<a href="https:&#x2F;&#x2F;socialblade.com&#x2F;youtube&#x2F;" rel="nofollow">https:&#x2F;&#x2F;socialblade.com&#x2F;youtube&#x2F;</a>   Is a pretty good tool for this.<p>I have some friends who are &quot;professional YouTubers&quot; (big enough to quit their day-jobs, not big enough to buy a Ferrari), who have told me they use that site for refernce.  The estimate it gives has a pretty wide range, but it&#x27;s typically in the middle of the two extremes. Just searched for one of my friends, and averaging the estimate gives just slightly more than what he&#x27;s making in a month from YT.<p>Of course, it&#x27;s all really variable and depends on the size of your channel. In January he had a video go viral and made as much as he did in all of 2015, but has since gone back to his more regular numbers (growing a little every month).
