I don't have the Early Access to Banking DLC but, you may want to do more research on how interest rates work in the game based on some of the pictures I have seen in the Bank DLC Features. The Interest Rate on Savings/CD Accounts Seem way too high.
Savings Account Rate is 7% in one Picture i saw. When it should be more like ~3.75% Based on my Estimates below.
