How do you calculate warehouse throughput capacity?

Multiply output per cycle by the available cycles to get gross capacity, then multiply by uptime and by first-pass yield. With 4 units/cycle over 480 cycles at 90% uptime and 97% yield, gross is 1,920 units and good capacity is about 1,676 units.

What is the difference between gross and good capacity?

Gross capacity (1,920 units in the example) is the theoretical maximum. Good capacity (about 1,676 units) is what survives after downtime removes 192 units and yield loss removes roughly 52 more.

What is a good first-pass yield for a pack or sort line?

Well-run fulfillment lines target 97-99% first-pass yield; below 95% the rework and re-handle burden starts to meaningfully cut into shippable capacity and labor.

Is downtime or yield hurting my capacity more?

Compare the two loss lines. In the example downtime costs 192 units and yield costs about 52 units, so an availability fix delivers nearly four times the capacity recovery of a quality fix — prioritize uptime first.

How is this different from OEE?

OEE multiplies availability, performance, and quality into one percentage. This calculator applies availability (uptime) and quality (first-pass yield) to a cycle-based output count to give a unit number you can commit to, rather than a percentage.

What counts as a cycle?

A cycle is one repetition of the throughput unit of work — a sorter pass, a pick tour, or a pack cadence. Available cycles is how many of those fit in the period after planned stops.

WMS, Warehouse Labor & Fulfillment calculator

Warehouse Throughput Capacity Calculator

Warehouse Throughput Capacity estimates how many good, shippable units a pick line, sorter, or pack station can actually produce in a period once you discount for downtime and first-pass quality. Operations planners and industrial engineers use it to set realistic daily commitments, size waves, and spot where capacity leaks away. Gross capacity — output per cycle times available cycles — is the number equipment vendors love to quote, but uptime losses and rework quietly erode it. Multiplying by uptime and first-pass yield gives the number you can safely promise to sales and carriers.

What this calculator does

Estimate warehouse throughput capacity for wms, warehouse labor and fulfillment using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when warehouse throughput capacity in wms, warehouse labor and fulfillment is being asked to take on more work and you need to know if there is room.
It computes gross capacity (output per cycle times available cycles) and good capacity (gross derated by uptime and first-pass yield), plus the downtime and yield losses.

Formula used

Gross warehouse throughput capacity = warehouse throughput capacity output per cycle × available warehouse throughput capacity cycles
Good warehouse throughput capacity = gross capacity × expected warehouse throughput capacity uptime × expected warehouse throughput capacity first-pass yield

Inputs explained

Units handled per equipment cycle:
Available cycles in the period:
Expected equipment uptime:
Expected first-pass yield:

How to use the result

Use it when setting a shift's shippable commitment, evaluating an automation upgrade, or diagnosing whether a capacity shortfall is a downtime or a quality problem.
It applies uptime and yield as flat multipliers on a single line; a network of stations with different bottlenecks needs each modeled separately.

Current U.S. benchmarks

On-highway diesel averages $4.58 per gallon this week (EIA), trending down over recent periods. Truck tonnage is up 3.4% year over year (ATA via FRED).
Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
