<prompt> Human: Say I have 40,000 USD... the monthly pay seems more like 32. I hardly ever withdraw from the account, so the balance consistently grows. Yet the monthly interest is significantly lower than 1. I understand they dont calculate based off the monthly balance; they have another formula for it which is: Account Balance x Interest Rate 365 days x number of days at that balanceBut I still dont get it. Also: Is having more than 1 online savings account better than 1 fat hog?  <response>: 40,000 1 400 per year, or 33 per month.
