Formulas of Profit and Loss 

Cost Price (CP)

The money paid by the shopkeeper to the manufacturer or money paid by the customer to the shopkeeper is called the cost price (CP) of the goods.

Selling Price (SP)

The price at which the shopkeeper sells the goods is called the selling price (SP).

Profit or Gain

Whenever, a person sells an article at price greater than the cost price, he is said to have made a profit or gain.

Profit or Gain = SP – CP [SP>CP]

Loss 

If the selling price of an article is less than its cost price, then the shopkeeper suffers a loss.

Loss = CP – SP [CP>SP]
