Obsolete Packaging Inventory Cost Calculator

Exclude approved usable or reworkable stock from affected quantity. This estimates operational exposure after a specification change, not an accounting-policy determination.

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.

THE CALCULATION

Exposure = Affected units × Book cost − Recovery + Disposal

stock = 10000; unit = 0.2; recovery = 100; disposal = 50 → Net entered inventory exposure = 1950 currency

UNDERSTAND THE CALCULATION

The formula, made clear.

Exposure = Affected units × Book cost − Recovery + Disposal

Exclude approved usable or reworkable stock from affected quantity. This estimates operational exposure after a specification change, not an accounting-policy determination.

How to use this calculator

  1. 01

    Confirm affected unused units, book cost per affected unit, confirmed total recovery, total disposal charge.

  2. 02

    Enter consistent units; zero means a confirmed absence of a charge or allowance.

  3. 03

    Review the arithmetic, rounding and limitations before using the result in a purchasing decision.

HOW TO VERIFY THIS RESULT

Check the displayed formula and units against your quotation. 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.
