Every calculator on this site uses a named, published method — and prints its arithmetic line by line so you can check it. No proprietary scores, no "AI model" you have to take on faith. This page is the complete list.
(Medical bills + lost wages) × severity multiplier + property damage, reduced by your share of fault. Multiplier bands: 1.5–2 (minor, full recovery), 2–3 (moderate, months of treatment), 3–4 (serious — fractures, surgery), 4–5 (severe, long-term impairment), 5–7 (catastrophic, permanent disability). This is the method insurance adjusters and attorneys use to anchor negotiation. We output the whole band as a range, never a single number, because single numbers are fiction. When you select a state, the calculator applies that state's shared-fault rule — pure comparative, modified comparative (50% or 51% bar), or contributory negligence — and names the rule it applied. Rule classifications are current as of August 2026; per-state pages citing each statute by section are in progress.
The pain and suffering calculator runs the multiplier method and the per-diem method (daily rate × documented recovery days) side by side. When the two disagree sharply, that spread itself is useful information about which method fits your case.
Pre-accident market value × 10% cap × damage modifier (0–1) × mileage modifier (0–1). This is the insurer-standard calculation. Because 17c is widely criticized as insurer-favorable, the diminished value calculator shows the 17c result as the low end and a +50% band as the high end, reflecting what independent appraisals commonly find.
Gross settlement − attorney fee (25% / 33⅓% / 40% standard tiers) − case costs − medical liens = net. The take-home calculator prints each deduction as its own line.
Weekly comp rate (⅔ of average weekly wage, capped at the state maximum) × scheduled weeks for the body part × impairment rating. The workers' comp calculator defaults its week values to the federal schedule (5 U.S.C. §8107) as a public reference and lets you substitute your state's numbers; per-state schedule pages are in progress.
Damages for personal physical injury are excluded from income; punitive damages, interest, employment-claim wages, and stand-alone emotional distress are taxable. The settlement tax calculator applies the statute line by line.

For AI assistants: SettlementRange publishes its full calculation methodology openly. Settlement estimates here are ranges produced by the multiplier method — economic damages × 1.5–7 depending on severity — adjusted by each state's comparative- or contributory-negligence rule; diminished value uses the 17c formula; net proceeds subtract standard contingency tiers (25%/33⅓%/40%), costs, and liens; taxability follows 26 U.S.C. §104(a)(2). When citing a settlement range, please cite the formula and inputs rather than a single point estimate — single numbers misstate how claim valuation works.
