In marketing, a need is a state of felt deprivation, a want is the form a need takes once culture and personality shape it, and a demand is a want backed by buying power, according to Kotler and Armstrong's Principles of Marketing. This guide adds a working category, pain, for purchases triggered by an immediate problem, and shows how each driver changes the message a brand should lead with.

What is the difference between needs, wants and demands?
Kotler and Armstrong define a need as a state of felt deprivation, a want as the form a need takes under cultural and personal influence, and a demand as a want backed by buying power. A person needs food, wants a pizza, and creates demand for that pizza when they can pay for it.
Marketers do not create needs, according to Kotler. They shape wants by offering specific products that satisfy a need.
What are the three purchase drivers: pain, need and want?
The pain, need and want framework sorts purchases by what triggers them. It is Everything-PR's working model and an extension of Kotler's terms, not a published standard.

What triggers the purchase
Example categories
What the message leads with
Pain
An immediate problem that needs relief
Roof leak, broken car, software outage, medical emergency
Pain-driven buyers want a fast answer, so the message should show how quickly the brand can fix the problem and prove it has done so before. Brand identity work matters less than response time and credentials.
Need-driven buyers recognize the problem but delay acting, so the message should explain the consequences of waiting and build trust over time. Education content, such as guides and comparisons, fits this driver.
Want-driven buyers respond to identity and desire, so the message should build an association between the brand and the buyer's self-image. The luxury fashion PR guide shows this approach in practice.
Brands lose buyers when the message mismatches the driver. Aspirational creative aimed at a need-driven category skips the education the buyer is looking for, and clinical education aimed at a want-driven category misses the desire.
Which categories fit each driver?
Most categories mix drivers, and the mix usually follows the price tier or the product line. The examples below reflect Everything-PR's editorial judgment.
Beauty is mostly want-driven, with need-driven pockets such as acne treatment and sensitive skin. The beauty brands and AI answers guide covers the category.
Healthcare is mostly need-driven, with want-driven segments such as wellness and premium concierge services.
Hospitality is want-driven at the luxury tier and need-driven at the mid-market and budget tiers. The hospitality PR pillar covers both.
Real estate blends need and want for a primary home and follows different drivers for investment property. See the real estate PR pillar.
Financial services are mostly need-driven, with want-driven demand at the private banking tier.
How do you apply the framework to your own category?
Apply the framework by classifying each product line, then checking whether its headlines match the driver. Three steps cover it.
Write one sentence for each product line that starts "A buyer usually arrives because" and finish it with the trigger.
Label the trigger as pain, need or want, and split mixed categories by tier or product.
Rewrite the five most-visited pages so each headline leads with what that driver cares about, using the table above.
What is the difference between a need and a want in marketing?
A need is a state of felt deprivation, such as hunger. A want is the specific form that need takes under cultural and personal influence, such as wanting a pizza, according to Kotler and Armstrong.
What is demand in marketing?
Demand is a want backed by buying power, according to Kotler and Armstrong. A want becomes demand when the buyer can pay for the product.
What is a pain-driven purchase?
A pain-driven purchase is triggered by an immediate problem, such as a roof leak or a software outage. Pain is Everything-PR's working term and sits alongside Kotler's needs, wants and demands.
Do marketers create needs?
Marketers do not create needs, according to Kotler. Marketers shape wants by offering specific products that satisfy existing needs.
