Income statement (Profit & Loss Statement)

Also known asProfit and loss statementP&LStatement of operations

Definition

An income statement, also called a profit and loss (P&L) statement, summarizes revenues, costs, and expenses over a defined period to show net profit or loss. Where a balance sheet is a snapshot at a point in time, the income statement tells you whether the entity made money during a quarter or year.

Key takeaways

  • The income statement shows performance over a period (a month, quarter, or year).
  • Top line = revenue. Bottom line = net income.
  • Subtotals — gross profit, operating income, EBITDA — each isolate a different layer of profitability.
  • P&Ls only become useful when categorized consistently and reconciled to source data.

How Olomon thinks about this

Olomon connects the household and the businesses or entities a household owns, so cash flow at the entity level rolls into the household-level picture without spreadsheet gymnastics. That makes operating decisions — distributions, reinvestment, owner draws — traceable from balance sheet to P&L.

In-depth definition

For business owners, the income statement is the single most important operating document. For households, a personal cash-flow statement plays the same role. Either way, the value lies in consistency: the same accounts, the same categorization, every period — so trends and anomalies actually mean something.

Frequently asked questions

  • Revenue is the top of the P&L — total sales before any costs. Income (specifically net income) is what's left after subtracting all expenses, interest, and taxes.
