Retirement Planning
Your future self is counting on you. 401(k)s, IRAs, Roth vs Traditional, employer matching, and exactly how much you actually need to retire — explained without the jargon.
The $1.2 million mistake sitting in Dave's inbox
Dave was 28, working as a software developer in Austin, making $95,000. His company offered a 401(k) with a 100% employer match up to 6% of his salary. For three years, Dave hadn't signed up. Not because he couldn't afford it — because the enrollment form felt complicated and he kept saying "I'll do it next month."
That procrastination cost him. His employer would have matched $5,700 per year — free money. Over three years, Dave left $17,100 in employer contributions on the table. But the real damage was worse: accounting for compound growth over the 37 years until retirement, that missed match alone would have grown to roughly $450,000.
Multiply that pattern across a full career of not contributing? Dave was on track to retire with approximately $1.2 million less than he could have had — just because a form felt annoying.
The retirement account cheat sheet
Retirement accounts aren't complicated — there are really only a few types that matter, and they each have one job: help you save for retirement with tax advantages.
| Account | Who offers it | 2025 contribution limit | Tax benefit | Key feature |
|---|---|---|---|---|
| Traditional 401(k) | Your employer | $23,500/year ($31,000 if 50+) | Tax-deductible now, taxed when you withdraw | Often has employer match |
| Roth 401(k) | Your employer | $23,500/year ($31,000 if 50+) | No deduction now, but withdrawals are tax-FREE | Pay taxes now, enjoy tax-free growth |
| Traditional IRA | You open it yourself | $7,000/year ($8,000 if 50+) | Tax-deductible now, taxed on withdrawal | Available to anyone with earned income |
| Roth IRA | You open it yourself | $7,000/year ($8,000 if 50+) | No deduction now, withdrawals are tax-FREE | Income limits apply ($150K+ single, $236K+ married for 2025 — phase-out ranges) |
(Contribution limits are for 2025 tax year; they increase periodically — check IRS.gov for current limits)
Roth vs Traditional: the $200,000 decision
Let's make this concrete. Assume you invest $500/month for 30 years at 10% average returns:
| Traditional (tax-deferred) | Roth (tax-free) | |
|---|---|---|
| Monthly contribution | $500 (pre-tax) | $500 (after-tax) |
| Portfolio at 65 | $1,130,244 | $1,130,244 |
| Taxes owed at withdrawal (est. 22% bracket) | ~$248,654 | $0 |
| Money you actually keep | ~$881,590 | ~$1,130,244 |
The Roth advantage: $248,654 more in your pocket. And this is conservative — if tax rates increase by the time you retire (many economists expect they will, given government debt levels), the Roth advantage grows even larger.

There Are No Dumb Questions
"What if my employer only offers a Traditional 401(k), not Roth?"
Many employers now offer both — check with HR. If yours only offers Traditional, contribute enough to get the full employer match, then open a Roth IRA on your own (at Fidelity, Schwab, or Vanguard — takes 15 minutes) and contribute up to $7,000/year there.
"Can I contribute to both a 401(k) and an IRA?"
Yes. The $23,500 401(k) limit and $7,000 IRA limit are separate. If you can max both, that's $30,500/year in tax-advantaged retirement savings. Most people can't max both early in their careers — start with the 401(k) match, then fund a Roth IRA, then go back and increase 401(k) contributions.
Employer matching: the only guaranteed 100% return
If your employer matches 401(k) contributions, not contributing enough to get the full match is leaving free money on the table. There is no investment on Earth that guarantees a 100% return. An employer match does.
Common match structures:
| Match type | What it means | On a $80,000 salary |
|---|---|---|
| 100% match up to 3% | Employer matches dollar-for-dollar on first 3% | You put in $2,400, employer adds $2,400 |
| 50% match up to 6% | Employer matches 50 cents per dollar on first 6% | You put in $4,800, employer adds $2,400 |
| 100% match up to 6% | Dollar-for-dollar on first 6% | You put in $4,800, employer adds $4,800 |
Find Your Free Money
25 XPHow much do you actually need to retire?
The most common question — and the most anxiety-inducing. Here's a straightforward framework.
The 4% Rule
The 4% rule (from the 1998 Trinity Study, updated with subsequent research) says: if you withdraw 4% of your retirement portfolio in your first year, then adjust for inflation each year after, your money has historically lasted at least 30 years about 95% of the time.
Working backwards:
Step 1: Estimate your annual retirement expenses. Most financial planners suggest 70-80% of your pre-retirement income. If you earn $80,000/year, plan for $56,000-$64,000/year in retirement.
Step 2: Subtract guaranteed income (Social Security, pension). The average Social Security benefit is about $23,000/year (as of 2025). So you might need $64,000 - $23,000 = $41,000/year from your portfolio.
Step 3: Multiply by 25. If you need $41,000/year from your portfolio, you need $41,000 x 25 = $1,025,000 saved. That's your target number.
| Annual spending need | Minus Social Security (~$23K) | Amount needed from portfolio | Retirement savings target (25x) |
|---|---|---|---|
| $40,000 | $17,000 | $17,000 | $425,000 |
| $60,000 | $37,000 | $37,000 | $925,000 |
| $80,000 | $57,000 | $57,000 | $1,425,000 |
| $100,000 | $77,000 | $77,000 | $1,925,000 |
Retirement savings target by annual spending
There Are No Dumb Questions
"A million dollars?! I'll never save that much."
Remember compound interest. If you invest $500/month starting at age 25 with 10% average returns, you'll have about $1.13 million by 65 — and you only contributed $240,000 of that. Compound growth does the heavy lifting. The million-dollar number sounds intimidating, but $500/month is achievable for many professionals.
"Can I count on Social Security?"
Social Security is projected to be solvent through approximately 2033, after which the trust fund reserves may be depleted and benefits could be reduced to roughly 77% of scheduled amounts if Congress takes no action (Social Security Board of Trustees, 2024 report). It will almost certainly exist in some form, but planning to rely on it fully is risky. Treat it as a supplement, not your plan.
The priority order: where to put your money
Priority 1: Get the full employer 401(k) match. This is free money — a guaranteed 100% return. Do this before anything else.
Priority 2: Build your emergency fund. 3-6 months of expenses in a high-yield savings account.
Priority 3: Pay off high-interest debt. Credit cards at 20%+ should be eliminated before extra investing.
Priority 4: Max out a Roth IRA ($7,000/year). Tax-free growth is incredibly valuable. Open one at Fidelity, Schwab, or Vanguard.
Priority 5: Increase 401(k) contributions toward the max ($23,500). Once you've handled the above, pour more into your 401(k).
Priority 6: Taxable brokerage account. If you've maxed all tax-advantaged accounts, invest additional money in a regular brokerage account.

50 XPKey takeaways
- Not contributing enough to get your employer's full 401(k) match is the most expensive mistake in personal finance. It's a guaranteed 100% return.
- Traditional = tax break now, pay taxes later. Roth = pay taxes now, withdrawals are tax-free. Most young professionals should lean Roth.
- 2025 contribution limits: 401(k): $23,500. IRA: $7,000. Both limits are separate — you can contribute to both.
- The 4% rule tells you how much you need: multiply your annual retirement spending (minus Social Security) by 25. That's your target.
- Priority order: employer match → emergency fund → pay off high-interest debt → Roth IRA → max 401(k) → taxable brokerage.
- Compound growth does the heavy lifting. $500/month at 10% for 40 years = $2.6M, of which you only contributed $240K.
