Meeting Cost Estimator

Costing a meeting is an exercise in fully loaded labour rates. Base salary understates what an employer actually pays per hour, so the calculation multiplies the hourly wage by an overhead factor before multiplying by duration and headcount. That factor is not arbitrary: the US Bureau of Labor Statistics series on employer costs for employee compensation consistently finds that wages and salaries make up roughly 69 percent of total compensation for civilian workers, with benefits accounting for the remaining 31 percent, which corresponds to a multiplier near 1.45. Its components are employer payroll taxes at 7.65 percent for Social Security and Medicare plus unemployment insurance, health premiums, retirement contributions, paid leave, and workers compensation. Contractors without benefits sit closer to 1.1, while senior staff with premium packages and allocated facilities can exceed 1.6. Annualising uses 2,080 scheduled hours per full-time year, 40 hours across 52 weeks, which is what makes the full-time-equivalent comparison meaningful: a recurring meeting consuming 2,080 person-hours a year has absorbed one entire salaried position. Two limitations should be stated plainly. First, this is a direct cost figure, not a waste figure. A short meeting that prevents a wrong decision can be worth many multiples of its labour cost, and the calculation says nothing about the value produced. Second, it understates disruption. A one-hour meeting dropped into the middle of a morning does not remove one hour of capacity but fragments the block around it, and for work requiring sustained concentration the usable loss is larger than the calendar entry. Averaging attendee salary also hides distribution, since a handful of senior participants often account for most of the total while appearing as ordinary headcount.

Charging time to an activity is an accounting technique older than the meetings it is now applied to. Cost accounting in the early twentieth century, including Alexander Hamilton Church's work on machine-hour and burden rates, established the practice of loading indirect expenses onto productive hours rather than treating them as a lump of unallocated overhead, and Frederick Winslow Taylor's time studies made hours the unit that labour cost attached to. The specific idea of tracing overhead to the activities that consume it was sharpened much later by Robert Kaplan and Robin Cooper at Harvard Business School in the late 1980s under the name activity-based costing, which is the direct intellectual ancestor of treating a meeting as an activity with a price. The raw compensation data that makes the overhead multiplier credible comes from the Bureau of Labor Statistics, whose National Compensation Survey and the Employer Costs for Employee Compensation series have published the wage-to-benefit split on a regular schedule for decades. Meetings themselves became a serious research subject in the 1990s and 2000s, with organisational psychologists including Steven Rogelberg at the University of North Carolina at Charlotte building an empirical literature on meeting load, attendee satisfaction, and design. The costing argument reached general management readers through Leslie Perlow, Constance Noonan Hadley, and Eunice Eun in their 2017 Harvard Business Review article Stop the Meeting Madness, which drew on Bain and Company analysis showing that a single recurring weekly executive meeting at one large firm ultimately consumed on the order of 300,000 hours a year once all the downstream preparation meetings were counted. That style of arithmetic is what meeting cost calculators reproduce.
