PACKAGING PLANNING / CALCULATOR
Case Pack Calculator
Work out inner packs, master case counts, and gross weight for retail and e-commerce distribution.
The Case Pack Calculator breaks down complex packaging hierarchies into inner packs, master cases, and gross pallet weights for wholesale distribution and retail supply chains.
Instant planning estimate based on the mathematical formula shown below.
MATHEMATICAL FORMULA
Master Cases = Total Units ÷ (Inners per Master × Units per Inner)
Every calculation is executed dynamically in real time. We display exact working equations so engineers, builders, and makers can audit the arithmetic before acting on estimates.
How This Calculation Works
1. Enter total required units. 2. Enter units per inner box and inner packs per master carton. 3. Input single unit weight to compute gross freight weight.
Worked Real-World Example
For 2,400 units packaged 6 units per inner pack and 4 inners per master case (24 units/case): Total master cases = 2,400 ÷ 24 = 100 cases (400 inner packs). At 0.75 lbs per unit, net cargo weight = 1,800 lbs.
Assumptions, Tolerances & Limitations
Ensure the master case dimensions comply with automated conveyor sorting limits (max 30-36 inches length) at major distribution hubs.

STEP-BY-STEP GUIDE
How to use the Case Pack Calculator
Follow the step-by-step procedure below to gather your measurements and generate reliable estimates for your project.
Collect physical measurements, equipment ratings, or recipe proportions without premature rounding.
Ensure measurements match labeled field units for mathematical consistency.
Review final primary and secondary values, applying recommended waste or safety tolerance factors.
FREQUENTLY ASKED QUESTIONS
What is the difference between an inner pack and a master case?
An inner pack is a sub-box or bundle holding a small count of retail units (e.g. 6 units), while a master case holds multiple inner packs (e.g. 4 inner packs = 24 units total) for bulk transport.
Why do retailers require specific case pack counts?
Retailers require standardized case packs to match store shelf depth and replenishment velocities without cluttering retail backrooms with loose inventory.
How do I calculate total cases needed from loose units?
Divide total required units by (units per inner × inners per master case). Round up if you must order complete master cases.
