How to calculate Treble Damages in United States Federal

US treble damages rules

This source-backed guide covers US federal treble damages authority (15 U.S.C. § 15 — antitrust treble damages). It explains how to read the calculator's multiplier output and points to the controlling US multiplier statutes.

What the output means

Run this scenario in DocketMath using the Treble Damages calculator.

When the calculator shows a multiplier result, read it as a statutory multiplier on the base damages figure, not as a separate damages category.

• Base damages stay the same until the multiplier is applied.
• The statutory multiplier changes the total by the rule-specified factor.
• Any cap, exception, or carve-out still controls if the statute says it does.

US rule notes

Antitrust Treble Damages — 15 U.S.C. § 15(a)

Any person injured in business or property by antitrust violations shall recover threefold the damages sustained plus costs and attorney's fee.

15 U.S.C. § 15. Any person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws may sue therefor in any district court of the United States in the district in which the defendant resides or is found or has an agent, without respect to the amount in controversy, and shall recover threefold the damages by him sustained, and the cost of suit, including a reasonable attorney's fee.

What changes the result most

• The base damages input, because the multiplier applies to that number.
• The statutory multiplier itself, because 2x, 3x, and 4x produce different totals.
• Any cap or carve-out in the statute, because it can limit the multiplied amount.

Use the calculator

DocketMath's treble-damages calculator can model multiplier outcomes once you identify the controlling statute and whether a cap or exception applies. Use the source panel for the verified primary-source rule.
