How this instrument works
A calendar invite shows a meeting's start time, end time, and attendee list — never its cost. But every attendee's time has a real dollar value to the organization paying them, and a meeting is, among other things, that many people's paid time being spent simultaneously in one room or one call rather than on anything else. This calculator makes that cost visible by multiplying the number of attendees by their average hourly rate and by the meeting's length in hours.
'Average hourly rate' here is meant as a fully-loaded figure — not just base salary divided by hours worked, but salary plus benefits, payroll taxes, and other employment overhead, which is typically noticeably higher than take-home pay alone would suggest. Using a bare salary-only rate will understate the true cost this calculator is trying to surface.
This is a direct time-cost multiplication only. It doesn't account for the broader cost of a meeting interrupting focused work, the context-switching cost of returning to a task afterward, or any value the meeting itself produced — a well-run meeting that avoids a costly mistake can easily be worth far more than its calculated cost, while a poorly run one can cost more than this number suggests once lost focus is factored in. Treat the figure as a visible floor on cost, not the full picture.
- Enter Number of attendees — everyone actually present for the meeting.
- Enter Average hourly rate ($) — a fully-loaded rate (salary plus benefits and overhead), not just base pay, averaged across attendees if their rates differ.
- Enter Meeting duration (hours) — how long the meeting runs, in hours (use a fraction like 0.5 for 30 minutes).
- Read Meeting cost ($) for the total dollar cost of everyone's combined time.
- Recalculate with a shorter duration or fewer attendees to see how much a leaner meeting would actually save.
Worked example — a 6-person, 1-hour status meeting
Six people join a routine 1-hour status meeting, at an average fully-loaded hourly rate of $45 across the group. Entering 6, 45, and 1 into the three fields gives Meeting cost ($) = 6 x 45 x 1 = $270.
That $270 is the direct cost of that single hour, every week it recurs — a weekly version of the same meeting costs roughly $14,000 a year in combined attendee time alone, a figure that rarely gets weighed against the meeting's actual weekly value when the invite goes out on autopilot.
Questions
What hourly rate should I actually use?
A fully-loaded rate — base salary plus benefits, payroll taxes, and other employment overhead — rather than take-home pay alone, since that fully-loaded figure is closer to what the meeting genuinely costs the organization. If attendees have different rates, use a reasonable average across the group; the result will be an approximation either way, but a fully-loaded average is a meaningfully better approximation than base salary alone.
Does this include the cost of lost focus or context-switching, not just the meeting time itself?
No — this calculator multiplies attendee count, rate, and duration only, giving a direct floor on the meeting's cost. Many people also lose additional working time before and after a meeting reorienting to whatever task it interrupted, which isn't captured here; the true cost of a meeting-heavy schedule is often higher than this number alone suggests.
Why does making meeting cost visible matter?
Because meeting cost is normally invisible — it never appears on the calendar invite, the meeting agenda, or any budget line item the way a purchase order would. Seeing an explicit dollar figure attached to a recurring meeting tends to prompt useful questions that wouldn't otherwise get asked: does this need to be an hour, does it need everyone currently invited, and does it need to happen every week?
How do I estimate an average hourly rate if I only know annual salaries?
A common rough conversion divides annual salary by roughly 2,080 (the standard 40-hour, 52-week work year) to get a base hourly figure, then adds an estimate for benefits and overhead — commonly cited as adding somewhere in the range of 25 to 40 percent on top of base pay, though this varies meaningfully by employer and role, so treat any such multiplier as a rough approximation rather than a precise figure.
Can this calculator handle meetings shorter than an hour?
Yes — enter the duration as a fraction of an hour, such as 0.5 for a 30-minute meeting or 0.25 for a 15-minute standup. The formula scales linearly with duration, so a half-hour version of a given meeting simply costs half as much as the full-hour version at the same attendee count and rate.
