What Is a Profit and Loss Statement?

A profit and loss statement summarizes revenue and expenses over a period and shows operating profit or loss.

Reviewed August 2026 · Mint Associates Ltd Co · Houston, Texas

How it works

The rule, and what it turns on.

It is a period statement, unlike a balance sheet. Review revenue, gross margin, payroll, operating expenses and unusual classifications.

Example

Revenue $800,000 less $300,000 COGS less $400,000 operating expenses produces $100,000 operating profit.

Common mistakes

What we see go wrong, and what we do instead.

  • Assuming cash equals profit.
  • Classifying loan principal as expense.

A better approach

  • Compare current period with prior periods and budget.

Authority

Where this comes from, so you can check it.

IRC §6001; Treas. Reg. §1.6001-1; IRS Publication 583; IRS Small Business Recordkeeping guidance.
