Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Use loaded costs if desired. Equal preparation time for each attendee; travel and opportunity costs are not inferred.
Example Calculation
- Hourly costs per attendee: 30,40,50
- Meeting duration: 1 h
- Preparation per attendee: 0.25 h
Attendee costs 30,40,50 per hour for one meeting hour plus 15 minutes of preparation total 150.
Frequently asked questions
How do I use this calculator?
Enter hourly costs per attendee, meeting duration, preparation per attendee. The result updates automatically. Use Reset to restore the example values.
What method does it use?
labor cost=Σhourly attendee costs × (meeting+preparation).. Use loaded costs if desired. Equal preparation time for each attendee; travel and opportunity costs are not inferred.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
