Royalty Split Waterfall Calculator

Reconcile fees, recoupment and collaborator splits down to the exact cent.

The Royalty Split Waterfall Calculator runs gross receipts down a four-step waterfall — gross, minus the platform or distributor fee percentage, minus the recoupable balance, leaving a distributable pool that is then divided between named collaborators by percentage. Splits are allocated in whole cents and normalised against the total percentage entered, with the last payee taking the rounding remainder so the payouts always add back to the pool exactly. It is for creators, producers and small labels reconciling a statement or agreeing a split sheet before money moves.

Why use Royalty Split Waterfall Calculator

• Reconciles to the cent

  Allocates in integer cents and gives the final payee the remainder, so the sum of the payouts equals the distributable pool with no drift.

• Recoupment capped at what exists

  Recoupment can never exceed post-fee receipts, so an unrecouped balance leaves a zero pool rather than a negative one.

• Handles splits that do not total 100

  Percentages are normalised against the total you entered and the entered total is shown, so a 105% or 98% split sheet is flagged rather than silently mis-paid.

Common use cases

• A distributor statement shows 100,000 gross with a 15% fee and a 10,000 advance still to recoup, and you need to tell three collaborators what each is actually owed.
• Your split sheet says 60/25/15 but the percentages you were given add to 105 — you want to see what each share becomes once they are normalised.
• A payout run keeps ending up one or two cents off the pool total, and you need an allocation where the remainder is assigned to a named payee instead of vanishing.
