Porter's Five Forces Generator, Free and Online

A Porter's Five Forces generator lets you rate the intensity of Rivalry, New Entry, Buyer Power, Supplier Power and Substitutes, then export a radar diagram showing each force's strength. This one is fully editable in the browser, includes ready-made industry templates, and runs entirely on your device.

Understanding how competitive an industry actually is takes more than listing rivals, it means weighing five distinct sources of pressure that together determine whether an industry stays profitable or gets competed down to bare margins. This Porter's Five Forces generator online tool lets you rate each force on a five-point intensity scale, add supporting evidence points, load a starter template for a supermarket, tech, airline, pharma, streaming or EV industry, and export the result as a radar diagram PNG or clean formatted text. Pro Mode adds a live industry attractiveness meter calculated from your five ratings, a live radar preview, a print-ready view, and contextual strategy tips that respond to what you have actually entered.

2What Each Force Actually Measures

⚔️

Rivalry

🚪

New Entry

🛒

Buyer Power

🏭

Supplier Power

🔄

Substitutes

A worked Porter's Five Forces example makes the model far easier to apply than the definitions alone. In the airline industry, Rivalry runs very strong due to intense price competition on short-haul routes, Threat of New Entry stays weak since aircraft procurement and airport slots require enormous capital, Buyer Power is strong because price comparison sites made fare shopping effortless, Supplier Power is strong thanks to the Boeing and Airbus duopoly, and Threat of Substitutes sits moderate since high-speed rail competes on some short European routes but has no real equivalent for long-haul travel. Notice that two of the forces, Buyer Power and Supplier Power, look outward at the parties an industry transacts with, while Rivalry, New Entry and Substitutes describe the competitive structure of the industry itself.

3Where the Five Forces Model Actually Came From

The framework has an unusually clean origin story for a strategy model this widely used. Michael Porter, then a young associate professor at Harvard Business School, introduced it in his first Harvard Business Review article, "How Competitive Forces Shape Strategy," published in March 1979. He expanded the ideas in his 1980 book Competitive Strategy, and returned to the topic again in a 2008 Harvard Business Review piece that remains one of the most cited strategy articles ever written. Porter's core argument was that businesses fixate too narrowly on their direct competitors, when profitability actually depends on the wider structural forces acting on an entire industry.

Signal	What It Means for the Industry
All five forces strong	Structurally unattractive, profits get competed away regardless of execution
Strongest force identified	Where the industry needs the most active strategic defence
Weakest force identified	Often a structural advantage worth building strategy around
Mostly weak forces	Higher profitability potential for well-positioned firms

4Frequently Asked Questions

How do I create a Porter's Five Forces diagram online for free?

Name the industry or company you are analysing, optionally load a starter template for a supermarket, tech, airline, pharma, streaming or EV industry, then rate the intensity of each of the five forces and add supporting evidence points. Export the finished radar diagram as a PNG or copy it as formatted text. No signup is required, and everything is saved only in your browser.

What are Porter's Five Forces?

Competitive Rivalry, the Threat of New Entry, the Bargaining Power of Buyers, the Bargaining Power of Suppliers, and the Threat of Substitutes. Together these five forces determine how intense competition is in an industry and how much of the value it creates gets competed away rather than kept as profit.

Who created Porter's Five Forces, and where does the model come from?

Michael Porter, then a young associate professor at Harvard Business School, introduced the framework in his 1979 Harvard Business Review article How Competitive Forces Shape Strategy. He later expanded it in his 1980 book Competitive Strategy, and returned to it again in a 2008 Harvard Business Review piece that remains one of the most cited strategy articles ever published.

Can you give a Porter's Five Forces example for a real industry?

In the airline industry, Rivalry is typically very strong due to intense price competition on short-haul routes, Threat of New Entry is weak because aircraft procurement and airport slots require enormous capital, Buyer Power is strong since price comparison sites made fare shopping effortless, Supplier Power is strong due to the Boeing and Airbus duopoly, and Threat of Substitutes is moderate because high-speed rail competes on some short routes but has no equivalent for long-haul travel.

How do I actually use a Five Forces analysis once it is filled in?

Rate each force honestly rather than defaulting to the middle, then identify which force is strongest, since that is where competitive pressure is doing the most damage to industry profitability, and which is weakest, since that often points to a structural advantage worth building strategy around. An industry where every force is strong is structurally unattractive regardless of how well any single company executes.

Is my Five Forces analysis data private?

Yes. Everything, including Pro Mode's industry attractiveness meter, live radar preview and strategy tips, runs entirely in your browser using JavaScript. Your analysis is saved only in your browser's local storage, and is never sent to a server.
