The basic accounting equation is:

It shows that everything a company owns is financed either by creditors or by owners.

Components

  • Assets: resources the company controls, such as cash, inventory, and equipment
  • Liabilities: obligations, such as loans or Accounts Payable
  • Equity: the residual claim after liabilities are subtracted

Rearranged form:

Why it matters

  • Every transaction affects the equation.
  • The equation is the foundation of the Balance Sheet.
  • Profit ultimately flows into equity, which connects it to the Income Statement.

Simple examples

  • Borrow cash: assets up, liabilities up
  • Buy equipment with cash: one asset up, one asset down
  • Earn revenue in cash: assets up, equity up
  • Pay a supplier: assets down, liabilities down
