About this calculator
Every print run loses some material to makeready — the sheets a press or printer burns through calibrating color, registration, and speed before it produces a saleable copy. Digital presses waste very little, often under 1%, while offset presses commonly waste 3-8% of a run depending on job complexity and press condition, and screen printing loses shirts to misprints, ghosting, and setup tests at a similar 3-6% rate for typical shops. This calculator takes your ordered quantity, a waste percentage based on your process, and computes how many extra units to produce so you deliver the full order after normal spoilage, plus the added material cost of that overrun. It also flags overrun economics: since trade custom in printing allows delivering within 5-10% over or under the ordered quantity without penalty, it's often cheaper to print a small planned overrun than to run a costly second short makeready pass later.
Worked example
Using the values the calculator loads with:
Inputs
- Order quantity needed: 500
- Expected waste/spoilage rate: 5 %
- Unit production cost: 0.6 $
- Additional safety buffer: 2 %
Results
- Units to actually produce: 537
- Extra units for waste + buffer: 37
- Cost of overrun units: $22.20
- Total production cost: $322.20
What each field means
Inputs
- Order quantity needed
- The order quantity needed used in the calculation. Starts at 500 so you have a working example on load.
- Expected waste/spoilage rate (%)
- The expected waste/spoilage rate used in the calculation, measured in %. Starts at 5 % so you have a working example on load. Accepted range: 0–40 %.
- Unit production cost ($)
- The unit production cost used in the calculation, measured in $. Starts at 0.6 $ so you have a working example on load.
- Additional safety buffer (%)
- The additional safety buffer used in the calculation, measured in %. Starts at 2 % so you have a working example on load. Accepted range: 0–20 %.

FAQ
What's a normal waste rate by process?
Digital press: under 1-2%. Offset litho: 3-8% depending on job length and press setup complexity. Screen printing: 3-6% from misprints and press adjustments. Wide-format/vinyl: 3-10% from trim, registration, and material defects.
What is trade custom overage/underage?
Long-standing printing industry practice (and often written into contracts) allows delivering 5-10% over or under the ordered quantity without price adjustment or penalty, because exact-count production runs are impractical on many processes. Confirm the specific percentage in writing with your printer.
Should I print extra on purpose?
Often yes for reorderable items like business cards or standard apparel — printing 5-10% more costs little in marginal material but avoids a second full setup charge if you need a few extra weeks later.
How does waste rate change with job complexity?
More colors, tighter registration tolerances, and larger sheet sizes all raise waste because more can go wrong per unit and makeready takes longer to dial in. A simple one-color job wastes far less than a 6-color process job.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
