Overview

Income refers to money or economic value received by a person, household, or business over a period of time. For individuals it commonly includes earned compensation such as wages and salaries as well as unearned receipts like interest, dividends, and rental payments. For businesses it denotes money generated by operations, often described with terms such as revenue, profit, or earnings depending on context. See a basic definition at income.

Key measures and terms

Common terms help distinguish different concepts of income:

  • Gross income — total receipts before deductions. For a worker this includes wages and pre-tax benefits; for a firm it is often sales or revenue.
  • Net income — the amount remaining after expenses, taxes, and deductions; businesses often call this "net profit" or "net earnings".
  • Taxable income — the portion of income subject to tax after allowable adjustments and exemptions.
  • Disposable income — money left after taxes to spend or save.

Types of income

Income can be grouped by source:

  • Earned income: wages, salary or wages, bonuses and self-employment receipts.
  • Investment income: interest, dividends, capital gains.
  • Passive income: rental income, royalties, some business income where the recipient is not active.
  • Transfer income: government benefits, pensions, and other non-exchange payments.

Business usage and international differences

In corporate accounting the word "income" can refer to different lines on financial statements. In the United States "income" commonly denotes the bottom-line profit after expenses (net income). In some other countries and contexts people use separate words such as "profit" or "earnings" to avoid confusion with revenue (total sales). For clarity, accountants and analysts specify whether they mean gross profit, operating income or net income; see further reading on profit or earnings.

History, measurement and importance

The concept of income has long been central to economics and public policy because it underpins taxation, social programs and measures of living standards. Economists distinguish between current income and wealth (stock versus flow), and national statisticians aggregate incomes to compile indicators such as national income and personal income. Accurate measurement affects fiscal policy, inequality analysis and eligibility for benefits.

Practical uses and notable distinctions

Individuals use income figures for budgeting, loan qualification and tax planning. Policymakers use income statistics to target social assistance and to design progressive or flat taxes. Important distinctions to remember: income is a flow, not a stock (wealth); gross versus net matters for spending power; and taxable income may differ from economic income because of deductions and legal rules.

Examples

  • A salaried worker’s gross income equals wages plus employer-provided benefits before payroll taxes.
  • An investor’s income might be dominated by dividends and capital gains rather than wages.
  • A company reports revenue, then deducts costs to show operating income and finally net income after taxes.
