EU Digital Laws: Billions in Fines Explained

The European Union’s Digital Markets Act (DMA) and Digital Services Act (DSA) can impose fines of up to 10% of a company’s global annual turnover, and for repeated infringements, up to 20%. For the largest tech firms, whose revenues exceed $100 billion, that translates into potential fines of over $10 billion per violation.

Formula

The maximum fine is calculated as:

Fine = Annual Global Turnover × Fine Rate

• Annual Global Turnover – the company’s total worldwide revenue in the preceding financial year, in euros.
• Fine Rate – the percentage applied by the regulator. Under the DMA and DSA, this is 10% for a first violation, and 20% for a repeat violation.

Worked Example

Using the default values: a company with €100 billion in global revenue faces a first-offense fine at 10%.

1. Convert the revenue to euros: €100,000,000,000
2. Apply the fine rate: 10% of €100,000,000,000 = €10,000,000,000
3. The maximum fine is €10 billion.

That matches the calculator’s output of 10,000,000,000 EUR.

Background: What Are the DMA and DSA?

The Digital Markets Act (DMA) and Digital Services Act (DSA) are two landmark EU regulations that came into force in 2022 and 2023. They target large online platforms—often called “gatekeepers” or “Very Large Online Platforms”—to ensure fair competition and user safety. The DMA focuses on economic fairness (e.g., preventing self-preferencing, allowing third-party app stores), while the DSA focuses on content moderation, transparency, and user rights.

Both laws apply to companies with significant reach in the EU: the DMA for platforms with over 45 million monthly active users and €7.5 billion in turnover; the DSA for platforms with over 45 million users. This includes major tech companies like Alphabet, Amazon, Apple, Meta, and Microsoft.

How Fines Are Calculated and Imposed

The maximum fine is 10% of the company’s total worldwide annual turnover—not just EU revenue. For repeat offenders, the cap rises to 20%. In addition, the EU can impose periodic penalty payments of up to 5% of average daily turnover for non-compliance during an investigation.

The European Commission is the enforcement body. It can launch investigations on its own or based on complaints. The fine amount depends on the severity, duration, and deterrence effect. The Commission also considers mitigating factors like cooperation and remedies offered.

For example, if a company with €200 billion in global revenue violates the DMA, the maximum fine is €20 billion. Even a 1% fine would be €2 billion.

What the Fines Mean for Big Tech

For the largest tech companies, a 10% fine is substantial but not crippling. Alphabet’s 2023 revenue was over $300 billion, so a maximum DMA fine could exceed $30 billion—more than many countries’ GDP, but still a fraction of their cash reserves. The real impact is reputational and regulatory: fines signal that the EU is serious about enforcement, and companies may need to change business models to comply.

Smaller companies that qualify as gatekeepers face fines that could be more painful relative to their size. Yet the EU designed the thresholds to target only the largest players, so most businesses are unaffected.

Common Misconceptions and Mistakes

One common misconception is that the 10% fine applies to EU revenue only. In fact, it applies to global turnover. Another is that fines are automatic—they are not. The Commission must conduct a full investigation and issue a formal decision.

People also confuse the DMA and DSA. The DMA is about competition and market fairness; the DSA is about illegal content, disinformation, and user safety. A company can be fined under both for different violations.

Finally, note that the fine is a maximum—the actual amount is often lower. For example, the EU has not yet imposed a fine under the DMA as of 2025, though investigations are ongoing.

How to Use This Calculator

This calculator helps you estimate the potential maximum fine for a company based on its global revenue. Enter the company’s annual turnover in euros and the fine rate (10% for first offense, 20% for repeat). The result is the maximum fine in euros.

To get a realistic estimate, you may want to use a lower rate (e.g., 5%) to see a possible mid-range penalty. You can also compare different companies by changing the revenue input.

Remember that the actual fine depends on many factors, so this is a rough upper bound, not a prediction.

Limitations and Next Steps

This calculator only provides the mathematical maximum. It does not account for:

• Mitigating or aggravating circumstances
• Periodic penalty payments (up to 5% of daily turnover)
• Remedies or behavioral commitments that may reduce fines
• Appeals or settlements

If you want to track actual enforcement, follow the European Commission’s digital strategy pages. As of early 2025, several DMA investigations are underway, but no final fines have been announced. The DSA has already led to formal proceedings against some platforms, but again, no fines have been finalized.

Frequently Asked Questions

Does the 10% fine apply to revenue from Europe only?

No. The fine is based on the company’s total worldwide annual turnover, not just EU revenue. This is to ensure the fine is significant enough to deter even the largest global firms.

Can a company be fined under both the DMA and DSA?

Yes. The two laws cover different areas. A company could face separate fines for a competition violation under the DMA and a content moderation violation under the DSA. The fines are calculated independently.

What happens if a company doesn’t pay the fine?

The European Commission can take the company to the Court of Justice of the EU to enforce payment. The court can also impose additional penalties for non-compliance.

Are there any companies that have already been fined?

As of early 2025, no final fines have been imposed under the DMA. Under the DSA, formal proceedings have been opened against some platforms, but no fines have been announced yet. The EU tends to negotiate compliance before resorting to fines.

How do I find a company’s global annual turnover?

Publicly traded companies report revenue in their annual reports (e.g., 10-K filings in the US). For private companies, you may need to use estimates from financial databases or news reports.
