The Real Cost of Meetings That Start Late

Minutes spent waiting for a meeting to begin add up across attendees and weeks. How to price a late start, what research links it to, and how to start on time.

Nine people are on the call at 10:00. The person who called the meeting is not. At 10:04 someone says, "Should we wait?" At 10:07 the organizer joins, apologizes, and spends two minutes catching up the one person who joined after them. The meeting that was booked for thirty minutes now has twenty-one minutes left, and nine people have already spent seven minutes each doing nothing in particular.

Late starts feel trivial. A few minutes here and there. Run the numbers, and they stop looking trivial very quickly, partly because of the arithmetic and partly because of what researchers have found about how lateness changes the meeting that follows.

The arithmetic of waiting

The basic meeting cost formula is simple: number of attendees, times the average loaded hourly cost of each attendee, times the length of the meeting in hours. The same formula works for the minutes spent waiting.

To get an hourly figure from an annual salary, a common approach divides by 2,087 hours, the divisor the U.S. Office of Personnel Management uses to convert federal annual pay into an hourly rate. Salary alone understates the cost of an employee's time, because benefits, payroll taxes and overhead add to it. Many finance teams use a loaded rate that is noticeably higher than base pay. Your own finance team can tell you which multiplier your organization uses.

Take an illustrative example. Nine attendees, an average loaded cost of $75 an hour, and a seven-minute late start. Seven minutes is about 0.117 of an hour. Nine people times $75 times 0.117 is about $79 of paid time spent waiting, for one meeting.

Now repeat it. If that team has a recurring meeting three times a week that starts five to seven minutes late, the waiting adds up to roughly $200 or more a week. Over a 48-week working year, that is close to $10,000 of salaried time spent waiting for a meeting to begin. These figures are an illustration of how the formula behaves, not a measurement of any particular company, but the shape holds: small, frequent delays multiplied by many people become large.

What lateness does to the meeting itself

The direct cost of waiting is only part of the picture. Researchers have also looked at what happens after a late start.

Joseph Allen, Nale Lehmann-Willenbrock and Steven Rogelberg studied meeting lateness in a paper published in the Journal of Organizational Behavior in 2018. They analyzed recorded meetings and found that meetings that started late were associated with worse outcomes than meetings that started on time, including fewer ideas generated and less effective problem solving, and with more negative interaction among attendees. The study is about associations in the meetings they observed, so it does not prove that lateness alone caused the difference. It does match what most people feel in the room: a meeting that starts with irritation tends to stay a little irritated.

Rogelberg, whose book The Surprising Science of Meetings collects much of this research, has also written about how lateness signals disrespect for others' time, and how that signal can carry into how people behave during the meeting.

Why meetings start late

Late starts usually have ordinary causes.

• - Back-to-back scheduling. Calendars that place one meeting at 10:00 and the next at 10:30 leave no time to walk, take a break or switch context. If the first runs over by even a minute, the second starts late.
• - Waiting for the important person. Teams often wait for the most senior attendee, which teaches everyone that the start time is a suggestion.
• - Technology. Video links, screen sharing and room equipment can eat the first few minutes.
• - Recaps for latecomers. Each time the meeting stops to catch up someone who joined late, everyone who arrived on time pays for it again.

How to start on time, every time

Start at the scheduled minute, whoever is missing. This is the single most effective habit. When people learn the meeting starts on time, they arrive on time. The organizer has to model it.

Do not recap for latecomers. Point them to the notes or the chat. If the meeting needs a recap, do it once at the end, or not at all.

Make meetings shorter by default. Some calendar tools let you set default meeting lengths of 25 or 50 minutes instead of 30 or 60. That builds in a few minutes between meetings, which makes on-time starts more realistic.

Put the most important item first. If the first few minutes are critical, people are less likely to drift in late. If the first item is small talk, they will skip it.

Prepare the technology before the start time. Join the call or test the room a minute or two early, with any slides already open.

Track it. If late starts are a chronic problem, keep a simple tally for a few weeks: scheduled start, actual start, number of attendees. Multiply it out using the meeting cost formula and share the total. A number on a slide often changes behavior faster than a reminder in chat.

When waiting is the right call

There are exceptions. If the meeting exists to make a decision that only one person can make, starting without them may waste more time than waiting. If the person presenting is delayed, the meeting may not be able to begin. In those cases, the better move is to decide quickly: wait a set number of minutes, then reschedule. Two minutes of waiting is a courtesy. Fifteen minutes of waiting is a canceled meeting that nobody canceled.

If the meeting cannot happen without someone, consider whether it should be shorter, smaller or replaced with a written update that the key person can answer on their own time.

A small rule with a large return

Starting on time costs nothing. It does not need new software, a training program or a policy memo. It needs one person, usually the organizer, to begin at the minute on the invitation, every time, and to stop rewarding late arrivals with a recap.

Back on that 10:00 call, the organizer could have joined at 9:59 and opened with the first agenda item at 10:00 sharp. The nine people would have had their full thirty minutes, the meeting would likely have ended on time, and the next meeting on everyone's calendar would have started on time too. That is how a few minutes become a culture.
