Expert Witness Fees and Rates

Every published number was produced by a seller

There is no probability-sample survey of what expert witnesses charge in the United States. No bar association publishes one. No peer-reviewed study of expert compensation was located in the research behind this page; the academic literature on expert witnesses addresses use, admissibility and juror perception rather than price.

What exists is a small number of recurring publications, and each is produced by a company that sells into this market. SEAK, Inc. sells expert witness training, conferences, a directory listing service and the fee survey itself. ExpertPages is a listing directory whose experts pay to appear. Expert Institute is an expert search and referral business that charges attorneys for access and placement. None of that makes the figures worthless. It makes them figures about a market, collected from inside it, by parties with an interest in the number being high.

Two further cautions run through everything below. All of these figures except Expert Institute's are self-reported asking rates rather than realized or collected billings — SEAK's own 2021 report records that 28 percent of respondents had experienced a client failing to pay, which is enough to show that asking and receiving are different quantities. And all of them are non-probability samples: no published response rate, no weighting, and in SEAK's case a frame drawn from the publisher's own client list.

The SEAK series, and what its sample is

The largest recurring series is SEAK, Inc.'s Survey of Expert Witness Fees. The 2024 edition, by James J. Mangraviti, Jr., Kelly J. Wilbur and Nadine Nasser Donovan, collected responses in January and February 2024 from more than 1,600 experts — the summary report states 1,633 respondents — across some 250 listed areas of expertise. The summary describes no recruitment frame, no response rate and no weighting; figures are as provided by the responding experts.

The aggregate figures, all hourly and across all disciplines: file review and case preparation, a median of $450 against a mean of $466; deposition testimony, a median of $500 against a mean of $571; trial testimony, a median of $500 against a mean of $633. Reported retainers: a median of $3,000 against a mean of $4,084. The spread is wide, from a low of $55 across all service types to a high of $2,500 for review and deposition and $3,500 for trial testimony. On volume, the reported median for typical total billings per case is $7,000, and the median for the most ever billed on one case is $25,000.

The 2021 edition surveyed nearly 1,100 experts in January 2021 and states expressly that respondents were SEAK clients — that is, a convenience sample of people who had already bought marketing or training from the publisher. Its figures ran lower: file review a median of $400, deposition a median of $475, trial testimony a median of $500. Among respondents who required one at all, the reported median retainer was $2,600. The 2024 summary report is published in full.

ExpertPages, Expert Institute, and why they do not agree

ExpertPages has run an Expert Witness Fees & Practices Survey since 1998. The 2024 edition, published on 20 June 2024, drew more than 500 expert witnesses and litigation consultants across North America, of whom approximately 35 percent were ExpertPages accredited members and 65 percent were not — the only one of these surveys that discloses the split between the publisher's own customers and everyone else. The reported overall average is $451 hourly, against $408 in 2022, $367 in 2019 and $341 in 2017, with a reported range from under $200 to over $1,000. The release notes that most expert work involves reviewing files, preparing analyses and writing reports rather than testifying at trial.

Expert Institute's 2018 Expert Witness Fee Report, by Victoria Negron, is different in kind and the difference matters. Its figures are derived from the company's own completed engagements during 2018 rather than from a survey of experts, with daily rates converted to hourly by dividing by eight. Its national averages: $353.26 for initial case review, $446.78 for a deposition appearance and $461.53 for courtroom testimony. It also reports a wide split by discipline — a combined average of $478.50 for medical experts against $296.12 for non-medical — with surgical specialties at the top of the medical table.

The engagement-derived figures run materially below the survey-derived figures for the same activities. Both cannot describe the same quantity. The defensible reading is that survey figures describe what experts say they charge, and engagement figures describe what one intermediary's clients actually paid.

Read the median, not the average

In the SEAK 2024 data the trial testimony median is $500 and the mean is $633. That gap is not noise. It is a long right tail of very high billers pulling the average up, and it recurs in every activity: review, a median of $450 against a mean of $466; deposition, $500 against $571. The mean describes a distribution containing experts who charge many times the typical figure; the median describes the middle of the market.

The same caution applies to any national figure quoted without its publisher, year, sample and method. An average assembled from a self-selected sample of sellers is not a benchmark against which an individual quote can be judged. It is an order of magnitude, useful mainly as a description of structure: that review, deposition and trial are priced separately, that retainers are normal, that minimums and cancellation terms exist.

Variation by discipline, market and case size dwarfs the gap between national averages, and the only useful comparison is with comparable specialists in the same field.

The structure of a quote

Hourly is the dominant unit. Daily and flat figures appear mainly for deposition and trial appearance days, and at least one state's discovery statute contemplates both expressly: California's expert deposition provision refers to the expert's “reasonable and customary hourly or daily fee,” and permits a daily charge only for a full day of attendance or where the expert was required by the deposing party to be available for a full day. Cal. Code Civ. Proc. § 2034.430(b), (e).

Separate rates by activity are the norm, and testimony is priced above review in every published dataset. In the SEAK 2024 medians the difference is modest; in the means it is large, which indicates that the activity differential is concentrated among higher-billing experts. Expert Institute's engagement data shows the same ordering.

Four reasons are given in the practitioner literature for pricing testimony higher. A testimony day cannot be partially sold: the calendar is blocked whether the deposition runs two hours or eight. Testimony dates slip and cancel at short notice, often after other work has been declined. Testimony is the highest-exposure work the expert does. And there is a fourth reason, which the market does not discuss and which counsel should factor in when reading a schedule: under FRCP 26(b)(4)(E), the deposition rate is largely paid by the opposing party rather than by the retaining client. Courts have noticed. Where a deposition figure looks less like a price and more like a toll on the other side, it invites a motion, and courts have cut shifted rates back toward what the retaining party itself was paying.

Retainers, minimums and the terms that decide the bill

A retainer is normal. In an earlier edition of the SEAK series, reported around 2017 — the edition is not dated on the face of the source, so the figures should not be attributed to a particular year —74 percent of responding experts required an up-front retainer, with a median initial retainer of $2,000; 33 percent imposed a minimum billable amount for depositions and 31 percent for trial; 53 percent reported a cancellation policy retaining all or part of an appearance charge for cancellations inside a stated window; and 47 percent required a signed retention agreement before starting work.

Three structural terms decide what an engagement costs, and none of them is the headline number.

• Whether the retainer replenishes. An evergreen retainer must be topped back up to a floor as it is drawn down; a simple deposit is applied to the first invoices until exhausted. Model engagement letters in adjacent professions offer several alternative formulations, so this is a drafting choice rather than a market default, and no survey figure was located for how many experts use each form.
• Minimum increments for appearance days. Half-day and full-day minimums are the common forms, and they convert a two-hour deposition into something considerably larger.
• Cancellation terms. The notice window is the operative term. A trial date that moves inside the window is billed, and trial dates move.

Travel and waiting time have no national convention. California's statute pays the expert from the time noticed in the deposition subpoena, or from the expert's arrival if later, until dismissal, regardless of whether the expert is actually deposed. In federal fee-shifting practice some courts apply a half-rate presumption for travel and others allow the full rate.

None of it is confidential

Fee terms for a testifying expert are discoverable, by design, in two places. FRCP 26(a)(2)(B)(vi) requires the written report to contain “a statement of the compensation to be paid for the study and testimony in the case.” And FRCP 26(b)(4)(C)(i) carves communications that “relate to compensation for the expert's study or testimony” out of the work-product protection that otherwise covers attorney–expert communications. There is no such thing as a confidential fee arrangement with a testifying expert.

Some courts go further into the expert's economics. In Behler v. Hanlon, 199 F.R.D. 553 (D. Md. 2001), the court ordered disclosure of the share of the expert's gross income in each of the preceding five years attributable to expert witness services for insurers and defense counsel in personal injury cases, along with a five-year case list and a ten-year list of retaining insurers.

A fee schedule should therefore be drafted as a document the other side will read. Activity-differentiated pricing is ordinary and defensible; a deposition figure set at a multiple of the review figure is an invitation to a motion.

What the number does not tell a buyer

No study was located correlating an expert's hourly rate with admissibility outcomes, with surviving a challenge under FRE 702, or with any measure of testimony quality. So far as this research can establish, none exists. What rate correlates with is discipline — medical specialties dominate the top of every published table — along with market and how long the person has been marketing themselves for litigation work.

A high-billing surgeon and a moderately billing metallurgist are not two points on a quality scale. They are two labor markets, and the surgeon's figure reflects the value of the clinical day being given up. The most misleading thing a buyer can do with a national average is treat it as a floor and read anything below it as a discount.

Total cost is also not the hourly figure. It is the hourly figure multiplied by the hours the case actually requires, and the hours are driven by the volume of material, the number of depositions, whether a rebuttal report is needed, and how much of the record arrives late. An expert who scopes the work honestly at the outset, and says which parts of the assignment are open-ended, is describing the real cost. An expert who quotes only a rate is describing one input.

Hartzer Consulting is retained by counsel on both sides of technical matters and publishes no rate here for a reason that applies generally: a figure without a scope, a schedule and a set of terms attached to it is not a price, and a page that published one would be marketing rather than reference.
