Loss of Wage-Earning Capacity (LWEC) Center

When an accepted work injury leaves an employee able to work—but not necessarily able to earn what the employee could have earned without the injury—OWCP may determine wage-earning capacity. That determination can be based on actual earnings or, when appropriate, a constructed position.

Where LWEC Fits

01ACCEPTED INJURYThe employee has an accepted FECA condition.
02WORK CAPACITYMedical evidence shows some ability to work.
03EARNING CAPACITYOWCP evaluates what the employee can earn in the disabled condition.
04ACTUAL OR CONSTRUCTEDCapacity is measured from representative earnings or a suitable available position.
05SHADRICKThe statutory wage-loss relationship is converted into compensation.
06FORMAL LWECA formal decision can have continuing consequences if later wage loss occurs.
TWO METHODS

Actual Earnings vs. Constructed Position

5 U.S.C. § 8115(a)

Actual Earnings

FECA directs OWCP to use actual earnings when those earnings fairly and reasonably represent the employee's wage-earning capacity.

  • Actual wages are generally the best measure of earning capacity.
  • The position must fairly and reasonably represent the employee's capacity—not merely be a temporary or make-shift arrangement that distorts it.
  • Current OWCP procedure states a formal actual-earnings LWEC decision cannot be issued until the employee has completed 60 days of employment.
WHEN ACTUAL EARNINGS DO NOT CONTROL

Constructed Position

If actual earnings do not fairly and reasonably represent capacity—or the employee has no actual earnings—OWCP may determine capacity from a medically and vocationally suitable position that is reasonably available.

  • The employee does not necessarily have to be working in the selected position.
  • Medical suitability and vocational suitability both matter.
  • Labor-market evidence is used to address reasonable availability and wages.
ACTUAL-EARNINGS LWEC

Working Does Not Automatically Equal a Formal LWEC

The key question is whether the actual earnings fairly and reasonably represent wage-earning capacity. OWCP reviews the nature and stability of the employment and whether the earnings are a realistic measure of what the injured employee can earn.

At Least 60 Days

Current OWCP procedure says a formal actual-earnings LWEC decision cannot be issued until the employee has completed 60 days of employment.

Representative Work

The job should not be an odd-lot, temporary, seasonal, or make-shift position that fails to represent the employee's real earning capacity under the governing rules.

Partial Wage Loss

If representative post-injury earnings are lower than the appropriate pre-injury earning measure, FECA partial-disability compensation can address the injury-related loss.

When OWCP Determines What the Employee Could Earn

Section 8115 identifies factors OWCP must consider when actual earnings do not fairly and reasonably represent capacity or there are no actual earnings.

Nature of InjuryThe accepted injury and its continuing effects.
Physical ImpairmentThe degree of impairment and medically supported work capacity.
Usual EmploymentThe employee's previous type of work and occupational background.
AgeAge is one of the statutory factors considered.
QualificationsEducation, skills, experience, and qualifications for other employment.
Suitable EmploymentWhether appropriate work is reasonably available.
Other CircumstancesOther factors affecting earning capacity in the employee's disabled condition.
Labor MarketVocational rehabilitation research helps identify suitable, reasonably available target work and projected earnings.
THE SHADRICK FORMULA

LWEC Is About Capacity—not Simply Subtracting Two Paychecks

The Basic Logic

OWCP first expresses post-injury wage-earning capacity as a percentage by comparing post-injury earnings or constructed earnings with the current pay rate of the date-of-injury job. That percentage is then applied to the pay rate at the time of injury to determine the compensable loss, followed by the applicable FECA compensation rate and adjustments. This is commonly called the Shadrick formula.

This matters because a simple “old salary minus new salary” calculation can produce the wrong answer. The formula accounts for changes in the current pay of the date-of-injury position before determining the percentage loss of earning capacity.

VOCATIONAL REHABILITATION

Constructed Capacity Often Grows Out of Vocational Evidence

If return to the previous employer is unsuccessful, vocational rehabilitation may identify target occupations consistent with the employee's medical capacity, skills, education and experience. Labor-market information is then used to address whether suitable jobs are reasonably available and what they pay.

RETURN TO WORK / REHAB
01MEDICAL CAPACITYDefine reliable work restrictions.
02VOCATIONAL CAPACITYIdentify skills, education, experience, and transferable abilities.
03TARGET JOBSelect work that is medically and vocationally suitable.
04LABOR MARKETDetermine reasonable availability and projected earnings.
AFTER A FORMAL LWEC DECISION

Later Wage Loss Does Not Automatically Erase the LWEC

A formal LWEC determination has continuing significance. When circumstances later change, OWCP may need to decide whether the existing LWEC should be modified rather than treating the situation as an ordinary recurrence.

Original Rating Was Erroneous

Modification may be considered when the original LWEC determination is shown to have been in error.

Injury-Related Condition Changed

A material change in the injury-related condition can support reevaluation when it affects the basis of the established earning capacity.

MEDICAL EVIDENCE

Vocational Rehabilitation

Subsequent vocational rehabilitation can change the employee's demonstrated earning capacity and may support modification under OWCP procedure.

Why This Connects to Our Recurrence Center

If an employee with a formal LWEC later stops work or loses earnings, the first question should not automatically be “Is this a recurrence?” The existing LWEC decision must be identified because the correct procedural analysis may be modification of the LWEC determination.

LWEC VS. SUITABLE WORK

Related—but Different

SUITABLE WORK

Must the Employee Accept This Job?

The suitable-work process under §8106(c) focuses on an offer of employment and the consequences of refusing suitable work.

LWEC

What Is the Employee's Capacity to Earn?

Section 8115 focuses on measuring earning capacity for partial-disability compensation, using representative actual earnings or an appropriate constructed position.

Educational Resource: LWEC determinations can have long-term effects on FECA compensation. The actual decision, accepted conditions, medical work capacity, earnings history, vocational evidence, labor-market information, and current OWCP procedures control the result in an individual case.
