Every meeting has an exchange rate: attendee-hours in, decisions out. Most organizations never compute it, which is how a weekly status meeting quietly consumes a mid-size salary every year. This calculator computes it.
The economics are direct — attendees × duration × loaded hourly cost — but the verdict logic is what matters: meetings genuinely earn their cost when they require real-time interaction (negotiation, decisions with dissent, creative collision, sensitive delivery). Status broadcasts, information relays and FYI-with-slides sessions are asynchronous content wearing a calendar invite.
Enter the meeting’s parameters and what actually happened in it. You get the true cost, an Email Probability score, the annualized cost if it recurs, and the async prescription — because “this could have been an email” deserves math, not just a mug slogan.
The formula
N, t, w_loaded- Attendees, duration, and loaded hourly cost (salary × ~1.4 overhead)
B_broadcast- Broadcast share — fraction of the meeting that was one-way information transfer
D_decisions- Decisions actually made that required the group present
I_interaction- Genuine back-and-forth density — questions, dissent, negotiation
S_sensitive- Sensitivity — content that ethically requires synchronous human delivery
How it works, step by step
- Count attendees and the meeting length; estimate the average salary of the room.
- Rate how much of the meeting was one-way broadcast versus genuine exchange.
- Count decisions that were actually made in the room and required the room.
- Mark whether it recurs — recurring meetings are where the real money hides.
- Read the true cost, the Email Probability verdict, and the async alternative.
Worked examples
The Monday all-hands status sync
14 people, 60 minutes, $85k average salary, 85% broadcast, 0 decisions, 6 laptops open, weekly. Email Probability: 95 — Certified email, costing $801 per week and ~$41,650 per year. Cost per decision: undefined, since none occurred. Prescription: written update + optional Q&A.
The quarterly pricing decision
5 people, 90 minutes, $120k average, 20% broadcast, 4 real decisions, interaction 9/10, one-off. Email Probability: 1 — Legitimately a meeting. $606 total, $151 per decision — cheap for choices that move revenue. The calculator endorses the calendar invite.
How to read your score
Frequently asked questions
How do you calculate the true cost of a meeting?
Attendees × duration × loaded hourly rate. The loading factor (~1.4× salary) covers benefits and overhead — the standard way HR computes what an employee-hour actually costs. An 8-person hour at $80k average salaries ≈ $430, before counting context-switching losses.
What genuinely requires a meeting instead of an email?
Four things reliably: decisions with live dissent to resolve, negotiation, creative collision (real-time riffing), and sensitive human delivery. Information transfer — the majority of most meetings — is what documents were invented for.
Why do recurring meetings cost so much more than they feel?
Because the cost is invisible and compounding: a weekly hour with 10 people at average salaries burns $30–60k per year — a hire’s worth of attention — while feeling like “just an hour.” The annualized output exists to make that visible.
What is a pre-read and does it work?
A short written brief sent before the meeting so room time starts at the discussion, not the download. Where genuinely adopted it reliably halves meeting length; its famous failure mode (nobody reads it) is solved by starting the meeting with 5 minutes of silent reading.
Are daily standups email in disguise?
Only if they are status broadcasts. A 10-minute standup that surfaces blockers needing live coordination earns its cost; a 25-minute one where each person recites yesterday is this calculator’s highest-scoring genre.
Is my meeting data stored?
No — like all Quirkulator tools, everything computes locally in your browser. Your org chart is safe.
Reference: what meetings really cost
| Attendees | Avg salary $60k | Avg salary $90k | Avg salary $130k |
|---|---|---|---|
| 4 people × 1h | $162 | $242 | $350 |
| 8 people × 1h | $323 | $485 | $700 |
| 12 people × 1h | $485 | $727 | $1,050 |
| 8 people × 30min, daily (yearly) | $40,400 | $60,600 | $87,500 |
| 12 people × 1h, weekly (yearly) | $25,200 | $37,800 | $54,600 |
Loaded cost = salary × 1.4 (benefits + overhead) ÷ 2,080 working hours. Context-switching losses not included — add ~15–25 minutes of degraded focus per attendee per meeting.
| Work type | Best format | Why |
|---|---|---|
| Status updates | Written doc / thread | One-way transfer; reading is 3–5× faster than listening |
| Decision with dissent | Meeting | Real-time negotiation resolves loops async cannot |
| Brainstorming | Hybrid | Async idea collection first, live collision second |
| Sensitive / personal news | Meeting (small) | Ethics require synchronous human delivery |
| FYI announcements | Written + optional Q&A | Broadcast content; questions are the only live part |
| Complex problem-solving | Meeting (≤5 people) | Working memory sharing degrades beyond ~5 |
