Im very new to investing but after doing some reading Ive opened an account with self wealth and thinking about building a portfolio based on vanguard australia balanced ETF. I know this probably sounds like a very newby question but can someone please give me a rough approximation of what my portfolio might be worth in 10 years if I invest 100k and reinvest everything plus add an extra $15k a year? If I build my own portfolio how do I continue to keep it balanced? Is there some kind of automation than can keep the percentages balanced? Or am i better off using a robo invester if im unsure?
