I opened up this account 30th January and during February I paid in the minimum amount and 2DDs came off. It was sitting with a balance of Â£5003. I got my first interest yesterday of Â£11.27. Is this right as I thought 3% of Â£5k was Â£150 /12 would be Â£12.5 a month. I'm happy with this compared to my is a but is my sums wrong.
