If you focus on a dividend paying ETF like DVY, the median dividend yield is 3.5% annually. That means you’ll need about $8.57 million to achieve a dividend yield of $300,000.

But a “return” doesn’t necessarily mean dividend only. You will also experience growth, so you can sell some of your investments as well. If you use the 4% rule (meaning you pull out 4% of your account value annually to meet your goal of $300,000), you can have about $7.5 million in investments.
