Auto-enrollment handed you a default fund at 25 and you never looked back, but the investment your employer chose for you may already be working against your timeline and draining returns you will never recover.

You were auto-enrolled in your 401(k) at 25, checked a box, and moved on. Five years later, you still own whatever target-date fund the plan defaulted you into, and you have never once opened the prospectus. You are not alone. By year-end 2025, 61% of Vanguard defined contribution plans had adopted automatic enrollment, and 99% of automatic enrollment plans used a target-date or other balanced investment strategy as the default fund, with 98% choosing a target-date fund. That default is fine, but it is not optimized. If you want to graduate from “whatever they picked” to a portfolio a grown-up would actually build, three ETFs do the job: Vanguard Total Stock Market ETF (NYSEARCA:VTI), iShares Core Dividend Growth ETF (NYSEARCA:DGRO), and Vanguard Total Bond Market ETF (NASDAQ:BND).
Why the Default Fund Is Costing You
At face value, target-date funds are convenient. They glide from stocks to bonds automatically as you age. The catch: the specific target-date series inside your plan menu was chosen by your employer, not you, and plan-menu share classes frequently carry higher expense ratios than the retail ETFs available in a brokerage IRA. On top of that, a 2065 or 2070 fund may already hold a meaningful bond sleeve you do not need at 25. One clean fix is an IRA rollover from a former employer plan, since ETFs like these three are often unavailable inside an active 401(k) menu but sit right there in any IRA.
VTI: The Entire US Market in One Ticker
VTI owns essentially every investable US stock, tracking the CRSP US Total Market Index. That single fund gives you Apple, NVIDIA, the S&P 500, and thousands of mid- and small-caps in one line. Performance backs the strategy: VTI is up 11.9% year-to-date and 17.9% over the past year, with a 234.13% ten-year gain. It also pays you while you wait, with quarterly distributions totaling $3.8999 over the trailing 12 months and an annualized forward figure of $4.1748. At $375.17 a share, this is your growth engine.
DGRO: Quality Compounders That Raise the Check
Where VTI is the whole market, DGRO screens for US companies with a record of growing dividends, tracking the Morningstar US Dividend Growth Index. That tilts you toward mature, cash-generative businesses. Its expense ratio is 0.08%, which means you keep $992 of every $1,000 working for you. Returns have kept up with the broad market: DGRO is up 14.67% YTD, 20.36% over one year, and 253.01% over ten years, and the trailing 12-month distribution total is $1.477673, paid quarterly. Think of DGRO as a quality overlay to VTI, not a replacement.
BND: The Shock Absorber You Do Not Yet Need Much Of
At 25, your bond allocation should be small, but it should not necessarily be zero if you plan to add money in a downturn without flinching. BND holds thousands of investment-grade US bonds tracking the Bloomberg US Aggregate Float Adjusted Index, and it does so absurdly cheaply. Its expense ratio is just 0.04%. The fund pays monthly, with a trailing 12-month total of $2.91731 and an annualized forward distribution of $3.0192. Bonds are not the story right now: BND is down 0.8% YTD and up just 1.2% on the year, but that is the point. It moves differently from stocks, and a 10% to 20% sleeve keeps you from panic-selling VTI in the next drawdown.
One Trade-Off Worth Naming
Building your own three-fund portfolio means you have to rebalance it. Nobody glides your allocation for you the way a target-date fund does. If you know you will never log in again, the default fund may actually be the better answer, because behavior beats optimization. But if you are willing to spend twenty minutes a year, VTI plus DGRO plus a modest BND sleeve gives you total-market growth, a dividend-growth tilt, and a genuine shock absorber, at costs the plan menu almost certainly cannot match. That is the grown-up version of the account you have been ignoring.
