How the calculation works
Royalty per copy is the selected royalty base multiplied by the royalty rate. Earned royalty is that amount times units sold. If an advance is recoupable, payable royalty begins only after earned royalty exceeds it.
Input guide and example
MSRP, wholesale price, and net receipts are different concepts. For example, a $40 MSRP at 5% produces $2.00 per copy, while a $14 net-receipts base at the same rate produces $0.70. Use the base defined by your agreement.
Assumptions and limits
Use one currency and enter the definitions, rates, and costs from your actual agreement, quote, or sales plan. This is a scenario calculator, not legal, tax, accounting, or commercial advice.
