What this calculator does NOT model
- Multi-touch attribution — every lead is credited 100% to the spend you entered.
- Settlement timing — contingency cases collect 3–18 months after sign; this assumes same-month cash.
- Practice-area variance — one case-value input across PI, family, criminal, etc.
- Channel mix — organic, paid, social, GBP, and AI-citation referrals are treated identically.
- Platform fees beyond ad spend (unless you entered one above).
LexGrow customers see all of this in the Composite ROAS dashboard after ~3 months of data, with 95% confidence intervals and per-channel breakdown.
