Any experience with maxing out 401(k)?
You want to take the hit now.   There are tons of calculators out there, but the rule of 70 should be enough to help convince you: Assume you can put an extra $10k in a 401k now, or keep it.  If you pay ~30% in taxes, you  can have either: A) $7k now, or: B) What $10K will grow to in your 40 years till retirement less taxes at the end. The rule of 70 is a quick, dirty way to calculate compounded returns.  It says that if you divide 70 by your assumed return, you get the approximate number of years it will take to double your money.   So let's say you assume a 5% rate of return (you can replace that with whatever you want): 1) 70/5 is 14, so you'll double your $10k every 14 years. 2) In 40 years, you'll double your money almost 3 times (2.86) 3) That means you'll end up with almost $80k before taxes 4) Even if we assume the same tax rate at retirement of 30% (odds are decent it's lower, since you'll have less income, presumably), you still have $56k. Whatever you think inflation will be, $56k later is a LOT better than $7k now.
