Print Run Spoilage and Overage Calculator

A print run must cover fixed setup sheets, percentage-based running spoilage, finishing loss, and non-sellable samples. Because percentage losses affect the quantity entering later stages, divide the target by the combined yield instead of merely adding all percentages. This calculator then rounds the press quantity to complete cartons for a practical production order.

Sellable units above the requested quantity.

How the calculation works

The calculator applies this relationship to the inputs above. Keep every measurement in the unit shown.

press quantity = (ordered units + setup waste + samples) ÷ running yield ÷ bindery yield

Sellable units required5000 units

Fixed setup waste180 sheets

Running spoilage2.5 %

Finishing loss1.5 %

Units per production carton250 units

Worked example

Use this example to check the calculator by hand before relying on a result.

Combine variable yields

Each stage acts on the surviving quantity.

97.5% × 98.5% = 96.04%

Include setup sheets

This is the unrounded press requirement.

(5,000 + 180) ÷ 96.04% = 5,393

Round to cartons

Production rounding creates a modest overage.

ceil(5,393 ÷ 250) × 250 = 5,500

Assumptions behind the result

• Setup waste is fixed.
• Spoilage rates are independent stage yields.
• All units use the same production path.
• Carton rounding is appropriate.
• Contractual overage tolerances are checked separately.

Mistakes that change the answer

• Adding spoilage percentages directly.
• Applying setup waste after percentage loss.
• Promising every printed sheet as sellable.

Questions about print run spoilage and overage calculator

Why divide by yield?

Adding a loss percentage to the target can still leave the final output short because some of the added units are also lost.

Should samples be included?

Add required samples to the sellable target or fixed waste, depending on where they leave the production flow.

What if spoilage changes by run size?

Use historical rates for a comparable job and separate fixed makeready from variable spoilage.
