Math Formulae: Profit, Loss and Discount

 Some important Profit, Loss and Discount formulae:

Terms Used: CP = Cost Price,     SP = Selling Price,     , MP = Marked Price

1. Profit = SP - CP
   
   
2. Profit % = 

   	(SP - CP)
   	CP

     × 100  = 

   	profit
   	CP

     × 100  
   
   
3. Loss = CP - SP
   
   
4. Loss % = 

   	(CP - SP)
   	CP

     × 100  = 

   	loss
   	CP

     × 100
   
   
5. SP = 

   	100 + profit %	× CP
   	100

      or,
   SP = 

   	100 - loss %	× CP
   	100

   
   
   
6. CP = 

   	100	× SP
   	100 + profit %

      or,
   CP = 

   	100	× SP
   	100 - loss %

   
   
   
7. SP = (100 + p) % of CP; where profit is p % of CP.
   
   
8. SP = (100 - x) % of CP; where loss is x % of CP.
   
   
9. When two articles are sold at same price, but one at profit of x % and other at loss of x % then there will be a loss, and
   loss % = 

   	x ²
   	100

   
   
   
10. MP = CP + Markup, i.e.
    MP = CP +(% markup on CP)
    
    
11. Discount = % discount on MP
    
    
12. SP = MP - Discount
