Well, if interest rates for savers increase by 1% pa and you maintain a balance of £1000 your interest will increase by £10 a year before tax.
You can adjust this for your own savings and projected interest rate increases.
I'd be surprised if interest rates for savers increase by more than 1% in 2011.
savers have not had any returns on there savings for a couple of years so its about time interest rates went up so as we can get a little back for a change..
