What a Meeting That Runs 15 Minutes Over Actually Costs

Guides · Updated October 2026

The 30-minute standup that ends at 9:47. The "quick sync" that finds its second wind at the 55-minute mark. Everyone has lived this, and almost nobody has priced it. People ask what it costs when a meeting runs over like that. The answer is embarrassingly easy to compute, and once you see the number you will never sit through a drifting meeting the same way again.

Here is the formula. Take the average salary, divide by 2,080 working hours a year, divide by 60 for the per-minute rate, and multiply by headcount. That is your meeting's burn rate per minute. Every minute past the scheduled end multiplies straight through it.

Worked example 1: 8 people, $95,000 average salary, 15 minutes over

Step	Math	Result
Hourly rate	$95,000 ÷ 2,080	$45.67/hr
Per-minute rate	$45.67 ÷ 60	$0.76/min
Whole room per minute	$0.76 × 8	$6.09/min
15 minutes over	$6.09 × 15	$91.38

Ninety-one dollars. For one meeting running one quarter-hour long. Nobody approved that spend, nobody logged it, and it happened because two people wanted to "circle back" on something that could have been an email.

Worked example 2: 20 people, $120,000 average salary, 15 minutes over

Step	Math	Result
Per-minute rate	$120,000 ÷ 2,080 ÷ 60	$0.96/min
Whole room per minute	$0.96 × 20	$19.23/min
15 minutes over	$19.23 × 15	$288.46

The cost of a meeting running over, annualized

One-off overruns are rounding errors. Chronic overruns are a budget line. Take a weekly team meeting with 8 people at that $95,000 average. It runs 10 minutes over, every week, all year. That is $6.09 a minute times 10 minutes times 52 weeks: $3,167 a year. For one meeting. Most managers sit in four or five recurring meetings, and the overrun habit is rarely confined to one of them.

This is why I think overrun is worse than a bad meeting. A bad meeting is at least visible: people complain, someone eventually cancels it. Overrun is invisible. It never appears on an expense report, nobody's calendar shows it, and the people paying for it are the same people who sat there watching the clock. It is the only meeting cost with no decision attached to it.

Why overrun is the cheapest meeting cost to kill

Here is the good news. Of every dollar meetings cost, overrun is the easiest to eliminate, because the fix is free and the room is already assembled. Three things actually work:

End every meeting five minutes early on purpose. Schedule 25-minute and 50-minute meetings instead of 30 and 60. The buffer absorbs the drift, and people get their bio break. This one change probably eliminates half of all overrun in a typical company.

Name a closer. Not the organizer, who is busy running the thing. One person whose only job is to say "we have five minutes left" and then "we are at time, parking lot the rest." The parking lot is a real list, written down, reviewed at the start of the next meeting. Items that die in the parking lot were never worth the overrun.

Put the burn rate on the screen. A live cost ticker changes behavior faster than any policy memo. When the room can see $6 a minute ticking past the scheduled end, the "one more thing" people suddenly remember their email exists. That is exactly what our calculator's live timer is for.

Pick one recurring meeting this week. Shorten the invite by five minutes and assign a closer. It costs nothing, and it is the highest-return meeting intervention I know.

Frequently asked questions

How do you calculate the cost of a meeting running over?

Multiply the room's per-minute rate by the overrun minutes. Per-minute rate is (average salary ÷ 2,080 ÷ 60) × headcount. Eight people at $95,000 costs $6.09 per minute, so 15 minutes over is $91.38.

Should you include benefits and overhead in the salary number?

For a truer number, yes. A common rule is 1.25 to 1.4 times salary to cover benefits, payroll taxes, and overhead. That turns the $91 example into roughly $114 to $128. Use base salary for a conservative figure everyone will accept, loaded cost when you want the honest one.

What is the 25/50 rule for meetings?

Schedule 25-minute meetings instead of 30, and 50 instead of 60. The built-in buffer absorbs natural drift and gives people back-to-back breathing room. It is the simplest structural fix for chronic overrun.

Does overrun really cost money if everyone is salaried?

Yes, in opportunity cost. Those 15 minutes were already bought and paid for, and they were budgeted for the next task, the deep work block, or simply going home on time. Salaried time is not free time. It is the most expensive time a company buys.

How much does a 12-person meeting running 30 minutes over cost?

At a $95,000 average salary, the room burns $9.13 a minute, so 30 minutes over is about $274. At a $150,000 average, the same overrun is about $433.
