401(k) vs IRA: Which Should You Fund First?
Written by NestEggTrack Editorial · Last updated: October 8, 2026 · 6 min read
Quick answer: A 401(k) is employer-sponsored, often with a matching contribution and higher limits, but a limited fund lineup. An IRA is opened independently with lower limits but far more investment choices. The usual order: capture the full 401(k) match first, then max out an IRA, then return to the 401(k) for anything extra.
Both a 401(k) and an IRA are tax-advantaged accounts built for retirement, but they differ in who offers them, how much you're allowed to put in, and how much flexibility you get. Here's how they actually stack up, and a simple order of operations for where your next dollar should go.
The core differences
| 401(k) | IRA | |
|---|---|---|
| Offered by | Your employer, if they sponsor one | Any brokerage, opened individually |
| Employer match | Offered by many employers — essentially free money up to a limit | Not applicable |
| Contribution limits | Considerably higher | Considerably lower |
| Investment choices | Limited to your plan's fund lineup | Broad — most stocks, bonds, ETFs, mutual funds |
| Tax treatment | Traditional (pre-tax) is the typical option; many plans also offer a Roth version | Traditional or Roth, your choice, subject to Roth income limits |
For 2026, the employee 401(k) deferral limit is $24,500 ($32,500 with the age-50 catch-up, or $35,750 for ages 60 to 63), and the IRA limit is $7,500 ($8,600 if you're 50 or older). These shift most years, so confirm the current figures on the IRS website before you file.
Why the match usually wins first
If your employer matches part of your 401(k) contributions, that match is about the highest-return, lowest-risk dollar you'll find anywhere in your financial life — an immediate return, as long as you stay long enough to be vested, that no IRA investment choice can reliably beat. Leaving a match unclaimed is usually the first thing worth fixing in a savings plan, regardless of which account is otherwise "better" for your situation.
Why an IRA is often worth adding next
Once the match is fully captured, an IRA tends to get attractive fast because of its much wider investment menu — a 401(k) plan might offer a dozen fund choices, while an IRA at a brokerage opens up nearly the entire public market. Fees are worth comparing too: depending on your plan, either account can come out cheaper, and over multiple decades the difference can add up.
A simple order of operations
- Contribute enough to your 401(k) to get the full employer match, if one's offered.
- Max out an IRA — Traditional or Roth, depending on your tax situation and eligibility.
- Go back to the 401(k) and push contributions further, up to its higher limit, if you're able to save more.
This isn't a universal rule — someone without an employer match, or with a genuinely strong 401(k) fund lineup, might reasonably order things differently. But it's a solid default if you're building a plan from scratch.
Either way, the growth math doesn't change
Whichever account or mix you land on, the underlying question is the same one our retirement calculator is built around: given what you're contributing monthly and the return you expect, will your projected balance actually meet your goal by the age you're targeting?

Quick Answers
Should I max out my 401(k) or IRA first?
Contribute enough to your 401(k) to get the full employer match first, since it's essentially free money. After that, maxing out an IRA often makes sense before adding more to the 401(k), given its broader investment choices.
Can I contribute to both a 401(k) and an IRA?
Yes. They have separate contribution limits, so you can contribute to both in the same year, up to each account's individual limit. One catch: if you're covered by a workplace plan, your income can limit how much of a Traditional IRA contribution you can deduct.
What's the main difference between a 401(k) and an IRA?
A 401(k) is offered through your employer, often with a matching contribution and a higher contribution limit, but a limited fund lineup. An IRA is opened independently at any brokerage, with a lower limit but access to a much broader range of investments.
