401(k) PlansAlmost every 401(k) offers the same building blocks under different names: large-cap, mid- and small-cap, an international fund, a bond fund, and a stable-value or money-market option. The "best" allocation is less about picking winners and more about how you weight those blocks as retirement gets closer.
Hold more in the stock funds (large, mid, small, international) when retirement is decades away, and gradually raise the bond and money-market funds as it approaches. The mixes below are illustrative starting points, not a prescription.
The framework: your allocation follows your time horizon
The most important variable is not this quarter's headlines — it is how many years until you need the money. Time is what lets a portfolio recover from downturns, which is why a 35-year-old and a 62-year-old should not hold the same mix. Here is an illustrative glide path.
| Stage | Large | Mid | Small | Int'l | Bond | Stocks |
|---|---|---|---|---|---|---|
| 30s · growth | 50% | 15% | 15% | 10% | 10% | 90% |
| 40s · build | 50% | 12% | 10% | 10% | 18% | 82% |
| 50s · consolidate | 43% | 10% | 8% | 9% | 30% | 70% |
| 60+ · preserve | 34% | 8% | 5% | 7% | 46% | 54% |
Illustrative allocations for discussion, not individual recommendations. Your risk tolerance, other savings, and retirement date should adjust these.
In your 30s and 40s: let growth lead
With decades ahead, your biggest risk is being too cautious and arriving short. Growth-tilted allocations lean toward the stock funds; a downturn at this stage simply means continuing to buy at lower prices for years before the money is needed.
In your 50s and 60s: protect what you've built
The math quietly flips. The gain from an extra few percent in stocks starts to matter less than the damage a bad year could do right before you retire — the problem advisors call sequence-of-returns risk. Raising the bond and money-market funds is how you defuse it without abandoning growth entirely.
Apply any of these mixes to your own balance and see how it projects:
The target-date shortcut — and its catch
Most plans default you into a target-date fund, which applies a glide path like the one above automatically. It is a reasonable default, but it moves on a fixed schedule regardless of conditions and rides every downturn fully. We weigh that trade-off in target-date funds: convenience vs. cost. To compare your current mix against a more deliberate one, use the 401(k) Calculator.
The part that actually matters: discipline
A sound allocation only helps if you hold it through the rough stretches and change it for the right reasons. That is the idea behind the 401(k) Edge strategy — a rules-based monthly update that works with any plan and any provider, so your 401(k) follows evidence instead of emotion. Most months, it says do nothing.
