Charm Pricing Explained: Do Prices Ending in 9 or 99 Really Sell More?
Short answer
Charm pricing means ending prices in 9 or 99, such as 49 instead of 50. It often increases sales because people read prices from left to right and give most weight to the first digit, so 49 feels closer to 40 than to 50. Research supports the effect, but round prices often work better for premium products and emotional purchases.
Key takeaways
- ✓The left-digit effect makes 2.99 feel much cheaper than 3.00.
- ✓Charm pricing works best when the first digit changes, for example 199 against 200.
- ✓Round prices can feel more premium and are easier to process for emotional purchases.
- ✓Overusing charm pricing can make a brand feel discount-driven.
Why does a price ending in 9 feel cheaper?
When we see a number, we start reading before we finish processing it. Research by Manoj Thomas and Vicki Morwitz (2005) showed that people judge 2.99 as noticeably smaller than 3.00, because the leftmost digit drives the first impression. The difference of one cent feels like a difference of one whole unit.
What does the research show about sales?
In a well-known set of field experiments, Eric Anderson and Duncan Simester tested prices in mail-order catalogues. A dress priced at 39 sold more than the same dress at 34 or 44. Prices ending in 9 also seemed to signal "this is a good deal", especially for customers who did not know the usual price of the item.
When should you use round prices instead?
| Use charm pricing when... | Use round pricing when... |
|---|---|
| Customers compare prices carefully | You sell premium or luxury products |
| The first digit changes (199 vs 200) | The purchase is emotional or a gift |
| You want to signal value or a sale | You want to signal quality and confidence |
| Prices are mostly online and scanned quickly | Simplicity matters, for example in services |
Round numbers are easier for the brain to process, and that ease can feel right for emotional or luxury purchases. That is why many premium brands price at 500 rather than 499.
How do you test it?
Pick one product and test 199 against 200, or 99 against 100, on part of your traffic. Compare revenue per visitor, not only conversion rate. Our guide to testing psychological pricing walks through the method step by step.
