How to Calculate Man Hours
Man hours, also called HH or labor hours, measure the total amount of work performed by people during a task, activity, shift or project. This metric is commonly used in operations, construction, maintenance, workforce planning and project control.
Man hours formula
For example, if 4 workers work 8 hours each, the total man hours are 32 HH.
Example calculation
| Workers | Hours worked | Total man hours |
|---|---|---|
| 4 | 8 | 32 HH |
| 10 | 12 | 120 HH |
| 25 | 7.5 | 187.5 HH |
How to calculate labor cost from man hours
If a team works 120 man hours and the hourly rate is $25, the labor cost is $3,000.
Why man hours matter
Man hours help estimate labor effort, compare productivity, measure project progress, calculate labor cost and understand how workforce time is being used.
Turn HH data into a dashboard
Instead of reviewing long Excel tables manually, you can upload workforce data and automatically generate KPI cards, charts and exportable reports.
