How this service works
Print book royalty per copy from list price, printing cost and royalty rate, plus break-even price and total.
Output
Returns royalty per copy (exact and rounded), total royalty for the specified number of copies, break-even list price, author share as a percent of list price, the royalty model used, and a summary. May include disclaimer and degraded flag if inputs are unusual.
Example use cases
Self-publisher pricing a new paperback
“I'm launching a paperback with a $16.99 list price, $4.20 printing cost, and a 60% royalty rate — what's my royalty per copy and what's the break-even list price I should be aware of?”
Comparing net vs list royalty models
“Can you calculate my royalty per copy under both the list and net models? My book lists at $22.00, printing costs $5.50, and my royalty rate is 70%.”
Projecting total earnings for a print run
“If I sell 500 copies of my print book at a $14.99 list price with $3.80 printing cost and a 60% royalty rate, what are my total royalties and royalty per copy?”
Technical details
Endpoint
GEThttps://publishing-calc.x402tookit.com/print-royalty?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, formula-based royalty calculation for a print book — especially when you have a specific list price, per-copy printing cost, and royalty rate in hand and want both per-copy and total royalty figures along with break-even analysis. Prefer this over manual calculation or generic spreadsheet tools when building a publishing workflow agent or helping authors evaluate pricing decisions quickly.
Side effects
- Missing required queryParams (listPrice, printCost, royaltyRate) returns an error
- Royalty rate entered as a decimal (e.g. 0.60) instead of percent (60) may yield unexpected results
- List price lower than printing cost will produce a negative or zero royalty per copy
- Invalid model value (not 'list' or 'net') may fall back to default or return an error
- Non-numeric values for numeric fields will cause a validation failure
