Profit and Loss Statement (P&L)

What is a Profit and Loss Statement?

A profit and loss statement, or P&L, is another name for an income statement. It summarizes recognized revenue, direct costs, operating expenses, and other applicable gains, losses, interest, and taxes over a defined period. The resulting net income or net loss follows the accounting basis and classification policies used.

Under accrual accounting, revenue and expenses can be recognized before or after the related cash moves. Cash-basis reporting follows receipts and payments more closely, but the basis still needs to be stated before periods or businesses are compared.

Common subtotals include gross profit, operating profit or loss, EBITDA, pre-tax result, and net income. These measures are related but not interchangeable, and adjusted measures need a clear reconciliation.

Why does profit differ from cash flow?

Receivables, payables, deferred revenue, prepayments, inventory, depreciation, amortization, asset purchases, debt principal, new borrowing, and equity financing can create differences. A profitable period can still consume cash, and a cash increase does not automatically mean the period was profitable.

What do the major layers show?

• Gross profit

  Recognized revenue less COGS or cost of revenue under the company policy.

• Operating result

  Gross profit less operating expenses before the applicable non-operating items.

• Net income or loss

  The final period result after all recognized items included by the reporting framework.

P&L versus the statement of cash flows

The P&L explains accounting performance. The statement of cash flows explains cash movement across operating, investing, and financing activities. Read both with the accounting records, cash position, commitments, and runway rather than treating either statement as the whole picture.

Why it matters

The P&L helps a team understand revenue quality, direct-cost economics, operating-cost structure, and profitability over time. Period comparison and budget-versus-actual review can show which lines changed and where a plan or operating decision needs attention.

The statement cannot establish liquidity on its own. Leaders still need cash balances, receipt and payment timing, commitments, financing activity, and cash-flow information.

Simplified statement relationship

• The reporting period and accounting basis
• Recognized revenue and the applicable revenue policy
• Direct-cost and operating-expense classification
• Interest, tax, gains, losses, and other applicable period items

Simplified statement relationship

Recognized revenue − Direct costs = Gross profit
Gross profit − Operating expenses ± Other applicable items = Net income or net loss
