ROI Calculator — Legal AI Time & Cost Savings
Purpose
This skill computes a concrete return-on-investment estimate for a law firm, legal department, or solo practitioner evaluating Louis. It is designed for sales conversations, procurement evaluations, and budget-justification memos — transforming abstract "AI saves time" claims into verifiable, prospect-specific numbers.
Inputs
| Input |
Description |
Typical Range |
Default if not provided |
contracts_per_week |
Number of contracts or documents reviewed weekly by the target user or team |
2 – 200 |
Ask the user |
avg_review_hours |
Average time (in hours) to review one contract manually, from open to close |
0.5 – 8 hrs |
2.0 hrs |
billable_rate |
Hourly billable rate (or effective cost rate for in-house teams) in USD or local currency |
$50 – $800/hr |
$300/hr |
time_saving_pct |
Louis's estimated time reduction per review. Default benchmark: 40%. Can be adjusted up (80% for routine contracts) or down (20% for bespoke M&A work). |
20% – 80% |
40% |
subscription_cost |
Monthly cost of Louis subscription for the user's tier |
Varies by plan |
Ask or use published pricing |
Calculation logic
hours_saved_per_week = contracts_per_week × avg_review_hours × time_saving_pct
hours_saved_per_month = hours_saved_per_week × 4.33
monthly_value_saved = hours_saved_per_month × billable_rate
payback_months = subscription_cost ÷ monthly_value_saved (if < 1, express as days)
annual_roi_pct = ((monthly_value_saved × 12) - (subscription_cost × 12))
÷ (subscription_cost × 12) × 100

Worked example
Inputs: 20 contracts/week · 2 hrs avg · $350/hr · 40% saving · $500/mo subscription.
- Hours saved/month: 20 × 2 × 0.40 × 4.33 = 69.3 hrs
- Monthly value: 69.3 × $350 = $24,255
- Net benefit: $24,255 − $500 = $23,755/mo
- Payback: 0.6 days
- 12-month ROI: 4,651%
Sensitivities to mention
- High-volume, routine contracts (NDAs, employment offers, standard service agreements): time-saving is often 60–80%. The default 40% is conservative.
- Complex bespoke deals (M&A, project finance, ISDA): saving is 20–30% and value comes from completeness and consistency, not raw speed.
- In-house teams (GC/legal ops): use fully-loaded cost per hour (salary + benefits + overhead ÷ 2,080) rather than billable rate.
- Currency: quote in the prospect's local currency (AED, SAR, LBP, EGP, EUR, GBP) for MENA markets.
Caveats
- These are illustrative estimates, not guarantees. Actual savings depend on task mix, user adoption, document complexity, and integration depth.
- Time savings do not automatically translate to billable revenue for law firms unless the freed capacity is re-billed; frame as "capacity freed for higher-value work" in firm contexts.
- For in-house teams, anchor to headcount avoidance or contract cycle-time reduction as a secondary metric.
