Ask what an expert witness costs and you will hear a number. Ask what the market costs and you get a distribution — and in 2026, that distribution has a new record attached. The ExpertPages survey of more than 400 experts put the average hourly fee at $465, up from $451 in 2024 and $408 in 2022. SEAK's 2024 fee study, covering more than 1,100 experts across 250-plus specialties, reported medians of $450 per hour for file review, $475 for deposition, and $500 for trial testimony.
But the all-expert average conceals the real story, which is specialty. An orthopedic surgeon's hour and a general contractor's hour are not the same commodity, and they do not clear at the same price.
The Fee Hierarchy
Medicine sits at the top. Medical experts average roughly $597 per hour — the highest of any category — with orthopedic surgeons and neurosurgeons commanding $600 to $1,000 per hour and some marquee names exceeding $1,500. The economics are straightforward: a practicing surgeon who testifies is selling hours taken from an operating schedule, and the opportunity cost is enormous. Treating physicians who get pulled into testimony they never sought are a separate, cheaper category — but retained experts price like the scarce resource they are.
Economists and finance experts run $500 to $900 per hour. Damages experts in particular command premiums because their testimony often determines the size of the award — the expert who quantifies a $40 million lost-profits claim is worth more per hour than the expert who authenticates a photograph. Forensic accountants cluster at $400 to $750, with Big Four alumni and credentialed specialists (CPA/ABV, CFF) at the top of the band.
Engineers are the value tier of the top half: $350 to $600 per hour for consulting and report work, with deposition and trial premiums pushing specialized experts — structural, geotechnical, building envelope — past $700. Digital forensics, one of the fastest-growing specialties, runs $300 to $500 for examination and report work, with senior court-qualified examiners at $400 to $500 and niche specialists in cell-site analysis or video authentication reaching $500 to $750.
Deposition and Trial: Where the Premiums Live
The step-up from review to testimony is where fee schedules get interesting, and it varies sharply by field. Medical experts commonly charge 10 to 30% more for deposition and trial than for file review — a surgeon billing $450 for record review may charge $825 for trial, often with day minimums. Engineers, by contrast, frequently quote a single flat rate or a modest step-up; Expert Institute placement data shows engineering at a flat $333 across review and testimony on average, though credentialed specialists diverge upward.
Roughly three-quarters of experts require a minimum fee or retainer before accepting a case, and most earn more than $10,000 per engagement. Total case spend is what actually matters for budgeting: a medical malpractice case with thousands of pages of records, a deposition, and trial testimony commonly reaches $15,000 to $30,000 in total expert fees. Engineering and construction cases with site inspections, testing, and technical reports can reach $30,000 to $40,000 or more — proportionate, usually, to multi-million-dollar disputes.
The geography surcharge is real: experts in major metropolitan markets typically command 10 to 25% more than those in smaller markets. And the trend line points one direction. Fees have risen every survey cycle for a decade, driven by demand growth in complex litigation and the simple fact that the supply of credible, court-tested experts does not scale.
Retainers, Minimums, and the Fine Print
The hourly rate is the headline. The engagement letter is the real price. Roughly three-quarters of experts require a minimum fee or retainer before accepting a case — commonly $2,500 to $10,000 depending on specialty, credited against future work. This is non-negotiable for most established experts, and it serves a purpose beyond cash flow: it filters out the attorneys who are shopping for free opinions.
Cancellation terms are where unwary litigators get burned. Many experts charge premium or full-day rates for depositions or trial testimony canceled on short notice — 50 to 100% of the day rate for cancellations within 48 to 72 hours is standard. An expert who has blocked three trial days and turned away other work expects to be paid for them. Get the cancellation window in writing before you need it.
Travel billing varies more than any other term. Some experts bill portal-to-portal at the full hourly rate. Others bill travel at half rate. A few build travel into flat day rates for testimony. On a case requiring cross-country travel, the difference between these policies can swing total cost by thousands of dollars — which is why the fee agreement should specify travel terms explicitly rather than leaving them to a handshake.
Then there is the question everyone asks and no one puts in writing: what does the expert charge to be destroyed on cross-examination? Nothing extra. But the far more expensive scenario is the expert who was retained cheap, prepared thinly, and excluded under Daubert — costing the case itself. The fee schedule is the least important document in the engagement. The CV, the transcript history, and the methodology are the ones that decide outcomes.
"The cheapest expert is the one you pay twice — once for the opinion, and once for the case it loses you."
