In 2026, with retirements lasting 25–35 years and bonds yielding less than they once did, the math has shifted.\n\nHere's a 2026-aware framework, with three concrete templates by life stage.\n\n## What changed in 2026\n\n- **Life expectancy assumes longer retirement** — a 65-year-old today is reasonably planning for living to 90+, which means a 25–30 year retirement. Equity is necessary for so long a horizon.\n- **Bond yields have settled to 4.0–5.0%** — better than the 2020 floor, but still below historical 5–6%.\n- **Glide path research is mainstream** — Wade Pfau's work on the \"rising equity glide path\" through retirement suggests that LOWER equity allocation in early retirement, gradually rising again, can reduce sequence-of-returns risk.\n\n## Three popular rules — pros and cons\n\n### 100-minus-age (classic)\nAt age 30: 70% equity / 30% bonds. At age 60: 40% equity / 60% bonds.\n\nPro: simple. Con: too conservative for modern life expectancy. Most advisors now recommend 110- or 120-minus-age.\n\n### 110-minus-age (modern updated)\nAt age 30: 80% equity. At age 60: 50% equity.\n\nPro: accounts for longer retirement. Con: still mechanical.\n\n### Bogleheads three-fund (target-based)\n- 60% Total US Stock + 30% International Stock + 10% Bonds (aggressive, young)\n- 50% / 25% / 25% (moderate, middle-age)\n- 30% / 15% / 55% (conservative, near retirement)\n\nPro: captures asset diversification, not just stock-bond split. Con: requires more thought.\n\n## Practical templates by age\n\n### Age 25–35: aggressive accumulation\n\n```\n70–80% Equity (60% US / 20% International)\n0–10% Bonds (or none)\n5–10% Other (REITs, gold optional)\n```\n\nRationale: 30+ year horizon, time for compound growth and recovery from drawdowns. Bonds add little when you're earning new contributions to fund opportunistic buying during dips.\n\n### Age 35–50: balanced accumulation\n\n```\n65–70% Equity (50% US / 20% International)\n20–25% Bonds\n5–10% Other\n```\n\nRationale: peak earning years. Some bond allocation reduces volatility without significantly impacting expected return.\n\n### Age 50–65: pre-retirement\n\n```\n50–60% Equity (40% US / 15% International)\n30–40% Bonds (mix of intermediate Treasury, TIPS, short-term)\n5–10% Other (cash buffer if planning early retirement)\n```\n\nRationale: protect what's been built. Sequence-of-returns risk peaks in the 5–10 years before retirement.\n\n### Age 65–75: early retirement\n\n```\n40–55% Equity\n35–45% Bonds (laddered)\n5–15% Cash / Money market (1–3 year spending buffer)\n```\n\nRationale: drawdown phase begins. Cash buffer reduces forced selling during equity drawdowns.\n\n### Age 75+: late retirement\n\n```\n30–50% Equity\n40–55% Bonds\n5–15% Cash\n```\n\nEquity allocation depends on portfolio size relative to spending. If portfolio is multiples of annual spending, higher equity is fine.\n\n## Comparison: equity allocation by rule and age\n\n| Age | 100-minus-age | 110-minus-age | Modern target-date 2065 |\n| --- | --- | --- | --- |\n| 30 | 70% | 80% | 90% |\n| 40 | 60% | 70% | 85% |\n| 50 | 50% | 60% | 70% |\n| 60 | 40% | 50% | 60% |\n| 70 | 30% | 40% | 45% |\n\nMost modern target-date funds run higher equity than the \"100-minus-age\" rule.\n\n## The rising-equity glide path (advanced)\n\nWade Pfau's research suggests that during retirement, an *increasing* equity allocation can reduce failure rates. Logic: the worst sequence-of-returns risk is concentrated in the first 10 years; if you start retirement with lower equity and gradually rise (e.g., 40% → 60% over 20 years), you mitigate the early-drawdown risk while still capturing equity growth in later years.\n\nThis is contrary to the typical \"target-date glide path\" which decreases equity through retirement. Implementing it requires more active management.\n\n## What most people get wrong\n\n- **Default-allocating into employer's target-date fund without checking the glide path.** Some are too conservative for young investors.\n- **Treating \"international\" as 0%.** US-only is concentrated. 20% international is the safer middle ground.\n- **Holding more cash than needed.** A 6-month emergency fund is not part of asset allocation; it's separate. Don't double-count.\n- **Rebalancing to allocation but not updating the target as they age.** A 35-year-old with a 70/30 allocation set at age 28 hasn't aged their portfolio.\n\n## FAQ\n\n**Should I include my home equity in asset allocation?**\nGenerally no. Home equity is illiquid and serves a consumption purpose. Calculate allocation on liquid investable assets only.\n\n**What about pension or social security?**\nTreat expected pension/SS as a \"bond equivalent\" — it lets you hold higher equity in your liquid portfolio because you have predictable income elsewhere.\n\n**How often should I update my allocation?**\nEvery 5 years, or after major life events (marriage, kids, job change, inheritance, etc.). Annual fine-tuning is usually unnecessary.\n\n## Where to go next\n\nFor related guides see [Portfolio rebalancing guide for 2026](/blog/portfolio-rebalancing-guide-2026), [How to invest in stocks for beginners in 2026](/blog/how-to-invest-in-stocks-beginners-2026), and [Retirement bucket strategy for 2026](/blog/retirement-bucket-strategy-2026).","hue":274,"metaTitle":"Asset Allocation by Age 2026: Practical Glide Path","metaDescription":"Asset allocation by age in 2026 — the popular rules updated, a three-fund portfolio template, and a practical glide path from 25 to 65.","keywords":["asset allocation by age","100 minus age rule","bogleheads three fund portfolio","glide path retirement","target date fund allocation","equity allocation by age","portfolio by age 30","retirement asset allocation","60 40 portfolio","sequence of returns risk"],"tldr":["**The \"100-minus-age in equity\" rule is now considered too conservative** for most healthy investors with longer life expectancy — modern advice runs 110- or 120-minus-age.","**A three-fund portfolio (US + International + Bonds) at age-appropriate weights covers 90% of the value** of more complex allocations.","**Glide paths matter more in retirement years** — sequence-of-returns risk concentrated in years 60–70 means the late-50s drawdown is the riskiest single point.","**Skip:** target-date funds with overly high bond allocations at younger ages — many \"2065 Target Date\" funds are 90/10 equity/bonds, which may be too conservative for a 25-year-old."],"readTime":"4 min read","wordCount":833},"related":[{"slug":"glidepath-explained-2026","title":"Glidepaths: How a Portfolio Should Change With Age","excerpt":"The rule that you hold your age in bonds is memorable and arbitrary.
