Snapchat's revenue totals could climb to $1 billion in 2017, which is up 1,594% from Snap's 2015 revenue totals of $59 million.

That growth is incredible, but investors still want to know, "how does Snapchat make money?"

Snapchat has three main revenue sources right now.

And through its biggest revenue source, Snapchat can charge advertisers as much as $750,000 per day for a single advertisement…

How Snapchat Makes Money

Snapchat's biggest revenue source right now are "Sponsored Lenses." This feature allows Snapchat users to take a video or picture of themselves with different animations added to the shot.

For example, Taco Bell worked with Snapchat to create a sponsored lens for May 5, 2016 (Cinco de Mayo). The lens let users turn their head into a taco.

In just one day, Taco Bell's lens received 224 million views, according to Adweek.

20th Century Fox also created a sponsored lens in conjunction with the launch of "The Peanuts Movie" in 2015.

Through the lens, Snapchat users could add characters from the movie, like Snoopy and Woodstock, to their photos and videos.

And because of their popularity, Sponsored Lenses aren't cheap…

For holidays and special events like the Super Bowl, Snapchat Lenses can cost up to $750,000. During a nonpeak day, lenses can cost $450,000 or more, according to Financial Times.

Snapchat also has a similar product on a smaller scale for individuals and companies. Snapchat's "Geofilters" are ad-like invitations that allow other Snapchat users to know where a concert, fundraiser, or event will be held.

According to eMarketer, Snapchat was projected to make $102 million from branded lenses and Geofilters in 2016.

Snapchat is still developing its second revenue source. But it's already so popular that Snap wanted to renegotiate terms with advertisers a year and a half after it launched…

Snapchat Makes Money with "Discover"

Snapchat launched "Discover" in January 2015. Through Discover, companies like ESPN and CNN can create snaps in the form of a short story.

Snapchat was charging its partners on Discover roughly $100 per thousand views of their story, according to. For ad revenue, Snapchat took 30% if the media company sold ad space within its story.

If Snapchat sold the ad space, it took a 50% cut.

But in October 2016, Snapchat wanted to change the terms for Discover partnership. This is an indication the advertising demand for Snapchat is growing.

According to Recode, Snapchat wanted to pay content partners upfront license fees, sell all the ads on its own, and keep all of the ad revenue.

In 2016, eMarketer projected Snapchat would generate nearly $250 million in video ad revenue.
