Getting 1 million YouTube subscribers is a huge milestone, and, in practical terms, it often means a creator can earn a full-time living from the platform.

Nate O'Brien, a YouTuber with more than 1 million subscribers, earned $440,000 from the platform in a year. He earned from $14,600 to $54,600 a month.

To start earning money directly from YouTube, creators must apply for the Partner Program and meet a threshold of 500 subscribers, three public uploads in the last 90 days, and either 3,000 watch hours in the past year or 3 million YouTube shorts views in the past 90 days. Once accepted, eligible creators can earn money from features such as channel memberships, Super Chat, Super Stickers, Super Thanks, and the ability to promote their products with YouTube Shopping.

To start earning money from YouTube AdSense, creators in the program must have 1,000 subscribers and 4,000 watch hours in the past year.

Two key metrics for earning money on YouTube are the CPM rate, or how much money advertisers pay YouTube per 1,000 ad views, and the RPM rate, which is how much revenue a creator earns for every 1,000 video views after YouTube's cut.

Some subjects, like personal finance and business, can boost a creator's ad rate by attracting lucrative advertisers. But while Ma's lifestyle content makes less money, she's perfected a strategy to maximize payout.

"To really optimize your audience, I think YouTubers should definitely put three to four ads within a video," Ma said.
