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.
Label only. No exchange-rate conversion.
Invoice at entered overrun
Rounding up models a conservative whole-unit purchase allowance.
Actual tolerance, billing and acceptance must be confirmed with the supplier.
No underrun, freight changes, taxes or fixed charges are included.
Extra units = ceil(Ordered units × Overrun/100); Invoice = (Ordered + Extra) × Unit price
Inputs: Ordered units = 20000 units; Allowed positive overrun = 5 %; Price per delivered unit = 0.3 currency. Result: Invoice at entered overrun = 6300 currency; Extra delivered units = 1000 units; Extra purchase cost = 300 currency.Saved calculations stay in this browser.

How sensitive is this result to your assumptions?
Vary one input and inspect invoice at entered overrun
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.
Some custom packaging orders allow a quantity tolerance. This models the positive overrun scenario when all delivered units are billed at the quoted unit price; it does not interpret your contract.
How to use this calculator
- 01
Enter ordered units, allowed positive overrun, price per delivered unit.
- 02
Use a consistent unit and cost boundary across inputs.
- 03
Review the result, whole-unit rounding and limitations before placing an order.
A calculation you can check
A 20,000-unit order with a 5% overrun can add 1,000 units and €300 at €0.30 per unit.

Inputs: Ordered units = 20000 units; Allowed positive overrun = 5 %; Price per delivered unit = 0.3 currency. Result: Invoice at entered overrun = 6300 currency; Extra delivered units = 1000 units; Extra purchase cost = 300 currency.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.
