What is the TER in an index fund?
The TER (Total Expense Ratio) represents the total annual percentage in fees automatically deducted from your accumulated wealth by the fund. The lower the TER, the more return you keep.
What is the difference between index funds and ETFs?
Index funds are traded once a day at their closing net asset value and enjoy tax neutrality in Spain (you can transfer money between them without triggering capital gains taxes). ETFs trade in real time like stocks and are not always eligible for tax-free transfers.
