Two methods, one goal
The two standard methods are the multiplier method and the per-diem method. The multiplier takes your total medical bills and multiplies by a factor between 1.5 and 5, set by injury severity. The per-diem assigns a daily dollar value to your suffering and multiplies by recovery days. Both are negotiating anchors, not court formulas, and this page walks through each one with a worked number.
Method 1: the multiplier method
Add all injury-related medical expenses: hospital, surgery, physical therapy, medication. Multiply by a factor reflecting injury severity, typically 1.5 for minor soft-tissue claims and up to 4 or 5 for severe, permanent injuries. On $20,000 in medical bills with a multiplier of 3, pain and suffering comes to $60,000. Adjusters and attorneys weigh permanence, recovery duration, documented emotional distress, and how clear liability is when they pick a number inside that range. See the multiplier method explained for the full breakdown.
Method 2: the per-diem method
Assign a daily value to your suffering, typically your actual daily wage, which is easy to document, or a self-chosen flat rate with no verified public benchmark. Multiply by the days from the accident to maximum medical improvement (MMI). At $250 a day over a 90-day recovery, that is $22,500. See the per-diem method explained for how to pick and justify a daily rate.
Which method gives a higher number?
It depends on the facts. Short recoveries with large medical bills tend to favor the multiplier. Long, painful recoveries with modest medical costs often favor the per-diem. Attorneys routinely calculate both and lead with whichever produces the stronger result.
Non-economic damages beyond pain and suffering
Pain and suffering is the largest non-economic category, but a complete claim can also include loss of enjoyment of life, loss of consortium, and emotional distress. These are argued separately, though they tend to influence what multiplier gets applied. The injury claim calculator shows your total economic and non-economic estimate in one place.
These are estimates, not guarantees
Both methods produce a starting point for negotiation. Actual settlements depend on liability, the at-fault policy limits, available evidence, and how each side is represented. Consult a personal injury attorney before accepting any offer.
