Lost earning capacity Arizona claims get confused with lost wages constantly. Arizona law treats them as two separate elements of damages. Lost wages covers money you actually missed while recovering. Lost earning capacity covers something harder to see: a permanent reduction in your ability to earn going forward, even after you’ve returned to work.
The distinction Arizona law draws
The Revised Arizona Jury Instructions list these as separate elements. One covers lost earnings to date. The other covers any decrease in earning power or capacity in the future. The first is backward-looking and fairly simple to calculate. Pay stubs, tax returns, and time missed from work usually tell the story. The second is forward-looking and asks a harder question: has this injury permanently limited what you’re capable of earning for the rest of your working life?
A construction worker with a permanent back injury might return to a desk job at the same salary. Lost wages during recovery are easy to calculate in that case. But if the injury permanently closes off higher-paying physical trade work the person could have pursued, that’s lost earning capacity. It exists even without any current pay cut.
How lost earning capacity claims get proven
This category almost always requires expert testimony. A vocational rehabilitation expert typically evaluates what jobs and career paths remain realistically available given the injury, compared to what was available before. An economist then translates that gap into a dollar figure, factoring in projected career length, expected raises, and benefits.
Courts want reasonable certainty, not speculation. A vague claim that a worker “might have” advanced further carries little weight. A documented career trajectory carries much more: consistent raises, a clear promotion path, or a specific certification the injury now makes impossible to use.
Why both categories can apply together
Nothing prevents a claim from including both. Lost wages can cover the recovery period, while lost earning capacity covers the years beyond it. Each compensates a different time period and a different kind of loss. An attorney building a serious injury case typically evaluates both from the start, rather than treating wage loss as the whole earnings picture.
The bottom line
A paycheck that looks unchanged on paper can still hide a real, permanent loss. Lost earning capacity claims require more evidence than lost wages claims. For anyone facing a permanent injury, that evidence is often where the largest and most overlooked part of a case’s value actually sits.
