What are man-hours?
Man-hours (also called labor-hours) represent the total amount of work performed by one person in one hour, used to estimate labor needs and costs for a project.
The formula
Man-Hours = Number of Workers × Hours Worked per Worker. Multiplying man-hours by an hourly labor rate gives an estimated total labor cost for the job.
This calculator is for general project-planning and staffing estimates.
