Understanding Porter's Five Forces with Real-World Examples

In the competitive world of business, understanding your market is essential for success. Michael E. Porter's Five Forces model is a powerful tool that helps businesses analyze the competitive dynamics of their industry. By assessing these forces, companies can make informed decisions that enhance profitability. This blog post will explore each of the five forces in detail, using real-world examples to illustrate their impact on businesses today.

What are Porter's Five Forces?

Porter's Five Forces framework consists of five key elements that influence the competitive intensity and attractiveness of a market. These forces are:

1. Threat of New Entrants

2. Bargaining Power of Suppliers

3. Bargaining Power of Buyers

4. Threat of Substitute Products or Services

5. Industry Rivalry

   
   

By analyzing these forces, businesses can identify opportunities and threats that could affect their market position.

Threat of New Entrants

The threat of new entrants refers to the potential for new competitors to enter a market. High barriers to entry can protect existing companies, while low barriers can lead to increased competition. Key factors that determine the threat:

• Initial investment cost

• Government policies

• Brand loyalty

• Economies of scale

Example: Jio Launch

The telecom industry as such has very high barriers to entry owing to its massive capital, licenses, and infrastructure and making it nearly impossible for new players to enter. For over a decade, India’s telecom market was dominated by giants like Airtel, Vodafone, and Idea. The sector was considered mature and closed. This is when Jio was launched, which caused a huge disruption in the telecom industry. Here's what Jio did exactly to capture the market:

• Jio spent over ₹1.5 lakh crore (USD 20+ billion) building its all-4G network before launch — something no competitor had done.

• Instead of upgrading old 2G/3G systems, Jio launched with pure 4G LTE, which allowed faster data and cheaper infrastructure scalability.

• Jio offered free data and calls for six months, shaking the entire market. This pricing strategy made it nearly impossible for existing players to match without losing profit.

• Jio didn’t sell just “telecom services.” It created an ecosystem — JioTV, JioCinema, JioSaavn, JioFiber, etc., locking users into its digital world.

Impact:

• Jio gained 100 million users in 170 days, one of the fastest customer acquisitions in world telecom history.

• Within two years, Vodafone and Idea merged, Aircel shut down, and Airtel lost massive revenue before adapting.

• Jio’s entry forced the entire sector to become data-driven, adopt digital payment models, and lower costs.

As mentioned earlier, the telecom industry had high entry barriers → low threat. But Jio’s deep pockets, tech innovation, and disruptive pricing redefined the barrier landscape, turning a “safe” industry into a hyper-competitive battlefield. It shows how a powerful new entrant with strategic intent can reshape an entire industry, even when barriers seem insurmountable.

Bargaining Power of Suppliers

The bargaining power of suppliers reflects their ability to influence the price and quality of goods and services. When suppliers have considerable power, they can dictate terms that affect a business's profitability. Key factors that determine the threat:

• Number of suppliers

• Uniqueness of inputs

• Switching cost

Example: Tata Motors

Tata Motors has a vast supplier base of over 1,200 tier-1 vendors (direct suppliers) and thousands of tier-2 and tier-3 suppliers. It sources components from India and globally — for passenger, commercial, and electric vehicles.

• Key suppliers include: Bosch (fuel systems, electronics), Tata Steel (body and chassis components), MRF (tires), Exide (batteries), and Delphi (engine management systems).

  
  

• Suppliers with lower bargaining power: For tires, Tata can choose between MRF, JK Tyre, Apollo, or CEAT; for batteries, Exide, Amara Raja, and Tata Green. An abundance of suppliers for tires and batteries gives Tata Motors leverage in negotiations, keeping costs under control.

  
  

• Suppliers with higher bargaining power: with EVs and connected vehicles (e.g., Tata Nexon EV, Punch EV), Tata now relies on fewer specialized suppliers for:

  • Lithium-ion batteries – LG Chem, Tata AutoComp–Gotion JV

  • EV motors and controllers – Bosch and Tata AutoComp collaborations

  • Infotainment systems and sensors – Harman, Bosch, Continental

  In this case, the supplier's bargaining power increases for specialized components because replacements are limited.

Bargaining Power of Buyers

The bargaining power of buyers refers to the influence customers have over pricing and quality. When their power is high, they can demand better prices or higher quality, directly impacting a company’s bottom line. Key factors that determine the threat:

• Buyer concentration

• Price sensitivity

• Product differentiation

Example: Amazon Shopping

The retail industry has seen a shift in the bargaining power of buyers due to the rise of e-commerce. Amazon has over 300 million active customer accounts globally. In India alone, Amazon had over 150 million monthly active users. Yet, the bargaining power of buyers has the upper hand in the purchases. Reasons:

• Customers can instantly switch to Flipkart, Meesho, Ajio, or Myntra in India, or Walmart, eBay, Target globally.

• Switching costs are near zero, since all apps are free, and product categories overlap heavily.

• Customers can compare prices in seconds using price comparison tools (Google Shopping, PriceDekho, etc.).

• Amazon’s own marketplace model displays multiple sellers for the same product — further intensifying intra-platform price competition.

• Delivery speeds vary from platform to platform for product-to-product.

Hence, these reasons keep the bargaining power of buyers very high in the online retail industry. This is true not just for Amazon or Flipkart, but for other online marketplaces such as Swiggy, Zomato, Zepto, Blinkit, BigBasket, etc.

Threat of Substitute Products or Services

The threat of substitutes refers to the likelihood that customers will turn to alternative solutions that fulfill similar needs. A high threat of substitutes can limit pricing power. Key factors that determine the threat:

• Availability of alternatives

• Switching costs

• Price-performance comparison

Example: Smartphones replacing cameras

Cameras were widely used in the 2000s, but have steeply declined in the 2020s. The reason is that smartphones for taking photos have been adopted worldwide. This is because:

• Smartphones are carried everywhere, and photos can be taken anytime.

• Cost-effective to buy 1 gadget instead of 2.

• All smartphones have various features like filters, animations, etc., which are not easily available in many cameras.

Let's look at the facts:

• In 2010, global shipments of digital cameras peaked at approximately 115 million units. By 2023, shipments had fallen drastically to around 1.7 million units, a 94% decline over 13 years. This shows consumers are moving away from standalone digital cameras in favor of alternatives.

• Smartphones now account for approximately 92.5% of all photos taken globally in 2025. The global smartphone user base is projected to reach 5.78 billion by 2025, making smartphone photography highly accessible.

• In the U.S., 81% of individuals use smartphones for photography, compared to only 55% using digital cameras.

• While professional photographers still use DSLRs or mirrorless cameras, smartphones have become the primary tool for everyday photography. The convenience, portability, and continuously improving camera technology in smartphones make traditional digital cameras largely redundant for casual users.

Intensity of Industry Rivalry

Industry rivalry is characterized by the competition among existing firms in the market. High levels of rivalry often lead to price wars and increased marketing costs. Key factors that determine the threat:

• Number of competitors

• Industry growth rate

• Product differentiation

• Exit barriers

Example: HDFC Bank vs SBI Bank

HDFC Bank competes with major private sector banks (ICICI, Axis, Kotak Mahindra, IndusInd) and public sector giants (SBI, Bank of Baroda). HDFC Bank holds around 10.8% market share in total deposits and 9.6% in advances. However, SBI remains the largest, with a 23% share in deposits. Reasons and ~20% of total advances. Let's see how HDFC competes with SBI:

• SBI has 22,400 branches with a presence in every district. Whereas HDFC only has 8,000 branches, which are concentrated in urban and semi-urban areas.

• The home loan rate of SBI is always lower than HDFC. For example, when SBI's home loan starts at 7.50%, HDFC's home loan rates start at 7.90%. This attracts more customers to SBI.

• For deposits less than 3 crore, HDFC offers a maximum of 6.60% interest rate, whereas SBI offers only 6.45% interest rate. This gives HDFC a hedge over SBI.

However, the profits of both the banks have been nearly equal, with HDFC in 61,600 crore profits in FY24 and SBI with 61,100 crore profits in FY24. This shows that SBI dominates by scale and branch reach; HDFC leads in profitability and efficiency.
