The two methods
Multiplier: pain and suffering = medical bills × a number from about 1.5 to 5. It is quick, ties the value to documented treatment, and is what most adjusters reach for first.
Per diem: pain and suffering = a daily rate × days from the accident until you recovered or reached maximum medical improvement. It suits injuries with modest bills but a long, painful recovery.
Neither is binding. They give you a defensible opening figure and a way to test an insurer's offer.
Choosing a multiplier
| Injury | Multiplier |
|---|---|
| Minor: soft tissue, healed within weeks | 1.5 to 2 |
| Moderate: months of treatment, full recovery | 2 to 3 |
| Serious: fracture, surgery or long recovery | 3 to 4 |
| Severe: permanent injury or disability | 4 to 5 |
Push toward the high end for things a jury would feel strongly about: a permanent limp or scar, surgery, a long time off work, an injury that ended a hobby or sport, or a clearly reckless driver such as a drunk driver. Gaps in treatment, a slow return to the doctor and preexisting conditions push it down.
Per diem rate
The daily rate is usually your daily earnings before taxes: yearly pay divided by 260 workdays. Count calendar days, not workdays, from the accident to the date your doctor released you or said you reached maximum improvement. For a permanent injury the per diem method stops working, because there is no end date; use the multiplier.
Worked example
A neck and shoulder injury needs four months of physical therapy, with $9,000 in medical bills. The injured person earns $52,000 a year.
- Multiplier method at 2.5 (moderate injury): $9,000 × 2.5 = $22,500
- Per diem method: $52,000 ÷ 260 = $200 a day × 120 days = $24,000
The two methods land close together, which makes $22,500 to $24,000 a reasonable range to negotiate from.
What the law says
Courts do not use a formula. Jury instructions describe noneconomic damages and leave the amount to the jury's judgment, for example:
- California: jurors are told that no fixed standard exists for these damages and that they must use their judgment to decide a reasonable amount based on the evidence and common sense. (CACI No. 3905A (2026 edition))
- Florida: there is no exact standard for measuring pain and suffering, disability, mental anguish and loss of enjoyment of life; the amount should be fair and just in light of the evidence. (Fla. Std. Jury Instr. (Civ.) 501.2)
- New Jersey: the law provides no table, schedule or formula for measuring pain and suffering in money; the amount is left to the jury. A separate court rule lets lawyers suggest a per day (time-unit) calculation as argument only. (Model Civil Jury Charge 8.11E; N.J. Court Rule 1:7-1(b))
State caps
These states limit noneconomic damages in ordinary personal injury cases. The calculator warns you when one applies.
- Alaska: Greater of $400,000 or $8,000 x injured person's life expectancy in years; for severe permanent physical impairment or severe disfigurement, greater of $1,000,000 or $25,000 x life expectancy (AS 09.17.010)
- Colorado: $1,500,000 for civil actions filed in 2025 or claims accruing on or after Jan 1, 2025 (excludes medical malpractice and wrongful death, which have separate caps), to be inflation-adjusted Jan 1, 2028 and every 2 years. Earlier claims: $250,000 (court may raise to $500,000 on clear and convincing evidence), CPI-adjusted; for claims accruing Jan 1, 2024 to Dec 31, 2024 the adjusted figure is $729,790 (max $1,459,600).
- Idaho: Base cap of $250,000 (2003), adjusted every July 1 by the change in the state average annual wage. It does not apply to willful or reckless misconduct or to acts found beyond a reasonable doubt to be a felony.
- Maryland: Cap applies to all personal injury and wrongful death actions: $500,000 for causes of action arising on or after Oct 1, 1994, increasing $15,000 every Oct 1 ($965,000 for causes arising Oct 1, 2025 to Sep 30, 2026; $980,000 from Oct 1, 2026). Wrongful death with 2+ beneficiaries: 150% of the cap.
- Mississippi: $1,000,000 cap on noneconomic damages in civil actions filed on or after Sept 1, 2004, other than medical malpractice (med mal cap $500,000).
- Ohio: Greater of $250,000 or 3 times economic loss, up to a maximum of $350,000 per plaintiff or $500,000 per occurrence. No cap for catastrophic injuries: permanent and substantial physical deformity, loss of use of a limb, loss of a bodily organ system, or permanent physical functional injury preventing independent self-care
- Oklahoma: $500,000 per plaintiff for bodily injury claims (injuries on or after Sept 1, 2025); $1,000,000 for permanent mental injury that severely impairs employment or living standard; no cap for permanent and severe physical injury (substantial disfigurement, loss of use of a limb, loss or impairment of a major organ or system, or inability to care for self), or where the defendant was reckless, grossly negligent, fraudulent, or intentional/malicious
- Tennessee: $750,000 per injured plaintiff for all injuries and occurrences; $1,000,000 for catastrophic loss or injury (e.g. paraplegia, quadriplegia, amputations, serious burns, wrongful death of a parent leaving a minor child); no cap where the defendant had specific intent to inflict serious injury, was intoxicated, or committed a felony causing the injury
Frequently asked questions
How do insurance companies calculate pain and suffering?
Most adjusters start from the medical bills and multiply them by a factor, typically 1.5 to 5 depending on how serious and lasting the injury is. The diagnosis, the treatment and how long recovery took drive where in that range a claim lands, and the number is then negotiated.
What is the per diem method?
It puts a daily price on pain and suffering, often your daily earnings on the idea that living with the injury is at least as hard as a day at work, and multiplies it by the number of days from the accident until you reached maximum recovery.
Is there a legal formula for pain and suffering?
No. Juries are instructed that there is no fixed standard and that they should award an amount that is reasonable based on the evidence. Multipliers and per diem rates are negotiating tools, not law.
Do states cap pain and suffering damages?
A few do for ordinary injury cases: Alaska, Colorado, Idaho, Maryland, Mississippi, Ohio, Oklahoma, Tennessee. Many more cap noneconomic damages only in medical malpractice cases, which this site does not cover.
Is pain and suffering money taxable?
Not when it comes from a physical injury. Federal law excludes damages received on account of personal physical injuries from income. See are car accident settlements taxable.
