Why a formal diagnosis changes the math
Claims adjusters draw a hard line between two things that sound similar. On one side is what lawyers call garden-variety emotional distress: the stress, poor sleep, and anxiety that follow almost any crash or fall, claimed without medical records to back it up. On the other side is PTSD as a diagnosis, a defined condition with specific criteria in the DSM-5, identified by a psychologist or psychiatrist and documented in a treatment record.
The first gets folded into a low multiplier. The second is evidence.
A diagnosis converts a subjective complaint into a medical fact an adjuster has to price. It comes with a named clinician who can testify, a treatment plan that shows the injury is real and ongoing, and billing records that grow the economic-damages base the multiplier applies to. That is why the calculator above adds 0.5 to the multiplier when PTSD is formally diagnosed: not because any rulebook says so, but because a documented psychiatric injury reliably supports arguing the upper end of the range. The multiplier and per diem methods both reward exactly this kind of documentation.
Three systems, three very different numbers
Where the PTSD came from decides which math applies, and the three main routes barely resemble each other.
Car accidents and other liability claims. This is the multiplier territory. PTSD after a serious crash is claimed against the at-fault party's insurer alongside physical injuries, and it raises the severity picture of the whole claim. Some states also allow stand-alone emotional-injury claims with no physical injury, but the rules (zone of danger, bystander recovery) vary enough that only a local attorney can say whether yours is viable.
Workers comp. Comp is a no-fault system that generally does not pay traditional pain and suffering, so the multiplier method does not apply. Mental-only claims, PTSD with no accompanying physical injury, are compensable in some states and excluded or tightly restricted in others, with first responders often covered under special provisions. If the trauma happened at work, that state-by-state question comes before any calculation.
VA disability. Not a settlement at all, but monthly compensation for as long as the rating holds. The VA rates PTSD under the General Rating Formula for Mental Disorders in 38 CFR 4.130 at one of six levels, based on how much the condition impairs work and social functioning.
2026 VA compensation by PTSD rating
These are the current rates for a veteran with no dependents, effective December 1, 2025, according to VA.gov. Dependents (a spouse, children, or dependent parents) raise the payment at ratings of 30 percent and above.
| PTSD rating | 2026 monthly rate | Impairment level (paraphrasing 38 CFR 4.130) |
|---|
| 0% | $0 | Diagnosed, but symptoms do not interfere with work or require continuous medication |
| 10% | $180.42 | Mild symptoms during periods of significant stress |
| 30% | $552.47 | Occasional decrease in work efficiency |
| 50% | $1,132.90 | Reduced reliability and productivity |
| 70% | $1,808.45 | Deficiencies in most areas: work, family, judgment, mood |
| 100% | $3,938.58 | Total occupational and social impairment |
Two things trip people up here. A 0 percent rating is not a denial; it means the VA accepts the condition is service connected, which preserves the claim for future increases and can matter for health care access. And the jumps between levels are steep, especially from 90 to 100 percent territory, which is why so much VA practice centers on the evidence for one rating level versus the next.
A worked example, injury-claim mode
Say a rear-end collision leaves someone with a diagnosed case of PTSD: panic behind the wheel, months of weekly therapy, a stretch of missed work. The file shows $9,500 in medical and therapy bills and $4,500 in lost wages, so $14,000 in economic damages. Moderate severity suggests a 3× multiplier; the formal diagnosis supports pushing to 3.5×.
$14,000 × 3.5 = $49,000 in estimated pain and suffering. Add back the economic damages and the estimated claim value is $63,000.
Now the part calculators usually skip. A contingency fee of 33 to 40 percent comes off the top, and therapy bills paid by health insurance may carry a lien against the settlement. That $63,000 estimate can net well under $40,000 in hand. Running the numbers both ways, and comparing against what a fair settlement looks like for claims of similar severity, is cheap insurance before anyone signs a release.
What actually moves the number
Three kinds of evidence do most of the work in a PTSD claim. The diagnosis itself, from a psychologist or psychiatrist rather than a self-report or a primary-care note in passing. The treatment history: consistent appointments, a followed treatment plan, and records that describe functional limits (cannot drive on highways, cannot sleep without medication) rather than just symptom labels. And for larger claims, expert testimony connecting the trauma to the event and projecting the future course of treatment.
Gaps hurt more than people expect. An adjuster reading a file with a three-month hole in therapy attendance will argue the condition resolved, whatever the claimant says later. Lay statements from family or coworkers who watched the change happen fill in the picture the clinical records cannot.
What this calculator cannot know
The multiplier model here is a negotiation convention, not a law, and no insurer is bound by it. The tool cannot see your state's rules on emotional-injury claims, comparative fault, damage caps, or the at-fault party's policy limits, any of which can move the real number far from the estimate. The VA figures are exact published rates, but the rating itself is the contested part, and this page cannot predict what rating an examiner will assign. For physical-injury math without the PTSD layer, the site's multiplier calculator and per diem calculator cover the standard cases.
