How car accident settlements are calculated
An injury claim adds up two kinds of damages. Economic damages are losses with a receipt: medical bills, future medical care, lost wages and lost earning capacity, car repairs and other out-of-pocket costs. Non-economic damages cover pain, suffering, emotional distress, inconvenience and loss of enjoyment of life. Insurance adjusters put a number on the second part with one of two methods, and the calculator shows both.
The multiplier method
The adjuster multiplies your medical expenses by a number from 1.5 to 5 to value pain and suffering, then adds lost income and property damage on top. Multipliers of 1.5 to 3 are the most common. A higher multiplier is justified when the other driver was clearly at fault, the injuries are confirmed by doctors rather than only by you, treatment involved fractures or surgery, recovery took six months or more, or there are lasting effects. Only rare, catastrophic cases go above 5.
Example: $15,000 in medical bills with a moderate injury at 3× gives $45,000 for pain and suffering. Add the $15,000 in medical bills, $3,000 in lost wages and $4,000 in car repairs, and the claim is worth about $67,000 before any fault reduction or fees. That is the default example above.
The per diem method
Per diem means "per day". It assigns a daily amount for each day you lived with the injury, often your daily earnings. Someone earning $45,000 a year makes about $180 per working day (over 250 days); 150 days of recovery × $180 = $27,000 for pain and suffering. It works poorly for permanent injuries or when income is unusually low or high, which is why it is best used as a second opinion next to the multiplier. Courts in some states do not let lawyers argue a per diem figure to a jury.
How your share of fault changes the settlement
If you were partly to blame, your state's negligence rule decides how much you lose. A jury or adjuster assigns each side a percentage, and:
| Rule | What happens | States |
|---|---|---|
| Pure comparative fault | Your award drops by your percentage, even at 90% | Alaska, Arizona, California, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, New York, Rhode Island, Washington |
| Modified, 51% bar | Reduced by your share; barred if you are more than 50% at fault | Connecticut, Delaware, Florida, Hawaii, Illinois, Indiana, Iowa, Massachusetts, Minnesota, Montana, Nevada, New Hampshire, New Jersey, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Vermont, West Virginia, Wisconsin, Wyoming |
| Modified, 50% bar | Reduced by your share; barred at 50% or more | Arkansas, Colorado, Georgia, Idaho, Kansas, Maine, Nebraska, North Dakota, Tennessee, Utah |
| Contributory negligence | Any fault at all bars recovery | Alabama, District of Columbia, Maryland, North Carolina, Virginia |
| Michigan hybrid | Above 50% fault, economic damages are reduced and pain and suffering is barred | Michigan |
| Slight / gross negligence | Recovery only if your negligence was slight compared with the other side's | South Dakota |
Florida moved from pure comparative fault to the 51% bar in March 2023. In the District of Columbia, pedestrians and cyclists get a 51% bar instead of contributory negligence. Some sources count the states slightly differently, so confirm your state's rule with a local attorney.
Policy limits: the ceiling on most settlements
An insurer pays only up to the at-fault driver's bodily injury liability limit. Many states require just $25,000 per person and $50,000 per accident (written 25/50/25); California's minimum rose to 30/60/15 in 2025 and Texas requires 30/60/25. A judgment above the limit is often uncollectible unless the driver has assets or an umbrella policy. If your losses exceed the limit, your own underinsured motorist coverage may pay the difference. About 15% of drivers had no insurance in 2023, and one in three were uninsured or underinsured, according to the Insurance Research Council.
What comes out of your settlement
- Attorney fees. Personal injury lawyers usually work on contingency, typically one-third of the recovery, rising to about 40% if the case goes to litigation. The fee agreement must be in writing. Some states cap or schedule fees.
- Case costs such as medical records, expert reports and filing fees, deducted before or after the fee depending on your agreement.
- Medical liens. Health insurers, Medicare and Medicaid that paid your bills usually have to be repaid from the settlement. Medicare reduces its claim by a proportional share of attorney fees and costs.
The insured amount for a crash is often far below what a calculator shows. For context, the average auto bodily injury liability claim paid by insurers was $28,278 in 2024, according to Insurance Information Institute data.
Deadlines to file
Every state has a statute of limitations for injury lawsuits, from 1 to 6 years. California, Texas and Florida allow 2 years (Florida shortened its limit from 4 years for accidents after March 24, 2023), New York 3 years, and Louisiana moved from 1 to 2 years in July 2024. Tennessee allows only 1 year. Insurance claims usually have shorter notice requirements, so report the crash promptly.
Caps on pain and suffering
A few states cap non-economic damages in ordinary injury cases, including Alaska, Colorado, Idaho, Maryland, Mississippi, Ohio, Oklahoma and Tennessee. Most caps you hear about apply only to medical malpractice. In no-fault states you can sue for pain and suffering only after a serious injury (New York, New Jersey, Pennsylvania, Michigan and Florida) or once medical costs pass a dollar threshold (for example Hawaii, Kansas, Massachusetts and Minnesota).
Is a personal injury settlement taxable?
Under IRS rules, compensation for physical injuries or physical sickness is generally not taxable income, including the pain and suffering part. Interest, punitive damages, and emotional distress awards not tied to a physical injury are taxable, as are amounts for medical expenses you already deducted in an earlier year.
Slip and fall and workers' compensation claims
A slip and fall claim uses the same damages math, but you also have to show the property owner knew or should have known about the hazard and failed to fix it or warn you. Workers' compensation is different: there is no pain and suffering award, and wage benefits follow a formula, often two-thirds of your average weekly wage, so this calculator does not apply.
