Frequently Asked Questions

Frequently Asked Questions

How do you calculate legal AI ROI?

Calculate ROI by comparing time savings (hours saved x hourly rate) plus error reduction value against software costs. Include both direct savings from faster document review and indirect benefits like faster deal closure and reduced risk of missed issues.

What is the typical payback period for legal AI?

Many firms see positive ROI within 2-3 matters, depending on deal volume and document complexity. First-pass review time reductions of 60-80% are common, which can translate to significant savings on large data room reviews.

How does legal AI affect billable hours?

AI typically shifts billable time from low-value document review to high-value analysis and strategy. While total hours per matter may decrease, firms can handle more matters and compete more effectively on fixed-fee arrangements. Revenue per attorney often increases.

What hidden costs should I consider with legal AI?

Consider implementation time, training costs, workflow redesign, and change management. Also evaluate whether the AI integrates with existing tools or requires separate workflows. The most successful implementations invest in proper onboarding and attorney training.
