Long-term investors, what kind of annual returns have you actually seen?

Hi everyone. I’m fairly new to investing and started about a year ago. I’m trying to get a realistic idea of long-term expectations over 10-15 year timeframe. For those of you who have been investing for 5, 10 years or longer with a well-diversified portfolio using ETFs and other assets like stocks, gold, or similar, what kind of average annual returns have you seen over time, not adjusted for inflation? Rough estimates are totally fine.
