Odd-Even Pricing: Here’s The Price Ending You Should Use

Something that always puzzled me was how virtually no one uses prices ending in ,00 anymore.

E.g. $50.00, 300.00€, or £500.00.

Creators, shops, and businesses focus uniformly on prices ending in 7 (97, 497, 997) or 9 (99.99, 499.99, 999.99).

Until recently, I never really understood why basically everyone prices that way.

I also wondered if the last digits of a price tag actually make any difference.


Turns out it does.

Here’s the short answer to what price ending you should use.

Use prices that end in 99 or 49.

Not prices ending in 7 (97, 47) nor prices ending in 5 (95 or 45)


Because research shows that the price isn’t perceived as lower by customers, as opposed to when prices end with 99 or 49.

But that is the short answer.

The long answer is a bit more convoluted, and includes a few “depending on” phrases.

First of all, customer perception is built up over time as a reaction to the pricing strategies producers use.

In other words, if everyone uses ,99 pricing (or “odd pricing”), maybe you can stand out by using ,95 (or “even pricing”) price endings.

And vice versa.

Your price ending strategy needs to be adapted into the context of your niche, taking into account what your competition is doing, and how your customers are reacting.

But as a starting point, research shows that it’s better to favor .9 endings above all others. If you’re interested in hearing why this is, read on…

In today’s world filled with technological wonder, one might assume that humans are rational beings. That is a mistake.

Why do price endings matter?

The reason why you’d put even a few seconds of thought into this, is that customers or humans in general tend to ignore the rightmost digits in a price.

If I sell something at 499.99, the main focus is on the 4. If I sell something at 500,00, the main focus is on the 5.

Even if the difference between the values is only 1 single cent, psychologically the difference is perceived as far bigger.

For each situation, consumers choose an ‘‘optimal’’ decision rule by trading off the accuracy of the rule against the mental cost of using it.

Steven Shugan in “The Cost of Thinking” (1980)

Put differently, when people need to make choices, they balance the “best” decision with the cost of actually choosing it, and then do something that’s almost as good, but doesn’t take as much energy.

This is commonly known as the path of least resistance.

So in the context of price shopping, the eyes quickly scan the prices left-to-right (in Western countries) and see that something costs 49 dollars and some cents, instead of 49,99.

This is a learned trait that goes thousands of years back.

And it’s nothing that we can turn off.

It is programmed into our lizard brains – our oldest part of the brain – to spend as little energy as possible on whatever we’re doing.

Why do you think microwaves exist? Why does every single TV nowadays come with a remote? And why does everyone use Bluetooth headphones instead of old corded ones?

The answer to these questions are the same as the answer to why price endings matter.

Efficiency, simplicity, and less energy spent.

… Ok!

Now we know why price endings matter. Next we’ll take a look at which price endings to use.

Here’s why you should use prices ending in 9

The rightmost digits most often used in pricing are 0, 5, and 9.

From past studies on this topic, several advantages of using ,9 endings have been spotted:

  • A higher price point is better because customers think that higher price equals higher quality
  • Schindler’s 2006 study stated that prices ending in 9 convey that the “price hasn’t recently been increased”
  • The same study found that if the ending is 9 or 8, “it’s probably on sale”
  • Similarly, if the ending is 9 or 8, customers thought that they could probably not find a price lower than this elsewhere.

Some have even gone so far to state that ,99 are better, because the 99 looks like eyes looking at you, which makes you give more attention to them.

Humans are anything but rational. Capable of great, beautiful feats. But also of incredible silliness.

I couldn’t find any info or studies that would make this anything else but a suggestion, so take it with a grain of salt.

I did find studies that criticized price ending strategies that end prices in 9.

The general line of thought in those studies was that high-price conscious customers (aka people who are very picky about price and who are likely to shop around for the cheapest alternative) do not respond well to this strategy.

But there’s nothing suggesting that these customers would respond better to any other option. Just the mere statement that they respond worse than other customer groups to this tactic.

So in other words, it does not really matter, as whatever price you put, these customers will always be very calculative in their buying.

Could prices ending in 5 be superior?

According to research, no.

Prices ending in 5 (ie. $14,95) do not correlate between a perceived “lower price” factor. The correlation is strong for prices ending in 9, however (ie. $29,99).

There is nothing that would suggest that prices ending in 5 would be superior to prices ending in 9.

All the positive price ending effects i could find were tied to prices ending in 9. I couldn’t find any promoting 5’s.

The only time it would be viable to use endings such as these, were if all other prices were priced differently.

Then, people might focus more on that specific product as it would differ from the rest.

To conclude

The odd-even pricing debate is one I don’t follow with much interest. To me, this seems to be settled already, with a clear winner. That being said, exceptions will always be found.

What’s important to remember is that customer experiences are molded by both what we see and hear, but also by what we don’t.

As such, the environment and the prices seen around the product do matter. A price cannot be decided in a vacuum.

If every product is listed with prices ending with ,99, and ONE product ends in ,95, visitors will notice that product. And vice versa.

Businesses can also, over a longer period, change how customers perceive prices. Perceptions also change depending on the niche.

So, while all the data points to ,9 being better than any other number ending, your own situation in your niche might be different. It probably won’t be, but that possibility cannot be excluded.

If nothing else, go with ,9. If you notice that everyone else in the niche prices that way ,9, try the opposite.

The absolute best way to find the true answer to the question of what price ending you should use is the same as always. Test all the alternatives yourself, if you can. Set up a split test where all the other variables are equal, and run the numbers.

If the results you get indicate something completely different from what me or anyone else has written or said, trust your data.

Data doesn’t lie.
