Meeting Cost & Time Waste
Calculate the true dollar cost of a meeting from attendee count, salaries, and duration.
Formula
Meeting Cost = (Duration × Attendees × Hourly Rate) + Prep Costs; Waste = Cost × (100 - Productivity%)
Worked Examples
Example 1: Executive Strategy Meeting
Problem:8 executives, 2-hour meeting, $150/hr avg cost, 30 min prep each, 60% productive. Weekly occurrence.
Solution:Meeting time cost:\n2 hours × 8 people × $150 = $2,400\n\nPrep time cost:\n0.5 hours × 8 people × $150 = $600\n\nTotal per meeting: $3,000\n\nProductivity breakdown:\n60% productive = $1,800 value\n40% unproductive = $1,200 waste\n\nWeekly: $3,000 × 1 = $3,000\nAnnual: $3,000 × 52 = $156,000\nAnnual waste: $62,400\n\nCost per minute: $3,000 / 120 = $25/minute\n\nEvery minute over time costs $25.\n5-minute late start × 52 weeks = $6,500/year.
Result:$3,000/meeting | $62K annual waste | $25/minute
Example 2: Daily Standup (Team of 10)
Problem:10 developers, 15-min standup, $85/hr avg, no prep, 80% productive. Daily (5×/week).
Solution:Meeting cost:\n0.25 hours × 10 people × $85 = $212.50\n\nProductivity:\n80% productive = $170 value\n20% unproductive = $42.50 waste\n\nWeekly (5 meetings): $1,062.50\nAnnual: $55,250\n\nThis is actually efficient:\n- Short duration\n- High productivity\n- Necessary coordination\n\nBUT if standups routinely go 30+ minutes:\n$425/day × 260 = $110,500/year\n\nDouble the cost for double the time.
Result:$212/meeting | $42 waste | Efficient if kept short
Example 3: All-Hands Meeting
Problem:50 employees, 1-hour monthly, $60/hr avg, 15 min prep, 40% productive.
Solution:Meeting cost:\n1 hour × 50 people × $60 = $3,000\n\nPrep cost:\n0.25 hours × 50 × $60 = $750\n\nTotal: $3,750\n\nProductivity:\n40% productive = $1,500 value\n60% unproductive = $2,250 waste\n\nAnnual (12 meetings): $45,000\nAnnual waste: $27,000\n\nConsider:\n- Record for async viewing\n- Reduce to quarterly\n- Make more interactive\n\nAlternative: Video update + 15-min Q&A\n15 min × 50 × $60 = $750 (80% savings)
Result:$3,750/meeting | $27K annual waste | Consider async alternative
Frequently Asked Questions
How do I calculate meeting cost?
Meeting Cost = (Duration in hours × Number of attendees × Average hourly cost) + Prep time costs. Include fully-loaded costs (salary + benefits + overhead = ~1.3-1.5× salary). A 1-hour meeting with 6 people at $75/hr = $450 direct cost, not counting prep or opportunity cost.
What is the average cost of a meeting?
Studies suggest average professional meeting costs $300-500 per hour of meeting time. For senior executives, this easily exceeds $1,000/hour. Harvard Business Review found executives spend 23 hours/week in meetings, costing organizations millions annually.
Should every meeting have an agenda?
Yes. Meetings without agendas are 40% more likely to go over time and 60% less likely to achieve objectives. Agenda should include: purpose, time allocated per topic, expected outcomes, and required preparation.
How many people should attend a meeting?
Jeff Bezos' two-pizza rule: if you can't feed the team with two pizzas, too many people. Research shows: 4-6 attendees optimal for decisions, 2-3 for brainstorming quality. Each additional person beyond optimal reduces per-person contribution.
