Compare Multiplier and Per Diem methods side-by-side. Adjust for comparative fault (Li v. Yellow Cab) and policy limits. No cap on PI non-economic damages.
The multiplier method calculates pain and suffering by multiplying your total special damages (medical bills, lost wages, property damage, out-of-pocket expenses) by a factor of 1.5x to 10x. The multiplier depends on injury severity, recovery time, impact on daily life, and whether there is permanent impairment. Most moderate PI cases use 2x-4x; severe cases with permanent injury may warrant 5x-10x.
The per diem (daily rate) method assigns a dollar value to each day you experience pain and suffering, then multiplies by the total recovery days. A common starting point is your daily earnings (e.g., $300/day for a $75K salary). For severe injuries, daily rates of $500-$1,000+ may be appropriate. This method works well when recovery duration is clearly documented.
For personal injury cases (car accidents, slip & fall, dog bites, etc.), California has NO statutory cap on non-economic damages. However, medical malpractice claims are subject to MICRA (AB 35), which caps non-economic damages at $350,000 for non-death cases and $500,000 for wrongful death (increasing annually by $50K through 2033, then 2% annually). The practical cap is usually the defendant's insurance policy limits.
Under Li v. Yellow Cab Co. (1975), California uses pure comparative fault. Your total damages (specials + pain and suffering) are reduced by your percentage of fault. Unlike modified comparative fault states, you can still recover even if you are more than 50% at fault. For example, at 40% fault with $200,000 in total damages, you receive $120,000.
Key factors that push the multiplier higher: (1) permanent impairment or disfigurement, (2) lengthy recovery period (6+ months), (3) need for surgery or hospitalization, (4) impact on daily activities and quality of life, (5) emotional/psychological harm (PTSD, anxiety, depression), (6) clear defendant liability, (7) defendant's egregious conduct, (8) strong documentation from treating physicians.
Under Howell v. Hamilton Meats & Provisions (2011), you can only recover the amount actually paid or incurred for medical care, not the higher "billed" amount. This means if a hospital billed $50,000 but accepted $15,000 from insurance, your special damages for that treatment are $15,000, not $50,000. This affects the multiplier method since it operates on actual paid amounts.
