Calculate project man-hours, plan crew size or working duration, and estimate paid labor cost with an explicit productivity factor.

Defaults: 8 paid hours/day and 100% effective capacity. Adjust these for your project.

Labor effort and planning estimates. Paid cost uses gross hours; productivity changes effective capacity, not paid time.

Labor cost and weekly schedule

Blank omits cost. Zero means no paid labor cost.

Default: 5 workdays/week. Converts working days to schedule weeks.

Manhours Formula

The following formula is used to calculate the total manhours.

MH = W × H × D

Variables:

  • MH is the total manhours
  • W is the number of workers
  • H is the hours worked per day
  • D is the number of days

To calculate the total manhours, multiply the number of workers by the hours worked per day and then by the number of days.

What are Manhours?

Manhours represent the total amount of work performed by all workers in a specific period of time. It is a unit of measure that helps in planning and tracking the labor cost and efficiency of a project. Manhours are crucial for project management, budgeting, and scheduling, as they provide a clear picture of the labor input required for a task or project.

How to Calculate Total Manhours?

The following steps outline how to calculate the total manhours for a project.

  1. First, determine the number of workers (W) assigned to the project.
  2. Next, determine the hours worked per day (H) by each worker.
  3. Then, determine the number of days (D) the project will take.
  4. Use the formula from above: MH = W * H * D.
  5. Finally, calculate the total manhours (MH).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.
