Outlander is one of the biggest shows on all of television, and it has legions of fans around the world. It's had its problems like any other show, but over time, people have come to know it inside and out, and they've appreciated every aspect of it. There's still a lot to look forward to on the show, and fans cannot wait to see what's in store.

The biggest stars on the show have been making some solid money, increasing their wealth over time. Only one star can lay claim to the highest net worth, and we have the details below!

'Outlander' Is A Huge Show

August 2014 marked the debut of Outlander on STARZ. The show, which was based on the ongoing novel series by Diana Gabaldon, was an instant success on the network, and since then, it has developed into a powerhouse on the small screen.

Starring an amazing cast led by Caitriona Balfe and Sam Heughan, the historical fiction show has been a breath of fresh air during its eight years on the small screen. Ronald Moore was responsible for developing the show, and he was able to hit a home run with what he was able to do with Gabaldon's source material.

As it stands now, we are currently in the sixth season of the show. Impressively, a seventh season, which should have around 16 episodes, has already been confirmed. This means that fans are going to be eating good for quite some time.

While this is all great, things got even better when a prequel series that will be focusing on the parents of Jamie Fraser was announced. It'll be a while before it comes together, but fans can't wait.

Outlander's success means big paychecks for the stars, and two cast members are ahead of their colleagues in the net worth department.

Caitriona Balfe Is Worth $4 Million

At the number to spot on the net worth list is Caitriona Balfe, the primary star of the series. The actress has been a revelation during her time on the show, and according to Celebrity Net Worth, she currently sports a net worth of $4 million.

The site not only talked about her net worth, but it also highlighted her accomplishments, as well.

"From 2012 to 2013 she starred as Breanna Sheehan on the TV series H+. Balfe has starred in the films Super 8, Lost Angeles, Crush, Now You See Me, Escape Plan, The Price of Desire, and Money Monster. In 2016 and 2017 she was nominated for Golden Globe Awards for Best Performance by an Actress in a Television Series – Drama for Outlander. Balfe won Saturn Awards in 2015 and 2016 for Outlander and also won a BAFTA Award, Scotland in 2016 and People's Choice Awards in 2016 and 2017," the site wrote.

Due to the show's success, some huge opportunities have been coming the actresses way. Just last year, she starred in Belfast, which was nominated for Best Picture at the Academy Awards. As you can imagine, she was fantastic in that movie.

Caitriona Balfe's $4 million net worth is impressive, but it falls just short of the person who holds the top spot.

Sam Heughan Is Worth $5 Million

Coming in at the top spot on the list is none other than Sam Heughan, who plays Jamie Fraser on the show. According to Celebrity Net Worth, the actor is currently worth a solid $5 million, and as Outlander continues its incredible success on the small screen, we imagine that this number will only continue to increase.

When dishing on the actor's accomplishments, the site wrote, "Heughan had recurring roles as Philip Dorr on the TV mini-series Island at War in 2004 and as Andrew Murray on the series River City in 2005. He has appeared in the movies Young Alexander the Great, Emulsion, Heart of Lightness, and When the Starlight Ends. Heughan has also acted in stage productions of Outlying Islands, The Vortex, Hamlet, Romeo and Juliet, Macbeth, Plague Over England, and King John. From 2011 to 2012 he starred as Batman in the touring show Batman Live. In 2017 he won a People's Choice Award for Favorite Sci-Fi/Fantasy TV Actor."
