Warehouse Labor and Headcount Calculator
Size DC labor from inbound and outbound throughput, FTE and headcount by function, annual cost, cost-per-unit, and a peak-vs-average staffing comparison. Calculations run server-side.
Presets reshape rates & mix only, your volumes, wages, calendar, and shifts stay.

What this calculator does
This calculator estimates the labor needed to run a distribution center from daily inbound and outbound volumes. It returns full-time equivalents (FTE) and headcount by function (receiving, putaway, picking, packing and shipping), supervisor and maintenance headcount, annual cost, cost per unit and per order, and a comparison of staffing to peak versus staffing to average with overtime.
Inputs that matter
- Inbound: pallets received per day and floor-loaded cases per day.
- Outbound: pallets, cases and eaches picked per day, or a total picks per day split by percentage. Also orders per day, cases per pallet and eaches per case.
- Rates: units per hour for receive, putaway, pick, pack and load tasks. The each-pick rate follows the pick method you choose: manual, RF, voice or goods-to-person.
- Shifts and cost: shifts per day, hours per shift, a productivity factor, the fully burdened hourly wage, an overtime multiplier and working days per year.
- Indirect and peak: supervisor and maintenance span of control and wages, a peak factor and the number of peak days per year.
How it works
Each task is a stream. Daily hours are daily volume divided by the rate, and FTE is daily hours divided by effective hours per shift, which is hours per shift times the productivity factor. Streams roll up into the five functions, and headcount rounds each function up to whole people.
Direct FTE plus a support uplift gives operational FTE. Supervisors and maintenance technicians are staffed per shift: operational FTE is spread across shifts, divided by the span of control, rounded up and multiplied by the shifts.
Annual cost is operational FTE times working days times hours per shift times the wage, plus indirect staff at their own wages. Cost per unit divides annual cost by annual outbound units, converting cases and pallets to eaches. Cost per order divides it by annual orders.
The peak comparison costs two options. Staffing to peak hires operational FTE times the peak factor, rounded up. Staffing to average hires for the normal day and covers the peak gap with overtime on peak days at the overtime multiplier. The cheaper option is recommended, with the savings shown.
Frequently asked questions
- What is the difference between FTE and headcount?
- FTE is the fractional labor requirement: daily task hours divided by productive hours per shift. Headcount rounds up to whole people, so it is never lower than the FTE figure for the same function.
- What does the productivity factor do?
- It converts paid hours into effective hours. Effective hours per shift equal hours per shift times the factor, so a lower factor means more FTE for the same work.
- Should I staff to peak or to average?
- The calculator prices both. Staffing to peak pays for idle labor on non-peak days, while staffing to average pays overtime on peak days. It recommends the lower annual cost and shows the difference, which depends on your peak factor, peak days and overtime multiplier.
