How it works

01

Enter the amount

The payment you are splitting: a royalty statement, a sync fee, a show fee, merch takings. Any currency.

02

Add the people

By percentages if you have agreed splits, or by parts for band maths: one part each is an equal split, two parts is a double share.

03

Read the payouts

Every person gets an exact figure, and the figures always sum to the amount. Copy the breakdown as text and send it to the group chat.

Why split maths goes wrong, and how this gets it right

Splitting money between collaborators sounds like arithmetic anyone can do, and then a three-way equal split of a real payment produces thirty-three point three three three recurring and someone rounds each share separately. Now the three payouts do not add up to the original amount, and somebody is quietly owed a cent, or paid one that does not exist. Across a year of statements, that is how spreadsheet arguments start.

This calculator works in whole cents from the start. Every share is rounded down, then the leftover cents are handed to the largest remainders, one each, until the total matches the payment exactly. The method has a name, largest remainder, and it is how election seats and invoice line items get allocated for the same reason: the parts must equal the whole.

The parts mode is for how bands actually talk. Nobody in a rehearsal room says twenty-eight point five seven percent. They say one share each, and the producer gets two. Enter it that way and the percentages and payouts are worked out for you.

A calculator settles one payment. If you want the same shares applied to every payment automatically, that is what Royalty Splits at Unchained do: set the percentages once on a release, and each collaborator receives their side of the earnings without anyone doing the maths again.

Split calculator questions, answered

What can I split with this?

Any single amount: a royalty payment, a sync placement fee, a show guarantee, merch revenue, a session buyout. It divides one number between people; what the number is comes from you.

What is the difference between percentages and parts?

Percentages are for agreed splits that must total exactly 100. Parts are for equal-share thinking: one part per person splits evenly, and giving someone two parts doubles their share. The tool converts parts to percentages for you.

Why do the payouts always add up exactly?

The calculator allocates in whole cents using the largest remainder method: round everyone down, then distribute the leftover cents to the largest fractional shares. Rounding each share separately can lose or invent cents; this cannot.

Does it handle uneven splits like 33.33 across three people?

Yes. Enter 33.33, 33.33 and 33.34, or switch to parts mode and give each person one part, and the cents are distributed so the total is exact either way.

Is this the same as a split sheet?

They are partners. A split sheet records who agreed to what, signed, before the money exists. This calculator applies those shares to an actual payment. We have a free split sheet generator as well.
