The 56-year-old performer earlier this month published a video to direct social media users’ focus to her most popular Christmas song which was first released in 1994.

The video, titled “It’s Time”, continued with her annual tradition on Nov. 1 to remind the world of her classic song, which has been viewed 825 million times for the last 16 years on YouTube.

“All I Want for Christmas Is You”, which currently ranks top on Billboard’s Holiday 100 list, paid her $60 million in royalties when it was first released three decades ago, according to Forbes.

But the number does not stop there. The Economist estimates that she fetches around $2.5 million in annual royalties from the song, while The New York Post pegs the figure at around $3 million.

Law firm Manatt, Phelps & Phillips estimates that the song has generated a total of $103 million globally since its debut, from sources like streaming, album sales and song downloads.

As the song’s performer, co-writer and co-producer, Carey likely receives a large proportion of that revenue, it added.

Songwriters and publishers in the U.S. receive royalties when a song is played publicly on TV, radio, or in restaurants and stores.

This means Carey collect royalties each time a cover of “All I Want for Christmas Is You” is played publicly. More than 150 performers have recorded versions of the song, according to performing rights organization ASCAP.

Last year, Spotify said that the pop song was the first-ever holiday song to surpass 2 billion global streams.

It had been the No. 1 song globally on Christmas Day each year since 2016, Spotify said.

Carey has been hailed as one of the “greatest singers of all time” by music magazine Rolling Stone. The five-time Grammy winner has 19 songs that have topped the Billboard Hot 100.

She told ABC News earlier that the song stems from her desire to create an iconic piece of music for Christmas.

“My goal was to do something timeless, so it didn’t feel like the ’90s, which is when I wrote it,” she said.

“I was working on it by myself … on this little Casio keyboard and writing down words and thinking about, ‘What do I think of at Christmas? What do I love? What do I want? What do I dream of? And that’s what started it.”
