Price Digits

Align Product Type With Digit Type

Adjectives that describe your product should also describe your price.

A pair of socks for $7.88 because the 88 is a pair

Think of your product.

Perhaps it could be described as:

  • Sharp
  • Unique
  • Precise

Well, those descriptions can also apply to digits. Strive for congruence when possible: Adjectives that describe your product should also describe your price.

Why It Works

  • Congruence. Buying tickets to a concert? Since you want an emotional experience, you prefer discounts that are emotional (e.g., chance to win free tickets) because of this congruence (Chandon et al., 2000). Digits are merely a different medium to reach this alignment.
  • Scaffolding of the Mind. All abstract ideas are built from primitive ideas that we learned early in life — e.g., spatial distance helped us learn numerical distance. These primitive ideas can add neural connections between two seemingly different domains (e.g., products and digits).

How to Apply

  • Charge Round Prices For Round Products. In a pilot study, I alternated $9.37 and $10 for a knife and hammer. Participants significantly preferred $10 for hammer even though $9.37 was cheaper.
  • Charge Round Prices for Networking Events. Customers who want social connectivity will prefer numerical connectivity (e.g., $50 is connected to many numbers). For example, participants were asked to rate the loneliness of each number from 1 to 100, and they attributed more loneliness to prime numbers that couldn't be divided. Same with prices: While comparing $19 and $21, lonely participants were less deterred by $21 because of its connections to 3 and 7 (Yan & Sengupta, 2021).
$60 divided into two $30s, and these numerical connections look similar to social connections
  • Vary Your Digits to Convey Variety. Product variety seems higher when customers are exposed to more visual diversity (e.g., random shapes, types of people in ads; Khan et al., 2024). And I confirmed this effect in a pilot study: Repeating digits in a price reduced the perceived variety in a box of chocolates because people expected more repetition in the box.
  • Charge Precise Prices For Analytical Tools. Customers preferred a calculator with a precise price of $39.72 or $40.29 (vs. $40; Wadhwa & Zhang, 2015). Though one study failed to replicate this effect (Harms et al., 2018). And I couldn't replicate a similar approach. I asked respondents to rate the accuracy of a kitchen scale, and I altered the precision of the price ($18, $19.73, $20, $21.73). But these varying levels of precision didn't influence the perceived accuracy of the scale.
  • Charge Paired Digits For Paired Products. Would $7.88 convert better for a pair of socks? Similar effects happen with colors: Lonely customers prefer two colors that look similar because this visual companionship feels like social companionship (Kwon et al., 2024). Or maybe 88 can "feel right" for socks because the visual roundness resembles the shape of a sock. Perhaps 7 or 9 could deter customers because each digit has a visually sharp endpoint at the bottom.
  • Charge Lucky Digits For Lucky Products. Prices in Singapore convert better with 8 because it's a lucky number (Westjohn et al., 2017). Perhaps this idea can explain why Western marketers love 7-ending prices. Or perhaps 7-ending prices convert better for products that require luck (e.g., lottery tickets, mystery boxes, trading cards).

Caveats

  • More Research is Needed. This fundamental idea is widely supported, but the individual pricing applications need more empirical validation. I've been conducting a few pilot studies to test some of these effects, and I'll update this tactic with any successes or failures.
  • Semantics vs. Visuals. Respondents preferred $10 for a hammer, but I'm not sure if this preference was due to shared roundness in the semantic idea or visual roundness of 0.

Price Digits

Charge High Prices With 95-Endings

$49.99 feels better if this price is low, but $49.95 feels better if it's considered high.

99 being used for low prices, and 95 being used for high prices

Should prices end with 99 or 95?

It depends on the base price. Customers preferred:

  • $3.99 and $6.99 for cheap items (e.g., cheese, bug spray)
  • $49.95 for expensive items (e.g., kettle)

(Gendall, 1998; Schindler, 2006).

Researchers are unsure why this happens, but I have a hunch. The size of the price doesn't matter. What matters is the expected price.

I confirmed this effect in a pilot study.

I asked people to imagine buying flip flops, and I adjusted the expected and final price. The interaction was significant:

  • $18.99 was preferred when expecting $25
  • $18.95 was preferred when expecting $12

Why It Works

Suppose that you expect to pay $12 for flip flops.

Then you see $18.95. How does it feel?

Well, you evaluate this price by starting at $12, then traveling upward. Even though $18.95 is higher than you expected, it stopped early. It could be higher.

But $18.99 is pushed to the highest threshold in this bracket. So it feels more painful.

Conversely, an expected price of $25 will result in downward motion. Now $18.99 feels good because it pushed through a numerical boundary, while $18.95 feels like it has wiggle room to move even lower.

For simplicity:

  • End in 99 for low prices
  • End in 95 for high prices

But ultimately, the choice between 99 vs. 95 depends on the expected price and whether customers are traveling upward or downward to reach your actual price.

Framing

Describe Your Product With Directional Consistency

Products convert better when their explanation matches the directionality of their benefit.

Boost energy by increasing a hormone is better than decreasing a hormone

What is your product benefit?

Some products create an increase or decrease:

  • Skin creams reduce wrinkles
  • Shampoos increase silkiness
  • Air fresheners remove odors

And you might depict a separate change:

  • Increase in skin cells
  • Increase in blood flow
  • Reduction of hormones

Both directions should be consistent even if they're unrelated (Bharti & Sussman, 2024).

Customers preferred:

  • An energy supplement that increased a hormone
  • A sleep supplement that decreased a hormone

Why It Works

  • Processing Fluency. Something feels right, and we blame the product.

How to Apply

  • Tweak Your Explanation. Does your cream reduce wrinkles? Describe the reduction of collagen, rather than the increasing turnover of skin cells (Bharti & Sussman, 2024).
  • Tweak Your Branding. Does your supplement reduce anxiety by increasing chemicals? Swap your positioning so that it increases calmness.
  • Describe an Increase When Possible. Explanations with an increase often converted better. Similar effects occur with size: Bigger seems better, even if size is irrelevant to actual benefits (Silvera et al., 2002).

Related Applications

  • Align Directionality of Discounts. Which is better: save 30% or get 30% off? It depends on the directionality of the purchase: Discounts should reduce losses for prevention needs (e.g., save 30% on a first aid kit), but increase gains for acquisition needs (e.g., extra 30% off for bulk purchases; Ramanathan & Dhar, 2010).

Price Psychology

Add an Expensive Product to Catalogs

Raise the highest pice in your range so that existing prices seem cheaper.

Adding a $600 camera to a catalog with a $50 and $75 camera

Every price is relative.

Customers evaluate the size of prices by comparing them to a visible range (Janiszewski & Lichtenstein, 1999).

For example, a $10 gadget can be viewed differently:

  • Cheap in a range from $8 to $15
  • Meh in a range from $5 to $15
  • Expensive in a range from $5 to $12

Same price. Different perceptions.

Can't lower your price? Try raising the highest pice in your range.

Customers prefer:

  • A $50 ribeye near a $200 wine
  • A $200 projector near a $5,000 projector
  • A $5,000 proposal near a $25,000 proposal

In a catalog of 8 cameras from $50—$75, customers were willing to spend more when they saw a $600 camera (Krishna et al., 2006).

Requirement: Multiple Products

Be careful if you sell variations of a single product (e.g., SaaS plans).

Customers engage in two types of processing:

  • Discrimination - Evaluating the differences among objects
  • Generalization - Evaluating a summarized view of objects

Oftentimes, a single product triggers generalization.

Why does that matter? Because it reverses the recommendation. Raising the highest pice would backfire for customers with a summarized view because the average price would now be higher (Cunha Jr & Shulman, 2011).

Adapt your approach based on this mindset:

  • Discrimination? Raise the endpoints of your prices (e.g., raise bottom, raise top)
  • Generalization? Lower the mean of your prices (e.g., lower bottom, add cheaper items).

How to Apply

  • Delay Expensive Products for New Customers. Existing customers should prefer a $65 shirt near a $300 shirt. But new customers will be assessing your overall store image upon their first exposure. In this summary mindset, a $300 shirt would make all prices (including a $65 shirt) seem more expensive.
  • Add a Small or Free SaaS Tier. Software is usually a single platform (thus a summary mindset). Try lowering the mean of your prices by adding a cheap plan so that all plans seem cheaper.
  • Raise the Upper Limit of Price Sliders. You might provide a UI slider for customers to choose their price (e.g., donation, bonus, auction bid). With a range from $0 to $1,000, the midpoint is $500. But if you raise the upper limit to $2,000, the midpoint (and inferred social norm) is now $1,000 (Thomas & Kyung, 2019).

Related Applications

  • Expand Ranked Lists. Are you ranked #2 in your Top 5 competitors? Well, why not include 50 competitors? Or 100 competitors? You just moved from the top 40% to the top 2% without any effort (Xie et al., 2024).

Price Design

Shrink the Symbolic Size of Payments

Help customers imagine "getting more" while "paying less."

Ecommerce page that shows a product details section (what you get) is 35% of the width, whereas the payment section (what you pay) is 65% of the width, which is too wide

Space can distort meaning.

For example, a list of benefits in a pricing plan can seem smaller (and less appealing) with a lot of empty space (Kwan et al., 2017).

Benefits in a pricing plan that consume 33% of available space

But what if smallness is desired? Like pricing?

For example, you typically see two sections on a product page:

  • What you get
  • What you pay

Try shrinking the spatial width of payment sections so that customers feel like they're "getting more" while "paying less."

Like Amazon pages:

Amazon page. The left side of the page contains the product details which is 70% of the viewport. The right side contains the payment details which is 20% of the viewport

After sharing this idea in my newsletter, I noticed that Walmart changed the layout of their product pages a few months later to apply this advice:

Product page shrinking the width of the payment section and enlarging the width of the product section

Why It Works

  • Price Feels Smaller. Something about the payment feels smaller, and customers blame the price.
  • Checkout Seems Easier. Same effect with the "amount" of effort in the next step.
  • Button Feel More Clickable Toward the Right. By shrinking the size of a payment section, you can push this interaction further toward the right side of the screen so that it feels more touchable and clickable for right-handers (who comprise most of the population). In a pilot study, I confirmed that right-handers prefer buttons on the right, while left-handers prefer buttons on the left.

How to Apply

  • Categorize Layouts By Costs and Benefits. In their old page, Walmart included details about the product inside the payment section. But now there's a clearer distinction between what you get vs. what you pay.
  • Shrink at Every Gestalt Level. Payment sections should consume less space in the layout, while prices should consume less space within its section of the layout.
  • Don't Forget SaaS and Other Contexts. Perhaps you'll get more signups if your price consumes a smaller portion of height, leaving benefits to consume most of the space.
