Your Meetings Cost More Than You Think. Here's the Formula.

A one-hour meeting with eight people is not a one-hour meeting. It is eight person-hours of productivity consumed. At a blended cost of $75/hour (salary plus benefits plus overhead), that single meeting costs $600. If it happens weekly, that is $31,200 per year. For one recurring meeting.

The basic formula

Meeting cost = Number of attendees * Average hourly cost * Duration (hours)

Average hourly cost includes more than salary. The fully loaded cost of an employee is typically 1.3x to 1.5x their salary, accounting for benefits, payroll tax, office space, equipment, and administrative overhead.

function meetingCost(attendees, avgSalary, durationMinutes) {
  const hourlyRate = avgSalary / 2080; // 2080 working hours/year
  const loadedRate = hourlyRate * 1.4;  // Benefits multiplier
  const hours = durationMinutes / 60;
  return attendees * loadedRate * hours;
}

// 8 people, $100K avg salary, 1 hour
meetingCost(8, 100000, 60); // $538.46

The hidden costs

The dollar figure above only captures direct time cost. The real impact is worse.

Context switching. Studies consistently show that it takes 15-25 minutes to regain deep focus after an interruption. A 30-minute meeting in the middle of a coding session does not cost 30 minutes. It costs 30 minutes plus 20 minutes of ramp-up time on either side. That 30-minute meeting actually consumes 70 minutes of productive time.

Calendar fragmentation. A meeting at 10 AM and another at 2 PM fragments the day into three short blocks. Developers need 2-4 hour uninterrupted blocks for complex work. Two meetings can destroy an entire day's deep work capacity even though they only occupy 2 hours of calendar time.

Preparation time. Most meetings require preparation: reading documents, reviewing data, preparing slides. This time is real but almost never counted in meeting cost calculations. Add 15-30 minutes per attendee for any meeting that requires informed participation.

The opportunity cost

Every hour in a meeting is an hour not spent on something else. For a senior engineer at a company where engineering is the core value creator, that hour might be worth far more than the loaded hourly rate.

If a senior engineer's work generates $500/hour in business value (a reasonable estimate at many tech companies), then pulling them into a meeting where they contribute marginally costs the company $500 in opportunity cost, not just $75 in salary cost.

This is why Jeff Bezos' "two pizza rule" exists. Small meetings with only essential attendees minimize aggregate cost. Every additional person who attends "just in case" or "for visibility" adds their full loaded cost to the bill.

Calculating recurring meeting costs

Recurring meetings compound dramatically:

function annualMeetingCost(attendees, avgSalary, durationMinutes, frequency) {
  const perMeeting = meetingCost(attendees, avgSalary, durationMinutes);
  const frequencies = {
    'daily': 260,
    'weekly': 52,
    'biweekly': 26,
    'monthly': 12
  };
  return perMeeting * (frequencies[frequency] || 52);
}

// Weekly 1-hour standup, 10 people, $90K avg
annualMeetingCost(10, 90000, 60, 'weekly');
// ~$31,269 per year

A company with 100 employees averaging 10 hours of meetings per week is spending roughly $3.5 million per year on meetings. Some of that is necessary. But how much?

The audit framework

Here is how I evaluate whether a meeting is worth its cost:

1. Does this meeting have a clear decision to make? If yes, it is probably worth having. If no, it might be an email.

2. Are all attendees required for the decision? Remove anyone who is there "for awareness." Send them notes afterward.

3. Could this be asynchronous? Status updates, information sharing, and feedback that does not require real-time discussion should be written documents.

4. Is the cadence right? A weekly meeting that only has meaningful content biweekly is wasting 50% of its cost.

5. Is the duration right? Parkinson's Law applies to meetings: they expand to fill the time allocated. A 30-minute meeting often accomplishes what a 60-minute meeting does with less drift.

Making the case to leadership

If you want to reduce unnecessary meetings at your company, do not argue about productivity abstractly. Calculate the dollar cost and present it as a business metric. "$156,000 per year on weekly all-hands that could be a written update" is a concrete number that gets attention.

For running these calculations quickly, I built a meeting cost calculator at zovo.one/free-tools/meeting-cost-calculator. Enter the attendee count, average salary, duration, and frequency, and it shows the per-meeting and annual cost. Seeing the number changes how you think about scheduling.
