I plan to pay myself each month first when I receive my salary. What is the best account for savings? I'm considering between dbs multiplier and uob one?

Agree with Rais that you should maintain a separate account for 'paying yourself first'. Perhaps what you can do is to use a high yield savings account as the account to 'pay yourself', and transfer out the remaining amount into another account for your expenses. This way, you would still be able to earn higher interest on your savings while having a separate account for spending. With the revision for the DBS Multiplier account in Feb20, you could potentially earn an interest of 2%-2.2% on the first $50k with 2 categories fulfilled, while UOB One's EIR is 2.43% if you meet both conditions.

If you are going to pay yourself first, you should consider transfering this money to a completely separate account where it is a little more difficult no access and has no ATM card.

I believe most of the salary crediting high interest account is not an option since you will be using them for receiving your salary.

Consider using CIMB FastSaver account. It gives at least a 1% interest and is a completely separate account without an ATM card.
