How Much Does a Bias Audit Cost in NYC?

Three Quotes, Three Different Numbers, No Line Item to Compare

You send the same request to three independent auditors: "We need an annual bias audit for our resume-screening tool under Local Law 144. What does that cost?" Two weeks later you have three replies. None of them contain a number you can hold up against the other two. One wants a call to scope it. One asks how many AEDTs you run and whether you have two years of applicant data by race, ethnicity, and sex already assembled. One just says "custom, depends on engagement."

This is normal, and it's not a stall tactic. Every LL144 bias audit is a bespoke statistical engagement, not a subscription line item, and the auditors who quote fast without asking questions are usually the ones who haven't looked closely at your data yet. But "normal" doesn't help you build a budget line or defend a number to your CFO.

This article breaks down what actually drives a bias audit quote in NYC, what the named market players signal about pricing structure (without inventing a number none of them publish), and how to walk into the RFP process with enough scoping detail that the quotes you get back are actually comparable. By the end, you'll know what to ask before you accept any number.

Why Nobody Publishes a Price for a Bias Audit in NYC

Search for "bias audit cost" and you won't find a rate card anywhere, because there isn't one. Local Law 144 requires that the audit be conducted by an independent auditor — someone with no financial or employment relationship to your company or to the AEDT vendor whose tool you're auditing. That independence requirement pushes the market toward engagement-based statistical work: an auditor has to design a test appropriate to your specific tool, your specific hiring data, and your specific selection outcomes, then calculate impact ratios against the four-fifths rule the EEOC's Uniform Guidelines describe — the rule of thumb that a group's selection rate below 80% of the highest-selected group may signal adverse impact (Assessment Systems, 2024). That's custom analytical work, not a checkbox service.

So when you ask "how much does a bias audit cost NYC employers," the honest answer is: it depends on what's being audited, and no auditor will quote you before understanding that. Treat any flat number offered without a scoping conversation with suspicion.

What Actually Drives the Price

Every auditor scopes differently, but the levers that move a quote up or down are consistent across the market:

Number of AEDTs in scope. If you run one resume-screening tool, that's one statistical test design. If you run a screening tool, a video-interview scoring tool, and a ranking algorithm, that's three separate analyses — three sets of impact-ratio calculations, three audit reports, and likely three summaries for your public disclosure page.

Data readiness. LL144's own reporting logic runs on historical selection data broken out by race/ethnicity/sex categories. If you already have two years of clean applicant-flow data organized by category, the auditor's job is mostly analysis. If that data is scattered across an ATS export, a spreadsheet HR built by hand, and institutional memory, the auditor's job includes a data-cleanup phase before the statistics even start — and that phase costs time.

Initial audit vs. renewal. The first audit of a given tool typically requires more setup: understanding the tool's scoring logic, agreeing on what counts as a "selection" event, and building the test methodology from scratch. A renewal on a tool the auditor already audited last year is faster, because the methodology exists.

Assurance standard used. Some auditors work under formal assurance frameworks. BABL AI, for example, conducts LL144 engagements under the ISAE 3000 assurance standard (BABL AI, 2025) — a recognized international framework for assurance engagements. Work performed to a named assurance standard generally carries more rigor, and more cost, than an ad hoc statistical review.

Company and hiring-volume size. A 60-person employer with 400 annual applicants is a smaller statistical population than a 250-person employer running thousands of candidates a year through the same tool. Larger populations don't always mean proportionally larger cost, but they change the analysis.

None of these levers has a public number attached anywhere in the market, and this article isn't going to invent one. What you can do is control how much of that scoping work is already done before an auditor ever prices your engagement — which is the part actually in your hands.

What the Named Market Signals — Without a Price Tag

It's worth knowing who's who before you send an RFP, because the vendors circling this space aren't all offering the same thing.

Warden AI positions itself as a continuous, independent bias-auditing platform for HR-tech vendors and employers, and markets across LL144 alongside the EU AI Act and Illinois HB 3773. Framework lists on vendor sites age quickly — Colorado's SB 24-205 was repealed and replaced on 14 May 2026 by SB 26-189, the Automated Decision-Making Technology Act — a narrower disclosure regime that drops the impact-assessment and duty-of-care requirements and takes effect 1 January 2027. It sits on the audit-execution side of the market — it is an independent auditor — and its pricing is flat-fee, structured around the annual audit cycle, but not publicly listed.

BABL AI is an independent third-party auditor performing LL144 engagements under the ISAE 3000 standard, also audit-execution side, engagement-quoted rather than listed.

FairNow (now part of AuditBoard) and Holistic AI are general-purpose AI-governance platforms aligned to frameworks like ISO 42001 and NIST AI RMF. They aren't NY-statute-specific tools, and neither publishes a public price.

VerifyWise is a source-available GRC tool covering LL144 among many frameworks, with a free self-hosted starting point that requires technical setup, plus custom enterprise deployment for larger organizations.

None of these five will hand you a number without a scoping call, and none of their prices belong in a public article — every one of them is custom or unlisted. What matters for your RFP is the structural line running through this list: an auditor cannot also sell you the documentation tooling you use to prepare for that same audit, because LL144 requires the auditor to have no financial or employment relationship with you or your AEDT vendor. That's a conflict-of-interest rule, not a sales pitch. It's the reason a documentation and readiness product — the kind of thing WorkforceNewYork builds — sits on a different side of the fence than the auditor you're paying for the statistical work itself.

Getting a Fair Quote Starts With Scoping It Yourself First

The single biggest thing you control in this process is showing up to the RFP with your scope already defined, instead of asking an auditor to define it for you on their clock. Before you send a single request, you should be able to answer:

• How many distinct AEDTs are in scope, and what does each one output (a score, a rank, a classification)?
• Is this an initial audit or a renewal of a tool audited last year?
• Do you have two years of applicant-flow data broken out by race/ethnicity/sex, or does that need to be assembled first?
• What's your realistic applicant volume over the audit period?

Auditors who get clean answers to these questions upfront can quote faster and — because they aren't pricing in unknown discovery risk — often quote tighter. Auditors who get vague answers price in the uncertainty, because they have to.

A quote built on a scoping conversation with a well-prepared client and a quote built on "we're not sure yet" are not the same market rate — they're two different jobs wearing the same label.

This is where the Independent-Auditor Engagement RFP & Scoping Kit earns its place as the first thing you open before you send a single RFP. It's a documentation and worksheet kit — a scoping questionnaire, a data-readiness checklist, and an RFP template built to get apples-to-apples quotes back from multiple auditors. It doesn't perform, certify, or sign your bias audit; that's the auditor's job, and it has to stay that way under LL144's independence rule. What the kit does is make sure the quote you get reflects your actual scope, not an auditor's best guess about it.

Documentation Kit or Independent Auditor: Know Which One You're Buying

A recurring confusion in this market is between platforms that audit and tools that document. Our breakdown of bias-audit platforms vs. independent auditors covers that distinction in depth, but the short version matters here too: WorkforceNewYork's workbooks track your vendor's audit status, help you organize the data an auditor will need, and document the rationale behind your compliance decisions — the "here's why we made this call" file you can defend later. They never perform the statistical bias test, never certify a result, and never score an individual candidate. That work belongs to an independent auditor, full stop, and this article is operational guidance on budgeting for that engagement, not legal advice — for anything specific to your company's exposure or a filing deadline, confirm the details with DCWP or with outside counsel.

If you're still early in understanding the law itself — who counts as covered, what "AEDT" actually means, what the notice and posting requirements are — start with our Local Law 144 compliance guide and our overview of what an independent auditor does under LL144 before you request a single quote. Getting the mechanics straight first is what makes the RFP conversation short instead of circular.
