401k Usa

Hey everyone!

I’m just starting to wrap my head around this whole 401k thing and had a few questions. I’ve recently started my first full-time job and they offer a 401k plan. I get that it’s a retirement savings account, but I’m trying to understand how to really make the most of it.

Employer Match: My employer matches contributions up to a certain percentage. How exactly does this work? Is it worth contributing beyond that match limit or should I focus my extra savings elsewhere?
Investment Options: How should I go about choosing which funds to invest in within the 401k? Is it smart to be aggressive when I’m young, or should I be more conservative? The variety of options is a bit overwhelming.
Fees: Are there hidden fees that I should be aware of in my 401k plan? How do I find out what they are and assess if they’re reasonable?
Roth vs. Traditional: How do I decide whether to contribute to a Roth 401k vs. a traditional one? Is one better for someone just starting out?

Any insights, tips, or resources you guys can share would be incredibly helpful! Thanks a bunch!

A few non-obvious 401k gotchas to check before you set it and forget it:

Match details: look up the vesting schedule and whether your plan “true-ups” the match. If there’s no true-up, don’t front-load contributions early in the year or you can miss match dollars on later paychecks.
After-tax + in-plan Roth: see if the plan allows after-tax contributions and immediate in-plan Roth conversions (aka “mega backdoor Roth”). If yes, that can be more powerful than a taxable account once you’ve hit the standard deferral.
Fees: don’t just look at fund expense ratios. Add plan-level admin fees, any wrap or advisory fees, and revenue sharing. You’ll find them in the 404a-5 disclosure and your quarterly statement. Compare the “all-in” cost of your chosen lineup vs a target-date fund.
Brokerage window (SDBA): can be great for low-cost ETFs, but some plans tack on asset-based or per-trade fees that wipe out the benefit. Read the SDBA fee schedule closely.
Cash option: if you keep any cash in the plan, check the stable value fund’s credited rate and exit restrictions-it often beats the plan’s money market.
Company stock: keep it modest. You’re already tied to your employer for income; don’t double down in the retirement plan.
Roth vs. traditional: early-career often tilts Roth, but run the numbers with your current marginal tax rate, state tax now vs where you might retire, and whether traditional contributions help you qualify for the Saver’s Credit or other benefits. Some plans now let employer matches be Roth (taxable now) if you opt in.
Coordination: if you have an HSA-eligible plan, prioritize HSA after the 401k match. Also, if you might do backdoor Roth IRAs in the future, avoid rolling old pre-tax IRAs into an IRA-roll them into a 401k to keep your IRA balance clean for the pro-rata rule.
Glide path: target-date funds aren’t all the same. Check the underlying fees and equity allocation; some are weirdly conservative or pricey.

None of this requires heroics-just read the SPD/annual fee notice, set auto-escalation, and avoid the easy fee/match traps.
