Live Meeting Cost Calculator
Watch the real cost of a meeting tick up second by second. Enter attendees, salary, and length to see the live cost, the full-meeting cost, the annualized cost if it recurs, and what that money could buy.
How to use this tool
- Enter the number of attendees and the average annual salary per person.
- Set the meeting length in minutes and pick how often it recurs.
- Press Start to watch the cost accrue live, second by second.
- Read the full-meeting cost, the annualized cost, and the “what this buys” line.

Most “meeting cost calculators” just multiply a few numbers and stop. This one makes the cost visceral: hit Start and the dollar figure ticks up in real time, the same way the meeting is actually burning payroll. It is built for the person who wants to drop a hard number into a “does this need to be a meeting?” conversation.
Beyond the live timer it adds two things existing tools miss: a recurring-meeting projection (a one-hour weekly sync is really 52 of these a year) and a “what this buys” framing that converts the cost into coffees and days of an engineer’s salary — because $3,400 means more when it’s 4 days of headcount. Share the URL and your teammate sees the exact same numbers.

How it works
The Live Meeting Cost Calculator shows the financial cost of a meeting ticking up in real time as the meeting runs. Enter the number of attendees, their average annual salary, and the planned meeting length, and the counter starts counting dollars per second.
The tool displays the cost at the current moment, the projected full-meeting cost, and the annualized cost if the meeting recurs at the same frequency (daily, weekly, monthly). It also shows a comparison of what that money could alternatively fund.
Use it before or during a meeting to make the cost tangible, justify shorter agendas, or identify recurring meetings that may not be worth their cost. It is most effective displayed on a shared screen during planning sessions.
Worked example
Calculate the cost of a 1-hour all-hands with 20 people
- Set Attendees to 20 and Average salary to $80,000.
- Set meeting length to 60 minutes.
- Start the timer.
- Watch the cost tick up — at $0.64 per second it reaches about $769 at the 60-minute mark.
- Check the annualized cost if the meeting is weekly: roughly $40,000 per year.
A weekly 1-hour all-hands with 20 people at average $80k salary costs approximately $40k per year in labor alone.
Common mistakes to avoid
- Using only base salary without overhead multiplier, which understates the true cost by 25-50%.
- Setting all attendees to the same high-earner salary when the group includes a mix of seniority levels.
- Framing the result as a reason to cancel all meetings rather than as a tool to right-size agendas and attendance.
Key terms
- Fully loaded cost
- An estimate that includes salary plus employer overhead (benefits, taxes, office space), typically 1.25-1.5x base salary.
- Annualized cost
- The yearly total if a single meeting repeats on a chosen cadence (daily, weekly, etc.).
- Opportunity cost
- The value of what attendees could have produced with the same time instead of attending the meeting.
Frequently asked questions
- How is the per-second cost calculated?
- Each attendee’s annual salary is divided by 2,080 working hours per year to get an hourly rate, then by 3,600 to get cost per second, summed across all attendees. Salary is a stand-in for fully-loaded cost; real loaded cost (benefits, overhead) is often 1.25–1.4× higher.
- What does the annualized number mean?
- If you mark the meeting as recurring, the tool multiplies the full-meeting cost by how often it happens in a year (weekly × 52, monthly × 12, daily × 260 working days). A modest weekly standup can quietly cost tens of thousands of dollars per year.
