InvestEngine's management fees are calculated daily and deducted from your account on a monthly basis, usually a few days after the end of the month. You will be able to see the fee being deducted as a transaction in your dashboard.
ETF fees are taken at source by the ETF companies (such as Vanguard and iShares) who manage the ETFs we use to invest your money. Fees vary for different ETFs but the average in our Growth portfolios is 0.15% a year, and 0.25% in our Income portfolios. You won't find these fees in any transactions listed on your dashboard because they are built into the ETF's performance but they should be considered in the overall annual cost of your investments.
