How to Read a Balance Sheet | How Do Stocks Work?

A balance sheet is a snapshot of what a company owns, what it owes, and what is left over for shareholders on a single date. It always balances because of one equation: assets = liabilities + shareholders’ equity.

In short: the balance sheet (formally the statement of financial position) lists a company’s assets (cash, receivables, inventory, equipment, investments), its liabilities (bills, debt, deferred revenue, other obligations) and the difference between them, shareholders’ equity, also called book value. Unlike the income statement, which covers a period, the balance sheet describes one moment, usually the last day of a quarter or fiscal year.

Why it always balances

Every asset a company holds was paid for in one of two ways: with money it owes to someone (a liability) or with money that belongs to its owners (equity). Owners’ money comes from shares the company sold and from profits it kept rather than paid out.

A tiny example. Maple Widgets Inc., a hypothetical company, starts with $100 of cash from selling shares. Its balance sheet: assets $100 = liabilities $0 + equity $100. It then borrows $60 and buys a $60 machine. Now assets are $160 ($100 cash plus a $60 machine) = liabilities $60 + equity $100. If it then earns $20 of profit in cash and keeps it, assets rise to $180 and equity to $120. Every transaction touches at least two lines, and the equation holds after each one.

The main sections

Assets

Current assets are expected to turn into cash or be used up within a year: cash and cash equivalents, short-term investments, accounts receivable (money customers owe), inventory, and prepaid expenses.
Non-current assets last longer: property, plant and equipment (PP&E, shown net of accumulated depreciation), long-term investments, goodwill and other intangible assets from acquisitions, and deferred tax assets.

Liabilities

Current liabilities are due within a year: accounts payable (bills owed to suppliers), accrued expenses, deferred revenue (cash received for goods or services not yet delivered), short-term borrowings, and the portion of long-term debt due in the next twelve months.
Non-current liabilities are due later: long-term debt, lease liabilities, pension obligations, and long-term tax liabilities.

Shareholders’ equity

Paid-in capital (common stock plus additional paid-in capital): money raised from issuing shares, plus the value of stock-based pay.
Retained earnings: cumulative profits kept in the business, minus dividends and, at many US companies, the cost of shares bought back and retired.
Accumulated other comprehensive income (AOCI): certain gains and losses, such as unrealized changes in some investments and currency translation, that skip the income statement.
Some companies also show treasury stock, shares repurchased but not retired, as a negative number.

A worked example: Apple at September 27, 2025

Here is a condensed version of Apple Inc.’s consolidated balance sheet at the end of its fiscal 2025, from its Form 10-K filed on October 31, 2025. Figures are in millions of US dollars. As with any example on this site, this is not a view on whether the stock is a good or bad buy.

Assets	Sep 27, 2025
Cash and cash equivalents	$35,934
Current marketable securities	$18,763
Accounts receivable, net	$39,777
Vendor non-trade receivables	$33,180
Inventories	$5,718
Other current assets	$14,585
Total current assets	$147,957
Non-current marketable securities	$77,723
Property, plant and equipment, net	$49,834
Other non-current assets	$83,727
Total assets	$359,241

Liabilities and equity	Sep 27, 2025
Accounts payable	$69,860
Other current liabilities	$66,387
Deferred revenue	$9,055
Commercial paper	$7,979
Term debt (current portion)	$12,350
Total current liabilities	$165,631
Term debt (non-current)	$78,328
Other non-current liabilities	$41,549
Total liabilities	$285,508
Common stock and additional paid-in capital	$93,568
Accumulated deficit	($14,264)
Accumulated other comprehensive loss	($5,571)
Total shareholders’ equity	$73,733
Total liabilities and equity	$359,241

Check the equation: $285,508 + $73,733 = $359,241. It balances, as it must.

Ratio 1: current ratio (short-term liquidity)

Current ratio = current assets ÷ current liabilities = $147,957 ÷ $165,631 = 0.89.

A ratio below 1 means current liabilities exceed current assets. For a company with thin cash and slow-paying customers, that can be a warning sign. For Apple it needs context: the company also held $77,723 million of non-current marketable securities, which are investments with maturities beyond a year, and its current liabilities include the “other current liabilities” line, whose makeup is broken out in the notes. The ratio is a starting question, not an answer.

Ratio 2: debt and net cash

Add up the interest-bearing borrowings: commercial paper $7,979 + current term debt $12,350 + non-current term debt $78,328 = $98,657 million of debt.

Now add up cash and investments: $35,934 + $18,763 + $77,723 = $132,420 million. Apple’s 10-K reports the same total, $132.4 billion, in its liquidity discussion.

Net cash = $132,420 minus $98,657 = $33,763 million. When debt exceeds cash, the difference is called net debt, and it is a key input when you value a stock with enterprise value.

Debt-to-equity = $98,657 ÷ $73,733 = 1.34. Total liabilities to total assets = $285,508 ÷ $359,241 = 79.5%.

Book value per share = shareholders’ equity ÷ shares outstanding. Apple reported 14,773,260 thousand shares outstanding at September 27, 2025, about 14.77 billion.

$73,733 million ÷ 14,773 million shares = about $4.99 per share.

Why the accumulated deficit is negative

Apple has been highly profitable for years, yet it shows an accumulated deficit of $14,264 million. That looks odd until you read the statement of shareholders’ equity, which rolls the figure forward for fiscal 2025:

Accumulated deficit	$ millions
Beginning balance	($19,154)
Plus net income	$112,010
Minus dividends declared	($15,413)
Minus stock withheld for employee award taxes	($1,655)
Minus common stock repurchased	($90,052)
Ending balance	($14,264)

Apple charges its share repurchases against this account. Over many years it has returned more cash through buybacks and dividends than it has accumulated in profits, which pushed the balance below zero. The stock splits and buybacks article explains why companies do this.

The general point: a negative or low equity figure can come from heavy losses, which is a problem, or from returning large amounts of cash to shareholders, which is a choice. The balance sheet alone cannot tell you which. The cash flow statement and the equity statement can.

Book value and market value are different things

Book value is an accounting figure built mostly from historical costs. Market value, or market capitalization, is the share price times shares outstanding: what investors are paying today. For a business whose main assets are brands, software, patents, or staff expertise, much of that value never appears on the balance sheet because it was built internally rather than bought. That is why many companies trade at many times their book value, and why the price-to-book ratio is more informative for banks and insurers, whose assets are mostly financial and carried closer to current value, than for software or consumer brands.

What can go wrong

Reading one date in isolation

A balance sheet is a single day. Companies can make it look tidier at quarter-end, for example by collecting receivables or delaying purchases. Compare at least two dates (the 10-K shows two) and watch the direction of travel.

Missing obligations that are not on the face of the sheet

Some commitments appear only in the notes. Apple’s 10-K, for example, discloses $13,308 million of unconditional purchase obligations with terms over a year that are off the balance sheet. Leases, pensions, legal contingencies and guarantees also live in the notes. Read the commitments and contingencies note.

Trusting asset values too much

Goodwill reflects what a company paid for acquisitions above the fair value of identifiable net assets. If an acquisition disappoints, the company may record an impairment, writing the asset down and taking a charge on the income statement. Inventory can become obsolete. Receivables can go unpaid. Assets are estimates, and some estimates are softer than others.

Ignoring the maturity of debt

Total debt matters, but so does when it comes due. A company with large borrowings maturing next year and little cash faces refinancing risk if credit markets tighten. The debt note in the 10-K gives the schedule.

Comparing across accounting frameworks without care

US companies report under US GAAP. Canadian public companies report under IFRS, where the statement is usually titled the “statement of financial position”, the order of sections often differs (many IFRS reporters list non-current assets first), and some measurement choices differ. Totals are comparable in spirit, but check definitions before comparing line by line.

The short version

The balance sheet shows what a company owns, what it owes, and the difference, on one date. Start by checking how much cash and debt it holds, how liabilities due in a year compare with assets that will turn into cash, and how equity has changed. Then read the notes, because the most important obligations are sometimes there rather than on the face of the statement. Pair it with the income statement and the cash flow statement for the full picture.
