Units per Labor Hour Calculator
Measure warehouse productivity per worked hour — picking, packing, or receiving. Enter total labor hours or a crew and its shift, and add a wage to turn throughput into labor cost per unit.
Units per labor hour
The core productivity number
Units per labor hour is the simplest read on warehouse productivity: how much work gets done for each hour on the clock. Divide units processed by the labor hours that produced them. For a crew, labor hours is workers times the hours each of them worked — three people for two hours is six labor hours, not two.
UPLH = units processed ÷ total labor hours
Turning it into cost
Add an hourly wage and UPLH becomes money: labor cost per unit is the wage divided by UPLH. It’s the number that tells you what each pick or pack actually costs in labor — and what a productivity gain is worth. A crew doing 80 units an hour at $18 is about 22.5¢ of labor per unit.
UPLH is most useful against your own baseline — shift to shift, site to site — not a universal target. The task and product set the bar.
