How to Use This Calculator
This tool walks through every layer a sync deal actually touches before money lands in your bank account. Here's what each section does:
- Deal Structure: Enter the gross fee as quoted in the deal. If you're a one-stop, enter both the master use fee and the sync (composition) fee separately — you collect both.
- Commission: Enter the percentage your library or agent retains. Sync libraries typically take 25–50%; dedicated agents take 15–35%. Direct deals have 0% commission.
- Writer & Publishing Splits: Any co-writer share reduces your slice of the composition fee. A publishing administrator (Songtrust, DistroKid Publishing, etc.) typically takes 10–25% of composition royalties.
- Tax: The US SE tax estimate uses the IRS Schedule SE rate: 15.3% on 92.35% of net earnings. This is separate from income tax — the tool shows SE tax only.
- PRO backend: Enter your estimate for performance royalties from ASCAP, BMI, SESAC, etc. These are not commissionable and are shown separately from the upfront fee calculation.
When Would You Use This?
- A music supervisor emails you with an offer — quickly model whether to accept or counter.
- Comparing two library deals with different commission structures.
- Estimating quarterly SE tax to avoid IRS underpayment penalties.
- Explaining deal economics to a co-writer or producer before signing.
- Planning cash flow across a catalog of multiple placements in a year.
The Two Licenses Every Sync Deal Requires
Every music placement legally requires two separate licenses regardless of how the deal is structured:
- Master use license: Covers the specific sound recording. Paid to whoever owns the recording — you as an indie artist, or a label if you're signed.
- Sync license: Covers the underlying composition (melody, chords, lyrics). Paid to the songwriter or publisher.
If you wrote and recorded the song yourself (a "one-stop"), you own both sides and collect both fees — a significant advantage that makes you faster and easier to license than a major-label act where two separate entities must each sign off.
Understanding Library Commission Structures
Most sync libraries operate on a commission model, retaining a percentage of each placed fee. Ranges from industry research:
- Non-exclusive stock/per-transaction libraries (AudioJungle, Pond5): typically retain 30–50%, artists keep 50–70%.
- Premium curated sync libraries (Musicbed, Marmoset): typically 40–50% commission, but higher placement value and fees.
- Sync agents (direct pitching): 15–35% commission on placements they secure.
- Direct deal (no intermediary): 0% commission — you keep the full negotiated fee.
Crucially: in most standard library agreements, PRO performance royalties flow directly to your PRO registration and are not subject to library commission. Only the upfront sync fee is split.
US Self-Employment Tax on Sync Income
Sync licensing fees are ordinary self-employment income in the US. The IRS Schedule SE calculation is: net earnings × 92.35% × 15.3%. The 92.35% factor mimics the employer deduction that salaried workers receive. You can deduct 50% of the resulting SE tax from your adjusted gross income when filing. Note: this is only SE tax — federal and state income tax is calculated separately on your total taxable income for the year.
