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
- Revenue (top line)
- − COGS = Gross profit
- − Operating expenses (SG&A, R&D, D&A) = Operating profit (EBIT)
- ± Interest, other income/expense = Pre-tax income
- − 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.
