# What Is Price Elasticity & How to Calculate | Elasticity price of demand formula

Understanding elasticity price of demand formula is crucial for businesses aiming to set optimal prices for their products or services. It provides insights into how changes in price affect consumer demand and, consequently, revenue. In this article, we’ll delve into what price elasticity of demand is, why it matters, and how to calculate it using a simple formula.

**What is Price Elasticity of Demand?**

Price elasticity of demand (PED) measures the responsiveness of quantity demanded to changes in price. In simpler terms, it indicates how much the quantity demanded of a product or service changes when its price changes.

- If PED > 1: Demand is elastic. This means that a small change in price leads to a proportionately larger change in quantity demanded.
- If PED = 1: Demand is unit elastic. Price and quantity demanded change in the same proportion.
- If PED < 1: Demand is inelastic. Quantity demanded changes proportionately less than the change in price.

Understanding whether demand is elastic, inelastic, or unit elastic is vital for businesses to make informed pricing decisions and maximize revenue.

**Why Price Elasticity Matters**

Price elasticity provides valuable insights for businesses in several ways:

**Optimal Pricing**: Knowing the price elasticity of demand helps businesses set prices that maximize revenue. For elastic goods, lowering prices can lead to increased revenue due to higher demand. Conversely, for inelastic goods, raising prices may result in higher revenue as quantity demanded doesn’t decrease significantly.**Forecasting Sales**: Understanding how changes in price impact demand helps businesses forecast sales accurately. This is particularly useful when launching new products or during promotional campaigns.**Competitive Strategy**: Price elasticity analysis can help businesses anticipate competitors’ reactions to price changes and formulate competitive pricing strategies accordingly.

**Calculating Price Elasticity of Demand**

Price elasticity of demand can be calculated using the following formula:

Where:

**Example Calculation:**

Let’s say a company increases the price of its product from $10 to $12, resulting in a decrease in quantity demanded from 1,000 units to 800 units.
