Man-Hours Calculator
Calculate total project man-hours, full-time work week equivalents, and total labor costs.
What is the Man-Hours Calculator?
Man-hours calculation measures the total labor effort in uninterrupted working hours required to execute a specific project or construction task. It multiplies the total number of assigned workers by the total hours worked per day and total scheduled project working days. This equips project managers and contractors with accurate labor estimates to schedule project milestones, allocate personnel, and submit competitive project bids.
The Man-Hours Calculator helps project managers, general contractors, and operations leads determine total labor effort, working shifts, and billing costs required to complete projects on time.
