Assets: What you have
These are things that you own that have economic value. It’s things you could sell, spend, or use to make money for you. Some examples of assets are
- Cash in a checking or savings account
- Your house
- Your car
- Money someone owes you (yes, that’s an asset)
A useful test is asking yourself, “Could I convert this into money, or does it put money into my pocket?” If yes, it’s an asset.It’s also instructive to note what is not an asset: your salary. Your salary is income, but that’s a different thing entirely. Assets are what you have at a moment in time. Income is what flows to you over a stretch of time. The distinction matters because income is recorded in its own mini me report.
Liabilities: What you owe
A liability is a claim someone else has on your assets. It’s money you’re obligated to pay to someone else.
- Credit card balance
- Student loans
- Car loan
- The $40 you owe your brother.
Liabilities aren’t bad per se; you may take on liabilities so that you can increase your earning potential, or purchase assets that could lead to future economic gain. Liabilities aren’t just loans. If your rent is due on the 1st and it’s now the 8th and you haven't paid it yet, then it’s a liability. You have an obligation (your lease) to pay it.
Equity: What’s actually yours
When you subtract what you owe from what you have, you’re left with what is actually yours. This is your equity or, more commonly, your net worth.
Accountants express the relationship between these three things in the following equation.Assets = Liability + Equity This equation always balances. Let's use a concrete example. If you buy a house for $300,000 and you make a down payment of $50,000 and you get a mortgage to pay the rest, then your asset (the house) is worth $300,000, you take on a liability of $250,000 (the loan you took), and your equity in the home is $50,000
Meet Maya
Abstractions are slippery, so let's give them a person. Maya is 29, works as a nurse, and has never once looked at her finances this way.
Her assets
| Checking | $3,200 |
| Savings | $8,000 |
| Retirement (401k) | $24,000 |
| Car | $12,000 |
| Total assets | $47,200 |
Her liabilities
| Credit Card | $2,400 |
| Car loan | $9,600 |
| Student loans | $21,000 |
| Total liabilities | $33,000 |
Her equity: $47,200 − $33,000 = $14,200That's Maya's net worth. One number that accounts for everything she owns and everything she owes. It's a far more honest picture than the $3,200 she sees when she opens her banking app.
Four things Maya could do with $500
This is where the equation stops being a definition and starts being useful. Watch what happens to her net worth in four different scenarios.
She spends $500 on a weekend trip.
Savings drops to $7,500. Nothing else moves. Net worth: $13,700. Down $500. Money left, and nothing came back.
She pays $500 toward her credit card.
Savings drops to $7,500, and the credit card balance drops to $1,900. Assets down $500, liabilities down $500. Net worth: $14,200. Unchanged.
She gets a $500 bonus.
Checking rises to $3,700. No liability changes. Net worth: $14,700. Up $500.
She buys a $500 mattress on her credit card.
She now owns a mattress worth roughly $500, and owes $500 more. Assets up, liabilities up. Net worth: $14,200. Unchanged; the same thing that happened with the house, just smaller.Four transactions, the same $500, four different outcomes. That's what the equation buys you: the ability to tell the difference.
Three things almost everyone gets wrong
"Paying off debt makes me richer." As you just saw: it doesn't change your net worth at all. It's a swap: you trade an asset for the removal of a liability, and they cancel out. This doesn't make it a bad idea. Killing a 24% credit card balance means every future dollar of interest stays with you instead of going to the bank, which bends your net worth upward over time. But the moment you make the payment, you are exactly as wealthy as you were a second before."I make good money, so I'm doing fine." Income and net worth are separate measurements, and one does not imply the other. Somebody earning $200,000 with $340,000 of debt and no savings has a negative net worth. Somebody earning $52,000 who's been steadily accumulating for a decade may be well into the positive. Income is a flow. Net worth is a level. High flow with a hole in the bucket still leaves you with an empty bucket."Your car isn't a real asset." You'll hear this a lot online, and it's the right instinct wearing the wrong clothes. Maya's car is unambiguously an asset; she could sell it tomorrow for around $12,000. What people are reaching for is that it's a depreciating asset: it loses value every year, unlike her 401(k), which is meant to grow. Both facts belong on the balance sheet. The trick isn't pretending the car doesn't exist; it's seeing clearly which of your assets are working for you and which are quietly shrinking.
Where this is going
Maya's snapshot answers one question: where do I stand right now? That's a balance sheet, and it directly expresses Assets = Liabilities + Equity. But a snapshot can't tell you how you got here or where you're headed. That takes two more reports:
- An income statement asks: over the last month, did more value come in than went out? This is what actually moves your net worth from one balance sheet to the next.
- A cash flow statement asks: where did the physical money go? You can have a healthy net worth and still not make rent, because equity you can't easily reach isn't equity you can spend this Tuesday.
Three reports, three questions, one equation underneath them all. Because the equation has to stay balanced, every transaction you make shows up in at least two places, and that self-checking property is exactly why businesses have used this system for centuries. It's also why I built my app on real GAAP accounting rather than a simpler ledger: households aren't fundamentally different from small businesses, and they deserve books that can't quietly lie to them.
