The meeting cost calculator above converts attendees, hourly rates and duration into a single dollar figure, then extends it to what the same meeting costs across a year if it recurs. It also folds in preparation and follow-up time, which is usually invisible on the calendar and often exceeds the meeting itself, and applies an overhead multiplier so the answer reflects the employer's real cost rather than gross wages alone.
Arb Digital runs this calculation before recommending any change to a client's reporting or approval process, because "we have a weekly status call" and "we spend forty thousand dollars a year on a weekly status call" are the same fact stated two ways, and only one of them prompts a decision. This page shows how the number is built so you can defend it in a room.
What This Meeting Cost Calculator Does
It answers four questions. What does this specific meeting cost in staff time? What does each minute of it cost, so you can price an overrun? What does it cost annualised if it repeats? And how many person-hours does it consume per year — the figure that matters when the constraint is capacity rather than cash.
The fourth grid figure is deliberately provocative: what you would save by cutting fifteen minutes off every occurrence. It is the cheapest change available to most recurring meetings, and seeing its annual value tends to settle the argument about whether a sixty-minute default is worth keeping.
Every input is visible and adjustable. Nothing is assumed on your behalf beyond the defaults, and the overhead multiplier can be set to 1.0 if you want gross wages only.
How to Use It
- Enter the number of attendees. Count everyone who joins, including people who are only there to listen — their time costs the same as anyone else's.
- Enter an average hourly rate. For salaried staff, divide the annual salary by 2,080, the number of hours in a standard 52-week, 40-hour year.
- Enter the scheduled duration, plus a realistic estimate of prep and follow-up time per person. Ten minutes is conservative for anything with an agenda or notes.
- Set the overhead multiplier. 1.3 is a common working figure for the cost above gross wages; use your own if finance has given you one.
- Choose the recurrence and how many weeks a year it does not happen, then press Calculate to see the per-meeting and annualised figures together.
The Formula: How Meeting Cost Is Calculated
The base calculation is straightforward: cost = attendees × hourly rate × hours × overhead multiplier. Eight people at $75 an hour for one hour is $600 in gross wage time. Applying a 1.3 overhead multiplier gives $780. Prep and follow-up are added as extra time per person: ten minutes each across eight people is 80 minutes, or 1.33 hours, adding a further $130 at the loaded rate and bringing the total to $910.
Annualising multiplies by the number of occurrences. A weekly meeting held 48 times a year — 52 weeks less four for holidays — costs 48 × $910 = $43,680. That is the number worth writing down. It is comparable to a salary, and it is being spent on a recurring calendar entry that in most organisations has never been formally reviewed.
Person-hours are calculated the same way without the money: 8 attendees × (1 hour + 10 minutes each) × 48 occurrences works out at roughly 448 person-hours a year, which is over a quarter of one full-time person's annual capacity.
Why the Overhead Multiplier Matters
An employee's hourly wage is not what an hour of their time costs the business. Payroll taxes, insurance, paid leave, retirement contributions, equipment and workspace all sit on top. In the United States, the Bureau of Labor Statistics Employer Costs for Employee Compensation series tracks the split between wages and benefits directly, and it publishes the current proportions each quarter — worth checking rather than guessing if you need a defensible figure.
Using gross wages alone systematically understates meeting cost, often by a quarter or more. Using a billable rate instead systematically overstates it, because a billable rate includes profit margin that is not a cost at all. The multiplier approach sits between the two and is the one most finance teams will accept. If you need the full loaded cost of a role rather than an estimate, our employee cost calculator builds it up component by component.
The Hidden Cost Nobody Counts: Prep, Follow-Up and Fragmentation
A sixty-minute meeting rarely occupies sixty minutes of anyone's day. There is reading beforehand, notes afterwards, and the actions that get logged in whatever system the team uses. Including a modest per-person allowance for that is the difference between a plausible number and one that undersells the true figure by twenty per cent.
Fragmentation is harder to quantify and deliberately left out of this calculator, because putting a number on it would require assumptions we cannot support. The observation itself is uncontroversial though: a meeting placed in the middle of an afternoon leaves two shorter blocks rather than one long one, and some kinds of work do not fit into the fragments. If you want to model that, the honest way is to compare the calendar-hours cost calculated here against the deep-work hours actually available, using the work hours calculator for the denominator.
Reading the Number Without Overreaching
This figure is a cost, not a verdict. Plenty of expensive meetings are worth every dollar — a decision that unblocks a project, a negotiation, an onboarding session for a new team. The calculator does not know what the meeting produced, and no calculator can. What it does is make the cost side visible so it can be weighed against the benefit side, which is usually the only half anyone discusses.
The most useful comparison is against an alternative, not against zero. A weekly hour-long status call costing $43,680 a year should be compared with the cost of the written update that would replace it — which is not free either, and takes real time to produce. If the written version takes each person fifteen minutes and half as many people need to read it, run both through the calculator and compare. That is a decision with evidence behind it.
For agencies and consultancies, the same arithmetic applies to internal meetings but with a sharper edge: every internal hour is an hour not billed. Our billable hours calculator shows the utilisation side of that, and the project profitability calculator shows what happens to margin when internal time creeps up on a fixed-fee engagement.
Attendee Count Is the Biggest Lever
Cost scales linearly with headcount, and headcount is usually the input with the most slack in it. Reducing a twelve-person meeting to seven cuts cost by more than forty per cent, which is a larger saving than any realistic reduction in duration. It is also the change with the most resistance, because attendance is often about visibility rather than contribution.
A practical test: for each attendee, would the meeting reach a different outcome without them? If the honest answer is no, and they only need to know what was decided, the notes serve them better than the hour did. The calculator makes this arithmetic concrete — change the attendee number and watch the annualised figure move.
Duration is the second lever and the easier one. Meetings expand to fill the slot booked, so a default of 60 minutes produces 60-minute meetings and a default of 45 produces 45-minute ones, with the same agenda covered. The "saving if 15 minutes shorter" figure in the results grid prices that change directly.
Where the Estimate Is Weakest
Averaging hourly rates across attendees hides the fact that seniority is unevenly distributed. A meeting with three executives and five junior staff has a very different cost from eight people at the average, even though both give the same total. If the spread is wide, run the calculation twice — once for the senior group, once for the rest — and add the results rather than averaging.
The second weakness is the assumption that staff time saved becomes productive time. Cancelling a meeting does not automatically convert that hour into output. The saving is an opportunity, not a realised gain, and describing it as money returned to the business overstates the case. Rates themselves vary widely by role and region; the BLS Occupational Employment and Wage Statistics programme publishes the official distributions if you need something more precise than a departmental average.

- Using gross wages with no overhead multiplier — payroll taxes, benefits and workspace are real costs, and ignoring them understates the total by a quarter or more.
- Using a billable rate as the cost — a billable rate contains profit margin, so it overstates cost as badly as gross wages understate it.
- Counting only the scheduled slot — prep and follow-up are real time, and leaving them out makes every meeting look cheaper than it is.
- Averaging rates across a very mixed group — an average hides the executive time in the room, which is where most of the cost usually sits.
- Treating the annualised figure as cash saved — it is capacity released, and capacity only becomes value if it is redirected to something useful.

Frequently Asked Questions
Multiply the number of attendees by their average hourly rate and by the duration in hours, then apply an overhead multiplier for payroll taxes and benefits. Eight people at $75 an hour for one hour with a 1.3 multiplier costs $780 before prep time is added.
Divide the annual salary by 2,080, which is the number of hours in a 52-week year at 40 hours a week. A $156,000 salary works out at $75 an hour before any overhead multiplier is applied.
1.25 to 1.4 is a common working range for payroll taxes, benefits, paid leave and workspace. If your finance team publishes a loaded cost per employee, use that instead — it will be more accurate than any general figure.
Yes, if you want a number that reflects reality. Reading the agenda, writing notes and logging actions all take real time, and leaving them out typically understates the total by fifteen to twenty per cent.
Multiply the per-meeting cost by the number of times it actually happens in a year, not the theoretical maximum. A weekly meeting realistically runs around 48 times once holidays and cancellations are accounted for.
Not directly. It releases capacity rather than returning cash, and the value is only realised if the time is redirected to work that produces something. Presenting it as money saved overstates what actually changes.
Cutting attendees usually moves the number more, because cost scales linearly with headcount and the attendee list typically has more slack in it than the agenda does. Cutting duration is easier to agree and still worth doing.
Figures produced by this tool are planning estimates only — actual costs depend on your organisation's real compensation structure, overhead allocation, and how meeting time is accounted for.
