How Much One Can Earn From A Facebook App

I was very curious knowing how much one can earn from a facebook app. I come up, the earning from Facebook app depends on following factors:

1. How many active users you app have. Active users are those who use your app daily, for example if you have 20,000 users but only 1000 use it daily, the active users are 1000.

2. In which economy (or country) your facebook app users are.

Here are some facts shared by a very successful Facebook apps developer,

"1. If your apps can attract around 1000 unique users per
day with atleast 60 % from High earning countries(HEC) like
Autralia, US, UK and Canada , you can make around 10$ per day.
2. 10000 unique users with 60-70% from HEC will earn you around 40-50$ per day
3. 15000 unique users —> 90-100$ per day
4. 35000 unique users —> 150-200$ pd
5. 45000 unique users —-> 250-350$ pd
5. 60000 unique users —-> 400-600$ pd
6. 1.2 lakhs unique users— 1000-1500$ pd"
