Protective Packaging Change ROI Calculator
Evaluate a protection change using measured or explicitly assumed before/after rates. Costs belong to the same scope and period; trial differences are not proof of causation.

First time using this calculator?
Replace the example values with figures from your supplier sheet or measurements. Choose the unit beside each value. Results update as you type; fix any highlighted field before using the result.
GSM means grams per square metre. Net weight excludes the core and other packaging. MOQ means the minimum order quantity. An optional field can stay blank unless the result you need depends on it.
Prices keep the selected currency; changing its label does not convert an exchange rate. Save or export the result after checking your inputs.
Help with net cost per damage incident
Use material weight only. Subtract the core, pallet and outer wrapping from a gross shipment or roll weight. Find the net value on the supplier sheet or weigh it separately.
Label only; no currency conversion.
Net benefit in entered period
Net period benefit = Q × ((Baseline − Trial)/100 × Incident cost − Extra protection) − Change costs
quantity = 10000; before = 2; after = 1; loss = 40; extra = 0.15; setup = 500 → Net benefit in entered period = 2000 currency; Avoided damage expense = 4000 currency; Return on incremental protection spend = 100 %Saved calculations stay in this browser. No account or cloud backup is created.

Vary one input and inspect net benefit in entered period
All other entered inputs stay fixed. Ranges are your scenarios, not statistical confidence or supplier performance predictions. This uses the same validated calculator engine.
The formula, made clear.
Evaluate a protection change using measured or explicitly assumed before/after rates. Costs belong to the same scope and period; trial differences are not proof of causation.
How to use this calculator
- 01
Confirm the specification and measurement boundary: Shipments in explicit period, Baseline damage fraction, Trial damage fraction, Net cost per damage incident, Additional protection per shipment, One-time change and validation costs.
- 02
Replace illustrative defaults with job measurements and confirmed quotations.
- 03
Check the result and the limitations before comparing equivalent supplier offers.

Use measured GSM, net weight and actual layout dimensions where available. Default densities are planning assumptions, not certified material properties. Calculated cost does not certify strength, compatibility or safe loading.
