What is Anchoring Effect?
Anchoring Effect explained clearly with real-world examples and practical significance for marketers.
Anchoring Effect is a cognitive bias where people rely heavily on the first piece of information they encounter (the “anchor”) when making decisions or judgments about subsequent information.
What is Anchoring Effect?
The anchoring effect occurs when an initial reference point disproportionately influences all following evaluations, even when that anchor bears little relevance to the decision at hand. Behavioral economist Daniel Kahneman first documented this phenomenon in his research on cognitive biases, showing how arbitrary numbers can skew rational judgment.
The effect operates through a mental adjustment process. When people encounter an anchor, they unconsciously use it as a starting point and make insufficient adjustments from there. This creates a “stickiness” around the initial value that persists despite additional information.
While there’s no precise formula for measuring anchoring strength, researchers typically calculate it using this adjustment metric:
Anchoring Index = (Final Estimate – Anchor Value) / (True Value – Anchor Value)
For example, if a product’s true market value is $100, an anchor price of $200 is shown, and consumers estimate $150 as fair value, the anchoring index would be: (150 – 200) / (100 – 200) = 0.5, indicating 50% anchoring effect.
The strength of anchoring varies based on several factors: the credibility of the source, the relevance of the anchor to the decision, the decision-maker’s expertise level, and the time pressure involved. High anchors typically pull estimates upward, while low anchors drag them down, regardless of their logical connection to the actual decision.
How Anchoring Effect Works in Marketing
Retail Pricing Strategy
Retailers frequently exploit anchoring through strategic pricing displays. Williams Sonoma famously introduced a $429 bread maker alongside their existing $279 model. Sales of the cheaper model increased dramatically because the expensive option made the original price appear reasonable by comparison, despite no changes to the $279 product itself.
Apple consistently uses anchoring in product launches by presenting their highest-tier models first. When introducing the iPhone 14 Pro Max at $1,099, they anchor consumers to premium pricing before revealing the standard iPhone 14 at $799. This sequence makes the base model feel like a bargain, though $799 remains a substantial purchase.
Subscription and Service Pricing
Subscription services apply anchoring through tiered pricing structures. Spotify presents their Premium plan at $9.99 monthly after showing their Family plan at $15.99. The individual plan appears cost-effective when anchored against the family option, even though users might have initially considered $9.99 expensive without that reference point.
Real estate agents use anchoring by showing overpriced homes first, then presenting reasonably priced options. A study of Portland housing sales found that initial listing prices influenced final sale prices by approximately $2,300 for every $10,000 increase in the anchor price, demonstrating measurable anchoring impact on major purchases.
Why Anchoring Effect Matters for Marketers
Understanding anchoring allows marketers to frame their offerings more persuasively by establishing favorable reference points. The initial price, feature comparison, or benefit statement that customers encounter shapes their entire evaluation process, making strategic sequencing crucial for conversion optimization.
Smart marketers can position competitors’ prices as anchors to make their own offerings appear more attractive. By highlighting premium alternatives or showing “before” scenarios, brands create contrast that favors their position without appearing manipulative or making direct comparisons.
The effect also applies to non-price anchors like performance metrics, satisfaction ratings, or usage statistics. A software company showing “save 40 hours per month” before revealing their modest $50 monthly fee uses time savings as an anchor to justify the investment. This approach works because the substantial time benefit makes the monetary cost seem proportionally small.

FAQ
How long does the anchoring effect last?
Anchoring effects can persist for extended periods, sometimes weeks or months after initial exposure. The durability depends on the anchor’s memorability, personal relevance, and whether subsequent experiences reinforce or contradict the initial reference point. Repeated exposure to different anchors can gradually shift perceptions, but the first anchor often maintains disproportionate influence.
What’s the difference between anchoring effect and price anchoring?
Anchoring effect is the broad cognitive bias affecting all types of judgments and estimates, while price anchoring specifically refers to using monetary reference points to influence purchasing decisions. Price anchoring is one application of the general anchoring principle, focusing exclusively on financial contexts rather than the wider range of situations where anchoring occurs.
Can anchoring backfire on marketers?
Yes, inappropriate anchors can damage brand perception and sales. Setting anchors too high may make products appear unaffordable or create unrealistic expectations that lead to disappointment. Anchors that seem manipulative or irrelevant can trigger consumer skepticism and reduce trust. Effective anchoring requires careful balance between influence and authenticity.
Does expertise reduce susceptibility to anchoring?
Expertise provides some protection against anchoring but doesn’t eliminate it entirely. Domain experts show reduced anchoring effects when evaluating familiar topics, but they remain susceptible in areas outside their specialty. Even professionals can be influenced by anchors when making quick decisions under time pressure or when facing unfamiliar variations within their field of expertise.
