Profit and LossÂ formula is used in mathematics to determine the price of a commodity in the market and understand how profitable a business is. Every product has a cost price and selling price. Based on the values of these prices, we can calculate the profit gained or the loss incurred for a particular product. The important terms covered here areÂ cost price, fixed, variable and semivariable cost, selling price, marked price, list price, margin, etc. Also, we will learn the profit and loss percentage formula here.
For example, for a shopkeeper, if the value of selling price is more than the cost price of a commodity, then it is a profit and if the cost price is more than the selling price, it becomes a loss. Here, in this article, we will discuss profit as well as loss concepts along with tricks to solve problems based on it.

Profit and Loss Basic Concepts
Let us learn profit and loss concepts in maths. It is well explained in terms of cost price and selling price.
Profit(P)
The amount gained by selling a product with more than its cost price.
Loss(L)
The amount the seller incurs after selling the product less than its cost price, is mentioned as a loss.
Cost Price (CP)
The amount paid for a product or commodity to purchase it is called a cost price. Also, denoted as CP. This cost price is further classified into two different categories:
 Fixed Cost: The fixed cost is constant, it doesnâ€™t vary under any circumstances
 Variable Cost: It could vary depending as per the number of units
Selling Price (SP)
The amount for which the product is sold is called Selling Price. It is usually denoted as SP. Also, sometimes called a sale price.
Marked Price Formula (MP)
This is basically labelled by shopkeepers to offer a discount to the customers in such a way that,

Profit and Loss Formulas
Now let us find profit formula and loss formula.
 The profit or gain is equal to the selling price minus cost price.
 Loss is equal to cost price minus selling price.
Profit or Gain = Selling price – Cost Price
Loss = Cost Price – Selling Price 
The formula for the profit and loss percentage is:
Profit percentage = (Profit /Cost Price) x 100
Loss percentage = (Loss / Cost price) x 100

Profit and Loss Examples
 If a shopkeeper brings a cloth for Rs.100 and sells it for Rs.120, then he has made a profit of Rs.20/.
 If a salesperson has bought a textile material for Rs.300 and he has to sell it for Rs.250/, then he has gone through a loss of Rs.50/.
 Suppose, Ram brings a football for Rs. 500/ and he sells it to his friend for Rs. 600/, then Ram has made a profit of Rs.100 with the gain percentage of 20%.
These are some common examples of the profit and loss concept in real life, which we observe regularly.
Profit and Loss Tricks
You have learned until now how to calculate profit as well as loss and also the percentage of them. Now let us learn some tricks or formulas to solve maths problems based on gain and loss, starting from the general formulas.
 Profit, P = SP – CP; SP>CP
 Loss, L = CP – SP; CP>SP
 P% = (P/CP) x 100
 L% = (L/CP) x 100
 SP = {(100 + P%)/100} x CP
 SP = {(100 – L%)/100} x CP
 CP = {100/(100 + P%)} x SP
 CP = {100/(100 – L%)} x SP
 Discount = MP – SP
 SP = MP Discount
 For false weight, profit percentage will be P% = (True weight – false weight/ false weight) x 100.
 When there are two successful profits say m% and n%, then the net percentage profit equals to (m+n+mn)/100
 When the profit is m% and loss is n%, then the net % profit or loss will be: (mnmn)/100
 If a product is sold at m% profit and then again sold at n% profit then the actual cost price of the product will be: CP = [100 x 100 x P/(100+m)(100+n)]. In case of loss, CP = [100 x 100 x P/(100m)(100n)]
 If P% and L% are equal then, P = L and %loss = P^{2}/100
Let us explain the abovegiven formulas with examples.
Solved Problems
Q. 1: Suppose a shopkeeper has bought 1 kg of apples for 100 rs. And sold it for Rs. 120 per kg. How much is the profit gained by him?
Solution:
Cost Price for apples is 100 rs.
Selling Price for apples is 120 rs.
Then profit gained by shopkeeper is ; P = SP – CP
P = 120 – 100 = Rs. 20/
Q.2: For the above example calculate the percentage of the profit gained by the shopkeeper.
Solution:
We know, Profit percentage = (Profit /Cost Price) x 100
Therefore, Profit percentage = (20/100) x 100 = 20%.
Q.3: A man buys a fan for Rs. 1000 and sells it at a loss of 15%. What is the selling price of the fan?
Solution: Cost Price of the fan is Rs.1000
Loss percentage is 15%
As we know, Loss percentage = (Loss/Cost Price) x 100
15 = (Loss/1000) x 100
Therefore, Loss = 150 rs.
As we know,
Loss = Cost Price – Selling Price
So, Selling Price = Cost Price – Loss
= 1000 – 150
Selling Price = R.850/
Q.4: If a pen cost Rs.50 after 10% discount, then what is the actual price or marked price of the pen?
Solution: MP x (100 – 10) /100 = 50
MP x (90/100) = 50
MP = (50 x 100)/90
MP = Rs. 55.55/
Points to remember:
 Forprofit, the selling price should be more than the cost price
 For loss, cost price should be more than the selling price.
 The percentage value for profit and loss is calculated in terms of cost price.
