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 order quantity a
Enter the usable quantity you actually need. Waste, pack rounding or minimum order effects are added separately where required.
Help with order quantity b
Enter the usable quantity you actually need. Waste, pack rounding or minimum order effects are added separately where required.
Label only; no exchange-rate conversion.
A approximate period cost
Approximate period cost = ceil(Demand/Batch) × (Batch × Price + Order expense) + Batch/2 × Annual holding expense
annual = 120000; a = 10000; b = 30000; pa = 0.1; pb = 0.09; fee = 100; hold = 0.02 → A approximate period cost = 13300 currency; B approximate period cost = 11500 currency; A full-batch surplus = 0 units; B full-batch surplus = 0 unitsSaved calculations stay in this browser.

The formula, made clear.
Model full equal batches, constant consumption and average cycle stock of half a batch. Show final surplus separately. The holding approximation excludes extra retained final surplus and safety stock.
How to use this calculator
- 01
Confirm units over one 12-month scenario, order quantity a, order quantity b, price per unit a, price per unit b, fixed expense per order, annual holding expense per average unit.
- 02
Enter consistent units; zero means a confirmed absence of a charge or allowance.
- 03
Review the arithmetic, rounding and limitations before using the result in a purchasing decision.

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.
