The Psychology of Odd-Even Pricing and Consumer Perception

Table of content


    Odd-even pricing provides businesses with a pricing strategy that uses consumer behavior and how consumers react psychologically to pricing number patterns. This pricing strategy allows retailers to price their products ending in odd or even numbers and impact consumer psychology. The last digits of a price can influence consumer perceptions as much as the initial digits.

    Odd-even pricing has historical roots in retail, initially emerging as a tactic to prevent theft by ensuring that cashiers couldn’t pocket money without opening the register. However, research revealed that odd and even prices also affected consumers’ unconscious perception of product value. Therefore, this tactic to prevent theft became a powerful tool for businesses to optimize pricing decisions.

    This article examines the dynamics of even-odd pricing and how it influences consumer behavior. It also investigates the methods in which merchants utilize this pricing tactic efficiently to influence customers’ price perception and impact buying decisions.

    Evolution of Odd-even Pricing

    The concept of odd-even pricing emerged organically in the late 1800s and grew in popularity in the 1920s. Its roots lie in practical considerations, and here’s how it all began:

    Preventing Theft:

    • Initially, odd-even pricing served as a way to prevent theft by store employees.
    • When products were priced at whole numbers (e.g., $5 or $20), customers often paid the exact amount and didn’t require change.
    • This situation allowed cashiers to potentially pocket the entire sum without opening the cash register.
    • Introducing prices like $19.99 forced cashiers to give change and accurately record transactions.

    Research and Perception:

    Over time, businesses and economists examined customers’ buying habits and behaviors:

    • They discovered that odd and even prices had different effects on unconscious perceptions of product value.
    • The human brain processes numbers from left to right, emphasizing the first digit in a price.
    • For example, when shoppers see $24.99, the “24” acts as an anchor even if they know that $29.99 equals $30, their subconscious registers the item as less expensive than seeing $30.00.
    • The odd-number cent value (“.99”) allows vendors to reduce the price while maintaining profitability.
    • Similarly, $299 appears significantly cheaper than $300, even though the difference is just $1.

    Psychology of Odd-Even Pricing

    Odd-even pricing is a strategic pricing technique where product prices are deliberately set with specific numeric values ending either in odd or even numbers. This approach capitalizes on psychological principles to influence consumer perceptions of pricing fairness, value, and affordability.

    Psychologists identify three main factors contributing to the effectiveness of odd-even pricing: the left-digit effect, the picture effect, and the perceived gain effect. 

    1. Left-Digit Effect:
    • Buyers prioritize numbers in a cost and give more weight to the left-most number.
    • Illustration: A drop from $1.93 to $1.79 ($0.14 reduction) appears more substantial than a drop from $1.89 to $1.75 ($0.14 reduction) even though it is the same price difference.

    Perception: Consumers perceive larger changes when the left-most digit changes by multiple units.

    1. Picture Effect:
    • Pricing signages can have a psychological impact on buyers.
    • Consumers connect odd prices with discounts and bargains and even prices with premium quality.
    • Illustration: $9.99 is perceived as a bargain, while $10.00 is seen as a premium price.

    Perception: Consumers interpret odd prices as lower prices and even prices signal luxury or high-end goods.

    1. Perceived Gain Effect:
    • Consumers perceive a distinction in items with odd prices and feel it is a bargain over the rounded price.
    • Illustration: A product of $2.99 is considered a better deal than a similar product priced at $3.00, despite the difference of only one cent.

    Perception: Consumers view odd prices as offering more value, influencing their purchasing decisions.

    The Influence of Price Endings on Perception 

    The way a price ends can significantly impact how consumers perceive its value. 

    • Odd prices ending in 99 cents create the impression of a bargain or discount. This pricing makes it attractive to consumers who perceive the price as lower than it actually is. 
    • Even endings, like whole numbers, portray a sense of completeness and quality, suggesting a premium product. 

    Let us look at some real examples:

    Men’s Wearhouse (Odd Pricing):

    • Men’s Wearhouse, a popular men’s brand, uses odd pricing strategies, such as pricing a suit at $199.99 instead of around $200.
    • This pricing increases the discount perception among customers even though the actual difference is just one cent as customers look at prices ending in 9 as more affordable.

    Brooks Brothers (Even Pricing):

    • Brooks Brothers, a high-end fashion brand, takes a different approach. They often use even prices for their premium products.
    • Even prices convey a sense of elegance and quality. A suit of $500 feels more premium than the same suit at $499.99.

    Dollar Stores

    • Dollar stores, by their name itself, promote the idea of affordable pricing. 
    • When these stores price products at 99 cents, consumers are even more attracted as the price perception is that it is less than a dollar.

    Importance in Pricing Decisions

    Odd-even pricing is a visible cue that impacts how consumers interpret the value of products:

    • By strategically utilizing odd or even price endings, businesses can create perceptions of discounts, savings, or premium quality. 
    • The psychological effect of odd-even pricing influences consumer behavior and ultimately drives sales.

    Building Trust and Credibility 

    Odd-even pricing plays an important role in building trust and credibility with consumers:

    • Prices ending in odd numbers can be perceived as more transparent and honest, as they appear to be set with precision. 
    • Even prices may signal quality and reliability, appealing to consumers looking for premium products and willing to pay a higher price for perceived value.

    Businesses can tailor pricing and affect consumer perception of their product as a mass product or premium product

    Leveraging Consumer Psychology 

    Businesses understanding of consumer psychology is the key to implementing an effective odd-even pricing strategy:

    • By tapping into consumers’ cognitive biases and emotional responses to pricing cues, businesses can tailor their pricing strategies to elicit specific reactions and behaviors.
    • For example, highlighting odd prices in marketing materials or emphasizing savings can trigger consumers’ desire for a good deal and drive purchase intent. 
    • Similarly, framing even prices as indicative of quality or luxury can appeal to consumers seeking premium products and willing to pay a higher price for perceived value.

    Common Challenges

    Any cost strategy can pose consumer weariness in the long term if it is overused or used excessively. In today’s information-rich environment, consumers are progressively discovering cost strategies and may view odd-even pricing as manipulative or deceptive. To conquer skepticism, businesses must practice being clear and truthful with cost practices. Clearly convey the reasoning behind cost decisions and highlight the value proposal of products to establish trust with consumers.

    Tips for Implementing Odd-Even Pricing:

    • Use even prices regularly: Price most products with even values, reserving odd pricing for discounts and promotions.
    • Create memorable prices: Consider unique numbers (not just 9s and 5s) to stand out.
    • Understand your product’s value: Research thoroughly before assigning a price.
    • Monitor Consumer Response: Continuously analyze consumer behavior and feedback to fine-tune pricing strategies and adapt to changing market dynamics effectively.
    • Promotions: Businesses can integrate odd-even pricing with promotions such as limited-time discounts or special promotions with odd-even price endings to create a sense of urgency and excitement among consumers.
