@TechnicallyBehind I just had an SBI account in which salary used to get credited.
Took an HDFC bank account too for savings, and use the SBI for spending.
So I have one which is used for spending and the other as a savings account.
Apart from my monthly expenses I keep the rest in the other account. I invest some into mutual funds, but don’t put all the cash in MF/FDs.. and always have some liquid cash, since you don’t know when an emergency expense will pop up.
The reason why I did this is cause I spend too much on food, especially desserts. So when I started to keep separate accounts, I don’t have this thought that I have enough left, even if I splurge. It creates a false perception that I only have enough for this month.
And one more thing SBI bank servers are down frequently and sometimes becomes a problem for using UPI, HDFC is better.
