How to calculate the true cost of a meeting (formula + what counts as 'good')

The fastest way to calculate the cost of a meeting: multiply the number of attendees by each person's loaded hourly rate, then multiply by the meeting length in hours. A loaded hourly rate is annual salary divided by 2,080 working hours, times roughly 1.3 to cover benefits and overhead. Six people at a $120,000 salary in a one-hour meeting costs about $450, not the $58 per person you'd get from the gross-pay shortcut. The rest of this guide turns that one line into a formula you can defend, then answers the harder question almost no calculator touches: what makes a meeting's cost actually worth it.

The formula in one line

Every credible meeting-cost calculator runs the same core arithmetic. The differences are in how honest the hourly rate is.

The number 2,080 is the standard count of paid working hours in a US year: 52 weeks x 40 hours. Dividing salary by it converts a yearly figure into an hourly one. Skip the overhead multiplier and you systematically understate the cost by 25 to 40 percent, because salary is not what an employee actually costs the company.

A widely cited rule of thumb from MIT senior lecturer Joseph Hadzima puts the true cost of an employee at 1.25 to 1.4 times base salary once you add payroll taxes, benefits, and the basics of having someone on staff. Use 1.3 if you want one number; use 1.4 for senior or technical roles with expensive tooling.

A worked example, step by step

Say a recurring 60-minute status meeting has six attendees: two managers at $150,000, three specialists at $110,000, and one director at $200,000.

1. Convert each salary to an hourly rate: divide by 2,080. That gives roughly $72, $53, and $96 per hour.
2. Apply the overhead multiplier of 1.3: about $94, $69, and $125 per loaded hour.
3. Sum the loaded hourly rates for everyone in the room: (2 x 94) + (3 x 69) + (1 x 125) = $520 per hour.
4. Multiply by duration. At one hour, this meeting costs about $520 each time it runs.
5. Multiply by frequency. Weekly for a year, counting about 48 weeks the meeting actually runs after holidays and PTO rather than all 52, is roughly $25,000 a year for one recurring meeting.

Why the number is bigger than it feels

People underestimate meeting cost because they price their own time and forget they multiplied it by everyone else's. The aggregate data is the gut check.

And the load is not shrinking. Microsoft's analysis of its own telemetry found that the meeting habit has gotten structurally messier, which makes per-meeting discipline matter more, not less.

What counts as a 'good' meeting cost

A dollar figure is meaningless without a yardstick. A $520 meeting is cheap if it prevents a $50,000 mistake and outrageous if it could have been a three-line message. Here is a practical way to judge whether a meeting earns its price.

1. Cost-to-decision ratio

A good meeting produces a decision, a plan, or a shared understanding that could not have been reached asynchronously. Divide the meeting cost by the number of real decisions or unblocked items that came out of it. A $520 meeting that closed three blocking decisions cost about $170 per decision, which is fine. A $520 meeting that produced 'let's circle back' produced nothing, so its effective cost is infinite.

2. The async test

Before booking, ask whether the same outcome could be reached with a document, a recorded update, or a short thread. If yes, the meeting's true cost is not the formula figure, it is pure waste, because you are paying for a worse version of a free option. Reserve synchronous time for genuine debate, negotiation, sensitive feedback, and relationship-building, which are the things async actually handles poorly.

3. The right-people ratio

Cost scales linearly with headcount, so the single biggest lever is who is in the room. A meeting where half the attendees never speak and have no decision rights is roughly twice as expensive as it needs to be. A 'good' meeting has every attendee either contributing or making a call. Optional attendees should be genuinely optional, with notes shared after.

How to cut the cost without cutting the meeting

You don't always need to cancel. Most meeting waste comes from four fixable leaks, in rough order of impact.

• Trim the guest list. Because cost is linear in headcount, removing two non-deciding attendees from a recurring weekly meeting is often the largest single saving available.
• Shorten the default. Move recurring meetings from 60 to 45 or 30 minutes. Work expands to fill the slot, so the slot is the lever.
• Require an agenda or cancel. No agenda usually means no clear purpose, which is the strongest predictor of a wasted meeting.
• Stop paying for no-shows. An attendee who books and never arrives, or arrives late, burns the prep time of everyone who did show up.

Put it on autopilot

You don't need to run the math by hand every time. Build the loaded hourly rate once for your common roles, drop the formula into a shared spreadsheet, and surface the cost on the calendar invite itself. Teams that simply display the running cost of a meeting in real time tend to start finishing early. The goal isn't to make people anxious about every minute; it's to make the trade-off visible, so the meetings that survive are the ones genuinely worth their price.
