What a Meeting Actually Costs, Minute by Minute

Put eight people in a room for 45 minutes and something invisible changes hands: roughly 58 hours of paid capacity, at whatever your loaded rates are. The Meeting Cost Calculator prices that exchange — and its outputs are designed to be quoted in arguments about calendars.

The per-attendee arithmetic

The core formula is small enough to audit by hand:

cost = hourly rate × (minutes ÷ 60) × headcount × overhead multiplier

The simplest case: three colleagues at $50/hour in a one-hour meeting cost 50 × 1 × 3 = $150. The tool also divides that total into two reference figures — $2.50 per minute and $50 per attendee — which turn out to be the numbers people actually remember. The per-minute figure is the honest one: it doesn't flatter a meeting by averaging over its length, and it makes the overrun math visceral (fifteen minutes past the hour is $37.50, not "just a few more minutes").

Salaries, converted at 2080 hours

Most attendees don't know their hourly rate; they know their salary. The tool converts any annual salary to an hourly rate by dividing by the annual hours you set — 2080 by default, the standard 40-hour year without vacation adjustment. A $104,000 salary is therefore $50 per hour, and an hour of that person's meeting time costs $50 before overhead. The conversion factor is adjustable because the honest divisor varies: 2080 for pure payroll math, closer to 1800–1900 if you want the rate to reflect actual working weeks. Higher divisor, lower hourly rate, cheaper-looking meeting — worth remembering when the estimate will be quoted.

The overhead multiplier: loaded labor

An employee's real cost is not their salary. Benefits, payroll taxes, equipment and workspace typically add 20–40% on top, which is what the overhead multiplier models. Set it to 1.3 and every rate in the calculation is treated as a loaded cost. Watch the effect on a real configuration — eight attendees at $45/hour, meeting 45 minutes, overhead 1.3:

45 × 0.75 × 8 × 1.3 = $351 total
$7.80 per minute · $43.88 per attendee

The same meeting without overhead would report $270. Neither number is "right" — unloaded cost answers "what leaves the bank account this month," loaded cost answers "what did the organization actually spend." For comparing a meeting against its output, use loaded; it's the version your CFO would compute.

Itemized attendees: when rates differ

Uniform rates are the quick path, but real meetings mix populations — two engineers, a designer, and a director do not cost the same per hour. The itemized mode takes each attendee (or group) with its own hourly rate or annual salary and its own headcount, then sums the rows. The per-attendee breakdown this produces is the most persuasive artifact the tool generates, because it shows the meeting's cost is not shared equally — the most expensive person's presence often exceeds everyone else's combined, which reframes whether they need to be in the room at all.

Recurring meetings compound quietly

One $351 meeting is an anecdote; a weekly one is a budget line. Multiply by 52 and that configuration spends $18,252 a year — a full junior salary burned in a conference room. The annualization is where the tool's quick numbers start to bite, and it's also where the deeper questions live: what the invoice math looks like when you bill clients for meeting time, and how utilization-based rates change the answer. Those are covered in invoices and the real cost of meetings; this tool gives you the raw per-meeting figure that all of it builds on.

Try it yourself

The Meeting Cost Calculator takes headcount, rates or salaries, duration and overhead, and returns total, per-minute and per-attendee costs — all computed locally, no salary data leaves your browser. When the attendees span time zones, the Time Zone Meeting Planner finds the slot that costs the least goodwill. And if the meeting exists to produce client work, the Invoice Generator is where that time eventually gets billed.
