Tiered Royalty Calculator

About this calculator

A tiered (or escalating) royalty structure pays a rising royalty rate once cumulative net sales pass a defined threshold — for example, 10% on the first 5,000 units sold, then 12.5% on everything beyond that — a common structure in book publishing contracts, music licensing, franchise agreements, and software or patent licensing deals. It rewards the licensor (author, artist, licensor, or IP owner) with a larger share once a product proves commercially successful, while giving the licensee (publisher, licensee, or distributor) a lower effective rate on the earlier, riskier sales.

Literary agents, publishers, licensing attorneys, and royalty-accounting departments use tiered-royalty math to calculate exactly what's owed each royalty period, since getting the bracket calculation wrong — applying the higher rate to the whole sales figure instead of only the portion above the threshold — is a common source of royalty statement disputes between authors/creators and their publishers or licensees.

This calculator takes your net sales figure, the sales threshold where the rate increases, and the royalty rates for each bracket, and returns the total royalty owed with the calculation broken out by tier.
