How to Calculate Meeting Cost: A Complete Guide with Formula

Why You Need to Know Your Meeting Cost

Every meeting has a hidden price tag. When you gather 5 people earning $50/hour for a 1-hour meeting, that's $250 of collective salary spent — regardless of whether the meeting was productive.

According to Harvard Business Review, executives spend an average of 23 hours per week in meetings. Understanding the true cost helps organizations make smarter decisions about when a meeting is truly necessary.

The Meeting Cost Formula

The fundamental formula is straightforward:

Meeting Cost = Σ (Each Attendee's Hourly Rate × Meeting Duration in Hours)

For a simpler calculation with uniform rates:

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

Step-by-Step Example

Let's calculate the cost of a typical team standup:

• Attendees: 6 people
• Average hourly rate: $65/hour
• Duration: 15 minutes (0.25 hours)

Cost = 6 × $65 × 0.25 = $97.50 per standup

If this happens daily (5 days/week, 50 weeks/year): $97.50 × 250 = $24,375/year — just for standups!

Per-Second Real-Time Calculation

For maximum accuracy, our meeting cost calculator uses per-second tracking. The formula becomes:

Cost at time T = Σ (Hourly Rate ÷ 3600) × Seconds Elapsed

This accounts for people joining at different times and having different hourly rates — giving you the most accurate picture possible.

Multi-Currency Considerations

In global teams, attendees may have salaries in different currencies (USD, EUR, JPY, VND, etc.). Rather than converting everything to one currency, our calculator shows costs per currency group, avoiding inaccurate exchange rate assumptions.

Hidden Costs Not in the Formula

The salary cost is just the beginning. Consider these additional hidden costs:

• Opportunity cost: What productive work could attendees be doing instead?
• Context switching: Studies show it takes 23 minutes to regain focus after an interruption
• Meeting preparation: Time spent creating agendas, slides, and pre-reads
• Follow-up work: Action items, meeting notes, and recap emails
• Technology costs: Zoom, Teams, or other platform subscriptions
