A meeting cost calculator estimates the financial cost of a business meeting by multiplying the number of attendees by their average hourly salary and the meeting duration. The standard formula is: Cost = Attendees × (Annual Salary ÷ 2,080) × Duration in hours. For example, an 8-person meeting where attendees earn $80,000/year lasting 1 hour costs approximately $308 in salary — or around $400 including employer overhead.
How to Calculate Meeting Cost: The Formula
The standard method for calculating the cost of a business meeting is based on attendee salaries. Every minute a person spends in a meeting is a minute they are not doing something else — and that time has a measurable price.
The figure 2,080 represents the standard number of working hours per year (52 weeks × 40 hours). This converts annual salary into an hourly rate. To get the true organisational cost, add 25–40% to account for employer overhead: pension contributions, benefits, office space, equipment, and management time.

Meeting Cost Benchmarks: What Is Normal?
How does your meeting cost compare to industry norms? These benchmarks are based on published research from Atlassian (2024), Microsoft WorkLab (2023), and Bain & Company.
For a company of 50 professionals earning an average of €60,000/year, spending 31 hours/month in meetings with 30% wasted:
- Monthly meeting hours total: 50 × 31 = 1,550 hours
- Unnecessary hours: 1,550 × 30% = 465 wasted hours/month
- Salary cost of waste at €29/hr: €13,485/month
- Annual cost of unnecessary meetings: €161,820/year
For a 200-person organisation, this figure typically exceeds €600,000 per year — before overhead multipliers.
Meeting Cost by Meeting Type
Not all meetings cost the same. Here is a typical cost breakdown by meeting type, based on a team of 8 professionals earning €60,000/year average:
| Meeting Type | Typical Attendees | Typical Duration | Salary Cost | With 30% Overhead |
|---|---|---|---|---|
| 1-on-1 check-in | 2 | 30 min | €29 | €37 |
| Team standup | 6 | 15 min | €43 | €56 |
| Project status meeting | 8 | 1 hour | €231 | €300 |
| Department all-hands | 25 | 1 hour | €721 | €937 |
| Company all-hands | 100 | 2 hours | €5,769 | €7,500 |
| Leadership offsite | 10 | 8 hours | €1,154 | €1,500 |
Salary estimates above use €60,000/year average (€28.85/hour). Adjust the calculator above for your team's actual compensation.
5 Ways to Reduce Meeting Costs Starting This Week
Knowing the cost is only the first step. Here are the five highest-impact changes you can make immediately:
- Make the cost visible in real time. When participants see a running cost during a meeting, average meeting length decreases by 12–18%. Tools like Calwise display this automatically via a browser overlay in Google Calendar and Outlook.
- Require a written agenda 24 hours before. No agenda, no meeting — as a policy, not a suggestion. Meetings with structured agendas run 37% shorter and produce more actionable outputs.
- Limit attendees to 7 or fewer. Bain & Company research shows that for every person added beyond 7, decision-making effectiveness drops by ~10%. Invite only those needed for the decision.
- Switch 60-minute defaults to 50 minutes. A single calendar settings change removes 17% of meeting time organisation-wide, with no cultural change programme required.
- Cancel 25% of recurring meetings this quarter. Most recurring meetings outlive their original purpose within 90 days. A 30-minute audit of your recurring calendar will typically surface 25–40% that can be eliminated immediately.
Meeting Cost Calculator Tools: Comparison

The difference between a one-time calculator (like this page or meetingcostcal.com) and a real-time platform (like Calwise) is the difference between knowing what meetings could cost and knowing what they actually cost — for every meeting, automatically, tracked over time by department.
Frequently Asked Questions
How do you calculate the cost of a meeting?
The standard formula: Attendees × (Annual Salary ÷ 2,080) × Duration (hours). Divide annual salary by 2,080 to get the hourly rate (52 weeks × 40 hours). Multiply by the number of attendees and the meeting length. Add 25–40% overhead to get the full organisational cost.
Example: 8 people, €60,000 average salary, 1-hour meeting = 8 × €28.85 × 1 = €231 salary cost. With 30% overhead: €300 total.
What is the average cost of a one-hour business meeting?
For a typical 6–8 person team meeting with professionals earning €50,000–€80,000/year, a one-hour meeting costs between €145 and €310 in salary cost alone. Add 30% overhead and the range rises to €190–€400.
Senior leadership team of 8 people earning €120,000–€150,000/year: a one-hour meeting costs €460–€580 including overhead.
How much do unnecessary meetings cost per year?
According to Atlassian State of Teams 2024, knowledge workers spend 31 hours/month in meetings, with 30%+ unnecessary. For a 100-person company at €65,000/year average salary:
- Monthly meeting hours: 3,100 hrs
- Unnecessary hours: 930 hrs
- Monthly cost at €31/hr: €28,830
- Annual cost of meeting waste: €345,960
For 500 people, this exceeds €1.7 million per year. Harvard Business Review estimates US businesses collectively lose $37 billion annually to unproductive meetings.

How can I reduce the cost of meetings?
The five highest-ROI actions: (1) make the cost visible in real time — this alone reduces meeting length by 12–18%; (2) require a written agenda before any meeting is confirmed — meetings with agendas run 37% shorter; (3) enforce a 7-person attendee limit — effectiveness drops ~10% per additional person beyond 7; (4) replace status updates with async communication (Loom, Slack); (5) audit and cancel recurring meetings quarterly — most outlive their purpose within 90 days.
Does this calculator work for any currency?
Yes. Enter any currency amount in the "Average Annual Salary" field and the result will be in that currency. The calculator works with any numeric salary figure — whether EUR, USD, GBP, or any other currency. The percentage-based formula is currency-agnostic.
