How much return did you get on your first year of investing?

Hi anon, each individual's returns will differ according to the type of investment made, when it was made, etc.

Instead of looking at that, you may want to look at the average returns of each asset class.

If you want to invest in US stocks, for example, over the past 10 years (as of 24 Feb 2020), the S&P 500 index has produced an annualised return of 11.8%. That return would be slightly lower now with the current stock market jitters. However, it shouldn't differ too much from the average.
