Just an illustrative estimate in NZD. It assumes you invest regularly at the return you picked and ignores fees and tax; the "today's money" view only adjusts for the inflation rate shown. Returns aren't guaranteed and past performance isn't a promise about the future. This is general info to help you learn, not personalised financial advice — for your own situation, chat to a licensed financial adviser.
