Which brand equity formulation is most widely adopted today?

The most widely adopted brand equity formulation today is Interbrand's Brand Equity Formula. This model is particularly influential because it quantifies brand value by evaluating a brand's financial performance, role in purchase decisions, and competitive strength. Interbrand assesses brands based on three key components: the financial performance of branded products or services, the role of the brand in driving customer choice, and the brand's strength relative to its competitors.

This approach is highly valued by marketers and businesses because it provides a concrete, numerical representation of brand equity, making it easier for companies to compare their brands against competitors, identify brand strengths and weaknesses, and make data-driven decisions regarding brand strategy and investments. Interbrand's methodology is also recognized by organizations globally, thereby enhancing its credibility and adoption in the marketplace.

The other formulations, while useful in specific contexts, do not have the same level of widespread application or recognition as Interbrand's formula. SWOT analysis provides a strategic planning framework but does not specifically evaluate brand equity. Brand Z analysis focuses on consumer attitudes and perceptions but does not quantify brand value in the same comprehensive manner. Lastly, Brand Cycle Theory describes the evolution of brands over time but lacks a structured formula for measuring brand equity directly.
