This is Part 5 of 8 in The Macro & Investing Playbook — a plain-English series that builds from the big picture (economies and cycles) down to the practical (reading a company, building a portfolio). This is where we zoom from the macro down to a single company.
A photo, not a video
So far this series has been about the whole economy — cycles, sectors, rates. Now we go granular: how do you tell whether one company is financially healthy? The answer lives in three financial statements, and the most misunderstood of them is the balance sheet.
Here's the single most useful way to picture it. A balance sheet is a photo — it captures exactly what a company owns and owes on one specific date. The income statement, by contrast, is a video: it shows how the company performed over a period (a quarter, a year). Both matter, but they answer different questions. A photo tells you the company's financial position right now; the video tells you how it got there.
Make it personal. Your own assets — your house, your car, your savings — minus your liabilities — your mortgage, your loans — equal your net worth. A company's balance sheet is the same idea, and that net-worth line has a name: equity.
The one equation that never breaks
Everything on a balance sheet flows from a single rule:
Assets = Liabilities + Shareholders' Equity
It always balances — that's why it's called a balance sheet. Everything a company owns (assets) was funded either by borrowing (liabilities) or by its owners (equity). Money had to come from somewhere.
That's the whole secret. If a company owns a $10 million factory, it either borrowed money to buy it, or its owners put up the cash — or some mix. The two sides can't drift apart. Once you internalise this, the rest is just learning what fills in each side.
The Macro & Investing Playbook
The full 8-part series, in order:
The left side: what the company owns (assets)
Assets are split by how quickly they can turn into cash. The dividing line is one year.
Current assets (cash within a year)
- Cash & equivalents — the most liquid thing there is. Money in the bank, plus near-cash holdings.
- Accounts receivable — money customers owe the company for goods or services already delivered but not yet paid for.
- Inventory — goods waiting to be sold, plus raw materials and work in progress.
Non-current assets (the long-haul stuff)
- Property, plant & equipment (PP&E) — factories, machines, buildings, land. This is usually shown net of depreciation, meaning the original cost minus the wear-and-tear that has been written off over time.
- Intangibles and goodwill — things you can't touch. Goodwill deserves special attention: it appears when a company buys another business for more than the fair value of that business's net assets. It is an accounting placeholder, not a hard, sellable asset — you can't auction off goodwill if times get tough.
The right side: what the company owes, and to whom
The right side mirrors the left: it's also split by the one-year line, then capped off with what belongs to the owners.
Current liabilities (due within a year)
- Accounts payable — money the company owes its own suppliers.
- Short-term / notes payable — near-term borrowings.
- Current portion of long-term debt — the slice of a long-term loan that comes due in the next twelve months.
Non-current liabilities (the long-term debts)
- Long-term debt and bonds payable — borrowings due more than a year out.
Shareholders' equity (what's left for the owners)
Equity is what would remain for owners if every asset were sold and every debt repaid. It has two main parts:
- Paid-in / share capital — the money shareholders originally invested when they bought shares from the company.
- Retained earnings — the cumulative profit the company has kept over its lifetime rather than paying out as dividends. This is how a healthy company grows its own net worth from the inside.
Why one statement is never enough
The balance sheet doesn't stand alone. The three financial statements are stitched together:
- Net income from the income statement flows into retained earnings on the balance sheet — profit the company keeps lands here.
- The cash-flow statement reconciles to the cash line on the balance sheet — it explains how the cash figure actually moved.
No single statement tells the whole story. A company can look profitable on the income statement and still be quietly running out of cash. That's why "it made a profit, so it's healthy" is one of the most expensive assumptions an investor can make. Read all three.
The handful of ratios that actually matter
You don't need dozens of metrics. A few, read together, tell you most of what you need. (None of these requires more than dividing one number by another.)
Can it pay its bills? (Liquidity)
- Working Capital = Current Assets − Current Liabilities. A dollar amount — the cushion left after near-term obligations. Positive is the baseline expectation.
- Current Ratio = Current Assets ÷ Current Liabilities. How many times over the company could cover its short-term bills with its short-term assets.
- Quick Ratio (acid-test) = (Current Assets − Inventory) ÷ Current Liabilities. The same idea, but stricter — it strips out inventory, because inventory can be slow or hard to sell in a pinch.
How much is borrowed? (Leverage)
- Debt-to-Equity = Total Liabilities (or Total Debt) ÷ Total Shareholders' Equity. How much the company leans on borrowed money versus owners' money.
- Interest Coverage = EBIT (operating income) ÷ Interest Expense. How comfortably profits cover the interest on the debt. This is the real test of whether debt is dangerous.
How well does it use owners' money? (Returns)
- Return on Equity (ROE) = Net Income ÷ Average Shareholders' Equity. The profit generated for every dollar of owners' capital.
- Book value per share = Shareholders' Equity ÷ shares outstanding. The accounting net worth attributable to each share.
What's "good" — and the giant asterisk
The ranges below are rough rules of thumb. The asterisk is enormous: healthy ratios are always industry-dependent. Compare a company to its peers, never to an abstract ideal.
| Ratio | Roughly healthy | Watch out |
|---|---|---|
| Current ratio | ~1.5 – 3.0 | Below 1 may not cover short-term bills; above 3 may mean cash sitting idle |
| Quick ratio | 1.0 or higher | Below 1.0 leans on selling inventory to pay bills |
| Debt-to-equity | Below 1.0 conservative; ~1–2 common | High is normal for banks, utilities, real estate, telecom; riskier for cyclical or tech firms |
| Return on equity | ~15%+ generally strong | Can be inflated by debt — read it alongside leverage |
| Interest coverage | Above 3x | Below 1.5x means profits barely cover the interest |
Red flags worth a second look
You don't have to be an auditor to spot trouble. Watch for:
- Steadily rising debt year after year, especially if profits aren't keeping pace.
- Negative or shrinking equity — the company's net worth is being eroded.
- Ballooning goodwill — a sign of overpriced acquisitions that may have to be written down later, hitting the books.
- Inventory or receivables growing faster than sales. This can mean unsold stock piling up, customers who aren't paying, or aggressive revenue recognition — none of them good.
Four myths that trip up beginners
Myth 1: "High debt is always bad."
Not true. Capital-intensive sectors — utilities, telecom, real estate, banks — safely carry high leverage because their cash flows are stable and predictable. What matters isn't the size of the debt but whether the company can service it, which is exactly what interest coverage measures. Always compare within the same industry. We touched on why some sectors are built this way in Part 2 on sector rotation.
Myth 2: "Book value equals market value."
No. Book value is the historical accounting cost of the company's net assets. The market price reflects something else entirely — expectations about the future, the strength of the brand, growth prospects. A great company can trade well above book value; a troubled one can trade below it.
Myth 3: "High ROE is always great."
ROE can be juiced. Loading up on debt or buying back shares both shrink the equity base, which mechanically lifts ROE without the underlying business getting any better. Always read ROE next to the debt picture.
Myth 4: "If it's profitable, it's healthy."
As noted above, a profitable company can still run out of cash — which is why you read all three statements, not just the bottom line of one.
The value-investing lens
If you take the balance sheet seriously, you're already thinking like a value investor. Benjamin Graham, in Chapter 20 of The Intelligent Investor, gave the discipline its core idea: the margin of safety. The principle is to buy a company with a strong balance sheet at a meaningful discount — roughly 30% — to your estimate of its intrinsic value. The gap is your protection against being wrong.
"Price is what you pay; value is what you get." — Warren Buffett, quoting Benjamin Graham
The balance sheet is where you start to gauge that value: a fortress balance sheet — manageable debt, real assets, growing retained earnings — is exactly the kind of business that survives the bad parts of the economic cycle we mapped earlier in this series.
Putting it to work
Next time you look at a company, you don't need a spreadsheet full of formulas. Run this quick mental pass:
- Does the equation make sense? Is equity positive and growing over time, or shrinking?
- Can it pay its bills? Glance at the current and quick ratios.
- Is the debt safe? Check debt-to-equity against its industry, then confirm with interest coverage.
- Any red flags? Rising debt, ballooning goodwill, inventory or receivables outpacing sales.
That's reading a balance sheet — no accounting degree required. With a sense of how to judge a single company, the natural next question is what most people should actually do with that knowledge. For the majority of investors, the honest answer is delightfully boring, and that's the subject of Part 6 on lazy investing that actually wins.
