Human Capital: Your Earning Power Is Your Biggest Asset
I'm Andy Temte and welcome to Money Lessons! Join me every Saturday morning for bite-sized lessons that are designed to improve financial literacy around the world. Today is October 10, 2026.
Over the last four Saturdays we sized up a year of pay — the pay stub, the income tax, the benefits, and last Saturday the self-employed person who has no employer to do any of that. Back on August 8th, in the first episode of this series, we named the six jobs your money has — earn, spend, borrow, protect, grow, and give — and we said that the first job, earn, covers two things: the size of what flows in today and, just as important, how that amount increases over your working life. I closed last Saturday by naming today's topic — human capital, the skills and earning power that are the largest asset most people will ever own — so today we'll define that asset, measure how large it is, and I'll be precise about why I called building it the highest-return investment available to you.
Three Terms We Need
Let's start with three definitions.
The first term is human capital. In economics, capital is anything you own that produces income over time: a factory, a rental house, a savings account that pays interest. Human capital is the capital you carry around inside you. Back on February 1st of last year, we said that competence is a portfolio of knowledge, skills, abilities, and attitudes. Your human capital is that competence, plus the experience you've built and the health that lets you show up and use it — put simply, everything about you that an employer or a customer will pay for. You build it with schooling, with training, and with years on the job.
Fun fact, the economist who made the term famous nearly didn't use it. Gary Becker published a book called Human Capital in 1964. Becker counted schooling, training, and even medical care as capital, because each one improves health or raises earnings over a lifetime. Years later he wrote that he had hesitated over that title, because critics at the time believed the phrase treated people like slaves or machines. So he hedged and gave the book a long subtitle: A Theoretical and Empirical Analysis, with Special Reference to Education.
The second term is earning power. Your earning power is the pay your human capital can command right now — the salary or the hourly wage someone will pay this year for what you know and can do.
The third term is lifetime earnings. Your lifetime earnings are the sum of every paycheck, and, when you work for yourself, every dollar of the net earnings we defined last Saturday, from today until the day you stop working. Earning power is this year's number; lifetime earnings are all the years put together.
With those three terms defined, let's measure the asset that is human capital.
The Asset That Isn't on Your Balance Sheet
On July 25th, in our episode on why to own stocks, we noted that for most middle-class households, the equity in their house — the part they own outright, free of the mortgage — is still the largest asset they have. Today we put home equity next to an even bigger asset.
But first, a reminder. Net worth is everything a family owns minus everything it owes. In the Federal Reserve's most recent survey of family finances, from 2022, the median family — the family right in the middle, with half of families above it and half below — had a net worth of $192,900. For the typical homeowner, the equity in their house is the largest piece of that net worth.
Now let's put lifetime earnings next to home equity. The Georgetown University Center on Education and the Workforce uses Census Bureau data to estimate what full-time workers earn from age 25 to age 64. For the median worker whose education stopped at a high school diploma, those forty years of work add up to about $1.6 million. For the median worker with a bachelor's degree, the total is about $2.8 million.
Note that the median family's net worth and the median worker's lifetime earnings measure different things, and an economist would not set them side by side as they stand. Net worth is a snapshot of what a family holds today. The $1.6 million in lifetime earnings for the high school graduate is forty years of future paychecks added together, and back on August 2nd of last year we introduced the time value of money: a dollar today is worth more than a dollar tomorrow. The correct comparison reduces those future paychecks to what they are worth today — their present value — before putting them next to home equity.
The World Bank does exactly that when it measures a country's wealth. It counts human capital as the present value of what the labor force will earn over its working life, and in its most recent accounting, for 2020, human capital was 60 percent of all the wealth in the world — more than every factory, building, machine, farm, forest, and mineral deposit put together — and its share generally rises as countries get richer. So even after future paychecks are reduced to their present value, for most working people the asset that produces their paychecks is larger than everything else they own, and no personal balance sheet — the list of what you own and what you owe — carries a line for it, because you can't sell it. That is what I meant last Saturday when I said that skills and earning power are the largest asset most people will ever own. And the gap between the high school graduate's $1.6 million and the college graduate's $2.8 million shows how much a credential can add to this asset; whether a particular credential is worth what it costs is a lesson of its own, in two weeks.
What Kind of Asset This Is
If human capital is an asset, it is an unusual one, and three of its properties matter for the rest of this series.
First, you can't sell your human capital, and when you leave a job, it leaves with you. A house can be foreclosed on and a car can be repossessed; your skills can't be.
Second, you can borrow against your human capital. A student loan is money borrowed today against earning power you expect to have later, which is what makes it different from a car loan or a credit card balance.
Third, human capital loses value if you don't maintain it. A skill you stop using fades, and a skill the world stops needing stops earning; either way, this asset needs upkeep.
Why a Raise Compounds
A little over a year ago, in the late summer of 2025, we spent three episodes on compounding, and we defined it as earning returns not just on your original investment, but also on all the returns you've earned in previous years — growth on growth.
A raise works the same way. Suppose your employer gives raises as a percentage of your pay. This year's raise is figured on a salary that already includes last year's raise. Next year's raise will be figured on a salary that includes this year's. Every raise you have ever earned is in the base that every future raise is applied to, so in most working lives a raise earned at 25 stays in your pay, and gets raised again, year after year until you retire. That is compounding in the strict sense — growth on growth — and it is why a skill that lifts your pay early in your career is worth more than the same skill learned late.
One caution, because not every skill compounds. A raise compounds only as long as the skill behind it keeps earning. Some skills are durable: the ability to write clearly, to explain a problem to someone outside your specialty, to run a meeting that ends with a decision. Communication was on our list of the ingredients to success back on February 1st of last year, and a skill like that compounds for a whole career. Other skills expire when technology or the way a business runs moves on; the ability to write in cursive, which schools once drilled for hours, is worth nearly nothing in a workplace today. Building skills early pays the most when the skills you build are the ones that last.
Now I want to be clear about something I said last Saturday. I called building your skills the highest-return investment available to you, and two earlier episodes could seem to argue against that. On September 13th of last year, we said that paying off a 22 percent credit card debt guarantees a 22 percent return on every dollar applied to the balance, and on September 26th that a common employer retirement plan match pays 50 cents for every dollar you contribute. Both of those are excellent returns, and both are capped: the card payoff ends when the balance reaches zero, and the match stops at the percentage written into the plan's formula. There is no formula that caps your earning power. So when I say highest return, I don't mean the highest rate; I mean the largest payoff in dollars that most people will ever earn from any investment they make.
What This Means for You
There are two things to focus on from today's episode.
First, you already own the largest asset you will ever own. You didn't buy it, you can't sell it, and it never appears on a personal balance sheet, but every working week you are either adding to it or letting it sit. On August 8th we said that managing your money is stewardship of your own small economy, held in trust for your future self and for the people who count on you. Your earning power is the first thing in that economy for you to steward.
Second, early matters. A lasting skill you build this year gets raised every year for the rest of your career; the same skill built ten years from now gets raised for ten fewer years. If you're in the middle of your working life, the same mechanism still works for you: a skill built at 45 gets raised every year until you retire. The window is shorter, not closed.
So here's your homework this week. Take your current annual pay and multiply it by the number of years until you plan to stop working. Write that number down, and keep it where you'll see it.
Your earning power is the biggest asset you own. Invest in it.
Next Saturday we take up work alignment: whether the work you're paid for fits the purpose you have, and what it costs you, in both monetary and non-monetary terms.
Until next week... Grace. Dignity. Compassion.
