Just came acros this while working, thought it may serve you as a motivational boost. No one knows it for sure, but here are some estimated earnings:

Google generates $691.27 per second! Isn't it crazy? And the annual revenue is $21,800,000,000. If you have taken 5 seconds to read this post then Google would have already made around $3456.34 in between.
