Song Royalty Split Calculator

Song royalties flow from several sources: streaming, radio airplay, sync licensing, and mechanical licenses. When a song has multiple co-writers or co-producers, the total royalty is divided by a split sheet agreed on before or just after the song is written.

What this calculator does

It works from gross revenue down to what each collaborator actually receives, in three steps:

1. Gross revenue minus the platform cut (the streaming service or store’s share)
2. minus the distributor cut (DistroKid, TuneCore, CD Baby, a label)
3. the remainder split between contributors, either equally or by role

Each share = Gross × (1 − platform%) × (1 − distributor%) × ownership fraction

The two deductions are the part most split calculators leave out, and they are usually larger than any disagreement about the split itself. A 30% platform cut plus a 15% distributor cut means only 59.5 cents of every dollar reaches the writers before anyone argues about percentages.

The role-based split this page uses

Choosing “role-based” applies these weights, then normalises them to 100%:

Only the roles covered by your contributor count are used. Two contributors means lyrics and melody at 35 each, normalised to 50/50. These are a starting point for a conversation, not an industry standard, because no such standard exists. The one genuinely conventional number is that lyrics and melody are usually treated as equal halves of a song.

A caution about the producer weight. Giving a producer 20% of the publishing assumes they contributed to the composition. A producer who only made the beat traditionally takes a flat fee or a separate producer royalty on the master, not a slice of the publishing. If that describes your situation, drop the contributor count by one and pay the producer separately, or the split sheet will give away 20% of your songwriting income for work that was never songwriting.

Where the other 50% goes. Publishing has two sides: the writer’s share and the publisher’s share, each 50% of the whole. This calculator divides the money you actually receive. If you are self-published you hold both sides and the figures below are the full amount. If you have a publishing deal, your publisher keeps their side and you should halve everything here.

Worked example

A song grosses $4,200. Spotify’s platform cut is 30%, DistroKid takes 15% of what is left, three contributors split the rest equally.

• After the platform cut: $4,200 × 0.70 = $2,940
• After the distributor cut: $2,940 × 0.85 = $2,499
• Each of the three: $833.00

Switch to role-based with those same three contributors and the weights become 35/35/20, normalised to 38.9/38.9/22.2, so the lyricist and composer take $971.83 each and the producer $555.34, the extra cent being the rounding remainder, which this page hands to the last contributor so the shares always add up to the net.

Important nuances:

• Producers who co-write melody or lyrics may also hold a writer’s share; producers who only contribute the beat typically receive a flat fee or a separate producer royalty agreement, not a publishing split.
• Mechanical royalties (for song reproductions, CDs, downloads, streams) are separate from performance royalties and are collected by different organizations (e.g., Harry Fox Agency, DistroKid Publishing).
• Always sign a split sheet before releasing a song. Verbal agreements almost never hold up legally.
• In the US, statutory mechanical rate is 9.1 cents per copy (streams use a more complex formula).

Reference rates: Spotify pays roughly $0.003–$0.005 per stream to rights holders total; the individual writer receives their ownership fraction of the songwriter’s portion of that.
