meeting cost

temmet is a free browser-based cost meter — no accounts, no data sent anywhere. This is the use case it was originally built for: showing what a meeting is costing in real time, so the room can see it.

for who

Engineering leads, managers, anyone who runs or attends meetings and has noticed that "this could have been an email" rarely lands without numbers behind it.

the job

Track the live cost of a meeting so the room can see it on a screen-share. After the meeting, save the session so you can compare across weeks ("our standups cost $X/sprint, our planning meetings cost $Y").

how to map it

1. Open temmet and switch to Advanced mode.
2. Add one row per attendee. The role field becomes the job title; the rate is the hourly cost.
3. Set a session name like "Q3 planning" or "weekly engineering sync".
4. Press TIME = MONEY. Share your screen if you want the room to see the running total climb.
5. Press esc at the end. The session lands in history.

If you run the same meeting often (a daily standup, a weekly sync), save the setup as a template so future runs are one click.

the remix

Two non-obvious moves once you've been doing this a while:

• Set the default session name to a question. "What are we deciding?" or "What problem are we solving?" — the field is pre-filled before every new session, which forces every meeting to start with intent.
• Use the search box in history to compute spend per topic. Tag your meetings with consistent labels ("planning", "review", "1:1") and you can filter the export to that label and see the total — temmet doesn't compute it for you, but a one-cell SUM in any spreadsheet does the rest.

tips

• For a quick check without per-person detail, use Simple mode. Pick a count and an average rate, and you've set up a session in five seconds.
• The summary screen shows cost per participant. That's the number that surprises people more than the total.
• If someone steps out for ten minutes, you don't have to remove them — but you can pause the meter if everyone is taking a real break.
• Export PDF for any meeting where you want a paper trail. The output is A4-ready.
