The Basic Formula
At its core, calculating meeting cost is simple multiplication. You need three inputs: how many people are in the room, what they earn, and how long the meeting lasts.
The formula:
Meeting Cost = (Sum of all attendees' hourly rates) × Meeting duration in hours
To convert an annual salary to an hourly rate, divide by 2,080 — the standard number of working hours in a year (40 hours per week × 52 weeks).
Step-by-Step Calculation
- List all attendees and their approximate annual salaries. If you don't know exact figures, use industry averages for each role.
- Convert each salary to an hourly rate by dividing by 2,080. A $100,000 salary becomes $48.08/hour.
- Sum the hourly rates to get the total meeting burn rate per hour.
- Multiply by the meeting duration in hours (convert minutes to hours by dividing by 60).
Worked Example
Consider a typical product planning meeting with the following attendees:
- 1 Product Manager — $130,000/year ($62.50/hr)
- 1 Engineering Manager — $160,000/year ($76.92/hr)
- 4 Senior Engineers — $150,000/year ($72.12/hr each, $288.46/hr total)
- 1 Designer — $120,000/year ($57.69/hr)
- 1 Data Analyst — $110,000/year ($52.88/hr)
Total hourly burn rate: $62.50 + $76.92 + $288.46 + $57.69 + $52.88 = $538.45 per hour.
For a 90-minute meeting: $538.45 × 1.5 = $807.68 in direct salary cost.
If this meeting recurs weekly, that is $807.68 × 52 = $41,999 per year — just in salary. The true cost, as we will see below, is significantly higher.
Accounting for Total Compensation
Salary is only part of what an employee costs. Employers also pay for benefits, payroll taxes, and other compensation elements that don't appear on a paycheck but are very real expenses.
The standard multiplier used in workforce planning is 1.25x to 1.4x base salary, depending on the benefits package and location:
- Payroll taxes (Social Security, Medicare, unemployment insurance): approximately 7.65-10% of salary
- Health insurance: the average employer contribution for family coverage is over $16,000 per year according to the Kaiser Family Foundation
- Retirement contributions: typical 401(k) matches add 3-6% of salary
- Other benefits: paid time off, disability insurance, life insurance, professional development budgets
Applying a conservative 1.3x multiplier to our example: $807.68 × 1.3 = $1,049.98 per meeting, or $54,599 per year for a weekly recurrence.
The Overhead Factor
Beyond compensation, every employee-hour carries a share of the company's operating costs: office space, utilities, equipment, software licenses, IT support, and management overhead. These are sometimes called "fully loaded" costs.
In commercial real estate markets, a single desk can cost $5,000-$15,000 per year. Software and equipment add another $3,000-$8,000 per employee annually. When divided across working hours, these costs add $4-$12 per person per hour to the meeting cost.
For our 8-person, 90-minute meeting, overhead adds roughly $48-$144 on top of compensation costs.
The Context-Switching Tax
Perhaps the most significant hidden cost of meetings is what happens around them, not during them. Research by Gloria Mark at the University of California, Irvine found that it takes an average of 23 minutes and 15 seconds to return to focused work after an interruption.
This means a one-hour meeting doesn't consume just one hour of productive time. It consumes:
- 5-10 minutes of preparation (finding the room, pulling up documents, mental context loading)
- 60 minutes of meeting time
- ~23 minutes of refocusing time afterward
That is approximately 88-93 minutes of productive time per attendee for a "one-hour" meeting. For 8 attendees, the total productive time consumed is 11-12.4 hours — not 8 hours.
Applied to our example: if we cost the meeting at the full 93 minutes of impact per person rather than just the 90 minutes in the room, and include the refocus cost for all 8 attendees, the effective time cost grows by approximately 25-30%.
The Opportunity Cost
Every hour spent in a meeting is an hour not spent on other work. For engineers, that might mean code that doesn't get written. For salespeople, deals that don't get closed. For product managers, user research that doesn't happen.
Opportunity cost is the hardest component to quantify because it depends on what each person would have done instead. But it is often the largest cost of all. A senior engineer who bills clients at $250/hour or who is building a feature expected to generate $500,000 in revenue has a very different opportunity cost than someone in a support role during a quiet period.
As a rough heuristic, many organizations use a 2x multiplier on salary cost to approximate the fully-loaded, opportunity-inclusive cost of a meeting. Our $807.68 salary-only meeting becomes approximately $1,615 in total economic impact.
Putting It All Together
Here is a summary of the cost layers for our example 8-person, 90-minute product planning meeting:
- Direct salary cost: $807.68
- With benefits (1.3x): $1,049.98
- With overhead: ~$1,146
- With context-switching: ~$1,489
- Estimated total economic impact (2x salary): ~$1,615
If that meeting happens weekly, you are looking at $42,000-$84,000 per year depending on which cost factors you include.
The point is not that this meeting should be cancelled. It might be the most valuable 90 minutes of the week. The point is that you should know what it costs so you can make that judgment intentionally.

Open the CalculatorHow to Present Meeting Cost Data
If you are building a case for reducing meetings at your company, here are some tips for presenting the data effectively:
- Lead with annual cost, not per-meeting cost. "$42,000 per year" is more impactful than "$808 per meeting" — it makes the recurring nature of the expense impossible to ignore.
- Compare to tangible alternatives. "$42,000 is the cost of a junior developer" or "That's our annual cloud infrastructure bill" gives context that abstract numbers lack.
- Propose specific changes, not blanket elimination. "Let's cut this meeting from 90 to 50 minutes and make it biweekly" is more actionable than "We should have fewer meetings."
- Share the calculator link. Let people explore the numbers themselves. Self-discovery is more persuasive than being told.
