The multiplier method: scaling off your damages
The multiplier method is the industry's default approach. It takes your economic damages — medical bills and lost wages — and multiplies that total by a factor generally between 1.5 and 5, chosen based on injury severity, recovery time, and whether any permanent impairment is involved.
The per diem method: valuing each day
The per diem (Latin for "per day") method works differently. It assigns a specific dollar value to a single day of pain and suffering and multiplies that rate by the total number of days of documented recovery, tying the value directly to time rather than to the size of your medical bills.
Why the defendant's identity overshadows both methods here
Pennsylvania's constitution bars capping damages against a private defendant entirely — confirmed by the Pennsylvania Supreme Court in 2014. But a claim against a government agency faces a real dollar ceiling: $500,000 for a local agency, $250,000 for a state agency. Against that backdrop, whether a 2x or 4x multiplier is used matters far less than whether the defendant happens to be private or governmental.
So identifying the defendant type comes first
Before investing effort in choosing between the multiplier and per diem methods for a Pennsylvania claim, it's worth confirming whether any defendant involved is a government entity — that classification can determine whether a ceiling applies at all, a far bigger factor than either valuation method would be.
Neither is required by Pennsylvania law
Both methods remain negotiating tools, not a formula Pennsylvania courts are required to apply. A jury retains discretion to award whatever amount it finds appropriate for noneconomic damages — subject only to the sovereign immunity cap when a government entity is the defendant.
