name: docs-roi-calculator
description: Use when a prospective customer or sales team member asks about the financial return of deploying a legal AI assistant, or when handling a cost-based sales objection. Generates a quantified monthly savings estimate and payback period from three simple inputs — contracts reviewed per week, average review time, and billable hourly rate — mapped against Louis's time-saving benchmark. Applicable across all jurisdictions and firm sizes.

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	– /hr	/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 · /hr · 40% saving · /mo subscription.

• Hours saved/month: 20 × 2 × 0.40 × 4.33 = 69.3 hrs
• Monthly value: 69.3 × = ,255
• Net benefit: ,255 − = ,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.
