How do regulators tell a legal MLM from an illegal pyramid scheme? Learn the FTC's actual test, why there is no percentage rule, and how it applies to Herbalife.

Almost every controversy about Herbalife, and about direct selling generally, traces back to one question: where is the legal line between a legitimate multi-level marketing (MLM) business and an illegal pyramid scheme? The honest answer is more technical than most explainers admit, and getting it right matters more than any single company. This piece lays out the framework U.S. regulators actually use, then applies it to Herbalife's post-2016 structure.

What Makes a Pyramid Scheme Illegal

Multi-level marketing itself is legal. It is a distribution model where independent sellers earn money from their own sales and, in many plans, from the sales made by people they recruit into a "downline." The Federal Trade Commission publishes guidance on how MLMs should comply with the law rather than a blanket prohibition on the model.

What the FTC condemns is a specific structure. In its description, a pyramid scheme is one where participants pay for the right to sell a product and the right to earn rewards for recruiting more participants, where those recruiting rewards are unrelated to sales of product to real end users. The defining problem is that the money flows from recruitment, not from genuine consumer demand. When that happens, people at the bottom, who join last and can no longer find new recruits, are mathematically set up to lose.

The core legal principle, drawn from decades of cases such as Koscot, BurnLounge, and Vemma, is that a lawful MLM's compensation must be based on actual sales to real customers who are not just buying to qualify for recruitment rewards.

Why There Is No Simple Percentage Test

Here is the part that most consumer articles get wrong. There is a widespread belief that an MLM is legal as long as a fixed share of its sales (often quoted as 50% or 70%) goes to retail customers outside the network. The FTC's own guidance rejects this. It has stated plainly that there is no percentage-based test and no safe harbor for a compensation plan under the FTC Act.

Instead, regulators look at how the plan operates in practice. Relevant factors include:

  • Whether the compensation structure pushes participants to buy product for reasons other than real personal or customer demand, a pattern known as "inventory loading."
  • Whether recruiting is effectively required to earn meaningful rewards.
  • How the opportunity is marketed, including the earnings claims made to prospects.
  • What actually happens to participants over time.

A company can sell real, even high-quality products and still run an unlawful compensation structure. Conversely, having many genuine retail sales does not automatically make a plan legal if the incentives still reward recruitment above real selling. The analysis is fact-intensive and specific to each plan, which is exactly why blanket "X% makes it legal" claims are unreliable.

Buyback policies matter too. When participants cannot return unsold inventory, courts have treated the absence of refund protection as evidence pointing toward a pyramid structure, because the company keeps money that has no link to outside demand.

How This Framework Applies to Herbalife

Herbalife's 2016 FTC settlement is a useful case study in the difference between the general legal test and a company-specific remedy.

The settlement did not declare Herbalife an illegal pyramid scheme, and no court ruled that it was. It also did not ban Herbalife's direct-selling model. What it did was impose specific, measurable requirements designed to force the compensation plan to track real sales. Under the consent order, Herbalife must categorize members as customers or business builders, base at least two-thirds of distributor rewards on verified retail sales, and ensure that at least 80% of its net U.S. sales go to genuine buyers, with penalties to top distributors' rewards if that threshold is missed. An Independent Compliance Auditor monitors this for seven years.

One important clarification: those percentages are terms the FTC negotiated for Herbalife specifically. They are not the universal legal definition of a lawful MLM. The FTC has been explicit that no fixed percentage decides the question for the industry as a whole. So the accurate way to read Herbalife's numbers is as remedial guardrails placed on one company, not as the line every MLM must clear. This distinction is easy to blur and worth stating clearly, because conflating a company's settlement terms with the general law produces confident but incorrect claims.

What This Means for Someone Evaluating an Opportunity

For a prospective participant, the regulatory framework translates into practical due diligence. The question is not "does this company have products," because a pyramid can have products. The better questions are whether you can earn without recruiting, whether you would be pressured to buy inventory to advance, whether there is a genuine refund policy for unsold stock, and what the company's own income disclosure shows about typical earnings. Those signals map directly onto the factors regulators weigh.

Frequently Asked Questions

What legally separates an MLM from a pyramid scheme?

An MLM is lawful when compensation is based on real sales to genuine customers. It becomes an illegal pyramid when rewards flow primarily from recruiting new participants rather than from product sold to people who actually use it. The FTC decides this by examining how the plan works in practice.

Is there a rule that a set percentage of sales must go to real customers?

No. This is the most common misconception. The FTC has stated there is no percentage-based test and no safe harbor under the FTC Act. The analysis is fact-specific, not a fixed threshold.

Can a company with real products still be a pyramid scheme?

Yes. Selling real or even high-quality products does not make a plan legal. If the compensation structure still rewards recruitment over genuine sales to end users, it can be an unlawful pyramid regardless of product quality.

How does Herbalife's post-2016 structure address this?

The 2016 FTC consent order required Herbalife to categorize members, tie at least two-thirds of rewards to verified retail sales, and ensure 80% of net U.S. sales reach real buyers, under seven years of independent auditing. These are company-specific settlement terms, not the general legal test.

How can someone evaluate an MLM opportunity themselves?

Check whether you can earn without recruiting, whether you are pushed to buy inventory to advance, whether unsold products can be returned, and what the company's published income disclosure shows about typical earnings. Those factors mirror what regulators examine.
