@OP - Its kind of a pointless comparison to simply ask what your net worth was at any given age, simply because everyone's circumstances are different and sometimes the market does things you simply can't control.
Personally at 22 I had a net worth of 30k, worked full time making about 35k a year at the time, and went to school part time(paid cash as I went), had just paid cash for a 2 year old car with low miles so I had a reliable car for the near future, and still lived with my parents. I put a good chunk of that money into a down payment for a condo so I didn't have to pay PMI or throw money away at rent(cost about the same to own as rent after the down payment). Seemed like a great place to be at the time considering most of my friends at the time were getting ready to graduate college, had tons of student loans to worry about, and if they had a job, it was like an 8 dollar an hour part time gig.
Fast forward a couple years and the real estate market crashed and the economy tanked. My condo that I had paid 85k for, that I could have sold for 90-100 a year later, was now worth about 40k. It really sucked at that point having a net worth of around 40k and suddenly I'm back down to 0. I ended up graduating around this time as well...only the economy was crap and I was having a hard time finding a job better than what I already had, so I went back for another degree...not really where I wanted to be in my mid-late 20s, but I just hadn't been able to catch much of a break anywhere even though I was working hard and most of my money to date went to real estate and education.
Fast forward again a few more years to 30...my net worth was probably only around 40k at this point. This was definitely a lot lower than I had wanted it to be...but 30 was the year things really turned around for me. The value of my condo had recovered a bit and after 8 years of rents increasing and my mortgage getting cheaper thanks to a refi, I was now living in a place and building equity(instead of trying to not be underwater anymore lol) that costs 600 a month vs 800-900 renting something similar in the area. I was totally done paying for school with no student loans whatsoever to pay back. Best of all I finally landed a better job that literally tripled my income. I went from 40k a year to about 90-100k this year, and next year(first full year at the new job) I'll be 120k+.
So here I am now...at 31, with a net worth of 100k, a six figure income, and a monthly expenses of around 1200 a month. I was in crappy shape when I turned 30, and now, even though my net worth isn't stellar for a 31 year old mustachian(although its ridiculous for your average 31 year old) I'm in a pretty awesome position. I'll probably pay off the condo this year which will cut my monthly expenses to below 1000 a month. I'll literally be able to live off 10% of my gross, and if I want to buy a house in the near future my condo just becomes a paid off rental property, plus all the time I had spent in a lower paying job thankfully had built me up a significant chunk of time in a pension fund, so even though I wouldn't really count that towards my net worth its still some extra retirement income I'll get to enjoy when I'm 64:)
Had my only goal been to have a high net worth at 30 I'd have never gone to college. I'd have just gotten a part time job on top of my full time job instead of going to school, and invested all that extra money. Had I done that I probably would have been around 300k by 30...but ultimately I'd have ended up being 31 making 50-60k a year at a job I hated with 300k net worth instead of being 31 making 120-140k a year at a job I enjoy with 100k net worth, and I'd still be doing labor work beating on my body instead of what I do now that doesn't involve any repetitive or heavy lifting. Its just like people on here who have gone to school for law or medical degrees. I don't think they mind their net worth sucking at 30 when the only reason it sucks is because they spent 8-10 years getting to a point where they could actually start their career and had lots of student loans to pay back. Much like my situation they all could have been doing better at 30 if they aimed for that, but would they have been better at 35 or 40?
Plus we have some other factors that basically make comparisons pointless. I know plenty of people who had parents or grandparents that are(were) very well off and were gifted/inherited significant assets and/or had college paid for. I think its awesome when people have 300k+ by 30, but its really not serving any purpose to compare someone who was maybe handed a house and had their college paid for to someone else of the same age who had to pay for those things on their own. My living grandfather, whom I hope has many, many happy and healthy years left to go, is a multi-millionaire, and plans of splitting it between his grand kids when he passes away as his kids are all doing well for themselves. I could very easily inherit several hundred thousand next month if something happens to him, but I don't think it really makes me good at handling my finances or a better mustachian because I might end up 32 with a 500k+ net worth even though most of it was just handed to me, just the same as if he had died when I was 30 and I had a 500k+ net worth at 30.
I'd think the best measure of comparing your mustachian skills, way more than net worth at any given age, is what is your savings rate? At least then things are being compared that we all have to work equally hard at...our spending habits and our income, and ultimately its the people who can master these things that are the ones who will have successful early retirements.
