THE NUMBERS, EXPLAINED
How to use this calculator.
Artist proofs are additional to the numbered edition and are not included in numbered stock. Sold and reserved copies are disjoint counts.
Start with your inputs
Enter numbered edition size (count), artist proofs outside numbered edition (count), reserved numbered copies (count), sold numbered copies (count). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Numbered edition size (count) | 100 |
| Artist proofs outside numbered edition (count) | 10 |
| Reserved numbered copies (count) | 15 |
| Sold numbered copies (count) | 20 |
A worked example
With the example inputs above, total physical edition inventory is 110. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Total physical edition inventory | 110 |
| Available numbered copies | 65 |
| Numbering labels | Numbered 1–100; artist proofs AP 1–10 |
How this is calculated
Total physical edition inventory
Add numbered edition and separate artist proofs.
Available numbered copies
Subtract reserved and sold copies from the numbered edition.
Numbering labels
Use separate labels for numbered copies and artist proofs.
Symbols and units
- a
- Numbered edition size (count)
- b
- Artist proofs outside numbered edition (count)
- c
- Reserved numbered copies (count)
- d
- Sold numbered copies (count)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Artist proofs are additional to the numbered edition and are not included in numbered stock. Sold and reserved copies are disjoint counts.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Total physical edition inventory; Available numbered copies; Numbering labels. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Artist proofs are additional to the numbered edition and are not included in numbered stock. Sold and reserved copies are disjoint counts.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
