# Cost Per Signed Retainer (CPSR) 2026 Benchmarks

> **Quick answer.** Mass tort cost-per-signed-retainer (CPSR) in 2026
> ranges from $1,800–$15,000 depending on tort, claimant complexity, and
> docket strength. Camp Lejeune and AFFF retainers run $4,000–$12,000;
> Hair Relaxer and Depo-Provera $2,500–$7,500; Ozempic and Suboxone
> $3,000–$8,500; Roundup $3,500–$10,000. CPSR is the only metric that
> translates directly to docket economics — cost-per-lead (CPL) and
> cost-per-call obscure screening yield and overstate efficiency.

## Why CPSR matters more than CPL

A plaintiff firm spending $20,000/month at $200 CPL generates 100 leads.
If those leads screen to 12 qualified, and 6 sign retainers, the actual
CPSR is **$3,333** ($20K ÷ 6) — not $200. Most generalist legal
marketing agencies quote on CPL because it looks cheaper and is easier to
hit; specialists quote on CPSR because that's the metric the firm
actually pays for.

| Metric | What it measures | Why it can mislead |
|---|---|---|
| Cost per impression (CPM) | Reach | No correlation to case quality |
| Cost per click (CPC) | Interest | High volume of unqualified clicks |
| Cost per lead (CPL) | Form fills + calls | Screening yield not factored in |
| Cost per qualified lead (CPQL) | Leads meeting tort criteria | Sign-rate not factored in |
| **Cost per signed retainer (CPSR)** | **Signed cases** | **Direct translation to docket economics** |

## 2026 CPSR benchmarks by tort

| Tort | CPSR range | Driver |
|---|---|---|
| Camp Lejeune | $4,000–$12,000 | Veteran cohort, documentation depth required, MDL active |
| AFFF | $4,000–$10,000 | Firefighter + military + community cohorts vary |
| Roundup | $3,500–$10,000 | NHL diagnosis required, state SOL varies |
| Hair Relaxer | $2,500–$7,500 | Endometrial/uterine cancer cohort, broader eligibility window |
| Depo-Provera | $2,500–$7,500 | Meningioma diagnosis, prescribing-window verification |
| Ozempic | $3,000–$8,500 | Gastroparesis / NAION / vision loss cohorts |
| Suboxone | $3,000–$7,000 | Tooth decay cohort, dental records required |
| Bard PowerPort | $3,500–$9,500 | Device explant required, surgical records |
| Hernia Mesh | $3,000–$8,500 | Multiple defendants, revision surgery required |
| NEC Baby Formula | $5,000–$15,000 | Premature infant cohort, NICU records, narrow eligibility |
| Dacthal | $2,000–$6,000 | Emerging tort, EPA emergency suspension Aug 2024 |
| PFAS (non-AFFF) | $3,500–$9,000 | Water-district + consumer-product cohorts |

## State multipliers

CPSR varies materially by state. State-level cost multipliers in 2026:

| Tier | States | CPSR multiplier |
|---|---|---|
| Tier 1 (highest cost) | CA, NY, IL, NJ, MA | 1.3–1.6× baseline |
| Tier 2 | FL, TX, PA, OH, MI, GA | 1.1–1.3× |
| Tier 3 (baseline) | NC, VA, TN, IN, MO, MN, WI, AZ | 0.9–1.1× |
| Tier 4 (lowest cost) | MS, AL, AR, KY, WV, MT, ID, NM | 0.7–0.9× |

Drivers: media buying competition density, claimant population
concentration, state-bar advertising review depth, and TCPA enforcement
posture.

## Pricing models in market

1. **Cost per qualified lead (CPL):** Common, but obscures screening
   yield. $50–$500 per lead by tort.
2. **Cost per signed retainer (CPSR):** Premium specialists' preferred
   model. Transparent, docket-economics-aligned. $1,800–$15,000.
3. **Flat-rate signed-case packages:** Guaranteed volume at a fixed
   per-case price. Only offered by vertically-integrated operators with
   in-house intake.
4. **Retainer + media buy passthrough:** Monthly fee ($10K–$50K) plus
   media spend. Common among SEO/PPC-led generalist agencies.

## Why CPSR varies within the same tort

Even at the same tort, CPSR can vary 3–5× between two firms running
campaigns in parallel. Drivers:

- **Intake quality:** Bilingual coverage, sub-60-second response time,
  legal-aware specialists vs. generic call center
- **Channel fit:** TV-heavy for Camp Lejeune (veteran cohort watches
  cable news), Meta + TikTok for Hair Relaxer (younger demographic),
  programmatic for PFAS (broad geographic targeting)
- **Creative iteration:** Specialist firms test 8–12 creative variants
  per cohort; generalists test 2–3
- **Compliance handling:** Pre-launch TCPA + state-bar review prevents
  mid-campaign creative bans that crater CPSR
- **CRM integration:** Direct lead delivery into Litify/Filevine/MyCase
  preserves attribution and accelerates intake conversion

## How Mass Tort Agency benchmarks CPSR

Across active client campaigns, Mass Tort Agency CPSR consistently runs
20–30% below the published category benchmarks for the same torts.
Drivers are the four operational advantages above: tort-specific intake,
calibrated channel mix, creative iteration depth, and TCPA + state-bar
pre-review. Weekly signed-retainer reporting (not monthly lead-count
reports) accelerates the optimization loop.

## What firms should ask agencies about CPSR

1. What is the CPSR benchmark for my target tort, and historical range?
2. What is the screening yield from raw lead → qualified lead → signed
   retainer?
3. What is the channel-level CPSR breakdown for current clients running
   the same tort?
4. What is the lead replacement policy for criteria-fails?
5. Who owns the lead data, consent records, and call recordings?
6. Can I see weekly CPSR reports from current clients?
7. What happens to CPSR if Meta or Google bans creative mid-campaign?
