How do you calculate packing labor cost?

Multiply cartons packed by labor cost per carton, divide by the pack-station efficiency, then add fixed setup cost. With 4,000 cartons at $1.10 each, 85% efficiency and $1,500 setup, that is 4,000 x 1.10 / 0.85 + 1,500 = $6,676.

What is the packing labor cost per carton in the example?

$1.67 per carton, the $6,676 total divided by 4,000 cartons. That is higher than the $1.10 base rate because inefficiency and the $1,500 fixed setup are loaded onto every carton.

What is a good packing labor cost per carton?

For manual e-commerce pack-out, $0.75 to $1.50 per carton is typical; sub-$0.50 usually means automation or very high volume. The $1.67 result sits slightly high, driven by the 85% efficiency and fixed setup on modest volume.

Why does per-carton cost fall as volume rises?

The $1,500 setup is fixed, so it spreads thinner across more cartons. At 8,000 cartons instead of 4,000 the same setup adds only $0.19 per carton instead of $0.375.

Variable vs fixed packing cost, what is the difference?

Variable cost ($5,176 here, efficiency-loaded) scales with cartons packed; the fixed adder ($1,500) is materials and handling setup you pay regardless of volume. Separating them tells you your breakeven and marginal pack cost.

Does pack-station efficiency raise or lower the cost here?

Efficiency below 100% raises modeled labor: the calculator divides the variable component by 0.85, because a station running below the assumed rate needs more paid time per carton.

Packing Labor Cost Calculator

Packing labor cost is the fully-loaded cost of getting product into shippable cartons, the pack-station wages plus fixed materials and handling setup, spread across the cartons you actually pack. Fulfillment managers and 3PL operations leads use it to price pack-out services, decide when a pack line justifies automation, and defend labor budgets to finance. Because packing is one of the last touches before a carton ships, small per-carton drifts multiply fast across thousands of orders. This calculator separates the variable pack labor from the fixed adder so you can see exactly where the money goes.

What this calculator does

Estimates the labor cost to pack, seal, and label cartons at the fulfillment pack stations.
A packing supervisor uses it to cost a packing line before a peak-season staffing plan.
It computes total packing labor cost and cost per carton by multiplying cartons by labor per carton and a pack-station efficiency factor, then adding a fixed setup cost.

Formula used

Total pack cost = cartons x labor per carton / (efficiency % / 100) + setup cost
Pack cost per carton = total pack cost / cartons

Inputs explained

Cartons Packed per Period:
Pack Labor Cost per Carton:
Pack Station Labor Efficiency:
Materials & Handling Setup Cost:

How to use the result

Use it when quoting pack-out work, building a labor budget for a pack line, or comparing a manual pack station against a semi-automated one.
The efficiency percentage here scales the variable labor down as a multiplier, it is not a utilization loss adder, so a value below 100% will reduce, not inflate, the modeled labor spend.

Current U.S. benchmarks

On-highway diesel averages $5.65 per gallon this week (EIA), trending up over recent periods. Truck tonnage is up 0.8% year over year (ATA via FRED).
Manufacturing hourly earnings average $30.35 (BLS, Jul 2026), up 4.2% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 481k open positions nationally (BLS JOLTS).
