollar figure, the path forward becomes obvious. Open the Timefair Meeting Cost Calculator, find your most expensive recurring meeting, and run the numbers. That single step is often enough to change the conversation.

FAQ

Q: 会議コストはどうやって計算する？

A: 基本式は「参加人数 × 平均時給 × 会議時間」です。時給は年収 ÷ 2,080 で求め、さらに1.25〜1.4倍すると福利厚生・間接費込みの完全コストになります。Timefairの会議コスト計算ツールを使うとリアルタイムで計算できます。

Q: 会議コストを可視化すると何が変わる？

A: 感覚的な「長い」「無駄」が、具体的な金額に変わります。週1回60分の定例会議が年間100万円を超えるコストになるケースも珍しくありません。数字になることで、削減の優先度づけや上司への提案が格段にしやすくなります。

Q: 機会コストも会議コストに含めるべきか？

A: 含めることが推奨されます。参加者が会議中に生み出せなかった価値（コードのレビュー、顧客対応、資料作成など）が機会コストです。これを含めると実質的なコストは直接人件費の1.5〜2倍以上になることがあります。

Q: 会議コストを下げるために最初にすべきことは？

A: まず現状の数字を把握することです。ツールで計算してみると、コストの高い会議が自然に浮かび上がります。その中から「非同期で代替できるか」「参加者を絞れるか」を検討するのが最初のステップです。

Q: What is the simplest way to calculate meeting cost?

A: Multiply the number of attendees by the average hourly rate by the meeting duration in hours. To get the hourly rate, divide the annual salary by 2,080. For a fully-loaded cost including benefits and overhead, multiply by 1.25–1.4. The Timefair Meeting Cost Calculator does this automatically in real time.
