IRA vs 401(k) - which to fund first
What you'll learn
Learn the standard funding order - 401(k) to the full match, then the IRA, then back to the 401(k).
Fund the 401(k) up to the full employer match first, then fill the IRA, then go back to the 401(k). That is the standard order, and each step earns its place.
- Step 1: 401(k) to the match. Matched dollars are an instant 50% or 100% return before any growth. Nothing else in investing pays that on day one, so this dollar always goes first.
- Step 2: fill the IRA. With the match banked, the IRA usually wins the next dollar: any broker, any fund, typically lower fees, and Roth IRA contributions can be withdrawn penalty-free if life goes sideways.
- Step 3: back to the 401(k). The 401(k)'s employee deferral limit is roughly three times the IRA's, so it soaks up everything after the IRA is full - with payroll automation doing the heavy lifting.
| Step | Where the dollar goes | Why it wins that slot |
|---|---|---|
| 1 | 401(k), up to the match cap | Instant return from employer money |
| 2 | IRA, to its annual limit | Fund choice, lower fees, flexibility |
| 3 | 401(k), toward its limit | The biggest remaining tax-advantaged space |
The order is a priority list, not a quota
Few people fill all three steps, and that is fine. The point is direction: a dollar in step one outworks a dollar in step three. Contribute what you can, in this order, and step it up when pay rises.
The 2026 limits used in the chart ($7,500 IRA, $24,500 401(k) employee deferral) are the IRS's published figures, but they change most years - check the current numbers in our Roth IRA vs 401(k) guide, which covers the full sequencing argument.
Key takeaways
- The order: 401(k) to the full match, then the IRA, then back to the 401(k).
- Matched dollars always come first - they earn an instant return nothing else offers.
- The IRA wins the second slot on fund choice, fees and flexibility.
- It is a priority list, not a quota - partial progress in the right order still wins.
Illustrative only, not a forecast or a recommendation. Assumes a $60,000 salary, a 50%-of-6% match and 2026 IRS limits ($7,500 IRA, $24,500 401(k) employee deferral). Limits change - check the current figures. Few people fill every step; the order matters more than the totals.
Frequently asked questions
Why not just fill the 401(k) first and skip the IRA?
You can, but an IRA usually offers things the workplace plan cannot - any broker, any fund, often lower fees, and with a Roth IRA the ability to withdraw contributions penalty-free. The order grabs the match, then buys that flexibility, then returns for the 401(k)'s bigger limit.
What if my employer offers no match at all?
Then step one disappears and many savers start with the IRA for its fund choice and lower costs, before using the 401(k) for its much larger contribution limit. The 401(k)'s payroll automation is still valuable either way.
Do I have to fill each step before moving on?
No. The order is a priority list, not a set of quotas. Most people never fill every step - the point is that a dollar aimed at step one works harder than a dollar aimed at step three.
Should the IRA in step two be traditional or Roth?
It depends on whether your tax rate is higher now or in retirement - the same trade-off covered in the IRA lesson. Roth contributions also phase out at higher incomes, so check the current thresholds.
