With 9 number one singles in her native country, Katy Perry is undoubtedly one of the biggest hit makers of the past 10 years. She shaped the digital era alongside artists like Rihanna, Adele, Taylor Swift, Bruno Mars & Maroon 5.
Has this success managed to translate into other metrics? We’ll find out shortly enough!
Katy Perry started her mainstream career in 2008 after multiple unsuccessful attempts. She was dropped from two different record labels which resulted in multiple albums getting scrapped.
One of the Boys turned things around for the pop diva, shifting multiple smash hits such as I Kissed a Girl and Hot n Cold. The album sold well enough, but not enough to turn her into a household name just yet.
Two years later in 2010, she released her second mainstream effort, Teenage Dream.
This album remains the most successful released by the singer and broke several records, most notably becoming the first woman, and second artist overall following Michael Jackson, in the history of the Billboard Hot 100 to send five songs from an album to No. 1.
Together with its release, the record spawned a total of six number one hits, most notably signature hits like California Gurls, Firework and the title track, Teenage Dream.
In 2013, the pop diva released her third mainstream effort, PRISM. The album, while considerably less successful than its predecessor, was still among the top albums of the year and managed to spawn multiple number one hits for Katy Perry, including signature hits like Roar and Dark Horse.
Four years later in 2017, the pop star came back with a new record, as well as a new image. Her fourth mainstream effort, Witness, was widely considered as one of the biggest flops of the year. Did it bomb as badly as has been claimed? We’ll find out below.

The Commensurate Sales to Popularity Concept (CSPC)
There are two ways to understand this revolutionary concept. In the first place, there is this Scribe video posted below. If you are unaware of the CSPC method, you will get the full idea within just a pair of minutes.
If you are a mathematical person, and want to know the full method as well as formulas, you can read the full introduction article.
Now let’s get into the artist’s sales figures in detail in order to apply this concept and define the act’s true popularity!
Katy Perry’s Album Sales
Original Album Sales – Comments
Often, Katy Perry‘s success has been disregarded because of her relatively weak album sales against her incredible single sales. Her peers, such as Adele, Lady Gaga, Taylor Swift and Rihanna, are all past 30 million pure album sales compared to Perry‘s 15.28 million.
While it’s true that pure album sales aren’t exactly Katy Perry‘s biggest strength, her first three mainstream efforts didn’t sell badly by any means, as they’re among the best sellers of their respective years.
Witness was a massive decline for the pop diva, selling only 14% of its predecessor, PRISM, in spite of ticket concert bundles in North America.
Katy Perry’s songs sales
As a reminder, the weighting is done with a 10 to 3 ratio between one album and one physical single.
As with all stars from her generation, Perry sold the huge majority of her singles in digital format leaving very little space for physical sales.
As a prime example her debut single, I Kissed A Girl, sold a mere 28,000 CD singles in the UK out of an overall 750,000 units total, less than 4% of its sales.
And that’s her debut single, the one with the most favorable market context!
Up to an incredible 135 million digital downloads, the most unbelievable fact is that she did so with mostly three album eras.
Her main 12 singles from them add for a whopping 108 million.
I Kissed A Girl, Hot N Cold, California Girls, Firework and Roar sold over 10 million each, making the diva the only female artist ever with 5 songs past 10 million units sold. Teenage Dream, E.T. and Dark Horse are all fairly close too.
The era of Teenage Dream as a whole is up to a stunning 65,85 million copies, the second most prolific era of all-time in this format, only topped by Lady Gaga‘s The Fame.
Witness fails to do well in this format with only one million selling song, Chained To The Rhythm.
Streaming is made up of audio and video streams. Our CSPC methodology includes both to better reflect the real popularity of each track. The main source of data for each avenue is respectively Spotify and YouTube. To factor in the growing impact of multiple Asian countries where these platforms aren’t always the go-to site for music streaming, more sources have been added.
In order to account for their real popularity in each relevant country, the below sources have been used along with the mentioned ratios that reflect the market share of each area.
– South Korea : Genie streams * 3.05 (consistent with Gaon streaming numbers)
– Japan : AWA streams * 100/5.5 (AWA has 5.5% of the Japanese streaming market)
– Elsewhere : Spotify streams * (370 – 8.5 – 9.5 – 33 – 9) / 207 (370 million global subscribers minus 8.5 million from South Korea minus 9.5 million from Japan minus 33 million from China divided by the number of Spotify only users minus 9 million more Asian users) + Genie streams * 3.05 (uses Genie rather than Spotify to extrapolate markets like Taiwan, Thailand and Vietnam)
– China* : Xiami streams * 125/6.5 (Xiami has just over 5% of the Chinese streaming market)
– Elsewhere : Youtube views
*since 96.4% of Chinese streaming platforms are free users, that paid-for users pay less than $2 a month and that they are also used as video streaming platforms, their streams are weighted in par with YouTube streams.
Audio Stream value – 1500 plays equal 1 album unit
Video Stream value – 11,750 views equal 1 album unit
Equivalent Albums Sales (EAS) = ( Spotify * 310/207 + Genie * 3.05*2 + AWA * 100/5.5 ) / 1500 + ( Xiami * 125/6.5 + YouTube ) / 11750
Streaming is one metric Katy Perry heavily benefits from, besides digital sales. As we can see in the breakdown above, 19 of her Top 20 tracks have reached at least 100 million plays on Spotify and no less than 300 million views on YouTube.
Her two biggest tracks, Dark Horse and Roar, are responsible for 1.6 million EAS for PRISM.
Surprisingly enough, her third biggest track is not a song from Teenage Dream or One of the Boys, but a collaboration with Calvin Harris, Pharrell Williams, and Big Sean instead.
Despite only charting at No. 20 in the US, the track was big enough globally to become the American artist’s most streamed track on Spotify to date, with 621 million streams.
Firework is the top track from Teenage Dream and her fourth biggest song overall, accumulating over half a million EAS. Three more tracks from the album are inside the pop diva’s personal Top 10 – all ranging from 500k to no less than 284k EAS.
Witness was the first of these albums to be released during the streaming era, so it’s not surprising to see the three singles rank high, with the lead single, Chained to the Rhythm, accumulating nearly half a million EAS for the album.
As the record was released in 2008, tracks from One of the Boys do not rank as high as the rest, for obvious reasons. I Kissed a Girl and Hot N Cold still manage to do well in this format with 258k and 242k EAS, respectively.

Katy Perry’s compilations sales
It sounds fairly logical to add together weighted sales of one era – studio album, physical singles, downloads, streams – to get the full picture of an album’s popularity. For older releases though, they also generate sales of various live, music videos and compilation albums.
All those packaging-only records do not create value, they exploit the value originating from the parent studio album of each of its tracks instead. Inevitably, when such compilations are issued, this downgrades catalog sales of the original LP.
Thus, to perfectly gauge the worth of these releases, we need to re-assign sales proportionally to its contribution of all the compilations which feature its songs. The following table explains this method.
The distribution process
Here is the most underestimated indicator of an album’s success – the amount of compilation sales of all kinds it generated. Due to the dependency of sales of the original studio albums on these releases, they are a key piece of the jigsaw.
How to understand this table? In the example of MTV Unplugged, these figures mean it sold 125,000 units worldwide. The second statistics column means all versions of all the songs included on this package add for 336,031 equivalent album sales from streams of all types.
The second part on the right of the table shows how many equivalent streams are coming from each original album, plus the share it represents on the overall package. Thus, streaming figures tell us songs from the One of the Boys album are responsible for 99% of the MTV Unplugged track list attractiveness. This means it generated 124,000 of its 125,000 album sales and so forth for the other records.
Total Album (all types) Sales per Country
Please note country-specific numbers may miss sales of a few minor releases, although totals are complete.

It isn’t surprising to see Teenage Dream as Katy Perry‘s top album. What may be surprising to some is the fact it’s now nearing 20 million sales across all formats.
Since the last update in March 2018, it has gone from barely 19 million to over 19.7 million, proving tracks from this album are still relevant in 2019. Teenage Dream is the 5th most successful album of the decade only topped by Adele‘s and Ed Sheeran‘s last two outputs and we can expect it to hit the magical 20 million mark before the end ot the year.
Another record that will soon reach is a new important milestone is her mainstream debut, One of the Boys, at nearly 9.8 million EAS to date.
Since the last update, PRISM has now reached 11 million EAS. It remains to this day the most successful non-soundtrack album of 2013, overtaking records that sold more in original album format, such as Midnight Memories by One Direction.
Katy Perry‘s latest record, Witness, was saved from being a complete bomb by strong streaming numbers. It finally reaches the 2 million mark, exactly 2 years after its release. Still, this record marks a massive 80% decline from its predecessor, PRISM.
With a new album being allegedly on the way, one can only wonder if her career can fully recover.
The cumulative tally of Katy Perry is up to 45.4 million equivalent album sales – more than 2 million since the last update. This now puts her ahead of Avril Lavigne, NSYNC, One Direction and The Cranberries.
