How often are financial expert witnesses excluded under Daubert?

More than any other discipline: across 1,500+ published opinions over 14 years (PwC's study), 46% of Daubert challenges to financial experts succeeded, with roughly a third of challenged experts at least partially excluded in recent years. Lack of reliability — not credentials — is the leading cause.

How much do forensic accounting experts charge in 2026?

Forensic accountants typically charge $400–$650/hour; economic and financial-damages experts average about $525/hour. Complex engagements (fraud reconstruction, business valuation disputes) also carry substantial analyst-team hours beyond the testifying expert's rate.

What methodology mistakes get damages testimony excluded?

The classics: lost-profits projections untethered to historical performance or market data, ignoring causation between the wrongdoing and the loss, misapplying accepted valuation methods (income/market/asset approaches), double-counting damages, and assuming rather than analyzing key inputs. Courts exclude misused accepted methods just as readily as novel ones.

Forensic Accounting & Financial Expert Witnesses: the Highest Daubert Risk in Litigation

By SwornIn · Informational only — not legal advice.

The number that should change how you vet: across more than 1,500 published opinions over 14 years, 46% of Daubert challenges against financial experts succeeded (PwC). No other discipline faces this exclusion pressure — which makes the financial expert's reliability record the single most important selection criterion in any damages-heavy case.

What financial experts cost

Forensic accountants typically charge $400–$650/hour; economic and financial-damages experts average ~$525/hour. Budget beyond the testifying expert: fraud reconstructions and valuation disputes carry significant analyst-team hours. Cross-specialty comparison: 2026 fee guide.

Why financial testimony gets excluded

The pattern in the case law is consistent — it's rarely the credentials, and it's rarely a novel method. It's accepted methods, unreliably applied:

Lost profits from thin air. Projections untethered to historical performance, industry benchmarks, or market reality.
Causation skipped. Damages models that quantify a loss without reliably connecting it to the alleged wrongdoing.
Valuation drift. Income/market/asset approaches misapplied, discount rates assumed rather than derived, terminal values doing all the work.
Double counting and inconsistent assumptions across report sections — the cross-examiner's favorite gift.
Garbage inputs. Under amended Rule 702's "sufficient facts or data" prong, uncritically adopting management's projections is a target.

Discipline-level context: appraisers face ~38% exclusion rates, accountants ~32%, economists ~27%. The full data is in The State of Expert Witness Testimony 2026.

The vetting checklist

Credentials that match the task: CPA plus CFF/ABV for valuation; CFE for fraud; PhD economics for market/antitrust damages
The Daubert record, above all: prior exclusions and limitations, and what the opinions actually said about their methodology
Sample reports (redacted) — look for derived assumptions, sensitivity analyses, and causation linkage
Cross-examination durability: read prior transcripts if available
Independence: testimony share of income, plaintiff-defense balance, prior relationships with parties/counsel
