I am trying to work something out (please forgive me for being thick!!).
If you invested £3000 and in ten years time it paid me £5,500. What would be the annual interest be each year. Apologies again if there is an easy formula. Please can anyone give me (a) the answer and (b) the formula. I am trying to compare it against known interest rates of other banks/ica's etc.

The answer is 6.25% AER
A = Initial deposit
B = Final amount
N = Number of years
Then the interest rate is found by (B / A)^1/N
which in your example gives 1.0624888 from which you subtract 1 and multiply by 100 :beer:

Assuming you're using the standard windows calculator you'll need to put it in scientific mode by clicking view and then scientific to use the ( ) and ^ functions:
Press the open bracket ( button
Type in 5500
Press the divide / button
Type in 3000
Press the close bracket ) button
You should see 1.83 with the 3 recurring (in other words 1.833333333333333333).
Press the power ( x^y ) button
Press (
Type 1
Press /
Type 10
Press )
Press Equals =
Answer will be 1.062488.... For the actual percentage:
Press minus
Type 1
Press equals
Press multiply
Type 100
Press equals
6.2488.... which is 6.25 to two decimal places.
