What Is Product Life Cycle? – The 4 Stages Explained

Products have similar lives to living beings. They are born someday and they come to an end someday. Product life cycle is the set of stages a product goes through during its lifetime. The journey starts from the day it is just an idea to the day it is finally removed from the market.

Usually, there are 4 different stages in the Product life cycle.


Introduction Stage

This stage is where the idea becomes an actual product for sale in the market. A product is introduced to the market during the introduction stage. There are many features of this stage of product life cycle:

  • Small Market: This stage involves business capturing the market. Every customer is the new customer. Sales are less.
  • Buzz: This stage involves creating a buzz. A buzz about the new brand is created in the market and the potential customers and competitors get to know about the product. Many companies start to promote their product even before the introduction stage but such promotions may backfire as the competitors get time to adjust accordingly.
  • High Costs: There are no economies of scale in the introductory stage as the demand is yet to be created. This high production cost combined with distribution and marketing and promotion costs are high for the start.
  • Less/No Profits: Since the demand is yet to be created, the business starts off with a loss.

Marketing Mix in the Introductory Stage


Introductory stage of the product life cycle involves establishing a brand and executing the positioning strategies. It also involves obtaining intellectual property protection like patents and trademarks.


Price mix is decided based on the product, the competition in the market, and the future revenue generation strategies.

  • Penetration pricing –  starting with a low introductory price to attract and keep the market share. Start low increase later.
  • Price skimming – keeping the price high initially if the product is unique and the company can charge a high price for it.
  • Competition Pricing – choosing the price as it is already prevalent in the market. Competition decides the price.


This depends on the size of the company. Usually, the distribution is kept selective and scattered, to learn about what market likes and what not.

Maturity Stage

Maturity stage is when sales are at their peak and grow at a slower pace. Competitors’ product becomes more similar and it becomes hard to retain the market share during the maturity stage. Hence, the company starts more aggressive practices of lowering the price, sales promotion, adding more product lines, modifying existing product lines, opening up new distribution channels and rewarding the existing channels.

  • Decrease in Price: Increased competition may force the company to decrease the price of the product.
  • Decrease in Profits: A peak is always followed by a fall. Hence, profits start to decrease eventually.
  • Marketing Strategies: Marketing focus shifts to more of sale promotion and direct selling. Businesses focus more on capturing the competitors’ market share by making customers more brand loyal. Incentives are also provided to sellers to increase the shelf space of the product.

The maturity stage can turn out to be the introductory stage for various new product lines.
