I know at some point your investments start snowballing. When did you actually start seeing the snowball rolling?

Previous threads discussing this:

At What Dollar Level Does the $$ Start Compounding Fast?High net worth mustachians: when did your money really start to grow?When did you notice the compound interest snowball?That should give you lots of comments/discussion on this topic, and if you want more, do a search, I'm sure there's more. :)

I'll second matchewed--my graph always looked linear. Due to the fact that your net worth as a Mustachian, when you have a high savings rate, is dominated by your contributions, not returns, your graph WILL look linear. That's okay, that's a good thing. That means you're saving a lot.

You won't snowball much, just have a linear on the way to hitting FI (you may finally, towards the end, have your stache contributing as much as you are), but it's those returns that will let your FIRE stache last the rest of your life. You can run the math, or do a search to see where people have posted it, on what % of your stache is made up of contributions versus returns, based on your savings rate, but the vast majority, when you have a high savings rate, is contributions. IIRC (off the top of my head) it's something like 85% contributions, 15% returns with a 70% SR. That may be off, but it's a pretty big discrepancy like that.
