How much does BB Ki vines earns?

The estimated number is at the end, jump directly there if you are not interested in the theory!

Youtube does not pay for the views you get, it pays for the monetized clicks on the ads that are displayed during your video is played.

What is the difference? Youtube does not display ads on every view! So if your video is played 1000 times and ads are displayed 100 times and clicked 5 times out of that hundred impressions, you will be paid for 5 clicks. This is not a theory but the fact.

Besides, there are pay-per-view ads that are played before your video starts. Here, you are paid based on total add impressions rather than clicks. So if your video is played 1000 times and an ad appeared in the beginning 100 times, you are paid for those 100 impressions.

Value of these clicks and impressions [the price paid to the channel owner] is not same for every user. A user clicking on add from USA will reward you much-much higher than a user/viewer clicking from India.

So you see, Youtube income can be really uncertain each month, based on the performance of the channel.

Now the real thing:

Let us assume that Youtube pays $1 per 1000 views. [a rough but nearly valid estimation, based on indian audience’s cost-per-click/impression].

By the time you are reading this answer, BB has crossed 4M subs on his channel. And each of his videos is getting at least 1 crore views.

1000 views = $1

10000 views = $10

100000 views = $100

1000000 views = $1000

10000000 views = $10000

$10000 = 6,00,000 INR

So, here is your answer: BB is earning 6 lakh indian rupees for each of his videos crossing 1 crore views mark, cheers.

Note that adsense is not his only source of income.
