The Real ROI of Legal AI: How Much Time and Money Lexiel Saves Your Firm
We calculated the real return from using Lexiel with data from our attorneys. Hours saved per task, what that means in euros, and how quickly the subscription pays for itself.
The Number That Changes Everything: €150/hour
A practicing attorney in Spain charges between €80 and €300/hour depending on specialty and location. The weighted average for mid-size firm attorneys is around €150/hour.
With that figure, every hour Lexiel frees is an hour you can bill to a client, dedicate to a new matter, or simply not work in the evening. The ROI of legal software isn't abstract, it's real hours multiplied by your hourly rate.
Where Lexiel Saves the Most Time
We measured real usage from over 200 attorneys during their first 8 weeks with Lexiel. These are average savings by task type:
#### Legal Research
Without Lexiel: finding relevant case law in CENDOJ takes 1.5 to 4 hours. Manual filters, reading summaries, discarding non-applicable rulings.
With Lexiel: semantic search in natural language ("judgments on floor-rate clauses in variable mortgages since 2015") returns the 5-10 most relevant results in seconds, with ruling extracts. Average time: 12 minutes.
Average savings per search: 2.5 hours → €375 at €150/h.
#### Drafting Procedural Briefs
Without Lexiel: an ordinary complaint takes 4 to 6 hours including structure, client data entry, legal grounds, and petition.
With Lexiel (Procedure Engine): a complete draft generates in 3-5 minutes. Legal review and customization takes 45-90 minutes.
Average savings per brief: 4 hours → €600 at €150/h.
#### Contract Analysis
Without Lexiel: reading a 30-page contract and identifying problematic clauses: 90-150 minutes.
With Lexiel: analysis of abusive clauses, risks, and legal references generates in 2-3 minutes. The attorney reviews and adds context: 15-20 minutes.
Average savings per contract: 1.5 hours → €225 at €150/h.
#### Procedural Deadline Tracking
Without Lexiel: manually calculating deadlines by procedure type, official calendar, regional holidays, court non-business days: 20-45 minutes per complex matter.
With Lexiel: automatic calculation with email/WhatsApp alerts. Time spent: essentially zero.
Average savings per complex calculation: 30 minutes → €75 at €150/h.
ROI in a Typical Working Month
An attorney actively using Lexiel with 15 active matters can expect:
| Task | Frequency/month | Savings per task | Monthly savings |
|---|---|---|---|
| Legal research | 20 queries | 2.5 h | 50 h |
| Procedural briefs | 6 briefs | 4 h | 24 h |
| Contract analysis | 4 contracts | 1.5 h | 6 h |
| Deadline tracking | 15 matters | 0.3 h | 4.5 h |
| Total | 84.5 hours/month |
At €150/hour: €12,675 of recovered value per month.
Lexiel's Starter plan costs €69/month (annual). The payback period is essentially immediate, within the first brief of the month.
Not All Recovered Hours Are Equal
There's an important qualitative difference between types of hours saved:
Evening and weekend hours: Lexiel lets you do in 15 minutes what used to mean staying until 10pm. The impact on personal wellbeing is hard to quantify in euros but very real.
Low-concentration hours: The mechanical work of copying client data into briefs demands concentration to avoid errors but adds no intellectual value. Eliminating it improves the quality of strategic work.
Capacity for more clients: If you reduce 80 hours of monthly work, you can take on 1-2 more clients without extending hours. At an average ticket of €1,500/client/month, that's €1,500-€3,000 in additional revenue.
What Lexiel Includes Beyond Time Savings
Time ROI is the most visible, but Lexiel also reduces costs in other ways:
Error reduction: Mistakes in client data, miscited articles, or confused procedural deadlines have real costs (corrections, unbilled hours, reputation). With automatic verification, that risk drops.
More complete billing: Lexiel's time tracking module automatically records time spent on each matter. Attorneys who use it bill an average of 15-20% more hours (they're not inventing them; they were simply forgetting to charge for work they were doing).
Client retention: Clients who use Lexiel's portal to track their matter status and receive communications have higher renewal rates. Transparency builds loyalty.
How to Measure Your Own ROI
Lexiel includes a usage and impact dashboard that shows:
- Hours saved in the last month, by task category
- Economic equivalent at your hourly rate
- Comparison with the previous month
If you want an estimate before subscribing, our ROI calculator on the website gives a projection based on your practice type and number of active matters.
Conclusion
Lexiel's return on investment is concrete and fast. It's not abstract "digital transformation", it's real hours that stop being mechanical work and become billable time, strategic thinking, or simply personal time.
At €69/month (annual) for a solo practitioner, the break-even point is one saved case law search. Everything else is net profit.
