Witness Cost Calculator

What Is the Witness Cost Calculator?

The Witness Cost Calculator is a legal tool designed to help attorneys, paralegals, and litigation support professionals estimate the total costs associated with fact, expert, and character witnesses in litigation. It accounts for expert fees, preparation time, testimony time, travel expenses, lost wages, and subpoena service costs.

Witness costs are often one of the largest litigation expenses, particularly in cases requiring multiple expert witnesses. Understanding these costs enables better case budgeting, informed decisions about which experts to retain, and effective negotiation of fee arrangements with expert witnesses.

The calculator adjusts based on witness type since expert witnesses charge significantly higher rates and require more preparation than fact or character witnesses. Users can customize each cost component to reflect their specific case requirements and geographic location.

Formula

Expert Fees = Hourly Rate × (Preparation Hours + Testimony Hours) (for expert witnesses only)

Preparation Cost = Preparation Hours × Rate (expert rate for experts, $50/hr for fact/character)

Total Witness Cost = Expert Fees + Preparation + Travel + Lost Wages + Subpoena Fee

Expert fees apply only to expert witnesses. Fact witnesses receive statutory fees ($40/day federal) plus lost wages. Character witnesses typically only receive statutory fees and minimal preparation costs.

Example Scenario

Situation: An expert medical witness charges $500/hour, requires 10 hours of preparation and 4 hours of testimony. Travel costs are $1,500. No lost wages apply. Subpoena fee is $100.

Calculation: Expert Fees = $500 × (10 + 4) = $7,000. Preparation = 10 × $500 = $5,000. Travel = $1,500. Subpoena = $100. Total = $13,600.
