Break-even analysis

  • If the business sells more than the break-even level of output then it will make a profit and if it sells less, it will make a loss.
  • Businesses use this to calculate the output needed to make a profit.
  • The break-even level of output is the level of output at which the firm’s revenue is equal to the total costs.
