@neilarch I agree this would be nice to see as I have to manually calculate the increase based on deposits.
I think the difficulty is that typically I am making monthly contributions which would dilute the % increase from the original deposit. For example if I put £1,000 as my original deposit and it grew by 7% over the month I would now have £1,070 (ex fees). If I then placed in another £1,000 in the second month that growth would have dropped from 7% directly to 3.5% as I have doubled the initial deposit even though 50% of the fund did not benefit from the previous months growth.
I am sure there is a economic method for this calculations, but I don’t think its as simple to have a straight formula based on growth / total contributions.
Perhaps a end of month statement would be a better option that would show total fund growth for the month along with deposits and withdraws.
