A comparison of the two ways injury claims get priced, the additive build-up against the multiplier rule of thumb, and what a first offer reveals about the adjuster's reserve.
Two people can look at the same crash file and produce numbers that differ by a factor of three, and neither of them is lying. The difference is method. One builds the claim from the documents up, line by line, and arrives at a figure that can be defended piece by piece if it ever has to be. The other takes the medical bills, picks a multiplier that feels right, adds a wage figure and calls it a demand. A careful reader can tell which method produced a number within about ten minutes of reading it.
The additive build-up, and what each line has to survive
The build-up starts with billed charges, then immediately separates them from what was actually paid and what remains owed, because those three numbers are rarely the same and the gap between them is where a lot of settlement value quietly disappears. Wage loss comes next, and it has to be provable: pay stubs, an employer letter with dates and rate, tax returns if the claimant is self-employed. Future care needs a treating physician willing to write it down. Everything that cannot be sourced to a document gets argued about, and arguing about it costs leverage on the parts that can be proved.
Pain and suffering sits on top of that base, but it is not calculated so much as justified. The support comes from duration of treatment, the type of treatment, whether there was surgery or injections rather than therapy alone, objective imaging findings, gaps in care, and how the injury shows up in ordinary life. A well-built demand ties each of those to a specific record, by date and provider. When an adjuster can trace the claim, the negotiation becomes about the value of proven facts rather than about whether the facts exist at all.
Why the multiplier shortcut misleads
The familiar rule, take the medical specials and multiply by something between one and a half and five, survives because it is easy and because it occasionally lands near the right answer. Its problem is that it treats the bill total as a proxy for harm, which rewards expensive treatment and punishes efficient treatment. Two months of chiropractic care can outbill a fracture that healed clean, and the multiplier will price the chiropractic claim higher. Adjusters know this, which is why a demand that visibly runs on the multiplier gets read as unserious before the medical summary is opened.
The shortcut also ignores everything that actually caps a case. Policy limits set a hard ceiling that no arithmetic gets past, and once the demand exceeds available coverage, the conversation shifts entirely to whether the defendant has other assets or other policies worth pursuing. Comparative fault then cuts whatever survives. In a state that reduces recovery by the claimant's share of blame, a well-documented hundred thousand dollar case with thirty percent fault attached is a seventy thousand dollar case, and the reduction applies before any lien is paid.
Reading the first offer for what it says about the reserve
Insurers set a reserve on a file early, a dollar amount held against the eventual payout, and the adjuster negotiates with that number in mind and limited authority around it. The first offer is almost never the reserve. What it signals is where the reserve sits relative to the demand, and the useful comparison is not the size of the offer but its structure. An offer that pays the billed specials and adds a token amount says the file is reserved near the documented economic loss. An offer well under the specials says liability or causation is in dispute, not damages.
The tell worth watching is the explanation that accompanies the number. When an adjuster cites a treatment gap, a prior claim, or a low-speed impact argument, they are telling you which line item they intend to attack, and that line item is usually the one holding the reserve down. Fix it with a physician's causation letter or an employer record, and the reserve can be revisited. The Bureau of Labor Statistics is the federal body that tracks earnings and employment across occupations, and wage loss claims move fastest when the claimed rate looks ordinary for the job.
The practical check on any settlement number is whether you could walk a stranger through it in five minutes using only paper already in the file. If a figure can be sourced, it can be defended, and defended figures are the ones that hold through the second and third rounds of a negotiation.
