1. Where These Numbers Come From
Retaining a credentialed expert witness is among the most financially significant tactical decisions litigators make. This guide reports what experts actually charge in 2026, and every figure below is drawn from one of two published primary sources:
- The 2026 ExpertPages® Expert Witness Fees & Practices Survey — confidential responses from more than 400 expert witnesses and litigation consultants across North America, conducted by the independent research firm DeBow Communications; the survey has tracked the field since 2008. The full Top Line Report is a free download.
- The Expert Institute Fee Calculator — fee data compiled from more than 100,000 expert–attorney connections, broken out by specialty and by phase of work.
We publish nothing here we cannot point to. Where the two sources differ, we show both, because they measure different populations: a broad self-reported survey versus fees observed in actual placements.
2. The Headline Numbers for 2026
- Average hourly fee, all fields: $465/hour, up from $451 in 2024, with reported rates ranging from under $200 to over $1,500/hour (ExpertPages 2026 survey).
- Average by phase of work: $356/hour for initial case review, $448/hour for deposition, and $478/hour for trial testimony (Expert Institute, 100,000+ cases).
- Billing structure: 98% of experts charge hourly or a combined hourly/flat-fee model (ExpertPages).
3. Rates by Specialty
Per-specialty averages from the Expert Institute's placement data (hourly, in the order review / deposition / trial):
- Neurology: $700 / $825 / $825
- General Surgery: $450 / $775 / $825
- Emergency Medicine: $371 / $421 / $454
- Economics: $323 / $412 / $425
- Engineering: $333 across all three phases
- Appraisal & Valuation: $463 across all three phases
- Transportation: $283 / $333 / $350
Two patterns worth noting: physicians in surgical and neurological specialties command the highest premiums, and nearly every specialty bills deposition and trial time above review time. The full specialty table, including dozens more fields, is on the source page.
4. Minimums, Retainers & Per-Case Economics
Hourly rate is only part of the cost picture. From the ExpertPages 2026 survey:
- Minimum fees are now standard: 74% of experts require a minimum fee to accept a new engagement, and 40% set that minimum between $2,500 and $4,999.
- Typical per-case earnings: 55% of experts earn more than $10,000 per case; 4% report earning over $50,000 per case.
- Capacity is limited: 52% of experts take fewer than 10 case assignments per year, and 83% have been practicing in their field for 10 years or more — retaining early matters.
Beyond those measured figures, two contractual terms appear routinely in expert engagement letters and are worth reading closely before signing: replenishing ("evergreen") retainers, where the firm must top the retainer back up as hours are billed against it, and portal-to-portal travel billing, where the expert bills from departure to return, not just time on the stand. Cancellation terms for trial dates vary widely — ask for them in writing. We cite no numbers for these because no published survey we are aware of measures them; treat any source that quotes precise "standard" cancellation percentages with suspicion.
