What is the difference between Gross profit, Operating income and Net income?

1-Gross profit = Sales or service revenues− Cost of goods sold (COGS)

2- Operating income = Gross profit− Selling, general, and administrative expenses

3-Net income = Operating income +or-Interest,+or- Gains or loss - Income tax

GROSS PROFIT = REVENUE - COST OF GOODS SOLD,

OPERATING PROFIT = GROSS PROFIT + INDIRECT INCOME - INDIRECT EXPENSES 

NET INCOME = OPERATING PROFIT + NON-OPERATING INCOMES - NON-OPERATING EXPENSES - INTERESTS - TAXES.

THIS IS A BOTTOM LINE FIGURE IN INCOME STATEMENT.

They are components of Mulitple income statement.Gross profit is caluclated by taking the difference between net sales minus direct expense (cost of sales). Operating income is calculated by taking a difference between from gross profit minus operating expenses(marketing and administrative) Net income actually calculated from Operating income minus tax expense, interest expense and exordinary loss etc. Net income is very close to Retained earning and can be used for futher investment or to pay dividend to stock holders.
