Nothing beats retirement savings. If I knew at age 28 what I know now, I would live in my car so I could max out my 401K contribs. Match or not!
You cap out at $19,500, your employer is contributing another $19,500. That's $39,000/year toward retirement. Doing this so early in life will assure you a respectable retirement. The advantage you have is indescribable.
Not least, it is merely thrifty to max out that 100% match while it is available to you. You sure won't get it most places.
401Ks are a fortress
Life may have its misadventures. But a 401K (and IRAs in certain states) are a fortress of invulnerability. Funds in a 401K cannot be forcibly taken from you. Not by bankruptcy and not by lawsuit. To me more precise, they're not quite yours -- they are a fund held in trust for your benefit at retirement. Unlike most trust funds, you can violate that for a relatively low consequence - 10% (and then, of course, paying the tax, assuming it's not a Roth, which has taxes prepaid).
So even if you suffer a life calamity that drives you to insolvency or bankruptcy, do not liquidate 401K assets to try to pay down debts. Make the creditor wait, or declare bankruptcy: the 401K will ride through completely intact.
Student loans are also not clearable in bankruptcy (at least, not so far). But ironically, that means you should not rush to pay the student loan while other basic financial needs exist. For instance an emergency fund is more important than rushing down student loans. Put it this way, the debt "isn't going anywhere" lol.
How urgent is it to max, really?
Now, does "not having fully funded your 401K" qualify as "financial stress"? That's a good question. I would say, having witnessed the power of compounding, and the sadness of missing the opportunity at a young age when it matters the most, yeah -- definitely.
Every dollar you put in at age 28 is $8 you don't have to put in at age 49. It's actually possible at your age to max your IRA for 12 years, then stop altogether, and never contrib another dollar. **That means you're not in your 40s scrambling to play catch-up with your 401(k), in a game you have (effectively) already lost. So yeah. Some ramen-eating today amounts to caviar in midlife, nevermind what it does for you in retirement.
Of course, the young won't appreciate this :)
