Key Takeaways
- • SmartAsset's guide frames 401(k) allocation as an age-driven glide path, with stock exposure typically reduced as retirement approaches, and cites a common rule of thumb of subtracting age from 110 or 120 to estimate the equity share.
- • Suggested bond allocations run roughly 10-20% in the 20s and 30s, rising to 30-40% in the 40s and 50s and to 50% or more in the 60s and beyond.
- • Suggested alternative allocations (REITs, commodity funds) are 5-10% for younger investors and 10-15% for those in midlife, though alternatives are not available in every 401(k) plan.
- • Per Vanguard's "How America Saves 2026" report, 96% of Vanguard defined contribution plans offered target-date funds in 2025.
- • The article stresses that age-based figures are averages and general guidelines, and recommends periodic review, rebalancing, and consultation with a financial advisor.
Summary
SmartAsset's guide on 401(k) asset allocation by age argues that the appropriate mix of stocks, bonds and alternatives shifts as an investor's time horizon and risk tolerance change. Younger investors, with decades until retirement, can typically hold more equities to capture long-term growth, while those nearing retirement generally shift toward bonds and cash to preserve savings. The article describes a common rule of thumb of subtracting age from 110 or 120 to estimate the portion of a portfolio that should be in stocks, and it notes that these figures are starting points rather than prescriptions.
The article references average 401(k) stock allocations by age drawn from Vanguard's "How America Saves" report, which it presents as evidence that investors gradually become more conservative over time. Bond guidance is laid out in ranges: about 10-20% in the 20s and 30s, 30-40% in the 40s and 50s, and 50% or more by the 60s and beyond. The article also addresses alternatives, noting that REITs and commodity funds can help hedge inflation and volatility, with suggested allocations of 5-10% for younger investors and 10-15% for those in midlife. It cautions that alternatives are not always available within a given plan.
On implementation, the article uses a worked example of a $200,000 401(k) with a 70% stock and 30% bond target. A 20% rise in stock values would lift the equity weight to approximately 73.7%, and restoring the target would require moving $8,400 from stocks to bonds, leaving $159,600 in stocks and $68,400 in bonds, assuming no contributions, withdrawals or fees. Alternatives to selling include directing new contributions to underweighted holdings or using automatic rebalancing. The article also points to target-date funds, which adjust allocations as a retirement year approaches; citing Vanguard's 2026 report, it states that 96% of Vanguard defined contribution plans offered such funds in 2025.
The article concludes that allocations should be reviewed once or twice a year or after significant life changes, and that the right mix depends on time horizon, risk tolerance and broader financial goals. It includes a quote from CFP Brandon Renfro emphasizing that guidelines should not be followed blindly. The piece is consumer-oriented retirement education and includes promotion of SmartAsset's advisor-matching service and retirement calculator.
