• The capital of a business is the money it has available to pay for its day-to-day operations and to finance its future growth.

  • The four main types of capital include working capital, debt capital, equity and trading capital. Trading capital is used by brokerage companies and other financial institutions.
  • Any borrowed capital is offset by a debt obligation on the balance sheet.
  • A company’s capital structure determines what combination of these types of capital it uses to finance its business.
  • Economists look at the capital of a family, business, or the entire economy to assess how efficiently it uses its resources.
