Corrugated Box Material Cost Calculator
Estimate board material cost per actual corrugated blank and per 1,000 boxes. Price the board by kilogram or square metre without inventing a blank from finished dimensions.

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 actual board gsm
GSM is the weight of one square metre of material, in grams. Find it on the supplier specification; use the complete laminate value for layered film.
Unit label only. No currency conversion.
Additional measurements (optional) — some values entered
These are only needed for additional result units or a more detailed estimate. Entered values still affect the result when this section is closed.
Board material cost per blank
Uses actual blank dimensions. Finished internal or external package dimensions do not establish an exact die-line blank.
Printing, cutting and gluing are excluded unless explicitly entered in the additional conversion field. No process waste is included.
Material/blank = actual blank area × price/m²; price/m² = price/kg × GSM ÷ 1,000 when quoted by mass
0.2 × 0.4 = 0.08/blank; additional conversion 0 gives 0.08/boxSaved calculations stay in this browser. No account or cloud backup is created.

How sensitive is this result to your assumptions?
Vary one input and inspect board material cost per blank
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.
Blank dimensions define the purchased board allocation for one box. Area pricing can be applied directly, while kilogram pricing first needs complete-board GSM. This cost retains the board consumed by the blank, including material subsequently removed by slots or cutouts. A finished supplier quote may include operations beyond the board material estimated here.
How to use this calculator
- 01
Enter the actual production blank length and width.
- 02
Select the board price basis and enter its matching price and GSM.
- 03
Add a separate conversion charge if needed, then compare board-only and conversion-inclusive costs.
A calculation you can check
The example allocates the cost of a specified corrugated board to one known box blank and scales it to a thousand-box material budget.
- Actual blank width
- 500 mm
- Actual blank length
- 400 mm
- Actual board GSM
- 500 g/m²
- Board price on selected basis
- 0.8 EUR
- Converting / printing / gluing per box
- 0 EUR/unit
0.2 × 0.4 = 0.08/blank; additional conversion 0 gives 0.08/boxCheck 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.
