Slitting Plan Comparison Calculator
Compare two explicit equal-width plans after checking edges and knife allowances. Different finished widths must serve the intended demand; maximum material yield alone does not choose a production plan.

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.
Plan A finished-width yield
Finished yield = Slit width × Lanes ÷ Master width
web = 1000; trim = 20; a = 240; na = 4; b = 190; nb = 5; gap = 0 → Plan A finished-width yield = 96 %; Plan B finished-width yield = 95 %; B minus A yield = -1 percentage pointsSaved calculations stay in this browser. No account or cloud backup is created.

The formula, made clear.
Compare two explicit equal-width plans after checking edges and knife allowances. Different finished widths must serve the intended demand; maximum material yield alone does not choose a production plan.
How to use this calculator
- 01
Confirm master width, combined reserved edges, plan a slit width, plan a lanes, plan b slit width, plan b lanes, separation allowance.
- 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.
