Cost Breakdown
What Is the Discovery Cost Calculator?
The Discovery Cost Calculator is a legal tool designed to help attorneys, paralegals, litigation support professionals, and clients estimate the total costs associated with the discovery phase of litigation. It accounts for document review, electronic data processing, attorney and paralegal time, e-discovery software licensing, deposition expenses, and interrogatory preparation.
Discovery often represents the most expensive phase of litigation, sometimes accounting for 50-80% of total case costs. Understanding these costs upfront enables better budgeting, informed settlement decisions, and effective proportionality arguments under the Federal Rules of Civil Procedure.
By inputting case-specific variables, users can generate realistic cost projections that reflect current market rates for legal services and e-discovery technology. These estimates serve as a foundation for discovery planning, cost-sharing negotiations, and fee petition preparation.
Formula
Document Review = Document Count × $0.75 per document
ESI Processing = Data Volume (GB) × $150 per GB
Attorney Review = Attorney Hours × $350 per hour
Paralegal Services = Paralegal Hours × $125 per hour
Deposition Costs = Number of Depositions × $5,000 per deposition
Interrogatory Costs = Number of Interrogatories × $2,500 per set
Total Discovery Cost = Document Review + ESI Processing + Attorney Review + Paralegal Services + E-Discovery Software + Deposition Costs + Interrogatory Costs
Example Scenario
Situation: A commercial litigation case involves 5,000 documents, 50 GB of ESI data, 100 attorney review hours, 80 paralegal hours, $5,000 in e-discovery software, 3 depositions, and 2 sets of interrogatories.
Calculation: Document Review = 5,000 × $0.75 = $3,750. ESI Processing = 50 × $150 = $7,500. Attorney Review = 100 × $350 = $35,000. Paralegal Services = 80 × $125 = $10,000. Software = $5,000. Depositions = 3 × $5,000 = $15,000. Interrogatories = 2 × $2,500 = $5,000. Total = $81,250.

Frequently Asked Questions
- Discovery cost refers to the expenses incurred during the pre-trial phase where parties exchange relevant information and evidence. These costs include document review, electronic data processing, attorney review hours, paralegal work, e-discovery software, depositions, and interrogatories.
- Discovery costs are calculated by summing document review costs, ESI processing fees, attorney review hours, paralegal hours, e-discovery software expenses, deposition costs, and interrogatory expenses. The formula is: Total = DocumentReview + ESIProcessing + AttorneyReview + Paralegal + Software + DepositionCosts + InterrogatoryCosts.
- ESI (Electronically Stored Information) includes emails, documents, databases, social media content, and other digital evidence. Processing ESI requires specialized software and expertise, making it one of the most significant discovery cost factors.
- E-discovery software costs vary widely from $50 to $500+ per GB of data processed. Cloud-based solutions like Relativity, Everlaw, and Logikcull charge per GB or per user. Enterprise licenses can cost $10,000 to $100,000+ annually.
- Document review costs depend on document volume, review platform used, reviewer expertise level, document complexity, language requirements, and timeline urgency. First-pass review costs range from $0.50 to $2.00 per document.
- Document volumes vary dramatically by case complexity. Simple cases may involve 1,000-10,000 documents, while complex commercial litigation can involve millions of documents. Class actions and antitrust cases often have the highest volumes.
- Attorney review rates range from $150 to $600+ per hour depending on experience level. Junior associates typically bill $150-$300, senior associates $300-$500, and partners $500-$800+ per hour for discovery review.
- Paralegals handle document organization, privilege logs, database management, and exhibit preparation. Paralegal rates range from $75 to $200 per hour. Their work is essential for efficient discovery management.
- Deposition costs include court reporter fees ($250-$800 per day), videographer fees ($300-$1,000 per day), transcript costs ($3-$6 per page), attorney preparation time, and witness fees. A single deposition typically costs $2,000-$10,000.
- Interrogatory costs include attorney time to draft and respond to written questions, expert consultation for technical questions, and document gathering. Each set of interrogatories may cost $1,000-$5,000 in attorney time alone.
- Discovery costs can be reduced through early case assessment, targeted discovery requests, technology-assisted review (TAR), predictive coding, proportionality-focused strategies, and negotiated discovery protocols with opposing counsel.
- Proportionality under FRCP 26(b)(1) requires that discovery be proportional to the needs of the case, considering the amount in controversy, parties' resources, issue importance, and burden versus benefit. Courts increasingly enforce proportionality.
- TAR uses machine learning algorithms to identify relevant documents more efficiently than manual review. TAR can reduce review costs by 40-80% while maintaining or improving accuracy compared to linear manual review.
- Data volume directly impacts storage, processing, review, and hosting costs. Each terabyte of data can cost $20,000-$100,000+ to process and review. Reducing data volume through early filtering and deduplication is critical for cost control.
- A privilege log lists documents withheld from discovery due to attorney-client privilege or work product protection. Preparing privilege logs requires attorney review of each document, often costing $1-$5 per document logged.
- Federal courts follow the FRCP with specific proportionality and preservation requirements. State court rules vary widely. Federal discovery tends to be more standardized but can involve higher e-discovery costs due to stricter requirements.
- Data collection costs include forensic imaging, cloud data collection, mobile device extraction, and metadata preservation. Costs range from $500-$5,000 per device or custodian, depending on collection complexity.
- Cloud data from Office 365, Google Workspace, Slack, and other platforms adds complexity and cost. Collecting, processing, and reviewing cloud data often requires specialized tools and APIs, increasing overall discovery expenses by 20-40%.
- ECA involves reviewing key data early to understand case strengths and weaknesses before full discovery. ECA tools and processes cost $5,000-$25,000 but can save $50,000-$500,000+ by enabling early settlement or targeted discovery.
- The most expensive discovery types include forensic data collection, international discovery (compliance with foreign privacy laws), massive document reviews (1M+ documents), and expert discovery involving complex technical or scientific evidence.
- High discovery costs often motivate early settlement, particularly in cases where discovery expenses would approach or exceed the potential recovery. Parties regularly conduct cost-benefit analyses comparing discovery costs to case value.
- A discovery budget projects all anticipated discovery costs including collection, processing, review, depositions, and expert discovery. Budgets help parties control costs, support proportionality arguments, and inform settlement strategy.
- Personal injury cases typically have lower discovery costs ($5,000-$50,000). Commercial litigation ($50,000-$500,000), antitrust ($500,000-$5M+), and securities class actions ($1M-$10M+) have substantially higher discovery costs due to data volumes.
- A special master appointed by the court oversees discovery disputes and protocols. Costs are split between parties and typically range from $300-$800 per hour. Special masters can reduce overall costs by streamlining discovery.
- International discovery involves foreign data privacy laws (GDPR, LGPD), language translation, cross-border data transfers, and international counsel coordination. Costs can be 2-5 times higher than domestic discovery.
- Predictive coding uses supervised machine learning where attorneys code a seed set of documents, and the algorithm predicts relevance for the remaining documents. It reduces review costs by 50-80% compared to linear review.
- Generally, each party bears its own discovery costs. However, courts may shift costs for unduly burdensome requests, and parties can negotiate cost-sharing agreements for third-party discovery or common benefit discovery.
- The cheapest approach involves early case assessment, negotiated limited discovery protocols, using free or low-cost review tools, leveraging technology-assisted review, and maintaining organized data management practices from the outset.
- Platforms charge per GB hosted ($10-$50/month), per user subscription ($500-$5,000/user/year), or per document reviewed ($0.25-$1.00). Hybrid pricing models are common. Total platform costs for a mid-size case range from $10,000-$100,000.
- Spoliation sanctions can include monetary penalties, adverse inference instructions, or case-dispositive sanctions. Defense costs for spoliation motions range from $10,000-$100,000, and adverse inference instructions can effectively lose the case.
- Plaintiffs typically produce their own documents and respond to discovery requests. Defendants often bear higher costs as primary data holders. However, both sides face similar costs for depositions, expert discovery, and motion practice.
- Cost estimates inform budgeting, settlement negotiations, fee petitions, and proportionality arguments. Accurate estimates help attorneys advise clients on litigation strategy and whether alternative dispute resolution is more cost-effective.
- Discovery begins with initial disclosures (required under FRCP 26), followed by written discovery requests (interrogatories, requests for production, requests for admission), and then depositions and expert discovery. Each phase adds incremental costs.
- Agreed discovery protocols reduce disputes, streamline production formats, limit privilege log requirements, and establish cost-effective review procedures. Parties can save 20-40% of discovery costs through negotiated protocols.
