## 1. Statutory Calculators & Mathematical Formulas

### 1.1 Car Accident Settlement Calculator
- Canonical Route: https://legalcalculator.online/car-accident-settlement
- Economic Special Damages Formula:
  Special Damages = Ambulance + Emergency ER + Diagnostic Imaging (MRI/CT) + Surgery + Physical Therapy + Chiropractic + Future Rehabilitation + Prescription Medication + Vehicle Repair/Total Loss Actual Cash Value (ACV) + Documented Lost Wages.
- General Non-Economic Damages (Multiplier Method):
  Pain and Suffering = Special Medical Damages * Multiplier (M)
  Where M is determined by injury severity:
  - Minor soft tissue / cervical sprain (4–6 weeks care): 1.5x to 2.0x
  - Moderate injuries (fractures, tears, epidural injections): 2.5x to 3.5x
  - Severe / Catastrophic (surgery, TBI, spinal cord, permanent impairment): 4.0x to 5.0x+
- Comparative Negligence Deductions:
  - Pure Comparative Fault (CA, NY, WA): Net Damages = Total Damages * (1 - Plaintiff Fault %)
  - Modified Comparative Fault 51% Bar (TX, FL, IL, PA, OH): If Plaintiff Fault >= 51%, Net Recovery = $0. If Plaintiff Fault < 51%, Net Recovery = Total Damages * (1 - Plaintiff Fault %).
  - Pure Contributory Negligence (VA, MD, NC, AL, DC): If Plaintiff Fault > 0%, Net Recovery = $0.
- Net Client Payout:
  Net Payout = (Gross Settlement * (1 - Comparative Fault %)) - Attorney Contingency Fee (33.3% pre-suit / 40% litigation) - Medical Liens / Subrogation (Medicare, Medicaid, ERISA health plans) - Case Costs.
