I mean, I never said it's life changing money. OP's question was about different ways to get money, and earning interest off of your savings in a high yield savings account gets you some money with almost no effort. Not to mention it's better than having your money sit in a regular savings account earning 0.05% or something. It's a pretty good way to save up for something in the short term, like if you plan to buy a new laptop or phone in a few months.
It can range from between 4% and 5%+. Per nerdwallet, the highest they have listed is 5.07%. I'm not good at math and how bank rates work, but you can probably try computing based on those percentages.
