401(k) vs. IRA vs. Roth: The 5-Minute Version
Tax-advantaged accounts are the closest thing to free money in personal finance.
Retirement accounts are not investments themselves — they are tax-advantaged containers you put investments inside. Used in the right order, they can add up to a meaningfully larger nest egg simply by saving on taxes.
The two tax flavors
- Traditional (pre-tax): You contribute money before tax, lowering your taxable income today. It grows untaxed, and you pay ordinary income tax when you withdraw in retirement. Good if you expect a lower tax rate later.
- Roth (after-tax): You contribute money you have already paid tax on. It grows tax-free, and qualified withdrawals in retirement are completely tax-free. Good if you expect a higher tax rate later — often the case for younger savers early in their careers.
The main accounts
- 401(k): Offered through an employer. Higher contribution limits, and often an employer match — free money. Contributions usually come straight out of your paycheck.
- IRA (Individual Retirement Account): You open it yourself at a brokerage. Lower contribution limit than a 401(k), but far more investment choice. Comes in Traditional and Roth versions.
A sensible order of operations
For many people, the priority looks like this:
- Capture the full employer match in your 401(k). A 50% or 100% match is an instant, guaranteed return you cannot beat elsewhere.
- Pay down high-interest debt (credit cards).
- Fund an IRA — a Roth if you are eligible and expect higher future taxes.
- Return to the 401(k) and contribute more, up to the annual limit.
Two rules to remember
- These accounts are for the long term — withdrawing early often triggers taxes and penalties.
- Contribution limits reset each year and tend to rise over time; check the current year's figures.
The takeaway
Always grab the employer match first — it is the best deal in finance. Then use a Roth or Traditional IRA to keep more of your growth away from taxes. The account you choose can matter almost as much as what you invest in.
