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
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 |
