Loss of Earnings and Diminished Earning Capacity After an Injury

Lost earnings and diminished earning capacity are two separate types of damages in a personal injury case, and confusing the two can lead to an incomplete recovery.

Lost earnings cover the income a person has already missed because of an injury.

Diminished earning capacity covers the income a person is likely to lose in the future because the injury limits what kind of work they can do going forward.

Lost Earnings: Income Already Missed

Lost earnings are the more straightforward of the two categories.

This figure reflects the actual wages, salary, commissions, or self-employment income a person did not receive while recovering from an injury. Documentation typically includes pay stubs, tax returns, employer statements, and medical records showing the period during which a person was unable to work.

For hourly or salaried employees, this calculation is usually simple. For self-employed individuals or those who rely on commissions or seasonal work, the calculation often requires a closer look at prior years of income to establish a reliable baseline.

Diminished Earning Capacity: A Different Kind of Loss

Diminished earning capacity looks forward rather than backward. This category applies when a catastrophic injury permanently or long-term affects a person’s ability to earn the same income they could have earned before the injury, even after they return to work.

A construction worker who can no longer lift heavy materials, a nurse who can no longer stand for long shifts, or a driver who can no longer pass a physical exam for certain positions may all have a valid diminished earning capacity claim, separate from any wages already missed.

This type of damage does not require proof that a person is currently earning less. It requires evidence that the injury has reduced their capacity to earn in the future, even if they have not yet experienced that loss in a paycheck.

How These Losses Are Proven

Because diminished earning capacity involves predicting the future rather than documenting the past, it typically requires more than pay records. Cases involving this type of claim often rely on:

• Medical documentation describing the permanent nature of the injury and any resulting physical restrictions
• Vocational expert testimony addressing what jobs a person can realistically perform after the injury
• Economic or actuarial analysis projecting the income difference over the remainder of a person’s working life
• Evidence of the person’s education, training, skills, and work history before the injury

A single injury can support both a lost earnings claim and a diminished earning capacity claim at the same time, and the two figures are calculated separately before being combined into a total damages request.

Why Strong Documentation Matters to Adjusters

Insurance adjusters often push back harder on diminished earning capacity than on lost wages, since it relies on projections rather than pay stubs.

A well-documented claim, supported by medical and vocational evidence, gives an adjuster or a jury less room to dismiss the projected loss as speculation rather than a genuine, calculable harm.

This is another reason to gather vocational and medical evidence early, before memories fade and before an insurer has a chance to frame the injury as less limiting than it actually is.

Filing Deadlines in Kansas and Missouri

Both Kansas and Missouri recognize lost earnings and diminished earning capacity as separate, recoverable elements of damages in a personal injury case. Where the two states differ is in how much time an injured person has to bring a claim:

• In Missouri, most personal injury claims must be filed within five years of the injury under Mo. Rev. Stat. § 516.120.
• In Kansas, the general deadline is two years under K.S.A. § 60-513.

Because the underlying injury often has a lasting effect on a person’s ability to work, waiting to explore these claims can mean losing access to the evidence, such as employment records or witness recollection, needed to support a diminished earning capacity claim later.
