Free 401(k) Contribution Optimizer — Capture Your Full Match

Are you leaving free money on the table? About 1 in 4 Americans don't contribute enough to their 401(k) to get the full employer match — that's literally turning down a 50–100% return on investment. Use this optimizer to find your sweet spot.

How to use this tool

  1. 1

    Enter your salary and age

    Age determines if you qualify for the $7,500 catch-up contribution (50+).

  2. 2

    Set your contribution %

    How much of each paycheck you're putting in.

  3. 3

    Add your employer match terms

    e.g., '50% match up to 6% of salary'.

  4. 4

    See if you're capturing the full match

    We'll flag if you're missing free money.

Pro tips

  • Always contribute at least up to the full employer match — it's an instant 50–100% return.
  • After capturing the match, max out a Roth IRA next ($7,000 limit in 2024) — more flexibility than 401(k).
  • 2024 401(k) limit: $23,000 (under 50) / $30,500 (50+). Max it if you can — huge tax savings.

Frequently asked questions

What's a 401(k) match?

Your employer adds money to your 401(k) for every dollar you contribute, up to a limit. Common: 'we match 50% of your first 6%' = +3% of salary free.

Is the employer match taxed?

No — match is pre-tax and grows tax-deferred until withdrawal at retirement.

Should I do Roth or Traditional 401(k)?

Roth if you expect higher taxes in retirement (younger workers). Traditional if you expect lower taxes (peak earners).
