Target-Date Fund Statistics (2026)

Target-date funds have quietly become the center of gravity in American retirement saving. At the end of 2025 the total market was about $5.2 trillion, including $371 billion in custom strategies built for large plans (see the table below).

The core mutual-fund and collective-trust series grew 21% in 2025 to $4.8 trillion, powered by both rising equity markets and steady 401(k) contributions. A single fund-of-funds now holds a saver's entire retirement allocation and rebalances it automatically over time.

The growth has been relentless. Morningstar puts 2025 asset expansion at about 20%, and over the past decade target-date strategies have compounded at roughly 12% a year, a mix of market appreciation and consistent inflows.

That trajectory turned a niche 1990s product into a multi-trillion-dollar default. The shift accelerated after the Pension Protection Act of 2006 blessed target-date funds as a qualified default investment alternative, letting employers auto-enroll workers straight into them.

The plumbing has changed as much as the size. Collective investment trusts, the bank-sponsored, plan-only cousins of mutual funds, now hold about 54% of target-date assets, up from 52% a year earlier, having passed mutual funds in 2024 (Morningstar).

CITs win on cost and flexibility for large retirement plans, which is why every one of the 20-plus new target-date series launched in 2025 was a CIT. Many simply mirror an existing mutual-fund lineup at a lower price point.

The market is strikingly concentrated. Vanguard alone manages about $1.79 trillion, or 36.9% of all target-date assets, followed by Fidelity ($693 billion), BlackRock ($611 billion), T. Rowe Price ($585 billion), and Capital Group ($429 billion) (see the chart and table below).

Together the top five hold 81.1% of mutual-fund and CIT target-date assets, up slightly from 80.8% three years earlier. Vanguard also led growth in 2025, adding about $35.9 billion, ahead of Capital Group and State Street.

To see why they matter, look at the system they sit in. US retirement assets hit a record $49.1 trillion at the end of 2025, with $14.2 trillion in defined-contribution plans (including $10.1 trillion in 401(k)s) and $19.2 trillion in IRAs (see the table below).

Within that, ICI counts about $1.6 trillion of hybrid funds (a category dominated by target-date funds) in 401(k) plans and $1.2 trillion in IRAs. Because ICI's hybrid bucket is broader than TDFs alone, treat these as close proxies rather than exact totals.

Adoption is now near-universal where the option exists. In 2024, 96% of Vanguard plans offered a target-date fund and 84% of participants used one when it was available (see the table below).

More striking is how completely people rely on them: 67% of participants held their entire account in a single professionally managed allocation, 60% in one target-date or balanced fund, and among target-date investors specifically, 73% put their whole balance in a single dated fund (Vanguard).

Automatic enrollment is the engine behind these numbers. About 61% of Vanguard plans automatically enrolled new hires in 2024, up from just 10% in 2006, and almost all of them route that default money into a target-date fund.

That design turns inertia into an asset: a worker who never makes a single investment choice still ends up in a diversified, age-appropriate, auto-rebalancing portfolio. It is the main reason target-date use keeps climbing even as markets wobble.

Target-date adoption skews young because new hires get defaulted in. ICI and EBRI data show participants in their twenties hold close to 90% of their 401(k) balances in equities and roughly two-thirds in target-date funds, versus about 57% equities and one-third in TDFs for those in their sixties.

Recently hired workers have long over-indexed on target-date funds relative to veterans, and once in, they tend to stay: more than 90% of savers fully invested in a TDF at year-end 2019 were still fully invested four years later (ICI/EBRI).

Costs have collapsed as scale and index competition took hold. The asset-weighted expense ratio for target-date mutual funds fell to 0.27% in 2025 from 0.29% in 2024, and is down roughly 48% over the past decade to about half its former level (see the chart and table below).

Morningstar notes the 2-basis-point drop across more than $2 trillion in target-date mutual funds saved investors over $80 million in 2025 alone. The cheapest series now cost well under 0.10%, while the most expensive active lineups can still run 0.50% or more.

The cost story mirrors an index-versus-active split. As of 2025, index (passive) strategies held about 53% of target-date assets, active series about 42%, and blended portfolios roughly 5% (see the chart above).

Passive lineups such as Vanguard Target Retirement and Fidelity Freedom Index dominate on price, but active managers like T. Rowe Price and American Funds retain large followings by pitching stronger long-run returns and more tactical glide paths.

A glide path is the schedule that shifts a fund from stocks toward bonds as the target year approaches. Most start near 90% equity for young savers and step down over decades; Vanguard, for example, lands around 50% equity at the target retirement date (see the table below).

The key design choice is 'to' versus 'through.' A 'to' fund reaches its most conservative mix at the retirement date, while a 'through' fund keeps derisking for 10 to 20 years afterward. Vanguard, Fidelity, T. Rowe Price, and BlackRock LifePath all use 'through' paths, so two 2030 funds can hold very different stock weights.

The newest frontier bolts guaranteed income onto the glide path. Assets in target-date strategies with embedded income (often annuities) rose 39% in 2025 to about $139 billion, up from roughly $100 billion at the start of the year.

The leaders are TIAA RetirePlus ($72 billion), BlackRock LifePath Paycheck ($27 billion), State Street IncomeWise ($22 billion), and AllianceBernstein's Lifetime Income Strategy ($14 billion). The pitch is a paycheck-like stream in retirement, addressing savers' fear of outliving their money.

Performance has largely validated the design. Morningstar found that investors in 2025-dated funds earned about 7.3% annualized over the roughly 15-year cycle studied, capturing a strong equity run while the glide path trimmed risk near retirement.

Because target-date holders rarely trade, they also tend to avoid the behavior gap that hurts do-it-yourself investors who buy high and sell low. Automatic rebalancing forces the discipline most people struggle to maintain on their own.

A target-date fund is a reasonable, low-effort default: one ticker gives you a diversified, age-appropriate, auto-rebalancing portfolio for as little as 0.08% to 0.15% in the cheapest index versions. For many savers, that beats a self-built mix they neglect.

The trade-off is one-size-fits-most. The fund knows your retirement year, not your risk tolerance, outside assets, or tax situation, and two funds with the same date can hold very different stock weights. If you want the low-cost core but more control over the mix, a thesis-driven basket lets you keep the simplicity while tuning the exposure.
