If your YouTube channel has 500 subscribers, you will earn $10 to $1000 per month depending on the number of videos you post regularly. The income is partially dependent on the number of subscribers but the most important thing is the quality of your videos.
Assuming that you post 10 videos per month, at least 100 of them will view each of the videos. This means that from your subscribers, you will get 1000 views. Some of the subscribers will share the videos and in total you might get 10,000 views per month. If you get 10,000 views, YouTube will pay you $10 and above.
The 500 subscribers is the minimum threshold for YouTube monetization. The number was reduced from 1000.This number of subscribers is low, it may not generate significant revenue.
Also, the amount of money earned from 500 subscribers is determined by the niche of your content. Content related to personal finance, web hosting, making money online, loans, mortgage and entertainment generate the highest amount of money.
To earn more money, even more than $100 per 500 subscribers, target traffic from USA.
