Understanding Price Elasticity of Demand

What is the price elasticity of demand? Read on to learn more about the importance of price elasticity and how it can help you accurately price your products and services.

How you set your prices affects all aspects of your business. Your prices should always remain competitive while helping you earn a high enough revenue to make your business successful.

Your pricing affects your profit margin, with many companies implementing price increases to boost revenue as long as they don't lose sales. However, higher prices can also lead to lower sales volumes.

Learning how to price your products can help set you apart while attracting loyal customers. But how does pricing affect your business? It's all about supply and demand.

Price elasticity of demand is the customer's responsiveness to price changes. For example, if there's a price increase, you might lose customers, which can affect total revenue. However, if you decrease your prices, you might earn a few more customers.

Ultimately, how do customers react to your price changes? Are they ordering more or less? As a business owner, it's crucial to understand price elasticity so you can have a better idea of how to price your products or services.

So what is price elasticity of demand, and why is it important for your business? Continue reading to learn more about the definition of price elasticity of demand and how it can affect your business.

What is price elasticity of demand?

Price elasticity of demand is a way to measure how responsive customers are to changes in the price of a product or service.

This measurement can help you understand whether your business's pricing strategy attracts or deters customers, so you can make better decisions to increase your profits.

For example, an e-commerce company selling supplements might increase its price and see reduced demand for a certain product. While they may need to increase prices to keep up with rising costs, this can directly impact their revenue.

Price elasticity of demand is used to understand supply and demand for products when there are shifts in pricing. Your market demand curve might tell you that your products are in high demand, only for an increase in your pricing to scare all your customers away.

Formula for the elasticity of demand

Knowing how to calculate price elasticity of demand can tell you if a product or service is elastic—meaning the demand changes substantially even with the slightest price changes.

So, what is the formula for the price of elasticity demand?

To calculate price elasticity of demand, you should divide the percentage change in quantity demanded by the percentage change in price.

You can calculate the price elasticity of demand for any product. For example, let's say you're an e-commerce company that sells dog treats. You typically sell 500 units per month for $50 per unit.

If you raise your price by 10% to $55 per unit and only sell 450 units, the equation looks like this: -10%/ 10%= -1

In this case, your price increase earned your company $24,750 (450 x 55) compared to the original values, which gave you a revenue of $25,000 (500 x 50). Therefore, you've lost $250 by increasing the prices that month, so your total revenue falls due to a change in price.

Understanding the demand formula is crucial so you can make informed decisions about inventory and pricing.

Using the above example, if your customers are used to paying an average price of $50 per unit and the price suddenly increases by 10%, they may opt for a competitor instead.

This is exactly how price elasticity can affect the demand curve for a product or service. When the price of a product increases, the quantity demanded falls, and the demand curve slopes downward to the right.

Types of price elasticity of demand

There are three main types of price elasticity of demand: Unit elastic demand, inelastic demand, and elastic demand.

Unit elastic demand

Unit elastic demand occurs when the price elasticity of demand equals 1. Unitary elasticity happens when the price change equals the quantity demanded. Ultimately, the percentage of change for both is the same.

For example, if the price of coffee changes by 10%, you might see a 10% increase in demand because the price is lower.

Inelastic demand

Inelastic demand occurs when the price elasticity of demand is less than 1.

In the example above, we had an elasticity value of -1, so our products are inelastic. When something is perfectly inelastic, a small price increase or decrease will not impact the demand.

Inelastic goods are typically those people can't live without, such as fuel, groceries, toilet paper, and medication. With these products, if the prices increase substantially, people are still likely to buy them. However, if the price falls, demand may increase, potentially reducing the overall supply.

Elastic demand

Elastic demand is any elasticity value greater than 1. Elastic goods have a much more dramatic change in demand when there's a small price change.

These are typically considered non-essential goods like clothing, cars, certain appliances, entertainment, and luxury items.

Why is price elasticity important?

Price elasticity can help you compare different pricing methods to accurately price and market your products and services.

For example, based on your industry and the products you sell, you can assume they're either elastic or inelastic and create a pricing strategy that reflects your brand.

Let's say you're an e-commerce business that sells luxury nightgowns. This is an example of an elastic product—if the price rises, you'll see a decrease in the quantity demanded. Conversely, you'll get an increased quantity demanded if the price drops.

So what does this tell you? Ultimately, it can tell you whether to increase or decrease your prices to stay competitive based on the profile of your target audience.

For example, if your target audience makes $50,000 to $75,000 per year, you can assume they're more likely to purchase your products when the prices are lower. However, you must also ensure this doesn't cost your business money.

If you can increase your prices without decreasing demand, it makes sense to do it. However, if your products are inelastic and a small price change leads to a dramatic decrease in quantity demanded, you should consider how it will affect your bottom line.

However, the price elasticity of demand is rarely perfectly inelastic or perfectly elastic. It's usually estimated using data on the change in the quantity demanded and the change in price over a given period of time.

This estimated price elasticity can be used to predict how price changes will affect the quantity demanded, which can help businesses make better pricing and production decisions.

Factors that affect price elasticity of demand

Several factors can impact the price elasticity of demand to determine the responsiveness and relationship between your price and quantity demand.

Here are a few things to consider when pricing your products that may affect whether demand is price elastic or inelastic:

Availability of substitutes

Your business likely has a lot of competition, and price changes can impact whether your customers stay or go.

For example, if you sell pet products for $50 per item, your competitor might sell similar items for $45. If there are alternatives or substitutes for your customers, it's easier for them to switch to the competition if you increase your price.

However, if there aren't substitutes, the price will be less elastic. For example, everyone needs electricity. If the price goes up, it's highly unlikely customers will prefer to go without it.

Necessity of the product

There are a few things many people need, like food and shelter, along with everyday items like gas. Items more likely to be considered necessities are less elastic than things customers might deem as "wants" instead of "needs."

For example, customers want coffee in the morning, but they don't need it. Therefore, if you increase your prices, you might see a drop in demand, especially for luxury items.

Time period

To understand the impact of price elasticity of demand, you have to account for how much time you allow for a response. The longer you give customers to respond to a change in price, the more significant the response.

For example, increasing the price of bananas might not affect people for weeks because not everyone buys bananas on the same day.

Meanwhile, decreasing your prices can take time for customers to realize and respond to them.

Proportion of income spent on the product

Your customers likely have strict budgets. If they spend too much money on your product due to a price increase, they probably won’t purchase it again, especially if cheaper substitutes are available.

In addition, price changes affect how much customers can buy and spend. For example, let's say you sell t-shirts. If the price increases from $10 to $20 and consumers only have $100 to spend, they go from buying 10 to 5 t-shirts, which impacts your revenue.

How important your product is compared to other items in a household budget will ultimately determine whether it's inelastic or elastic.

Brand loyalty

While some customers choose brands simply based on pricing, others are extremely loyal to certain companies, especially if you provide them with value.

For example, loyal customers might refuse to purchase clothing from any other brand if you sell high-quality clothing. Brand loyalty is crucial and can help you keep as many customers as possible, even if you change the price.

However, there are other factors to consider, especially if you have an elastic product prone to demand shifts when pricing changes.

That said, brand loyalty can help prevent customers from seeking substitutes, which can help you increase your revenue if you decide to raise prices.

How price elasticity can affect your business

Price elasticity can tell you whether or not to increase your prices based on the products you sell and your target market. You spend a lot of time deciding how to price your products and services to help you stand out without alienating your target customers, so you want to choose carefully.

Price elasticity varies by product and industry, but knowing how to calculate the price elasticity of demand can help you determine how price changes can impact your business.
