Edit: Oops, I read age 45 as 35. My mistake. Let me update my numbers (I think ~45-50% is for 20 years, no? If it's not, please just fill in)
Rough numbers: If you make $60k and want to retire in 20 years, you're looking at having to invest roughly 50% of your salary each year. If your income doesn't change, you're looking at $30k of your money each year. Which means living off $30k a year, or $2,500 a month and FIRE'ing at that amount as well.
Or, if your expenses don't change(~40k a year), you'd have to adjust your income to a combined level of about $80k+ a year for the next 20 years.
You're definitely within striking distance with a few tweaks to either your budget or your incomes (my original post for FIRE at 35 was a bit less optimistic, sorry lol)
All that being said, here's what I recommend:
1) Put just enough into your 401(k) to get the match
2) Max both of your ROTH IRA's. Your income is low enough to not really be a factor, so a ROTH will be a better play for you at your income level.
3) Continue with your 401(k),
3) Do as much of the cost savings/revenue increases (second job?) that you can. A lot of high-income areas have high-paying side jobs like dog walker, uber/lyft driver, etc.
All that said, kudos to you for tackling this at 25. You're leaps and bounds above most people by taking a quantitative approach to this problem so early.
