Expert Witness Cost Estimator
Estimates total expert witness costs including retainer, preparation time, deposition, trial testimony, and travel expenses.
Formulas Used
Review & Report Cost = Review Hours × Hourly Rate
Deposition Cost = (Deposition Prep Hours + Deposition Testimony Hours) × Hourly Rate
Trial Testimony Cost = Trial Days × Billable Hours per Day × Hourly Rate
Trial Preparation Cost = Trial Prep Hours × Hourly Rate
Travel Time Cost = Travel Days × 8 × (Travel Rate % ÷ 100) × Hourly Rate
Travel Expenses = Airfare + (Hotel Nights × Hotel Rate per Night)
Total per Expert = Retainer + Review + Deposition + Trial Testimony + Trial Prep + Travel Time + Travel Expenses + Miscellaneous
Grand Total = Total per Expert × Number of Experts
Budget Range = Grand Total × 0.85 (low) to Grand Total × 1.20 (high)
