How do they work out the interest? doesnt look like you can earn a great deal on any of them really?

    The £113 interest figure depenads on how they've calculated the interest out.

    Most low-risk savings accounts are all going to have crap rates at the moment due to the base rate being so low.

    with that 7% account, even though its an ISA, as far as I can work out they seem to be calculating the interest monthly rather than anually, which is what many banks do with these "headline" rates. So basically rather than working it out of 7% of £3000, its calculated like this.
    MONTH 1 - £250, so you work out 7% of that, add it on, (£17.50)
    MONTH 2 - £517.50, 7% Of that, etc..
    I think thats how they work it anyway, kinda like compound interest that u learn in school

    Nearly, i think you would work it out like this:

    Month One: £250 (Work out 7% which is £17.50) then divide by 12 (the amount of months in a year) = £1.45 times 12 (the amount of months this £250 will be in the account when the interest is paid out) = 17.5

    TOTAL = £267.5


    Month Two: £250 again work out the 7% which is £17.50, then divide by 12, then this time times by 11 since this £250 will only be in there for 11 months. so the interest earned on this £250 will be £17.50 / 12 = £1.45 * 11 = 16.04 so that £250 will be £266.04

    you do this for each individual £250 , each time reducing the final multiplication of the monthly interest rate, then adding the values all up at the end.

    The only way for that 7% interest rate to equate to 7% of the £3000 that you've saved is if you invest it as a lump sum £3000 in the first month.
