Your 401(k) came with a login — not a manual.

What you'll learn
- How a 401(k) actually works — the deferral, the match, and where the money goes
- Why the employer match is part of your pay, and how to collect all of it
- Roth vs. pre-tax in plain English: pay tax now, or pay tax later
- What vesting means before you change jobs — and what a rollover protects
- The 2026 limits — $24,500 for 401(k)s, $7,500 for IRAs (IRS) — and why a steady percentage beats a perfect number
Key concepts, in plain English
- The employer match
- Money your employer adds when you contribute — '100% of the first 3%' is typical plan language. It's part of your compensation, not a bonus. Contributing below the match cap means leaving pay unclaimed every single payday.
- Roth vs. pre-tax
- Pre-tax contributions cut your tax bill today and are taxed when withdrawn. Roth contributions are taxed today, and qualified withdrawals — including the growth — are tax-free under current law. Your bracket now versus later is the deciding question; a tax professional can help with the close calls.
- Vesting
- The schedule on which employer contributions become permanently yours. Your own contributions are always 100% yours; the match may vest over several years. Worth checking before you accept a new offer — a few months of timing can change what you keep.
- Target-date funds
- A single fund that gradually shifts from growth-focused to conservative as your chosen retirement year approaches. A reasonable default for hands-off savers — just check the fees and make sure the date on the label matches your actual plan.
- Auto-escalation
- A plan feature that raises your contribution rate a little each year, automatically. Research on retirement 'nudges' shows these small automatic raises meaningfully increase savings — you do nothing, and you save more.
- Accumulation vs. withdrawal
- Your retirement account lives two lives: decades of putting money in, then decades of taking it out — with different rules and risks in each phase. Social Security joins in the second phase. For most people it's a foundation, not the whole plan, and your claiming age changes the size of the monthly check.
Myth vs. fact
Myth
I'm young — retirement can wait.
Fact
Waiting is the expensive choice. Money contributed in your 20s has decades for compound growth to potentially work; the same dollars contributed in your 40s simply have less time.
Myth
Skipping the match is no big deal.
Fact
A dollar-for-dollar match doubles each matched dollar the moment it lands, subject to vesting. Skipping it is declining part of your pay.
Myth
If I change jobs, I lose my 401(k).
Fact
Your own contributions are always yours. Employer money depends on the vesting schedule, and the whole account can move with you through a rollover — without taxes, when done correctly.
Myth
Social Security will cover my retirement.
Fact
It was designed as a foundation, not the full structure. For most people it replaces only part of their working income — the rest comes from what they've built.
