How much are mass arbitration fees? AAA costs at 100, 500 and 1,000 cases, and how JAMS differs
What AAA consumer mass arbitration fees add up to at 100, 500 and 1,000 cases for claimants and businesses, how JAMS differs, and what courts say about nonpayment.
Mass arbitration fees at the AAA fall mostly on the business: claimants in a consumer mass arbitration pay a flat $3,125 to file and no more than $200 per case if cases reach the merits, while the business pays $8,125 to start, $325 per case to the claimants' $125 for the first 500 cases that go forward, and all arbitrator compensation. If every case reaches a hearing date, the business's AAA fees run about eight times the claimants' per case. JAMS bills mass filings under a separate fee schedule, and where it applies its Consumer Minimum Standards, the only fee required of the consumer is $250.
- The AAA's mass rules start at 25 similar consumer or employment demands. JAMS's start at 75 and apply only if the parties agreed to them in writing.
- At the AAA, 1,000 cases that all reach a hearing date would cost claimants $150,000 to $175,000 in AAA fees and the business $1.34 million to $1.49 million, before arbitrator compensation, which the business pays.
- Most cases stop well short of that. Of 6,360 merits-stage consumer cases the AAA closed in 2025, 72% settled, and 96% of those settled before a merits arbitrator was appointed.
- Recent appeals courts have declined to order businesses to pay provider fees, and the First Circuit held that Amex waived its right to compel arbitration by refusing to pay after repeated warnings.
When do mass arbitration rules apply at AAA and JAMS?
The AAA's Mass Arbitration Supplementary Rules (arbitration costs amended and effective January 15, 2024) cover 25 or more similar consumer or employment demands against the same or related parties, where representation is "consistent or coordinated across the cases" (MA-1(b)). Filings in waves still count: the rules apply "whether or not such cases are filed simultaneously" (MA-1(c)). The AAA decides whether they apply, subject to review by a Process Arbitrator (MA-1(a)).
JAMS's Mass Arbitration Procedures and Guidelines (effective May 1, 2024) set the bar at 75 similar demands, or another number set by the parties' agreement, from claimants represented by the same or coordinating firms (Procedure 1(c)). And they apply only if the parties agreed to them in a written agreement, before or after the dispute (Procedure 1(a)). That makes the arbitration agreement the first document to pull.
What does the AAA charge at each stage of a consumer mass arbitration?
The AAA's Consumer Mass Arbitration and Mediation Fee Schedule (amended and effective January 15, 2024) bills by stage. The claimants' initiation and per case amounts below match what the AAA restated in its June 3, 2026 mass arbitration data release.
- Initiation fee. Claimants pay a flat $3,125 "upon the filing of a mass arbitration." The business pays a flat $8,125 once claimants meet the filing requirements. It covers the AAA's administrative review, a conference call and appointment of a Process Arbitrator or Global Mediator, and stays due if cases settle or are withdrawn.
- Per case fees. Charged only for cases that "proceed with administration beyond the Initiation stage." Claimants pay $125 per case for the first 500 and $75 after that. The business pays $325 for the first 500, $250 for cases 501 to 1,500, $175 for cases 1,501 to 3,000 and $100 after that. The initiation fee is credited toward these.
- Arbitrator appointment fee. Billed before merits arbitrators are appointed: $50 per case for claimants and $450 for the business with direct appointment, or $75 and $600 with list-and-rank selection.
- Final fee. $600 per case for the business, billed when a hearing is scheduled or a documents-only case gets its final submission date.
- Neutrals. Merits arbitrators are paid $300 per hour; the Process Arbitrator and mediator at the rates on their AAA resumes. The business pays all three unless an individual, after the dispute arises, chooses to pay a share.
- Abeyance. $2,500 every six months that cases are held in abeyance, paid by the business.
The AAA's June 2026 release adds: "Total fees per consumer who do not qualify for a waiver are not more than $200 per case." The schedule also notes fee waivers for lower-income consumers in California and New Jersey. The AAA's current version of the schedule, now titled "Costs of Arbitration and Mediation," keeps these arbitration fees; only its mediation costs changed, effective June 1, 2026.
What do mass arbitration fees add up to at 100, 500 and 1,000 cases?
We ran the AAA's consumer mass schedule at three volumes, assuming every case passes initiation, gets a merits arbitrator and reaches a hearing date or documents-only deadline. Figures use direct appointment, with list-and-rank in parentheses, and cover AAA fees only (no arbitrator hours, expenses or abeyance fees).
| AAA fees, all cases to a hearing date | 100 cases | 500 cases | 1,000 cases |
|---|---|---|---|
| Claimants: per case fees (initiation fee credited) | $12,500 | $62,500 | $100,000 |
| Claimants: appointment fees | $5,000 ($7,500) | $25,000 ($37,500) | $50,000 ($75,000) |
| Claimants: total | $17,500 ($20,000) | $87,500 ($100,000) | $150,000 ($175,000) |
| Claimants: per case | $175 ($200) | $175 ($200) | $150 ($175) |
| Business: per case fees (initiation fee credited) | $32,500 | $162,500 | $287,500 |
| Business: appointment fees | $45,000 ($60,000) | $225,000 ($300,000) | $450,000 ($600,000) |

Two caveats. Many consumer arbitration clauses shift the consumer's share of fees to the business. And the AAA "reserves the right to determine what tier of fees applies to cases filed subsequent to the initial filing," so later waves may not stack into lower tiers.
If every case settles at initiation, AAA fees are flat at any volume: $3,125 for the claimants and $8,125 for the business, plus any Process Arbitrator or mediator time the business pays.
The full-hearing column is a ceiling. The AAA's 2025 data release (June 3, 2026) shows how consumer mass cases at the merits stage actually closed:
| AAA consumer mass arbitration, 2025 | Figure |
|---|---|
| New consumer demands filed | 104,556 |
| Merits-stage consumer cases closed | 6,360 |
| Share of those settled | 72% |
| Settlements reached before a merits arbitrator was appointed | 96% |
| Merits-stage consumer cases decided by award | less than 1% |
| Closed merits cases where consumers paid $0 | 17% |
A worked example: 500 consumer cases pass initiation and settle before the appointment fee is billed. Under the schedule, the claimants would have paid $62,500 in AAA fees and the business $162,500.
How does JAMS handle fees in a mass arbitration?
At JAMS, the parties pay "JAMS' initial filing fee as set forth in the JAMS Mass Arbitration Fee Schedule" (Procedure 7(a)). The Process Administrator and arbitrators are paid under JAMS's General Fee Schedule (Procedures 7(c) and 7(d)). If JAMS determines its Consumer Minimum Standards apply, fees are "allocated consistent with those Minimum Standards," subject to the Process Administrator's review (Procedure 7(b)).
The JAMS Consumer Minimum Standards (effective May 1, 2024) say "the only fee required to be paid by the consumer is $250" and "All other costs must be borne by the company," including the case management fee and all professional fees (Standard No. 7). JAMS's standard arbitration fee schedule, which governs ordinary filings rather than mass filings, applies the same $250 consumer share to a $2,500 two-party filing fee.
The dollar amounts for mass filings sit in JAMS's separate Mass Arbitration Fee Schedule, linked from the procedures page. Check the current version there before budgeting a JAMS filing.
Process differs too. JAMS says "JAMS does not include either mandatory mediation or test cases in these Procedures," while the AAA has the parties start a global mediation within 120 days of the answer due date, with a unilateral opt-out (MA-9).
What do claimant firms have to file and certify at each provider?
Both providers moved verification to the front of the case. The rule text, side by side:
| Topic | AAA Mass Arbitration Supplementary Rules (Apr. 1, 2024) | JAMS Mass Arbitration Procedures (May 1, 2024) unless noted |
|---|---|---|
| Threshold | "twenty-five or more Consumer or Employment/Workplace similar Demands for Arbitration" (MA-1(b)(i)) | "75 or more similar Demands for Arbitration, or such other amount as is specified in the Parties' agreement(s)" (Proc. 1(c)) |
| When the rules apply | "The AAA-ICDR may apply these Supplementary Rules to any group of cases defined as a Mass Arbitration" (MA-1(a)) | When "the Parties have agreed to the application of these Mass Arbitration Procedures and Guidelines" (Proc. 1(a)) |
| Demands | "A separate Demand for Arbitration must be filed in each individual case." (MA-2) | "A Demand for Arbitration Form and applicable arbitration agreement must be submitted for each Claimant." (Proc. 2(a)) |
| Claimant data | A "Mass Arbitration Intake Data Spreadsheet" at the threshold, updated "as additional cases are filed" and served on the other side (MA-2) | "Each Demand must include the first and last name, physical address and email address of the Claimant, as well as representative information." (Proc. 2(b)) |
| Counsel's certification | "an affirmation that the information provided for each individual case is true and correct to the best of the representative's knowledge" (MA-2) | "a sworn declaration from counsel averring that the information in the Demand is true and correct to the best of the representative's knowledge" (Proc. 2(c)) |
| Early gatekeeper | A Process Arbitrator decides issues including "Whether the parties have met the AAA-ICDR's filing requirements" (MA-6(c)(i)) | A Process Administrator decides issues including "Whether the Parties have met the filing requirements of these Procedures" (Proc. 3(e)(i)) |
What happens if the business doesn't pay the fees?
The AAA "may notify the parties in order that one party may advance the required payment" (MA-10(d)), may suspend or terminate cases before an arbitrator is appointed, and "may also decline to administer future arbitrations with the parties involved" (MA-10(e)). JAMS's fee schedule says that if a company fails to pay in a consumer case, "JAMS may place the matter on administrative suspension" so the consumer "may seek appropriate redress in a court of competent jurisdiction."
Recent appeals decisions:
- Wallrich v. Samsung Electronics America, Inc., 106 F.4th 609 (7th Cir. July 1, 2024). Reversed orders compelling Samsung to arbitrate with 35,651 consumers and to pay AAA filing fees. The consumers had not proved they had arbitration agreements; a spreadsheet of names and addresses and the AAA's filing determination were not enough. Even if they had, the district court "exceeded its authority and the scope of the arbitration agreement" by ordering payment.
- Frazier v. X Corp., 155 F.4th 87 (2d Cir. Sept. 2, 2025). Reversed an order compelling X to pay JAMS fees in former employees' arbitrations, holding that refusing to pay "does not amount to a 'failure, neglect, or refusal . . . to arbitrate'" under the Federal Arbitration Act.
- 5-Star General Store v. American Express Co., No. 25-1023 (1st Cir. Aug. 19, 2026). Small merchants filed 5,155 antitrust arbitrations under the AAA's Commercial Rules. Amex disputed the $3,500 per case filing fee and didn't pay its $3,150 share despite repeated warnings, and the AAA closed the cases. The court found "Amex's conduct was inconsistent with an intent to arbitrate" and affirmed denial of its motion to compel.
None of these courts ordered a business to pay a provider's fees, and the First Circuit held that Amex, having refused to pay after repeated warnings, waived its right to compel arbitration. Each decision turned on its own agreement and record, and the law differs by circuit and by state.
California adds a statute. Under Code of Civil Procedure section 1281.97, invoices are "due upon receipt" unless the agreement sets a deadline, and if the fees to start an employment or consumer arbitration are "not paid within 30 days after the due date the drafting party is in material breach of the arbitration agreement." Section 1281.98 does the same for fees during the arbitration. In Hohenshelt v. Superior Court, 18 Cal.5th 310 (Aug. 11, 2025), the California Supreme Court held section 1281.98 "is not preempted by the FAA" and read it so that late payment forfeits arbitration only when the nonpayment was "willful, grossly negligent, or fraudulent." A late payer can seek relief if the delay was excusable.
What this means for your firm
- Budget by stage, not by filing count. At the AAA, the claimant-side cost at filing is flat. The variable cost arrives when cases pass initiation and again at arbitrator appointment, so model cash on how many cases you expect to reach each stage.
- Treat intake data as filing data. The AAA spreadsheet and affirmation and the JAMS per-demand declaration are built from intake records: names, physical addresses, emails and each claimant's agreement. Wallrich shows how much can turn on proving each claimant's agreement, and duplicates or missing addresses are the kind of filing issue a Process Arbitrator or Process Administrator rules on.
- Provider notices carry weight. In each nonpayment case above, the provider's invoices, warnings and closure letters were central to the court's analysis.

FAQ
No. The AAA describes it as "a flat fee of $3,125 regardless of how many cases are filed." The business pays its own flat $8,125 initiation fee once the filing requirements are met. For cases that move past initiation, both fees are credited toward per case fees, so they work like a nonrefundable prepayment on the next stage.
Sometimes. The AAA's consumer mass fee schedule notes that California and New Jersey consumers with gross monthly income under 300% of the federal poverty guidelines are entitled to a waiver of arbitration fees and costs, other than arbitrator fees. The AAA reports that consumers paid $0 in 17% of the merits-stage consumer mass cases it closed in 2025, without saying how many of those reflect waivers.
In Wallrich (7th Cir. 2024) and Frazier (2d Cir. 2025), federal appeals courts declined to, treating fee disputes as matters for the provider under the parties' agreement. In California, sections 1281.97 and 1281.98 attach consequences to late payment in employment and consumer arbitrations, with section 1281.98 construed in Hohenshelt (2025). Results depend on the agreement and the jurisdiction.
