Elasticity of Demand: Why Price Changes Do Not Affect Every Product the Same Way

Raise the price of one product and orders fall immediately. Raise the price of another product and demand barely changes.

This difference is elasticity of demand.

For manufacturers, elasticity is not just an economics textbook idea. It affects pricing, production planning, inventory, customer negotiations, and margin decisions. If a product is highly price-sensitive, a small increase can reduce volume. If demand is inelastic, the business may have more pricing power, especially when the product is critical, customised, or difficult to replace.

AICAN Optiwise helps manufacturers connect sales, inventory, production, and reports so demand behaviour can be reviewed with actual business data.

What Is Elasticity of Demand?

Elasticity of demand measures how much demand changes when price changes.

If demand changes a lot when price changes, it is elastic.

If demand changes very little when price changes, it is inelastic.

The common formula for price elasticity of demand is:

Percentage change in quantity demanded / Percentage change in price

Example:

If price increases by 10 percent and demand falls by 20 percent, demand is elastic.

If price increases by 10 percent and demand falls by only 2 percent, demand is relatively inelastic.

Why Elasticity Matters for Manufacturers

Manufacturers often face input cost changes. Raw material prices rise. Labour costs increase. Freight changes. Energy costs move. The business must decide whether to pass cost increases to customers.

Elasticity helps answer: how will customers respond if we change price?

It also helps with:

• Pricing strategy
• Margin protection
• Product mix decisions
• Forecasting
• Inventory planning
• Customer negotiation
• Discount control
• Capacity planning

A manufacturer that understands demand response can avoid blind price changes.

Elastic Demand Example

A manufacturer sells a standard component that many competitors also supply. Customers can switch vendors easily. If price increases, buyers may move to another supplier.

This product has elastic demand.

In this case, price increases must be handled carefully. The business may need to improve service, quality, delivery reliability, or bundling before raising price.

Inelastic Demand Example

A manufacturer supplies a customised component used in a customer’s critical machine. The part has strict specifications and few alternate suppliers.

Demand may be less sensitive to price because replacement is difficult and downtime cost is high.

This product has more inelastic demand.

The manufacturer may have better pricing power, but customer trust still matters.

Factors That Affect Elasticity

Availability of substitutes.

Importance of the product to the customer.

Share of product cost in customer’s total cost.

Customer urgency.

Brand or supplier trust.

Quality differences.

Switching cost.

Contract terms.

Market competition.

Time period. Demand may be inelastic in the short term but elastic over time as customers find alternatives.

Elasticity and Inventory

Elasticity affects inventory decisions.

If a product is price-sensitive and demand is uncertain, overproducing can create excess stock.

If demand is inelastic and product is critical, stock availability can become a competitive advantage.

If raw material prices rise, a manufacturer may need to decide whether to buy ahead, adjust price, or reduce exposure.

This is why sales and inventory data should be reviewed together.

Common Mistakes

One mistake is assuming all products behave the same way.

Another mistake is changing price without tracking volume response.

Some businesses discount products that customers would have bought anyway.

Some avoid price increases even when demand is inelastic and margin is suffering.

Some do not separate customer segments. One customer group may be price-sensitive while another values delivery reliability more.

How to Use Elasticity Practically

Review sales volume before and after price changes.

Compare demand by product category and customer segment.

Track lost orders and reasons.

Look at competitor availability.

Review margins along with volume.

Use small controlled price changes where possible.

Connect pricing decisions to inventory and production planning.

Optiwise by AICAN helps manufacturers analyse demand patterns through connected sales, inventory, and reporting data.

Founder’s Note

Pricing should not be guesswork. Many manufacturers either raise prices too late or discount too easily because they do not see demand behaviour clearly.

At AICAN, we believe better data gives owners more confidence. Optiwise is built to help manufacturers connect demand, stock, and margin signals.

FAQs

What is elasticity of demand?

Elasticity of demand measures how much quantity demanded changes when price changes.

What is elastic demand?

Demand is elastic when customers strongly reduce buying after a price increase or strongly increase buying after a price decrease.

What is inelastic demand?

Demand is inelastic when price changes have limited effect on quantity demanded.

Why does elasticity matter for manufacturers?

It affects pricing, margin, production planning, inventory decisions, and customer negotiation.
