If you have ever received a postcard or email saying "you may be entitled to a payment from a class action settlement," you have already encountered the strange economics of class action distribution. The settlement notice describes a fund of millions, even billions, of dollars — but the per-class-member check often arrives months later for $4.73, $18.40, or sometimes $2,000+, depending on the case. The difference between those numbers is determined by a court-approved plan of allocation, attorney's fees, claim rates, and administration costs. This guide explains exactly how a class action fund moves from defendant to class member, walks through the math used in real settlements, and shows how to estimate your share when you receive a notice.
A class action settlement is funded by the defendant paying a "common fund" (or, less commonly, providing equitable relief). The fund is reduced before any class member sees a check. The waterfall is approximately:
| Structure | Use Case | Formula |
|---|---|---|
| Pure pro rata | Securities, antitrust | Net fund × (claimant's recognized loss / total recognized loss) |
| Flat per-claimant | Consumer, small-damage | Net fund / total valid claimants |
| Tiered by injury | Product liability, mass tort overlap | Tier A: $X, Tier B: 0.6×$X, Tier C: 0.3×$X |
| Claims-made cap | Defendant-favored, low-claim rate | Min(per-claimant cap × claimants, total fund cap) |
| Reversionary | Disfavored by courts post-2017 | Unclaimed funds return to defendant |
Securities cases use the most sophisticated allocation. A "recognized loss" formula assigns each class member a hypothetical damage value based on when they bought and when they sold the security relative to disclosure dates. The formula is filed with the court and explained in the settlement notice.
A typical securities recognized-loss formula:
In a $400 million securities fund with $1 billion in aggregate recognized losses, a class member with $1,000 in recognized loss would receive approximately $400, before deductions for administrator processing.
Antitrust class actions (price-fixing, monopolization) typically use a pro rata formula based on the dollar value of class member purchases during the class period. Federal antitrust law trebles damages (15 U.S.C. § 15), so the fund itself reflects post-treble negotiation but is allocated single-damage style.
Consumer cases — false advertising, breach of warranty, data breach, robocall — typically have small per-member damages ($10-$200) and large class sizes (millions of members). The economic problem is that mailing every class member would consume the entire fund. Resolution typically combines:
The Federal Trade Commission published a study in 2019 finding median claim rates in consumer cases of about 9%, with many cases below 1%. A $50 million fund with a 5% claim rate distributes $50M / (5% × class size). If the class has 10 million members, 500,000 claim; per claimant gets about $80 net of admin fees.
| Method | Calculation | Typical Use |
|---|---|---|
| Percentage-of-fund | X% of gross common fund | Securities, antitrust, consumer mega-cases |
| Lodestar | Hours × hourly rate × multiplier (1.0-4.0) | Fee-shifting statute cases, smaller funds |
| Lodestar cross-check | POF result divided by lodestar to confirm reasonableness | Required by many courts as sanity check |
Empirical studies show median percentage-of-fund awards on a sliding scale:
Facts: $250 million securities settlement, 100,000 valid claims, aggregate recognized losses across all claimants of $750 million.
Facts: $30 million consumer settlement for a mislabeled product. Class size: 6 million purchasers. Claim rate: 4%. Per-claimant cap: $25.
When per-class-member distribution is impractical (claimants are unknown, per-share is below a few dollars), the residual fund is sometimes directed entirely to cy pres recipients. The Supreme Court in Frank v. Gaos, 139 S. Ct. 1041 (2019) signaled but did not finally decide that cy pres-only settlements may not adequately compensate class members. Lower courts have responded by:
The Eleventh Circuit in Johnson v. NPAS Solutions, LLC, 975 F.3d 1244 (11th Cir. 2020) held that incentive awards to named plaintiffs are forbidden by older Supreme Court precedent (Trustees v. Greenough, 105 U.S. 527 (1881)). The 11th Circuit position is in conflict with other circuits and has caused settlements in Alabama, Florida, and Georgia to adopt creative work-arounds. The Supreme Court has declined to resolve the split as of 2026.
| Stage | Typical Duration |
|---|---|
| Preliminary approval order | Day 0 |
| Notice mailing/publication | 30-60 days |
| Objection/opt-out period | 60-90 days |
| Claim deadline | 90-120 days post-notice |
| Final approval hearing | 120-180 days after preliminary |
| Appeal window expiration | 30 days (sometimes 60) |
| Administrator distribution | 60-180 days post-effective date |
| Total typical | 12-24 months |
When you receive a class action settlement notice:
Most notice packets now include a worked example with hypothetical class members to illustrate the calculation.
Most class action settlements follow a court-approved plan of allocation. The total fund is reduced by attorney's fees (typically 25-33%), litigation costs, settlement administrator fees, notice costs, and named-plaintiff incentive awards. The net fund is then divided pro rata using a recognized-loss formula or per-claimant basis among class members who submit valid claim forms.
The plan of allocation is the formula that decides how the net settlement fund is divided among class members. It must be approved by the court as fair, reasonable, and adequate under Federal Rule of Civil Procedure 23(e)(2). Common formulas include pro rata by recognized loss, flat per-claimant payment, or tiered distribution based on injury severity or transaction value.
Class action attorney's fees are typically 25-33% of the common fund, evaluated by the court under either the percentage-of-fund or lodestar method. Courts use a sliding scale: smaller funds get 33%+; mega-funds ($500M+) often get 15-20%. Lodestar (hours × hourly rate × multiplier) is the cross-check.
In a claims-made settlement the defendant agrees to pay only what is actually claimed by class members (subject to a stated maximum or reversion). Unclaimed funds revert to the defendant. Critics argue this incentivizes the defense to suppress notice and complicate claim forms; courts increasingly require non-reversion structures or cy pres distribution.
Cy pres (French: 'as close as possible') directs residual settlement funds to charitable organizations or causes related to the class's interests when full distribution to class members is impractical. The Supreme Court in Frank v. Gaos (2019) signaled skepticism about cy pres-only settlements without ever finally deciding the issue.
Claim rates vary widely by case type. Securities cases typically see 25-50% claim rates among institutional class members. Consumer cases with small per-member values often see 1-5% claim rates. Wage-and-hour and employment cases see higher rates (40-80%) when employees are directly noticed.
Named plaintiffs (class representatives) often receive 'service awards' or 'incentive payments' from the settlement fund — typically $2,500-$25,000 — to compensate for time invested in the litigation. The Eleventh Circuit's 2020 Johnson v. NPAS decision struck these awards as unauthorized, creating a split with other circuits.
From preliminary approval to first distribution: typically 12-24 months. Preliminary approval, notice period (60-90 days), final approval hearing (90-180 days after notice), appeal period (30-60 days), administrator processing (60-180 days). Complex cases or appeals can extend this to 3-5 years.
