What it is
Batch present-value model of future lost earnings across a plaintiff class. Takes a CSV or JSON of claimants (age, annual income, retirement age or work-life years, jurisdiction, injury type) plus shared economic assumptions (wage growth and discount rates), and computes each claimant's present value both term-by-term and by the closed-form geometric series, cross-checking the two. Applies a cited statutory damages cap only where one is embedded for the jurisdiction and tort, and flags everywhere else. Rolls the class up with a total and min / median / max distribution, charts the per-claimant distribution, and exports every projection to CSV. The math is cross-checked in-browser with no data leaving the page; the rates and work-life horizons are expert assumptions and this is a modeling aid, not legal or economic advice.
Honest scope
Deterministic and citation-backed: every figure is exact arithmetic or a cited rule. Any year- or jurisdiction-indexed value is a confirmable input, never an eternal hardcode. This is a computation tool, not professional (legal, tax, medical, or financial) advice - confirm against the controlling authority for your context.
