How is a 30-day yield calculated?

It does not take into account the effect of changing share prices on the total return. The 30-day yield is calculated by taking the fund's interest and/or dividend earnings for the most recent month and dividing by the average number of shares outstanding for the month times the highest share offer price on the last day of the month.

Does Robinhood gold have a good interest rate?

Robinhood's 4.15% interest rate is hard to beat. It's more than 12 times the average national interest rate on savings accounts based on the FDIC's figures, and even better than many high-yield savings accounts. However, non-subscribers to Robinhood Gold only earn 1.5% interest on uninvested deposits.

What's the difference between a 30-day yield and a distribution yield?

However, they're not the same. The 30-day yield uses the past 30 days of dividend and interest income to project the fund's income for the next 12 months, while the distribution yield takes the most recent distribution -- whether interest, dividends, or capital gains -- and multiplies that payment by 12 to get an annualized total.
