401k Vs Roth Ira
401(k) vs Roth IRA is primarily a tax-timing and eligibility story: deferrals now vs tax-free growth, income limits, employer match, and investment menus. The Compare Strategies engine does not replace a full tax plan, but it helps you reason about marginal dollars once you know your match and bracket.
Quick answer
Capture any full employer match first — it is often a higher return than equivalent-risk alternatives. Between Roth and traditional, compare marginal tax rates and time horizon; use the tool’s other modes for invest vs debt once you have surplus cash.

How to use this calculator
- Confirm eligibility and limits: Income limits and plan rules change yearly — verify before deciding Roth vs traditional IRA.
- Pick the mode that matches the decision: Invest vs debt is not the same question as real estate vs stocks — do not mix modes.
- Align assumptions once: Return, tax drag, and horizon must be shared across strategies or the score is misleading.
What this page compares conceptually

Example: match vs Roth contribution
If match is 50% on 6% of salary, many households prioritize match before Roth — the “return” on match is often unmatched (illustrative).
Real-world example
- Use Advanced tax context elsewhere: For complex conversions, pair this with a tax professional — the engine focuses on modeled comparisons, not tax filings.

Usually match first, then Roth vs traditional based on bracket expectations — not a single universal winner.
FAQ
Why does the recommendation change when I tweak one input?
Because the model is sensitivity-based. Small changes near break-even points change the winner.
Is the “winner” personalized advice?
No — it is a modeled comparison from your inputs. Use it to structure questions for a professional.
Should I ignore liquidity?
No. Even when investing wins on paper, you may need cash buffers — the model does not replace an emergency fund.
