An odd-page duplex pack
20 invoice packs with two invoice pages and three supporting pages each have five pages per pack. One copy printed on two sides needs three sheets per pack, or 60 sheets for 100 printed pages, leaving 20 unused planned sides.

Free Invoice Print Pack Planner
Estimate a print run when each invoice copy starts on a fresh sheet and its supporting pages stay with it. This is a count plan; the tool does not inspect PDFs, print files or determine delivery requirements.
What you can do here
Plan paper sheets for separate invoice packs using entered invoice pages, supporting pages, copy count and one- or two-sided printing.
Built for real invoice workflows
Verify the approved package and recipient before preparing a physical delivery.

Calculation notes
How the result is calculated
Pages per pack = invoice pages + supporting pages. Sheets per copy = ceil(pages per pack / printed sides per sheet). Total printed pages = pack count × copies × pages per pack; total sheets = pack count × copies × sheets per copy. Unused planned sides = total sheets × sides per sheet − printed pages. Every copy begins on a fresh sheet. Assumes uniform pack size and excludes covers, separators, spoilage and reprints unless included explicitly in the page inputs.
Formulas and examples reviewed October 2, 2026. Illustrative figures; no tax or contractual determination.
A second copy
Two copies of the same 20 packs require 120 sheets and 200 printed pages. Copies remain separate packs; no paper reserve is added automatically.
Questions about this calculation
Can I combine mixed pack lengths here?
The model uses one uniform size. Group equal-sized packs and calculate separately, or count each actual pack.
Does unused planned capacity mean blank PDF pages?
No. It describes sheet sides left unused under the entered packing rule, not pages found in a file.
How to use it
1
Enter distinct invoice packs, invoice pages and supporting pages per pack.
2
Enter copies of each pack and one or two printed sides per sheet.
3
Review page and sheet counts, then verify actual document versions, ordering and printer settings.
Why it helps
Round sheets within each separate pack.
Avoid using the back of one client's final sheet for another client's document.
Keep support pages and extra copies in the count.
