Why Does ASCAP Use 100% and BMI Use 200%?
Why Does ASCAP Use 100% and BMI Use 200%?
If you’ve ever registered a song with ASCAP or BMI, you’ve probably noticed something confusing.
ASCAP uses a 100% system. BMI uses a 200% system.
Wait. Does that mean BMI pays twice as much?
Does ASCAP give songwriters less?
And why do the percentages look different when you’re registering the same type of song?
Let’s clear this up.
The short answer: ASCAP’s 100% system and BMI’s 200% system are different ways of accounting for songwriter and publisher shares. The numbers do not mean BMI pays twice as much as ASCAP.
Understanding the difference is important, especially if you’re an independent songwriter, producer, publisher, or artist managing your own music catalog.
First, Understand the Two Sides of Music Publishing
Before we get into the numbers, you need to understand that performance royalties for a musical composition are generally divided into two sides:
1. Writer’s Share
This is the portion allocated to the songwriters and composers who created the musical composition.
2. Publisher’s Share
This is the portion allocated to the publisher or the person who controls the publishing interest.
If you’re self-published, you may be entitled to both sides, depending on your rights and how your work is registered.
If you have a publishing agreement, your publisher may be entitled to some or all of the publisher’s share, depending on the agreement.
This distinction is the foundation of the 100% vs. 200% conversation.
How ASCAP’s 100% System Works
ASCAP uses a 100% accounting basis for the total performance royalty allocation.
In the conventional arrangement, that total is divided between:
- 50% writer’s share.
- 50% publisher’s share.
The writer’s share is allocated among the songwriters according to their agreed percentages. The publisher’s share is allocated according to the applicable publishing interests.
For example, imagine a hypothetical $100 performance royalty allocation:
| Allocation | Amount |
|---|---|
| Writer’s share | $50 |
| Publisher’s share | $50 |
| Total | $100 |
If you’re the songwriter and also control the full publishing interest, you may be entitled to both portions.
That means the total allocation could flow to you through the appropriate writer and publisher accounts.
How BMI’s 200% System Works
BMI approaches the same general writer/publisher division using a 200% accounting scale.
Instead of representing the entire allocation as 100%, BMI treats the writer and publisher portions as two separate 100% sides.
Here’s the breakdown:
- 100% writer’s share.
- 100% publisher’s share.
- 200% combined accounting total.
Using our hypothetical $100 example:
| Allocation | BMI accounting | Dollar equivalent |
|---|---|---|
| Writer’s share | 100% | $50 |
| Publisher’s share | 100% | $50 |
| Total | 200% | $100 |
Notice something?
The dollars are the same in this illustration. BMI is simply using a different accounting scale.
The 200% does not represent twice the money. It represents both sides of the composition royalty allocation.
BMI explains this directly in its Royalty Policy Manual.
So Why Does BMI Use 200% Instead of 100%?
The 200% system makes it possible to represent the writer and publisher portions as separate 100% allocations.
This can be useful when different people or companies control different interests in the same composition.
For example, a songwriter may retain their writer’s share while assigning some or all of their publisher’s share to a publishing company.
BMI’s accounting system can represent those interests separately without treating the writer and publisher portions as if they were one single 100% allocation.
ASCAP also tracks writer and publisher interests. The difference is how the total is represented in its accounting system.
The important thing is understanding what the percentages represent—not assuming one organization is paying more because its numbers are bigger.
Let’s Look at a Real-World Songwriting Example
Imagine two songwriters create a song together.
They agree to split the songwriting equally:
- Crystal: 50% of the writer’s share.
- Alex: 50% of the writer’s share.
For this example, assume the publishing interest is also divided equally between them and neither has assigned their interest to an outside publisher.
Under ASCAP’s 100% accounting basis:
| Participant | Writer’s share | Publisher’s share |
|---|---|---|
| Crystal | 25% | 25% |
| Alex | 25% | 25% |
| Total | 50% | 50% |
Under BMI’s 200% accounting basis:
| Participant | Writer’s share | Publisher’s share |
|---|---|---|
| Crystal | 50% | 50% |
| Alex | 50% | 50% |
| Total | 100% | 100% |
The percentages look different, but the relative interests are the same.
Each songwriter has half of the writer’s side and half of the publisher’s side in this example.
Important: These are simplified illustrations of the accounting scales, not instructions to enter the same percentages into every PRO registration form. Follow the specific organization’s registration instructions and make sure the underlying ownership agreements are accurate.
What If You’re Self-Published?
This is where independent songwriters need to pay attention.
If you write your own music and control your publishing, you may be entitled to both the writer’s share and publisher’s share.
You don’t necessarily need to have a separate publishing company to receive the publisher’s portion.
BMI explains that when a writer has no publisher, the publisher’s share may also be paid to the writer. Its system may display a publishing placeholder such as “Manuscript.”
ASCAP also provides for writers to receive the publisher’s share when they retain the applicable publishing interest.
But here’s the important part:
Being self-published does not automatically mean you own 100% of every song you participate in.
If you co-wrote the song, agreed to share ownership, signed a publishing agreement, or assigned rights to another party, those arrangements matter.
Your PRO registration should reflect your actual rights.
Does BMI’s 200% System Mean You Get Paid More?
No.
This is probably the biggest misconception surrounding the topic.
You cannot look at a BMI registration showing 200% and compare it to an ASCAP registration showing 100% and conclude that BMI pays twice as much.
The accounting scale alone does not determine the amount of money you receive.
Actual performance royalty distributions depend on several factors, including:
- The type of music use.
- The license fees collected.
- The number and nature of reported performances.
- The organization’s distribution methodology.
- The song’s registration and ownership information.
- The rights you control.
- Any applicable agreements with publishers or co-writers.
Two songwriters affiliated with different PROs may receive different payments for many reasons. The 100% vs. 200% accounting difference alone doesn’t explain those differences.
If you’re comparing ASCAP and BMI, look at their actual royalty policies, distribution practices, membership agreements, and services—not just the percentages.
What Should Independent Artists and Producers Remember?
If you’re creating music independently, here are the practical takeaways:
For songwriters:
Know your writer’s share, know your publisher’s share, and understand whether you control both.
For producers:
A production credit does not automatically give you a songwriting or publishing share. If you contributed to the composition, document the agreement.
For artists:
Don’t assume the person who recorded the song, paid for the beat, or released the master automatically owns the composition.
For publishers:
Make sure your publishing agreements and work registrations accurately reflect the rights assigned to your company.
And for everybody: keep your split sheets.
A clear agreement between collaborators is more important than trying to make percentages look the same across two different PRO systems.
Quick Reference: ASCAP vs. BMI
| ASCAP | BMI | |
|---|---|---|
| Accounting scale | 100% | 200% |
| Writer’s portion in conventional arrangement | 50% | 100% |
| Publisher’s portion in conventional arrangement | 50% | 100% |
| Combined accounting total | 100% | 200% |
| Does the scale mean more money? | No | No |
These are conventional accounting representations. Actual registration and payment treatment can vary with ownership, publishing agreements, and the rights assigned.
FROM THE SOUTHERN GIRL & CO. DESK
The music business can make simple things unnecessarily confusing.
You write a song, collaborate with a producer, agree on splits, register your work, and then somebody tells you BMI uses 200% while ASCAP uses 100%.
Naturally, you start wondering if you picked the wrong organization.
Don’t get caught up in the bigger number.
Understand the two sides of music publishing. Know what you own. Know what you’ve assigned. Keep your agreements in writing and make sure your registrations reflect the actual deal.
The goal isn’t to have the biggest percentage on paper. The goal is to understand your rights and collect the money you’re entitled to earn.
Because music is the creative part. Understanding the business is how you protect what you create.
