Who wrote what, and who gets how much? List everyone who wrote the song, say how much of the lyrics and how much of the music each wrote, and see each person's final share of the composition.
1. Decide how much of the song is lyrics and how much is music — 50/50 is the most common starting point, an instrumental is 0% lyrics. 2. Add every writer and say what percentage of the lyrics and of the music each one wrote; each column should come to 100%. 3. The final share column is each person's part of the whole composition.
Nothing you type leaves your browser. Write the agreed numbers down, have every writer sign, and keep a copy — the conversation is easiest the day the song is written, not the day it earns money.
A split sheet records ownership of the composition — the words and the melody — which is what collecting societies pay songwriters for. In Turkey that registration goes through MESAM or MSG; elsewhere through societies such as PRS, ASCAP or GEMA. Ownership of the recording (the master) is a separate agreement between artists, producers and labels.
This calculator does the arithmetic; it is not legal advice. For a contract, talk to your collecting society or a music lawyer.
Is 50/50 between lyrics and music a rule?
No, it is a convention many co-writers start from. The writers can agree any split, as long
as everyone signs the same numbers.
Does the producer get a share of the composition?
Only if they wrote part of the melody or lyrics, or the writers agree to include them. A
producer's payment for the recording is usually a separate fee or master royalty.
Is my data saved anywhere?
No. The calculator runs entirely in your browser and nothing is sent or stored.
