Relativity is the industry-leading eDiscovery and legal analytics platform used by law firms, corporations, and government agencies worldwide to manage the complete litigation discovery lifecycle. RelativityOne, its cloud-based SaaS product, provides integrated tools for legal hold, early case assessment, data processing, document review, production, analytics, and AI-assisted review. Available in 17 countries with 24/7/365 support, Relativity has the largest ecosystem of service providers and integrations in the eDiscovery market.

RelativityOne uses consumption-based pricing charged per GB of data per month, with no per-user license fees (eliminated in 2022). Exact per-GB rates are not publicly disclosed and depend on data volume, commitment length, and negotiated terms. Industry estimates suggest processing at ~$35/GB and hosting at ~$25/GB/month, though Relativity has reduced prices by up to 60% in recent years. Pay-as-you-go plans require no commitment, while Flex Commit subscriptions (1-year or 3-year) offer up to 25% discounts from standard rates.

Key considerations before purchasing: billing is based on peak day review data volume, meaning large case spikes can dramatically increase monthly costs. Data processing, third-party hosting markups (20-50% from service providers), and overage penalties on Flex Commit plans represent significant hidden costs. However, Relativity's elimination of per-user fees, bundled AI features (aiR for Review and aiR for Privilege), and tiered storage rates (cold storage at 25% of active rates) provide meaningful cost optimization opportunities.

In this 2026 pricing guide, we break down RelativityOne's consumption-based pricing model, identify hidden costs like processing fees and hosting markups, explain the differences between pay-as-you-go and Flex Commit plans, and compare Relativity to alternatives like Everlaw, DISCO, and Nuix to help you choose the right eDiscovery platform for your organization.

Hidden Costs to Budget For

Watch for 6 hidden costs
  • Data volume billing surprises: RelativityOne bills based on peak day review data volume each month, meaning a single large case with massive document ingestion can spike your monthly bill dramatically -- a 500GB spike during a litigation hold can cost $12,500-$25,000 in a single month at estimated $25-$50/GB rates
  • Processing fees add up quickly: Data processing (converting native files to reviewable formats) is typically billed separately at approximately $35/GB, turning a 100GB document collection into a $3,500 processing charge before you even begin review -- this cost is often overlooked in initial budgeting
  • Third-party hosting markups: Many organizations access RelativityOne through eDiscovery service providers (like HaystackID or KLDiscovery) who add 20-50% markups on top of Relativity's base rates for managed services, support, and project management
  • Overage penalties on Flex Commit plans: If your data volume exceeds your committed allocation, overage rates can be 25-50% higher than your negotiated per-GB rate -- organizations with unpredictable litigation volumes risk significant overage charges
  • Analytics and AI add-on costs: While Relativity now bundles some AI features (aiR for Review, aiR for Privilege), advanced analytics, technology-assisted review (TAR), and custom AI workflows may incur additional per-project or per-matter charges beyond base data hosting
  • Migration and switching costs: Moving existing matters from a Relativity Server (on-premise) installation to RelativityOne SaaS involves data migration fees, workflow reconfiguration, and potential downtime -- budget $20,000-$100,000+ for enterprise migrations depending on data volume and complexity
Tip

Ask your Relativity sales rep about these costs upfront. Getting them in writing before signing can save you from surprise charges later.

Frequently Asked Questions

01 How much does Relativity cost?

Relativity (RelativityOne SaaS) uses consumption-based pricing charged per GB of data per month, with no per-user license fees. Exact per-GB rates are not publicly disclosed and depend on data volume, commitment length, and negotiated terms. Illustrative industry figures suggest processing at ~$35/GB and hosting at ~$25/GB/month, though Relativity has lowered prices by up to 60% in recent years. Pay-as-you-go plans require no commitment, while Flex Commit subscriptions (1-year or 3-year) offer up to 25% discounts.

02 Is Relativity free?

No, Relativity does not offer a free plan. RelativityOne is an enterprise eDiscovery platform with consumption-based pricing requiring a paid subscription. Relativity does offer product demos and consultations through their sales team. For free or lower-cost eDiscovery alternatives, consider open-source tools like ZyLAB ONE Essentials, or basic document review tools included with practice management platforms like Clio ($39-$139/user/month).

03 What is RelativityOne?

RelativityOne is Relativity's cloud-based (SaaS) eDiscovery platform, replacing the traditional Relativity Server on-premise product. It provides an integrated suite of tools spanning legal hold, early case assessment, data processing, document review, production, analytics, assisted review (TAR), and fact management. RelativityOne is available in 17 countries with 24/7/365 support and now includes generative AI features (aiR for Review and aiR for Privilege) at no additional cost. It has eliminated per-user license fees, charging only based on data volume.

04 How does RelativityOne pricing work?

RelativityOne charges based on data volume rather than per-user seats. Each month, billing is calculated based on the peak day review data volume across all workspaces. Early case assessment data is billed at 33% of active review rates, cold storage archives at 25%, and video/rich media at 50%. Customers can choose pay-as-you-go (no commitment), 1-year Flex Commit (up to 25% discount), or 3-year Flex Commit (deepest discounts). Per-user license fees were eliminated in 2022.

05 Relativity vs Harvey AI: which is better?

Relativity and Harvey AI serve fundamentally different purposes. Relativity is an eDiscovery platform for document collection, processing, review, and production in litigation and investigations. Harvey AI is a legal research and drafting tool using large language models. Choose Relativity if you need to manage eDiscovery workflows, conduct document review, and produce documents for litigation. Choose Harvey AI if you need AI assistance for legal research, memo writing, and contract drafting. Many large firms use both tools for their respective functions.

06 What is the difference between RelativityOne and Relativity Server?

RelativityOne is Relativity's cloud-based SaaS product with consumption-based pricing, automatic updates, and no infrastructure management required. Relativity Server is the traditional on-premise product that organizations host on their own infrastructure. Relativity has been actively encouraging migration to RelativityOne with lower pricing (up to 60% reductions), bundled AI features, and eliminated per-user fees. New customers are typically directed to RelativityOne, while Relativity Server remains available for organizations with specific on-premise requirements.

07 Does Relativity charge per user?

No, Relativity eliminated per-user license fees for RelativityOne in late 2022. Previously, per-user fees were approximately $100/month/user. Now, RelativityOne charges based solely on data volume (per GB/month), with unlimited users included at no additional cost. This pricing change was designed to encourage broader platform adoption and remove cost barriers for adding reviewers, project managers, and attorneys to matters. Legal Hold functionality was also rolled into the data tier pricing model.

08 What are the alternatives to Relativity?

Key eDiscovery alternatives to Relativity include Everlaw (cloud-native eDiscovery with predictive coding), Nuix (data processing and investigation platform), Logikcull (simplified cloud eDiscovery), DISCO (AI-powered eDiscovery), and Exterro (end-to-end legal GRC with eDiscovery). For organizations needing legal AI rather than eDiscovery, consider Harvey AI ($100-$500/user/month), CoCounsel ($220-$500/user/month), or Clio ($39-$139/user/month). Relativity is the market leader in eDiscovery with the largest ecosystem of service providers and integrations.

09 What AI features does Relativity include?

Relativity now includes two generative AI features at no additional cost for RelativityOne customers: aiR for Review (AI-assisted document review that identifies relevant documents and generates review rationales) and aiR for Privilege (automated privilege detection). The platform also includes technology-assisted review (TAR/predictive coding), analytics dashboards, clustering, email threading, and concept searching. These AI capabilities significantly reduce manual review time and costs on large document collections.
