What Does Someone's “Earning Capacity” Actually Mean?
If someone earned $35,000 last year, does that mean their earning capacity is $35,000?
Not necessarily.
What if that person previously earned $80,000, holds a professional degree, has years of experience, and is currently working only part-time? What if someone earned $150,000 several years ago but has since experienced significant changes in their health, occupation, qualifications, or local labor market? Is $150,000 still a reasonable estimate of what they could earn today?
Those are very different situations, and they illustrate why actual earnings and earning capacity are not necessarily the same thing.
This distinction becomes particularly important in divorce and other legal matters where someone's ability to earn income may be relevant. A tax return can tell us what a person earned. A paystub can tell us what they are earning now. Neither document, by itself, necessarily tells us what that individual is reasonably capable of earning.
That requires a broader vocational analysis.
Income Is the Starting Point, Not Always the Answer
When I'm evaluating earning capacity, employment and earnings history are obviously important. I want to know where the person has worked, what positions they have held, how long they remained in those positions, whether they worked full-time or part-time, and how they were compensated.
But I don't stop there.
Imagine someone who historically earned $70,000 to $90,000 per year in a professional occupation but currently reports earning $30,000. There may be completely legitimate reasons for that difference. Perhaps the person's industry changed. Maybe they relocated. Perhaps their credentials expired, their availability changed, or a medical condition now limits the work they can perform. They may have left the workforce for several years and no longer possess current skills that employers expect.
On the other hand, the current income could reflect a voluntary reduction in hours, a career change, self-employment that is still developing, or work that does not make full use of the person's education and experience.
The number alone doesn't explain why the number changed.
That's what the evaluation has to investigate.
Earning Capacity Is About More Than What Someone Earned Before
Past earnings are valuable evidence, but they aren't automatically a prediction of future earnings.
Suppose someone earned $120,000 ten years ago in an occupation that has since declined significantly. It would be difficult to justify a present earning capacity of $120,000 solely because that salary appears on an old W-2.
The opposite can also be true. Someone who earned relatively little earlier in life may have since completed a degree, obtained professional credentials, accumulated experience, or developed skills that now qualify them for substantially higher-paying employment.
A vocational earning-capacity analysis therefore looks at the person's history while also asking a more current question:
What does this individual bring to today's labor market?
That distinction matters because earning capacity is not supposed to be a historical trophy case containing the highest salary someone ever earned. Nor should it simply mirror whatever income happens to appear on the most recent tax return.
The analysis has to connect the individual's vocational profile to realistic employment opportunities in the present labor market.
Education, Credentials, and Experience Matter
Education can significantly affect occupational options, but even this requires context.
Having a bachelor's degree, master's degree, professional license, certification, or specialized training may qualify someone for occupations that would otherwise be unavailable. The field of study matters. So does the age of the education, whether credentials remain active, and whether the individual has actually used that training professionally.
Experience matters for the same reason.
Someone who has spent fifteen years performing purchasing, sales, project coordination, design, management, bookkeeping, or administrative work may have developed skills that transfer to other occupations—even if their exact previous job is no longer realistic.
This is where transferable skills analysis becomes useful.
Instead of asking only, “Can this person return to the exact job they had before?” we can ask, “What other occupations make use of the skills they have already developed?”
That can substantially change the analysis.
The Labor Market Has to Be Real
This is one of the most important pieces of an earning-capacity evaluation.
It isn't enough to identify an occupation that theoretically fits someone's background. That occupation also has to exist in the person's relevant labor market.
If I conclude that someone could work as a particular type of professional, I want to know whether employers are actually hiring for that occupation. I want to know what qualifications those employers are requesting, where the jobs are located, whether the positions are full-time or part-time, and what employers are paying.
This is where a labor market survey becomes particularly valuable.
A labor market survey connects the person on paper to the employment market outside the evaluation room. Current job postings, occupational wage data, employer requirements, geographic availability, and other labor-market information help determine whether an occupational option is merely conceivable or genuinely realistic.
That difference is critical.
You can find an occupation in a database that appears to pay $100,000 per year. That does not mean the individual being evaluated can walk into the local labor market tomorrow and reasonably expect to earn $100,000.
The analysis has to go further.
A Salary Range Isn't the Same as an Individual Earning Capacity
Occupational wage data often provide a range of earnings. Depending on the occupation and source, that range can be quite broad.
Consider an occupation with reported wages between approximately $45,000 and $110,000 per year. It would be tempting to simply select the midpoint and call that someone's earning capacity.
But why the midpoint?
A person with little relevant experience may reasonably enter toward the lower portion of the range. Someone with years of directly related experience, current credentials, and a history of comparable earnings may warrant consideration further into the range. Geographic differences, industry, hours, commission structures, and other factors can also affect compensation.
The evaluator has to explain why the available evidence supports a particular conclusion.
Otherwise, the wage figure is just a number.
What About Someone Who Chooses to Work Part-Time?
This can become particularly important in family-law matters.
A person may currently work 20 hours per week even though they have historically worked full-time. Their present income therefore tells us what they earn under a 20-hour schedule, but it doesn't necessarily tell us what they could earn if they worked 40 hours.
At the same time, an evaluator should not automatically assume that everyone working part-time is capable of full-time employment.
There may be legitimate reasons for reduced availability, including documented medical limitations, caregiving responsibilities, disability-related restrictions, or other circumstances relevant to the case.
The evaluator's role is not to decide what someone should do with their life. It is to examine the available information and determine what employment and earnings appear vocationally realistic under the circumstances being evaluated.
Sometimes presenting more than one scenario is the most informative approach. For example, an analysis might consider estimated earnings under a part-time schedule and separately calculate what those same occupational wages would produce under full-time employment.
That allows the numbers to remain transparent rather than hiding assumptions inside a single figure.
Earning Capacity Isn't About Finding the Highest Possible Salary
This point deserves particular emphasis.
An earning-capacity evaluation should not be a search for the highest-paying occupation that can somehow be connected to someone's background.
If an individual has a degree in business, that doesn't mean every six-figure management position requiring a business degree represents a realistic vocational option.
Similarly, someone who once owned a business isn't automatically qualified for every executive position. A person who worked in sales isn't automatically capable of earning the highest commission reported in that industry.
The analysis should be grounded in what is reasonably supported by the person's education, experience, transferable skills, qualifications, limitations, availability, and labor-market evidence.
In forensic work, objectivity matters more than producing a dramatic number.
The Same Principle Works in the Other Direction
Earning-capacity evaluations aren't inherently designed to prove that someone should be earning more money.
Sometimes the evidence supports the opposite conclusion.
A person may have previously earned a high income but no longer possess the same vocational capacity. Their occupation may have disappeared. A disability may now restrict their ability to perform essential job functions. Their credentials may no longer be valid. Their skills may have become outdated after a lengthy absence from the workforce.
A credible evaluation has to be willing to recognize those circumstances too.
If every evaluation performed for one side of a case conveniently produces the conclusion that side wanted, the evaluation stops looking like an evaluation and starts looking like advocacy.
Those are not the same thing.
So, What Does “Earning Capacity” Actually Mean?
In practical vocational terms, I think of earning capacity as an evidence-based estimate of what someone can reasonably be expected to earn based on the interaction between the individual and the labor market.
The individual brings education, experience, skills, credentials, abilities, limitations, work history, and availability. The labor market brings occupations, employers, qualification requirements, job openings, schedules, and wages.
Neither side of that equation should be evaluated in isolation.
That's why determining earning capacity involves considerably more than looking at someone's current paycheck or finding their highest previous salary.
The real question isn't simply:
“What does this person earn?”
It's:
“Given this person's vocational background and the employment opportunities realistically available to them, what are they capable of earning?”
Answering that question requires more than arithmetic.
It requires evidence.
