## Price Elasticity of Demand Calculator

The Price Elasticity of Demand Calculator help us to calculate the price elasticity of demand. Price elasticity of demand is a measurement that determines how demand for goods or services may change in response to a change in the prices of those goods or services.

It is necessary to follow the next steps:

• Enter the value of the current price. This value must be positive;
• Enter the value of the new price. This value must be positive;
• Enter the value of the current quantity. This value must be positive;
• Enter the value of the new quantity. This value must be positive;
• Press the ”CALCULATE” button to make the computation.

Demand elasticity can be estimated using by the following formula:
PED = Q1 − Q0 Q1 + Q0 P1 − P0 P1 + P0
P0 is the initial price of the product;
P1 is the final price of the product;
Q0 is the initial demand;
Q1 is the demand after the price change;
PED is the price elasticity of demand.

What is the Price Elasticity of Demand Calculator?

Price Elasticity of Demand Calculator is a calculator that allows everyone to determine the perfect price for their products. The price elasticity of the demand calculator allows us to decide whether we should charge more for our product and thus sell a smaller quantity or on the other hand to reduce the price but increase the demand and have a larger quantity of products sold.

The price elasticity of the demand calculator uses the mean formula for the elasticity of demand. When we calculate this value, we can directly use the optimal price calculator to determine which price is perfect for our product.

How to calculate demand elasticity?

Demand elasticity is estimated using the midpoint:
PED = Q1 − Q0 Q1 + Q0 P1 − P0 P1 + P0 ,
where P0 is the initial price of the product, P1 is the final price of the product, Q0 is the initial demand, Q1 is the demand after the price change, and PED is the price elasticity of demand.

The price elasticity of demand is mostly negative. This means that the ratio of price and demand is inversely proportional that is, it would mean that the higher the price, the lower the demand and vice versa.

Let us consider the following example.
• If a TV that costs \$ 800, so that’s its starting price;
• Then we determine the initial demand, and we said at the beginning that it is 200 pieces per month;
• Now we should change the price, which is \$ 700;
• The next thing we need to do is measure the number of TVs sold at the new price. Suppose 250 TVs were sold at a new, reduced price;
• By using the middle formula for the elasticity of demand, we have
PED = Q1 − Q0 Q1 + Q0 P1 − P0 P1 + P0 = 250 − 200 250 + 200 700 − 800 700 + 800 = − 1.67

## What would be the price elasticity of demand?

Here is an example. If we have a TV shop and we sell 200 TVs every month for \$ 800. After a while, we think about reducing the price of the TV and therefore whether we will get more customers and whether we will be able to increase our income regardless of the reduction in the price of the product. This reflection of ours represents the price elasticity of demand. It represents how customers will behave when we change the price of our product.

E.g. If the elasticity is high, when we reduce the price, there will be a proportional increase in demand, and that leads to the fact that it paid off for us to reduce the price. This usually happens with expensive products such as cars, electronics, etc.

On the other hand, if the elasticity is low, the reduction in prices will lead to a slight increase in demand. The increase in demand will not be enough for our revenues. This usually happens when it comes to medicines, car fuel, etc.

Price demand elasticity is not related to the packaging in which the product is packaged. For example, this calculator may not calculate that it is more worthwhile to sell a 0.5-liter bottle of water for \$ 0.50 or a 1.5-liter bottle of water for \$ 1.25.

### The link between revenue growth and price elasticity of demand

If we have a negative increase in income it means that our income is declining. The elasticity of demand in prices is directly related to the increase in income. There are the following rules:

• PED = 0. PED is completely inelastic. In this case, the price change does not affect demand. Such is the case with products that are necessary for people’s lives because they will continue to buy them regardless of the price. This would further mean that if the price goes down, total revenue will drop drastically;

• −1 < PED < 0. PED is inelastic. In this case, a decrease in prices leads to an increase in demand, but we have a decrease in total revenue (because the increase in revenue is negative);

• PED = −1. PED is a unique elasticity. In this case, the decrease in prices is directly proportional to the increase in demand, whereby total revenue does not change;

• −∞ < PED < −1. PED is elastic. In this case, the reduction in prices leads to a significant increase in demand and an increase in total revenue;

• PED = −∞. PED is completely elastic. In this case, any price increase leads to a drop in demand. These are, for example, products that have a fixed value whose price is provided by law.

Why is the price elasticity of demand important to us and what does it measure?

Price demand elasticity measures how the demand for a product changes with its price. If we have that demand depends on the price, i.e. that it changes with the price, then we say that the demand is elastic. In contrast, if demand does not change with price then demand is inelastic. The best example of this is the products that people buy every day, as well as luxury and expensive products.

The main determinants of price elasticity are:
• What is the number of substitutes for a certain product on the market;
• What is the period under consideration and how it affects demand;
• What is the price of the product concerning people’s income;
• It doesn’t matter if the product is a luxury or a necessity;
• How large is the market under consideration and for which the elasticity of demand is determined.

### How can resilience affect a company’s pricing policy?

The main rule is that the company will charge for as many products as possible without affecting demand. In case the costs of product production increase, the company’s profit will fall. To compensate, the business will raise the price of the inelastic good, because its demand is less sensitive to the price of the elastic, and therefore it will not fall so much.

What is the term cross-price elasticity?
Cross-price elasticity is a measure of how the demand for one good changes after the price of another related product changes. Products that are competitors in demand will see that the demand for one product increases if the price of a competitor increases, while products for aggregate demand will look for one increase if the price of another decreases. There is a term that cross-price elasticity is positive or negative.

How is total revenue related to price elasticity of demand?
For two products that cost the same in the beginning, the total income from the inelastic product will be higher if the prices increase. The reason for this is that the demand for elasticity products is more influenced by their price, people will then stop buying them if they increase, and thus reduce the total income. As for inelastic products, they are not affected by their price, so their total income will increase.

How can we measure the price elasticity of demand?
To measure the price elasticity of demand, we need to record the price at which we sold the product and how much of the product we sold at once, and then when we change the price and measure how many products were resold, for the same period. We can then use the midpoint formula to calculate the price elasticity of demand.
