What is a “profit and loss” (P&L) statement?

A profit and loss (P&L) statement is a financial report that summarises a company’s revenues, costs and expenses over a specific period — typically a month, quarter or year — to show net profit or loss. P&L is synonymous with the income statement; the term “P&L” is more common in operating contexts, “income statement” in formal accounting and regulatory filings.

P&L structure

  1. Revenue (top line)
  2. COGS = Gross profit
  3. − Operating expenses (SG&A, R&D, D&A) = Operating profit (EBIT)
  4. ± Interest, other income/expense = Pre-tax income
  5. − Tax = Net income (bottom line)

P&L vs. management vs. statutory

  • Management P&L: detailed by product line, customer segment, channel — used for operating decisions.
  • Statutory P&L: IFRS or US GAAP compliant; used for audits, tax and regulator filings.
  • The two should reconcile but rarely match line-by-line because of grouping differences.

Founders and the P&L

  • Track P&L monthly with prior-period comparisons.
  • Variance analysis: explain every meaningful difference between actual and forecast.
  • Cohort-level P&L analysis reveals which customer segments are profitable.
  • P&L plus cash flow plus balance sheet form the integrated three-statement model investors expect.

Türk şirketlerinde P&L

Türk şirketleri için P&L raporlama TMS (Türkiye Muhasebe Standartları) uyarınca düzenlenir; kurumsal ölçek şirketler için TFRS zorunludur. P&L’in standart sunumu Tek Düzen Hesap Planı (THP) hesap kodlarına göre yapılır. Halka açık şirketlerde KAP’a sunulan P&L SPK tebliğleriyle düzenlenir; vergi açısından ayrı bir “Gelir Tablosu” Maliye Bakanlığı’na sunulur.

Do: publish monthly P&L with variance commentary; reconcile management to statutory P&L quarterly.
Don’t: manage solely to P&L — net income can be positive while cash flow is negative; both views matter.
