How Our Litigation Cost Estimator Works

Our litigation cost estimator calculates comprehensive legal expenses using market-rate attorney billing and typical litigation cost components. The calculator factors in attorney time by level, expert witness requirements, deposition costs, discovery expenses, and court fees to provide accurate total cost projections with realistic ranges.

Litigation Cost Calculation Formula

Attorney Fees:
(Partner Hours × $550) + (Senior Hours × $400) + (Associate Hours × $275) + (Paralegal Hours × $150)
Litigation Expenses:
Court Filing Fees + (Depositions × $2,500) + (Experts × $15,000)
+ E-Discovery ($5,000 + Duration × $500) + Transcripts + Travel
Total Litigation Costs: Attorney Fees + All Expenses
Cost Range: Total × (0.7 to 1.3) for ±30% uncertainty
Monthly Burn Rate: Total Costs / Duration (months)

This methodology reflects actual litigation cost structures where attorney fees typically represent 60-75% of total costs, expert witnesses 10-20%, depositions and discovery 10-15%, and court/administrative costs 5-10%. Costs can vary ±30% based on case developments and opposing counsel tactics.

Understanding Litigation Cost Components

Litigation costs extend far beyond attorney fees. Expert witnesses provide critical testimony but cost $15,000-$50,000+ each. Depositions cost $2,500-$4,000 each including court reporters and transcripts. E-discovery for document-intensive cases can range from $10,000 to $500,000+. Understanding all cost components helps firms provide accurate budgets and helps clients make informed decisions about pursuing litigation versus settlement.

  • Attorney fees vary by level: Partners $400-$800/hr, Associates $200-$350/hr
  • Expert witnesses cost $10,000-$50,000+ for reports and testimony

  • E-discovery costs scale with data volume ($500-$2,000 per GB)
  • Trial adds 100-200% to costs with preparation and daily expenses
