Negligence Damages Estimator

Estimates total compensatory damages in a negligence case, including economic losses (medical expenses, lost wages, future losses) and non-economic losses (pain and suffering), adjusted for comparative fault.

Economic Damages

Non-Economic Damages

Comparative Fault & Caps

Formulas Used

Future Lost Earning Capacity (Present Value Annuity):
PV = Annual Earnings × [1 − (1 + r)^(−n)] / r
where r = discount rate per year, n = years of loss. If r = 0, PV = Annual Earnings × n.

Pain & Suffering (Per Diem Method):
Pain & Suffering = Daily Rate × Number of Days

Gross Total Damages:
Gross = Total Economic + Total Non-Economic (subject to any statutory cap)

Net Recoverable Damages:
Net = Gross × (1 − Plaintiff's Fault %)
Subject to bar rules: Pure (always recovers), Modified 50% (barred if fault ≥ 50%), Modified 51% (barred if fault > 50%), Contributory (barred if any fault).

Assumptions & References

  • Future losses are discounted to present value using a constant annual discount rate (default 3.5%, consistent with U.S. Treasury long-term rates).
  • The per diem method for pain and suffering is accepted in many jurisdictions but not all; some courts use a multiplier of economic damages instead.
  • Non-economic damage caps vary widely by state (e.g., California MICRA cap, Texas Tex. Civ. Prac. & Rem. Code § 74.301).
  • Comparative fault rules follow the Restatement (Third) of Torts: Apportionment of Liability and state statutes.
  • Punitive damages, statutory damages, and attorney's fees are excluded from this estimate.
  • This tool does not constitute legal advice. Consult a licensed attorney for case-specific guidance.
