How to read a balance sheet
What assets, liabilities and equity record, why the statement always balances, what working capital shows, and where book value stops describing a company.
Key points
- Assets equal liabilities plus equity, always. The statement is an identity, so it balances whether or not the business is healthy.
- It is a photograph on one date, not a record of a period, which is what separates it from the income and cash flow statements.
- Current assets and liabilities fall due within a year, and the gap between them is working capital.
What the statement records
A balance sheet lists what a company owns, what it owes, and the difference between them, as at one date. Assets equal liabilities plus equity by construction: every asset was funded either by borrowing or by owners, so the two sides describe the same money twice.
That identity is why balancing proves nothing about the business. A company in serious difficulty files a balance sheet that balances exactly as neatly as a healthy one.
The example below is a simplified statement. Total assets of $1,000m are funded by $600m of liabilities and $400m of equity, and the split between current and non-current is where most of the useful reading happens.
| Line | Amount | What it holds |
|---|---|---|
| Current assets | 300 | Cash, receivables, inventory: expected to convert within a year |
| Non-current assets | 700 | Property, equipment, goodwill, long-term investments |
| Total assets | 1,000 | |
| Current liabilities | 200 | Payables, short-term borrowing, the next year of debt |
| Non-current liabilities | 400 | Long-term debt, lease obligations, deferred tax |
| Total liabilities | 600 | |
| Equity | 400 | Assets less liabilities, by definition |
Current and non-current
The split is by timing rather than by importance: current means expected to be settled or converted within twelve months. It is the division that tells you whether a company can meet what falls due soon.
Working capital is current assets less current liabilities, so the company above has $100m. The current ratio expresses the same thing as a multiple, $300m against $200m being 1.5x, and the screener carries it as Current ratio.
Neither figure has a universal target. Retailers and supermarkets frequently run below 1.0 because customers pay immediately while suppliers are paid later, which is a business model rather than a warning. A manufacturer with the same ratio has a genuine problem, because its cash is tied up in inventory that has not been sold.
What equity does and does not mean
Equity is a residual: assets minus liabilities, calculated rather than measured. It records what owners contributed and what the company retained, at the values the accounts carry, and it is not an estimate of what the business is worth.
Most of the reason is that spending on research, brands, software and training is expensed as it occurs rather than recorded as an asset, so the things that make a modern company valuable are largely missing from the left-hand side. Buybacks reduce equity directly, and enough of them turn it negative at companies that are profitable and healthy.
Goodwill runs the other way. A company that buys another records the premium it paid as an asset, so growth by acquisition inflates the balance sheet in a way that building the same capability internally does not.
What sits outside it
A balance sheet is a single date, so it can be arranged. Debt repaid the week before a year end and drawn again afterwards shows a lower figure than the company carried for most of the year, and the practice is common enough to have a name in banking regulation.
Lease obligations now appear on the statement under current accounting standards, having previously sat in the notes, which materially changed the reported debt of retailers and airlines. The screener carries them separately as Lease obligations.
Contingent liabilities, litigation and guarantees are described in the notes rather than carried as a number, and pension obligations depend on assumptions set out there. The notes are where a balance sheet is actually read.
Reading it against the other statements
The balance sheet describes a position, the income statement a period, and the cash flow statement how the cash moved between them. Each answers a question the others cannot.
The most informative reading is the change between two balance sheets. Inventory and receivables rising faster than revenue means growth is consuming cash, which shows up in the cash flow statement as a working capital outflow. Debt rising while cash is flat says where the funding came from.
Company pages show ten years of each, so the comparison is a matter of reading across rather than calculating.
Common mistakes
Reading equity as company value. It is an accounting residual at historical cost.
Comparing current ratios across industries, where the working capital cycle differs by design.
Ignoring goodwill, which can be a large share of assets at an acquisitive company and is written down when an acquisition disappoints.
Taking one date as representative, particularly around a year end.
Using gross debt without subtracting cash, or the reverse, without saying which is being used.
