Up until now I've only really had one account (discounting a building society account which has zero rewards or offers so I transferred everything out of it ages ago) I do everything from, banking, savings, transfer monies etc (purchases are done with CC and paid back from the main account).
I just thought about taking some of it out and putting it into a savings account to benefit from some of the new rewards they have on offer at most banks.
Reading about it I'm still a tiny bit confused, basically I am trying to find the catch if there is any, I'm no banking guru, I'm just person 12345 using the money I make each month on bills, expenses and purchases whilst saving the rest I notice many places offer high interest rates with rewards if you make no withdrawals each month so basically you're getting free money based on x percent of what is sitting in the savings account at the end of that month.
My math is not as good as it used to be but say for example you transferred £4k into a savings account offering 4.10% interest (not gross) I figured that after a typical month the total would be based on the following calculation:
Current balance in savings account divide by 100 multiplied by interest percentage = A
Then
Sum of A and interest percentage = B (Total interest at end of month)
So £4000 / 100 * 4.1 = £164
£164 + 4.1 = £168.1
= £4168.1 in your account at the end of that typical month
Or is this completely wrong?!
I ask here because I just got notified of a new reward scheme by my bank when logging in online and you apply online too.
Does anyone else have such an account for long term purposes ?
Sounds like a nice way to have some extra free cash put into your account each month !

I guess I'll have to keep in thought the future benefits then and just go for it and slowly buildup the deposits into the account over time!
