You’re spending way more time on Facebook than you think.

Around 890 million people visit Facebook daily, and they’re devoted. Between tagging photos, liking statuses, chatting with friends, and arguing about think pieces, users are spending around 50 minutes each day on Facebook and its Instagram and Messenger platforms, Facebook told the New York Times last year.

And those fifty minutes can cost you. Nearly one in three Americans say that social media has an influence on their purchasing decisions, and many admit to buying a vacation or something else because they saw someone post about it on social media, Marketwatch reported last year.

But whether you buy things because of social media or not, you’re likely using it for a specific reason. Indeed, a study released this week from researchers at Brigham Young University found four distinct types of Facebook user. Take our quiz to find out which one you are (the descriptions are below the quiz) — and how you can reduce your Facebook use (and thus possibly help save your self some money), depending on which type you are.

Type 1: Relationship Builders
For these users, Facebook hour is social hour. Relationship builders share photos with their friends, connect with each other on messenger, and like and comment on each other’s content to maintain their social circles. They also use it as an organizational and time-saving tool for their personal life, managing their calendar with the Events tool, finding the newest events on their newsfeed, and posting announcements to avoid having to call or email friends and family.

The fix: If you’re a relationship builder who spends too much time on social media, try using the Chrome extension Stylebot to hide your news feed, while still displaying chat, birthdays, and profiles. You won’t get distracted by excess content, and you’ll still have the basics that you need.

Type 2: Town Criers
You probably know a town crier–their opinions are all over your news feed. They prefer not to use Facebook as a personal communication tool, opting to communicate with close family and friends by other means. Instead, they view Facebook like a street corner: a place to announce, and to connect with people who agree. They enjoy the attention they get from social media, but draw a hard line between social media contacts and the offline world.

The fix: Take some time each Sunday to schedule all of your posts and announcements for the upcoming week–then you’ll have six days with no reason to visit the site.

Type 3: Selfies
As their moniker implies, selfies use Facebook for self-gratification. These users edit their photos and albums to show a glamorous image to the world. They live for the likes they receive on their photos, videos, and statuses, and spend much more time curating their own content than they do viewing that of others. Selfies are the most common type of Facebook user.

The fix: Try the Chrome extension Facebook Nanny: It blocks you from visiting the site unless you have notifications. You’ll be able to enjoy your likes and comments, but be forced to step away from the screen in between.

Type 4: Window Shoppers
According to the study, window shoppers are the smallest Facebook demographic. This group enjoys Facebook from a distance. They don’t post much content of their own, opting to spend most of their time rifling through the profiles of others, or “Facebook stalking.” While they recognize the social importance of having a Facebook profile, Window Shoppers prefer to remain grounded in the real world.

The fix:  If you spend too much time Facebook stalking, try to limit your Facebook visits to Friday and Saturday afternoons and evenings. This is when the fewest people are online, says software engineer Dr. Nwokedi Idika on her blog, and the time when you’ll find the least interesting and new content to grab your attention.
