Price Elasticity of Demand Calculator

The price elasticity of demand calculator is a useful tool for anyone seeking to find out how much to charge for their goods. You can use this calculator to determine if you should charge more for your product (and sell fewer units) or lower the price while increasing demand. The elasticity of demand is calculated using the midway formula. After you've established its value, go straight to the optimum pricing calculator to find out what the best price is for your product.

Elasticity of Demand Formula

Given the existence of easy elasticity calculators, it is nevertheless necessary for anyone in business to grasp the formulas for manual calculations. The PED is the ratio of a percentage change in demand for a product to a percentage change in the price of that product. The formula for the elasticity of demand is:

The elasticity of demand = Percentage change in quantity demanded/Percentage change in price

Where: Percentage change in quantity demanded = New quantity demanded (∆Q)/Original quantity demanded (Q)

Percentage change in price = New price (∆P)/Original Price (P)

Hence, the formula for PED is: PED = [ (Q₁ – Q₀) / (Q₁ + Q₀) ] / [ (P₁ – P₀) / (P₁ + P₀) ]

  • Where P₀ = product’s initial price;
  • P₁ = product’s final price;
  • Q₀ = initial demand;
  • Q₁ = demand after the change in price;

How do you find out how much demand has changed?

A shift or change in the total demand of the market is referred to as a change in demand. It's depicted graphically as a quantity versus price plane. Demand fluctuates as a result of fewer or more market entrants, as well as any changes in customer preferences. Non-parallel or parallel changes are possible.

A positive change in the demand even with frequent swings of supply would suggest that there is a rise in the product’s quantity and price. Negative changes in demand suggest that both the quantity and price of the commodity will decrease.

Simply expressed, the difference between the new demand (Q1) and the original demand (Q) is the change in demand (∆Q). You can use the following formula to find it out:

∆Q = Q1 – Q

How to find the Price Elasticity of Demand?

  1. Obtain the demand function as well as the price at which you wish to determine the elasticity.
  2. Differentiate the demand function from the price function.
  3. Multiply the price by the differentiated function.
  4. To get Q, plug the price into the demand equation.
  5. Step 3's result is divided by step 4's result.
  6. The percentage price elasticity of demand at your chosen price is the result.

FAQs on Price Elasticity of Demand Calculator

1. What is the price elasticity of demand?

The price elasticity of demand measures how much a good's demand changes in response to its price. When demand varies in response to price, it is said to be elastic, and when it does not, it is said to be inelastic. Each of them is exemplified by luxury and necessary products, respectively.

2. What is cross-price elasticity?

Cross price elasticity is a measure of how demand for one good changes when the price of other related goods changes. Items in competitive demand will see an increase in demand if the price of the rival increases, but products in joint demand will see an increase in demand if the price of the other lowers. The cross-price elasticity is described as positive or negative, depending on the situation.

3. What are the main factors that influence the price elasticity of demand?

The following are the factors determinants of price elasticity:

  • The amount of product replacements available on the market.
  • The timeframe in question and how it influences demand.
  • The product's price in relation to people's income.
  • The size of the market under consideration.

4. What impact does elasticity have on a company's pricing strategy?

In general, corporations will charge as much as they can for a product without impacting demand. When the cost of creating a product rises, so do the earnings of the company. To compensate, the company will increase the price of an inelastic good, whose demand is less price sensitive than that of an elastic good and hence will not decline as much.

5. What is the method for calculating demand price elasticity?

You could note the price at which you sold a product and how much of it you sold at one time to get the price elasticity of demand, then alter the price and measure how much of the product was sold again over the same time period to determine the price elasticity of demand. The price elasticity of demand can then be calculated with the midpoint formula.
