What Is a Balance Sheet? How to Read One, Line by Line

A balance sheet is a snapshot of a company's financial position at a single date: what it owns (assets), what it owes (liabilities), and what is left over for the owners (equity). Unlike the profit and loss statement, which covers a period, the balance sheet describes one moment — usually the last day of a month, quarter or financial year.

The equation that always holds

Every balance sheet is an expression of one identity:

Assets = Equity + Liabilities

It balances by construction, not by luck. In double-entry bookkeeping every transaction posts equal debits and credits, so anything the company owns is always financed by someone — either the owners (equity) or someone else (liabilities). If a balance sheet doesn't balance, the books contain an error; the statement format cannot express one.

A worked example

A small EU services-and-goods company at 31 December, in euros:

	Amount
Non-current assets	18,000
Equipment (cost 24,000, accumulated depreciation −6,000)	18,000
Current assets	28,000
Inventory	12,500
Trade receivables	9,300
Cash and bank	6,200
Total assets	46,000
Equity	17,300
Share capital	2,500
Retained earnings (incl. current-year profit)	14,800
Non-current liabilities	12,000
Bank loan (due after more than 12 months)	12,000
Current liabilities	16,700
Trade payables	8,400
VAT payable	2,100
Payroll liabilities	2,700
Deferred income	3,500
Total equity and liabilities	46,000

Total assets equal total equity and liabilities: 46,000 = 17,300 + 12,000 + 16,700.

Line by line

Non-current assets are things the company expects to use for more than a year: machinery, vehicles, buildings, software, long-term investments. They are carried at cost minus accumulated depreciation, so this line quietly tells you two things — what the company invested, and how much of that investment accounting has already written off as used up.

Current assets are listed in order of how quickly they turn into cash:

• Inventory — goods held for sale, valued at what they cost to acquire or produce (commonly under FIFO). Inventory is only worth its balance-sheet value if it can actually be sold.
• Trade receivables — invoices issued to customers but not yet paid. A growing receivables line is revenue the company has recognized but not collected; its quality shows up in a debt-aging report, not here.
• Cash and bank — the only line that needs no interpretation.

Equity is the residual: assets minus liabilities. Share capital is what the owners formally put in; retained earnings are accumulated profits the company kept instead of distributing. Equity is not a pile of money — it is a claim on the asset side, already invested in equipment, inventory and receivables.

Non-current liabilities are debts due after more than twelve months — typically bank loans and lease obligations. The twelve-month rule is the whole distinction: the portion of a loan due within the next year belongs in current liabilities, even if the loan itself runs for a decade.

Current liabilities are obligations due within a year:

• Trade payables — supplier invoices received but not yet paid. Free short-term financing, as long as suppliers stay willing.
• Tax and payroll liabilities — VAT collected on behalf of the state, income tax withheld from salaries, social contributions. This money was never the company's; it is only passing through.
• Deferred income — cash received for goods or services not yet delivered (a contract liability under IFRS 15). It converts to revenue as the company performs, not when it is paid.

How to actually read one

The individual lines matter less than the relationships between them:

• Working capital = current assets − current liabilities. Here: 28,000 − 16,700 = 11,300. Positive means the company can cover the coming year's obligations from assets that will become cash in the same window.
• Current ratio = current assets ÷ current liabilities = 1.7. Below 1 means short-term obligations exceed short-term resources. The quick ratio drops inventory from the numerator — useful when inventory is slow to sell: (28,000 − 12,500) ÷ 16,700 ≈ 0.9.
• Leverage — compare debt to equity. Total liabilities of 28,700 against equity of 17,300 is a debt-to-equity ratio of about 1.7. Whether that is comfortable depends on how stable the cash flows are.
• Negative equity — liabilities exceeding assets — means accumulated losses have consumed the owners' investment. It is also a legal trigger in much of the EU: in Lithuania, for example, if equity falls below half of the share capital, shareholders are required to restore it or reduce the capital.
• Trends beat snapshots. Receivables growing faster than revenue, inventory growing faster than sales, or cash shrinking while profit grows are all patterns a single balance sheet cannot show but two consecutive ones will.

Balance sheet, P&L and cash flow

The three statements answer different questions about the same books. The balance sheet is a stock — position at a date. The profit and loss statement is a flow — performance over a period, and its bottom line rolls into retained earnings on the balance sheet. The cash flow statement reconciles the two by explaining what happened to actual money, which is how a profitable company on the P&L can still run out of cash on the balance sheet.

Where the numbers come from

A balance sheet is not typed in — it is derived. Every account in the general ledger carries a running balance; a trial balance lists them all, and the balance sheet maps those accounts into the statutory layout. Under the EU Accounting Directive (2013/34/EU), how much detail the layout must show depends on the company's size category: micro, small, medium or large.

In Nordlet both steps are one API call each: POST /v1/reports/trial-balance returns the account balances, and POST /v1/reports/financial-statements { fromDate, toDate, category } returns the balance sheet and profit and loss in the layout for the given size category. Because postings are balanced by the ledger itself, the statement balances by construction. For a group of companies, the consolidation guide covers combining several balance sheets into one.

FAQ

Does a balance sheet always have to balance?

Yes. Assets always equal equity plus liabilities, because double-entry bookkeeping posts equal debits and credits for every transaction. A "balance sheet that doesn't balance" is a bookkeeping error surfacing, not a property of the business.

What period does a balance sheet cover?

None — that is the point. It shows the position at a single date. Performance over a period is what the profit and loss statement shows; the two are linked because the period's profit ends up in equity as retained earnings.

What is the difference between a balance sheet and a trial balance?

A trial balance is the raw list of every ledger account with its debit or credit balance — an internal working document. The balance sheet groups and maps those balances into a statutory presentation: assets, equity and liabilities, in a layout defined by accounting law.

Can equity be negative?

Yes — when accumulated losses exceed the capital the owners put in, liabilities are larger than assets. Beyond being a solvency warning, it has legal consequences in many EU countries, from mandatory recapitalization to directors' liability, so it is a line worth watching every period, not just at year-end.

How often should a balance sheet be prepared?

Formally it is filed annually, but since it is derived from the ledger, there is no cost to producing it monthly. Companies that watch working capital monthly see cash problems quarters before they become existential.
