Using Ally as an example, you need $15k (I believe) to get their High Yield Savings which is 1.9% and the national average is 0.04%.

So taking $15k you would earn (in 1 years time):

15,000 * 0.04% = $6.00 in interest
15,000 * 1.90% = $287.50 in interest

Yes it is definitely a higher number, but is $281.50 worth it to you?

If it is, then go for it!

But I think we sometimes think that even a high yield savings account is going to make some significant difference in our financial lives but when you run the numbers it isn't as significant as we initially thought.
