Run the Numbers

Model a consumer mass arbitration campaign end to end — claimant acquisition, screening, the AAA filing spike, the monthly carry, and resolution. Every slider is a barrier to entry made tangible.

This simulator is an educational illustration of publicly reported cost structures in consumer mass arbitration. It is not legal, financial, or investment advice; it is not a solicitation or an inducement to bring claims; and it materially simplifies real campaigns. Fee schedules change — verify current AAA/JAMS schedules before relying on any figure. Outcomes shown are hypothetical.

Practice areaPresets set defaults — every slider stays yours to drag.

For reference: injury mass torts run $2,550–$9,950 per signed case with 20–30% attrition — arbitration campaigns are a different acquisition business.1

Median and P10/P90 include dismissal runs — the bars are split so the settled distribution's shape stays readable, but the headline stats score the whole mixture.

The other side of the caption

At 300 filed demands, the respondent's AAA bill — before defense counsel or arbitrator time at $300/hr — is the leverage number:

Respondent pays	Amount
Initiation fee	$8,125
Per-case fees (tiered, net of credit)	$89,375
Arbitrator appointment (10% of cases)	$13,500
Claimant-side fees absorbed too	$39,000
Total at filing — both sides	$150,000

With the respondent responsible for filing fees, it absorbs both sides of the schedule while your side pays $0 — the asymmetry, doubled.2
