Per Diem vs. Multiplier: The 2 Ways to Value Pain and Suffering
Pain and suffering is real, but it has no receipt. So how do you put a number on it? In practice, there are two accepted methods: the multiplier method and the per diem method. Insurers, attorneys, and juries use both. Knowing how each works — and which favors your case — is essential before you negotiate.
Method 1: The Multiplier Method
The most common approach. You take your economic damages (medical bills + lost wages) and multiply them by a number, typically between 1.5 and 5, based on injury severity.
Formula: (medical bills + lost wages) × multiplier = pain and suffering
Example: $16,000 in medical bills and lost wages, with a moderate soft-tissue injury and ongoing symptoms, at a 3× multiplier = $48,000 in pain and suffering. Total claim: $64,000.
What Determines the Multiplier
| Multiplier | When It Applies |
|---|---|
| 1.5–2× | Minor injury, full recovery, no lasting effects |
| 2–3× | Moderate soft-tissue, months of treatment |
| 3–4× | Injury with lasting symptoms or a procedure |
| 4–5× | Surgery, permanent impairment, major life impact |
| 5×+ | Catastrophic, disability, disfigurement |
Method 2: The Per Diem Method
Per diem is Latin for “per day.” You assign a daily dollar value to your suffering and multiply it by the number of days from injury to recovery.
Formula: daily rate × number of recovery days = pain and suffering
A common way to set the daily rate is to use your own daily earnings — the logic being that a day of pain is at least as burdensome as a day of work. If you earn $200/day and were affected for 180 days: $200 × 180 = $36,000.
When to Use Which
- Per diem works best for injuries with a clear start and end date and a full recovery — you can point to a defined number of suffering days.
- The multiplier works best for injuries with lasting or permanent effects, where “number of days” has no end and the severity is better captured by scaling economic damages.
- For serious injuries, neither method fully captures value. Attorneys in catastrophic cases anchor instead to published jury verdicts for comparable injuries.
The Reality: Insurers Use Software
Behind the scenes, most large insurers run your claim through valuation software (Colossus, Mitchell) that produces its own number. The multiplier and per diem methods are how you build and justify a counter-position — they give you a defensible framework to argue against the software’s output.
Do Not Forget the Non-Economic Categories
Both methods start from a single figure, but pain and suffering actually spans seven distinct categories — physical pain, mental anguish, loss of enjoyment, loss of consortium, disfigurement, inconvenience, and permanent impairment. Arguing each one that applies strengthens whichever method you use.
Our calculator uses a state-adjusted multiplier method as a starting point. Run your numbers, then use per diem as a cross-check for shorter-recovery injuries.
