Meeting Cost Calculator

How to Use the Meeting Cost Calculator

1. Enter the number of attendees. Count everyone who will actually be on the call, including optional invitees who usually join.
2. Type in the average hourly rate. For a quick estimate, use the loaded cost (base salary plus benefits plus overhead), which typically runs 1.3 to 1.5 times the base hourly wage.
3. Set the planned duration in minutes. The breakdown panel recomputes instantly - total cost, cost per minute, cost per hour, and cost per person.
4. Optionally start the live timer when the meeting actually begins. The running cost ticks up in real time so everyone on the call can see the money burning.
5. Share the screen during the meeting. A visible counter is the single most effective argument for ending meetings early.

What This Tool Does and How It Works

The calculator is a pure arithmetic tool with one central formula: total cost equals attendees multiplied by hourly rate multiplied by duration in hours. From that total, per-minute cost is total divided by minutes, per-person is total divided by attendees, and the live timer accumulates the per-second fraction (rate times attendees divided by 3600) on each tick. The implementation holds all four inputs in Preact component state and recomputes on every change, so the numbers update without a submit button. The live timer uses a setInterval at 1 Hz against an anchor timestamp captured on start, so pausing or backgrounding the tab does not lose time - on refocus the running cost snaps to the correct figure.

No currency library is used; the page renders numbers with toFixed(2) and a fixed dollar symbol as convention. If you enter a rate in another currency (euros, pounds, rupees), the math is identical - the symbol is cosmetic. There is no tax, no rounding mode for regulatory currencies like CHF 0.05 stepping, and no cost-center allocation; this is a back-of-envelope calculator aimed at real-time awareness, not payroll accounting.

When You Would Use the Meeting Cost Calculator

• Before sending a calendar invite, to sanity-check that the meeting is worth its cost ("is 45 minutes with eight senior engineers really the best way to resolve this?").
• At the start of a recurring weekly status meeting, shown on shared screen so the team weighs whether each agenda item earns its slice.
• In budget conversations with leadership, to quantify what a proposed "all-hands touch-base" actually costs the company over a quarter.
• During engineering-manager coaching, teaching new leads to think about interruption cost - three engineers pulled into a 30-minute sync is real money.
• When pitching a meeting cull or "no-meeting Wednesday" policy to leadership, to put a dollar number on the recovered focus hours.
• In vendor or agency contracts where you are billed by time and want a live awareness of how expensive each hour on a call really is.

Common Pitfalls and Edge Cases

The headline pitfall is using base salary instead of fully loaded cost. A $120,000 salary looks like roughly $60 per hour, but the fully loaded cost (benefits, payroll taxes, equipment, office, PTO coverage) is closer to $90 per hour. Using the lower figure understates meeting cost by about a third. A second pitfall is forgetting that cost is not the same as value: a 30-minute meeting that prevents a bad architectural decision can be worth many multiples of its dollar cost, and a cheap meeting that everyone zones out in is still wasted. Use the number as a floor for "what did this cost us at minimum", not as a verdict. Other edge cases: part-time or contractor attendees may have wildly different rates than a company-average blended rate, and for non-US contexts the 1.3-1.5x loaded multiplier varies (European countries with higher employer social contributions push closer to 1.6-1.8x). When you are mixing senior and junior staff, a single average understates the cost of senior time.

The Economics of Meetings

Formal research on meeting cost is thin but consistent: Harvard Business Review and MIT Sloan surveys over the past decade find executives spending 23-30 hours weekly in meetings, with participants self-reporting 30-50% as unproductive. Context-switching research going back to Gloria Mark\'s 2005 UC Irvine studies shows roughly 23 minutes to regain full focus after an interruption - so a 30-minute meeting in mid-morning actually costs closer to 53 minutes of productive work. Parkinson\'s Law ("work expands to fill the time available") is often invoked for meetings and matches observed behavior, though the "Law" itself is a 1955 satirical observation, not a controlled study. The honest summary: time and focus are scarce, meetings aggregate both, and a visible price tag changes behavior.

Comparison to Alternatives

Dedicated meeting-cost Chrome extensions (MeetingCalc, Meeting Cost Clock) do the same math with plumbing to read calendar invites directly - better if you want the estimate baked into Google Calendar. Enterprise analytics tools (Microsoft Viva Insights, Time is Ltd., Worklytics) compute cost across an organization from calendar metadata - useful for HR-level intervention but useless in the moment. A spreadsheet does the same job and can be customized for your multipliers. This calculator wins on speed and low friction: open a tab, punch in numbers, screen-share. It loses whenever you want calendar integration, team-wide reporting, or historical tracking.
