Business Case
A practical way to model legal AI ROI
How to turn reclaimed time into a transparent capacity estimate without treating an illustration as a guarantee.
A useful ROI model should make its assumptions visible. The goal is not to promise a financial result. It is to help partners and finance leaders compare scenarios using the team size, rates, adoption, and conversion assumptions that make sense for their firm.
Separate time saved from value created
Not every reclaimed hour becomes additional revenue. Some time improves client service, reduces write-offs, protects personal capacity, or makes fixed-fee work healthier. A transparent model shows the full time estimate and then applies a separate realization assumption.
This prevents an operational benefit from being presented automatically as billable revenue.
Use inputs the firm can challenge
The most productive business-case discussion often comes from changing the assumptions. Model conservative, expected, and strong-adoption scenarios rather than presenting one precise number as inevitable.
- Number of participating people
- Average hours reclaimed per person
- Blended hourly value or internal capacity value
- Percentage of time converted into usable capacity
- Adoption over the first three years
- Platform and implementation cost
Measure operational outcomes alongside dollars
A financial model should sit beside direct workflow measures. Time to understand an inherited file, client follow-up volume, time spent locating source material, and handoff speed can show whether the expected benefit is appearing before revenue patterns change.
Treat the result as a planning scenario
The result belongs in an internal discussion, not a guarantee. Record the assumptions, revisit them after a pilot, and replace estimates with observed firm data as adoption grows.
That discipline turns the calculator into a decision tool rather than a sales claim.
