Get the Full Employer Match Before You Argue 401(k) vs IRA

Should you max out the 401(k) or fund an IRA first? The honest answer is neither. Get the full employer match first, then have the argument.

That is not a dodge. A match is an immediate, guaranteed return on money you were going to save anyway, and no fund pick, fee sheet, or clever allocation can compete with it. If your employer adds money when you add money, every dollar up to that limit is the best deal in your financial life. So ask one question before anything else: how much do I have to put in to get all of it? Then put in exactly that much, and only that much, until you have done the rest of the checklist.

The match is not a tiebreaker, it is the whole game

Your employer's match is the only money in investing that arrives with a thank-you note attached. A fund either goes up or down. A match just shows up because you did.

So the 401(k) versus IRA debate is really a debate about what happens after the free money. Get the match, then compare the two stores, because they sell roughly the same goods.

An IRA is usually the better store if your 401(k) menu is expensive or thin, meaning the funds charge a lot or there is no cheap, broad fund to hide in. You control the IRA. You pick the fund. Nobody in your employer's HR department picked it for you.

The 401(k) is usually the better store if your plan is cheap and good, or if you like the tax deduction and the autopilot, since the money leaves your paycheck before you see it. Automatic saving beats heroic saving every month of the year.

The order: match, then IRA if the IRA is better or cheaper, then back to the 401(k). Also ask whether the match is yours immediately or only after you stay a while, because a match you forfeit by leaving is not a match.

Fees are a silent tenant

None of this matters as much as the fee line, the one page nobody reads.

Run the arithmetic. Add $500 a month for 30 years and earn 8% a year before fees. With a 0.05% yearly fee, you end with about $738,000. With a 1% yearly fee, you end with about $610,000. The higher fee costs about $128,000. That is not a rounding error. It is a Honda, or a year of college, or every vacation you will take for a decade.

Now look at the same plan with no fees at all: $500 a month for 30 years at 8% a year, before taxes and fees, ends at about $745,000. You put in about $180,000. The growth on top is about $565,000. Compounding does the heavy lifting, which is exactly why a fee that skims a slice off the growth is so expensive. The rule of 72 makes the point quickly: divide 72 by a yearly return to estimate doubling time, so at 8% a year money doubles roughly every 9 years. Shave the return and you shave the doublings.

The check takes ten minutes. Find the expense ratio of each fund on your 401(k) menu, which is the yearly cost written as a percent of your money. If a cheap broad fund is there, use it. If the menu is all expensive stuff, that is your argument for the IRA.

The bracket decides traditional versus Roth

The other decision hiding inside the account order is tax treatment.

A traditional 401(k) or IRA takes money before tax. You get the deduction now and pay income tax when you withdraw. A Roth is funded with money that was already taxed, and qualified withdrawals in retirement are tax-free.

So the question is not which is better in general. It is which is better for you, and that depends on your bracket now versus your honest guess at your bracket later. In a high bracket, with lower income expected later, the traditional deduction is worth more. Early in a career, in a low bracket, paying tax now for tax-free money later is a reasonable trade. Guessing is allowed. Being wrong is survivable, since most people end up with both kinds of account anyway.

One warning label: taking money out of a traditional IRA or 401(k) before age 59½ usually means income tax plus a 10% penalty, with some exceptions. That is the price of grabbing money the government has not taxed yet.

Your next step: one index card, three lines

Line one: the percent of my paycheck that earns the full employer match. Line two: what my 401(k) funds cost per year, as a percent, and whether a cheap broad fund is on the menu. Line three: my tax bracket now, and my guess for later. Look up the current contribution limit yourself instead of trusting a number from a column, including this one. Limits get updated. The checklist does not.

And remember what the account shuffle can and cannot do. The 4% rule, from research in the 1990s, found that withdrawing 4% of a stock-and-bond portfolio in your first year of retirement, then raising that amount with inflation, lasted at least 30 years in most historical periods. Flipped around: save 25 times your yearly spending. No fund menu fixes a savings rate of almost nothing. Set the contribution once, forget it, and go back to your life. The account order is worth one afternoon. The savings rate is worth everything.
