The balance sheet shows what a company owns, what it owes and what is left for its owners at a single moment, such as the close of business on December 31. The income statement, also called the profit and loss (P&L) statement, the statement of operations or the statement of profit and loss, shows how much revenue the company earned and what it spent to earn it over a stretch of time, such as a quarter or a fiscal year. The balance sheet answers “what is this business worth on paper right now, and how is it financed?” The P&L answers “did this business make money during the period?” Net income from the P&L flows into the equity section of the balance sheet.

Point in time vs. period of time

Timing is the core difference. A balance sheet is dated “as of” a specific day. It lists balances that exist at that moment: cash in the bank, money customers still owe, debt outstanding.

An income statement is dated “for the year ended” or “for the quarter ended” a specific day. Its figures are totals that accumulated during the period. Revenue of $2 million for a year means sales added up to $2 million between the first and last day of that year. At the start of the next period, the income statement accounts begin again from zero, while balance sheet accounts carry their balances forward.

This is why accountants sometimes call balance sheet accounts “permanent” or “real” accounts and income statement accounts “temporary” or “nominal” accounts.

What the balance sheet reports

A balance sheet has three sections. Under IFRS it is formally called the statement of financial position, though “balance sheet” remains the common name.

Assets are resources the company controls. Typical line items include:

• Cash and cash equivalents, such as Treasury bills and short-term certificates of deposit
• Marketable securities, meaning stocks and bonds that trade in a liquid market
• Accounts receivable, the money customers owe for goods or services already delivered
• Inventory, the goods held for sale
• Long-term assets such as property, equipment and intangible assets

Liabilities are obligations the company owes to others:

• Debt, including bank borrowings and the current portion of long-term debt
• Accounts payable, amounts owed to suppliers for goods and services purchased
• Taxes, both accrued (owed but not yet paid) and deferred
• Other accrued expenses and unearned revenue (cash received for work not yet performed)

Shareholders’ equity is what remains after subtracting liabilities from assets. It includes capital contributed by owners and retained earnings, the cumulative profits the company has kept rather than paid out as dividends. Equity is a book figure, not a sale price: it reflects how assets and liabilities are recorded under accounting rules, which can differ widely from what a buyer would pay for the business.

The name “balance sheet” comes from the requirement that the two sides agree. Total assets must equal total liabilities plus total equity, because under double-entry bookkeeping every transaction is recorded with equal debits and credits. The balance sheet also shows the full value of long-term debts and investments, which the P&L never does; the P&L only shows costs related to them, such as interest or depreciation, for the period.

What the income statement reports

The P&L starts with revenue, the top line, and subtracts the costs of doing business:

1. Cost of goods sold
2. Operating expenses, including overhead such as rent, salaries and utilities
3. Interest expense
4. Tax expense
5. Other expenses and income, including items labeled one-time or nonrecurring

What remains is the bottom line: net income, also called net profit or earnings. If expenses exceed revenue, the result is a net loss. Many income statements also show intermediate subtotals such as gross profit and operating income, which let readers see where margin is gained or lost.

Under accrual accounting, revenue is recorded when it is earned and expenses when they are incurred, not when cash changes hands. A sale made on credit in December counts as December revenue even if the customer pays in February. This rule is what makes the P&L a measure of performance rather than a record of cash movements.

How the two statements connect

The link runs through retained earnings:

Ending retained earnings = beginning retained earnings + net income − dividends

Every dollar of profit on the P&L increases equity on the balance sheet unless it is paid out. A loss reduces equity. Because of this link, the P&L can be read as an explanation of part of the change in equity between two balance sheet dates.

The same transaction often touches both statements at once. When a company sells goods on credit, revenue rises on the P&L and accounts receivable rises on the balance sheet. When it receives a utility bill it has not paid yet, an expense hits the P&L and accounts payable rises on the balance sheet.

Example

The following figures are hypothetical and assume accrual accounting, no inventory and no income tax.

A small service company starts the year with this balance sheet:

• Assets: cash $40,000, equipment $60,000 (total $100,000)
• Liabilities: bank loan $30,000
• Equity: owner capital $50,000, retained earnings $20,000 (total $70,000)

During the year it bills customers $120,000, of which $15,000 is still unpaid at year-end. Its expenses total $90,000: $78,000 of operating costs, $10,000 of depreciation on the equipment and $2,000 of loan interest. Of the operating costs, $6,000 is a supplier bill not yet paid. The company also repays $5,000 of loan principal and pays the owner a $10,000 dividend.

Income statement for the year:

• Revenue: $120,000
• Expenses: $90,000
• Net income: $30,000

Balance sheet at year-end:

• Cash: $40,000 + $105,000 collected − $74,000 paid for expenses − $5,000 loan repayment − $10,000 dividend = $56,000
• Accounts receivable: $15,000
• Equipment: $60,000 − $10,000 depreciation = $50,000
• Total assets: $121,000
• Bank loan: $25,000
• Accounts payable: $6,000
• Owner capital: $50,000
• Retained earnings: $20,000 + $30,000 − $10,000 = $40,000
• Total liabilities and equity: $121,000

The $30,000 profit raised retained earnings, but cash rose only $16,000. The loan repayment and the dividend reduced cash yet never appeared on the P&L. The interest did. Depreciation lowered profit without any cash leaving that year, and the unpaid supplier bill reduced profit while showing up as a liability.

Where common items belong

Many practical questions come down to whether an item is an income or expense of the period, or a resource or obligation at a date.

• Commission income. Commissions earned during the period are revenue on the P&L. Commissions earned but not yet received appear on the balance sheet as a receivable (accrued income). Commissions received in advance for work not yet done are a liability (unearned income) until earned.
• Loans. Borrowing money is not income, and repaying principal is not an expense. The loan balance sits on the balance sheet as a liability. Only the interest goes on the P&L.
• Owner or director capital. Money that owners, partners or shareholders invest goes into equity on the balance sheet, not the P&L. A loan from a director to the company is a liability. Salaries paid to directors for their work are an expense.
• Outstanding creditors. Amounts owed to suppliers appear as accounts payable. The liability itself does not reduce profit; the underlying expense does, and under accrual accounting it is recorded in the period it was incurred whether or not the bill has been paid.
• Dividends and owner withdrawals. These are distributions of profit, recorded as reductions of equity, not as expenses.
• Asset purchases. Buying equipment adds an asset to the balance sheet. Its cost reaches the P&L gradually through depreciation over its useful life.
• Losses. A net loss reduces retained earnings. If losses accumulate beyond past profits, retained earnings turn negative and are usually shown as an accumulated deficit within equity.

A credit balance in retained earnings (the accumulated P&L) shows profits kept in the business. It does not automatically equal the amount a company may legally distribute; that depends on company law in its jurisdiction and on whether the company has the cash.

Exceptions and common confusions

Cash basis accounting

The rules above assume accrual accounting, which GAAP and IFRS require. Some small businesses keep books on a cash basis, recording revenue when money arrives and expenses when they are paid. On that basis, the P&L tracks cash much more closely, receivables and payables may not appear on the balance sheet at all, and the example’s gap between profit and cash would largely disappear.

Profit is not cash flow

A business can report a profit while running short of cash, for instance when customers pay slowly or when it spends heavily on equipment. It can also generate cash without profit, by borrowing or selling assets. Neither the balance sheet nor the P&L measures cash movement directly. That is the job of the third main financial statement, the cash flow statement, which reconciles net income to the actual change in cash.

The trial balance is neither statement

A trial balance is an internal working report listing every general ledger account, balance sheet and P&L alike, with its debit or credit balance. Accountants use it to confirm that debits equal credits before preparing the statements, which aggregate accounts into a standard format under GAAP or IFRS for investors, lenders and management. Year-end adjustments, such as outstanding expenses, accrued income and closing inventory, appear in the final statements even if an unadjusted trial balance does not yet include them, so a difference between the two is not necessarily an error.

P&L review vs. balance sheet reconciliation

These are two different closing checks. A P&L review is analytical: it compares revenue and expense lines with budgets or prior periods and investigates unusual swings. A balance sheet reconciliation verifies each account balance at the closing date against independent evidence, such as a bank statement, a loan statement or a receivables subledger. Reconciliation errors often change the P&L too, because many balance sheet corrections have an income or expense side.

Which statement comes first

Public companies generally present the balance sheet before the income statement in their official reports, following reporting conventions. Private companies can usually choose the order. In preparation, the sequence runs the other way: accountants finalize the P&L first, because net income is needed to calculate ending retained earnings before the balance sheet can balance.

How investors and lenders use them together

Read alone, each statement leaves gaps. A strong P&L can hide a balance sheet carrying heavy debt; a solid balance sheet can hide a business whose profits are shrinking. Together they support ratio analysis that neither statement allows on its own. Return on equity divides P&L net income by balance sheet equity. Return on assets divides net income by total assets. Interest coverage compares operating profit with interest expense, while debt-to-equity uses balance sheet figures only.

Lenders use the pair to judge whether profits can cover interest and whether assets can cover debts. Investors track how consistently a company earns and how it finances growth, comparing the figures with other companies in the same industry.

The Bottom Line

Business owners, investors and lenders need both statements, since a strong P&L can hide heavy debt and a solid balance sheet can hide shrinking profits. Read the P&L for performance over a period and the balance sheet for resources and obligations at a date. Ratios such as return on equity and interest coverage combine the two, and the cash flow statement explains why profit and cash can differ.
