> Porter's competitive analysis is a method for assessing industry attractiveness through five forces: threat of new entrants, supplier power, buyer power, substitute products, and rivalry intensity. This article covers a step-by-step algorithm, a scoring method, a ready-to-use table template, a worked example, and a comparison with SWOT, PEST, and the BCG matrix.

Porter's competitive analysis is a way to understand why companies in one industry thrive for decades while those in another burn out within a couple of years. Instead of a vague sense that "competition here is high," you get a structured picture: Porter's Five Forces show who in your niche actually captures the profit. Below is what the Five Forces model is, what it consists of, a step-by-step algorithm, a scoring method, a ready-made table template, a worked example, and a comparison with SWOT, PEST, and the BCG matrix.

## What Porter's Five Forces model is and why you need it

Porter's Five Forces model is a method for analyzing industries and competitors that assesses market attractiveness through five sources of competitive pressure. The stronger these forces, the less pricing freedom a company has, and the lower the average margin in the niche.

Analyzing the five competitive forces answers three questions: is it worth entering the industry, where exactly is profit being lost, and what strategy should you choose to protect your position. Unlike intuitive assessment, the model forces you to look at the market systematically — not just at direct rivals, but also at suppliers, buyers, and potential substitutes.

## History of the model: Michael Porter and Harvard Business Review, 1979

The author of the concept is Michael Porter, a professor at Harvard Business School. He published the competitive forces model in a Harvard Business Review article in 1979. The idea was simple and revolutionary: industry profitability is determined not just by rivalry among players, but by the structure of the market as a whole. Porter later expanded the approach with his generic strategies and value chain concepts, but the Five Forces remains the most cited tool for strategic industry analysis.

## Porter's Five Forces: breaking down each element

### Force 1: threat of new entrants

The threat of new entrants shows how easily new players can enter the market and take away market share. The lower the barriers to entry, the higher the threat and the harder it is to hold prices.

Factors to assess:

1. Size of startup investment and access to capital.
2. Economies of scale enjoyed by existing players.
3. Brand strength and customer loyalty.
4. Access to distribution channels and suppliers.
5. Regulatory restrictions, licenses, patents.

### Force 2: bargaining power of suppliers

Supplier bargaining power is the ability of suppliers to dictate prices and terms. It's high when there are few suppliers, their product is unique, and switching to an alternative is expensive.

Factors: supplier concentration, uniqueness of the resource, cost of switching, the threat of suppliers integrating forward into your niche, and the share of costs this resource represents in your cost structure.

### Force 3: bargaining power of buyers

Buyer bargaining power is the ability of customers to push down prices and demand better terms. It rises with high demand elasticity, when there are few buyers and many offers.

Factors: buyer concentration, price sensitivity, cost of switching between suppliers, availability of market information, and how standardized the product is.

### Force 4: threat of substitute products

Substitute products are offerings from other categories that solve the same customer problem. A classic example: video calls as a substitute for a business trip. The more substitutes there are and the cheaper they are, the lower the price ceiling in the industry.

Factors: the price/quality ratio of substitutes, the cost of switching for the customer, and buyers' willingness to try new things.

### Force 5: intensity of rivalry among existing players

Rivalry intensity is the degree of competition among companies already operating in the niche. It's high when there are many players, the market isn't growing, and products are weakly differentiated — that's when price wars start.

Factors: number and size of competitors, market growth rate, product differentiation, height of exit barriers, and the share of fixed costs.

## How to conduct a Porter competitive analysis: step-by-step algorithm

1. **Define the boundaries of the industry.** Boundaries that are too broad blur your conclusions; boundaries that are too narrow hide substitutes. Fix the product, geography, and customer segment.
2. **Gather data on each of the five forces.** Public reports, competitor pricing, interviews with customers and suppliers, market statistics.
3. **Score each force on a scale of 1–5**, where 1 means the force is weak (attractive market) and 5 means it's very strong (maximum pressure).
4. **Calculate the overall score** as the average across the five forces.
5. **Draw conclusions and define a strategy** — identify where the pressure is critical and what to do about it.

### Scoring: the calculation formula

The overall score is calculated simply:

> **Total = (S1 + S2 + S3 + S4 + S5) / 5**, where each Sᵢ is the force's score from 1 to 5.

Interpretation: **1.0–2.3** — the industry is attractive, entry is viable; **2.4–3.6** — moderate pressure, clear differentiation is needed; **3.7–5.0** — a tough market, entry is justified only with a strong advantage.

## Quick analysis vs. full analysis: what's the difference

A quick Five Forces analysis takes 1–2 hours based on expert judgment and public data — you quickly assign scores to test a hypothesis. A full analysis relies on statistics, reports, interviews, and calculations of market share and demand elasticity. The first is useful at the idea stage, the second before major investment decisions.

| Criterion | Quick analysis | Full analysis |
|---|---|---|
| Time | 1–2 hours | Several days to weeks |
| Data source | Expert judgment | Statistics, interviews, reports |
| Accuracy | Hypothesis | Well-founded decision |
| When to use | Testing an idea | Investment, market entry |

## An example of a Porter's Five Forces analysis on a real case

Let's walk through Porter's model using the example of the urban "to-go" coffee shop niche.

![Overall industry score in the coffee-shop example: the higher it is, the tougher the market](./images/konkurentnyy-analiz-portera-model-5-sil-score.png)

| Force | Key factors | Score (1–5) | Action |
|---|---|---|---|
| New entrants | Low entry barriers, cheap equipment | 4 | Build a brand and loyalty program |
| Supplier power | Many coffee bean and milk suppliers | 2 | Lock in prices with contracts |
| Buyer power | High — customers easily switch to the shop next door | 5 | Unique product, coffee subscription |
| Substitute products | Home-brewed coffee, vending machines, energy drinks | 4 | Atmosphere, speed, service |
| Rivalry | Crowded market, price wars | 4 | Niching, specialty formats |

Overall score: (4 + 2 + 5 + 4 + 4) / 5 = **3.8**. This is high competitive pressure. Conclusion: entering the mass coffee-shop market head-on is risky — differentiation through product, location, and customer retention is needed.

## How to evaluate the results and choose a strategy

After calculating the scores, look not just at the average but also at the individual forces with the highest scores — that's exactly where profit is leaking out. From there, Porter's generic strategies come into play: cost leadership, differentiation, or focus on a niche. In the coffee shop example, cost leadership is almost impossible (low entry barriers and high buyer power), so differentiation and focus make more sense.

## Advantages and limitations of Porter's model

**Advantages:** a systematic view of the industry, simplicity, applicability to any market, and a solid foundation for strategy and for the "threats" section of a SWOT.

**Limitations:** the model is static and provides a "snapshot" of the market rather than its dynamics. It poorly accounts for digital platforms, network effects, the role of government, and complementary products. In fast-growing markets, conclusions become outdated within months. That's why, in 2024–2025, Porter's Five Forces are used not on their own but alongside other tools.

## Porter's model and other tools: SWOT, PEST, the BCG matrix

A common question is how SWOT and Porter's Five Forces relate to each other. In short: they answer different questions and complement each other well.

| Tool | What it analyzes | Focus | When to use |
|---|---|---|---|
| Porter's Five Forces | Structure of competition in the industry | External environment, industry | Assessing market attractiveness |
| SWOT analysis | The company and its environment | Internal + external | Final strategy |
| PEST analysis | Macro-environment (political, economic, etc.) | External trends | Long-term planning |
| BCG matrix | Product portfolio | Products and market share | Resource allocation |

A logical sequence: PEST provides the macro picture, Porter's competitive analysis provides industry structure, and their conclusions feed into a SWOT. The BCG matrix comes into play when you need to decide which products to invest in.

## A table template for a DIY analysis

Copy this structure into a table and fill it in for your own niche — it's a ready-made checklist for conducting a Porter's Five Forces analysis:

| Force | Factors (list) | Score 1–5 | Rationale | Action |
|---|---|---|---|---|
| Threat of new entrants | | | | |
| Bargaining power of suppliers | | | | |
| Bargaining power of buyers | | | | |
| Threat of substitute products | | | | |
| Intensity of rivalry | | | | |
| **Total (average)** | | | | |

Checklist before you start: (1) industry boundaries are defined; (2) facts — not guesses — have been gathered for each force; (3) scores are justified; (4) the 1–2 strongest forces are identified; (5) a strategy has been chosen to address them. If all five points are covered, the analysis can be considered complete.

The main takeaway: Porter's competitive analysis isn't a one-time exercise but a framework worth revisiting once a year and whenever the market changes significantly. Fill in the template, calculate the scores, identify the strongest force — and build your strategy around exactly that.

## FAQ

### What is Porter's Five Forces model in simple terms?

It's a way to understand who captures profit in your industry and how. The model breaks down competitive pressure into five sources: the threat of new entrants, the bargaining power of suppliers, the bargaining power of buyers, substitute products, and the intensity of rivalry among existing competitors. The stronger these forces, the lower the potential margin in the niche.

### How do you conduct a Porter's Five Forces analysis on your own?

Define the boundaries of the industry, gather data on each of the five forces, score each one on a scale of 1 to 5, calculate the average score, and draw conclusions. To move faster, use the table template from the article: one row per force, with columns for 'factors,' 'score,' and 'action.' A full cycle takes anywhere from one day to a week, depending on the depth of data.

### What's the difference between a quick analysis and a full Porter's analysis?

A quick Five Forces analysis takes 1–2 hours based on expert judgment and public data — you simply assign scores based on intuition and readily available facts. A full analysis relies on market statistics, reports, interviews with customers and suppliers, and calculations of market share and demand elasticity. The quick version suits hypothesis testing; the full version suits investment decisions.

### Is Porter's model still relevant in 2024–2025?

Yes, as a thinking framework it still works today, especially for assessing entry barriers and bargaining power. But it's criticized for being static: it doesn't account well for digital platforms, network effects, the pace of change, or the role of complements. That's why it's best used alongside PEST analysis and SWOT rather than on its own.

### How does Porter's model differ from SWOT analysis?

SWOT evaluates the company itself — its strengths, weaknesses, opportunities, and threats. Porter's model evaluates the industry as a whole and the structure of competition within it. In practice, they're often linked: the Five Forces and PEST feed into the 'opportunities' and 'threats' sections of a SWOT.

### Can Porter's model be used for a startup?

Yes, and it's one of its best applications. For a startup, it's critical to understand entry barriers, supplier power, and the availability of substitutes — these directly affect unit economics and the chances of maintaining margin. Start with a quick Five Forces analysis, and run a full one before an investment round.
