Film Price per Roll Calculator
Estimate the material value of a roll from net film weight and price per kilogram, or from area and price per square metre. Optional dimensions put the roll value on a running-metre basis.

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 film weight
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.
Help with film price per kg
Use the price for one kilogram of the quoted material, excluding freight unless the quote explicitly combines them.
Label only. No exchange-rate conversion.
Additional measurements (optional)
These are only needed for additional result units or a more detailed estimate. Entered values still affect the result when this section is closed.
Optional: enables price/m² from net weight.
Help with film 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.
Help with web width
Measure the full width of the flat material from edge to edge, rather than the width of one finished pack. Choose the matching unit.
Roll material value
Enter GSM or both roll width and length to calculate an equivalent price/m².
Roll value = net film kg × price/kg
80 × 3 = 240/rollSaved 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 roll material value
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.
A roll price is meaningful only alongside the quantity of film it contains. The weight method multiplies net film kilograms by the kilogram price; the area method multiplies purchased surface area by the area price. Keep the quantity and price basis paired correctly. Entering gross roll weight into a net-material quotation would also price the core and protective packaging as film.
How to use this calculator
- 01
Choose the weight or area pricing method.
- 02
Enter the corresponding net quantity and supplier unit price.
- 03
Supply roll dimensions where requested to express the same material value per square metre or linear metre.

Default densities are planning assumptions, not certified material properties. Calculated cost does not certify strength, compatibility or safe loading.
