Here’s the rule of thumb most people get told: subtract your age from 110 (or 120, depending on who you ask), and that’s the percentage you should hold in stocks. The rest goes in bonds. At 60 years old, that formula suggests somewhere between 50% and 60% stocks — and 40% to 50% bonds.
The problem? That formula was designed for people who retired at 65 and died at 72. The average 60-year-old today has a realistic shot at a 25-to-30-year retirement. A portfolio that’s 50% bonds at 60 is not built for 30 years of drawdown. It’s built for 10.
This is one of those cases where the conventional wisdom is outdated by a full generation, and following it uncritically will quietly damage your long-term purchasing power.
What Bonds Actually Do in a Portfolio
Before talking percentages, it’s worth being specific about what bonds are for. They don’t make you rich. They dampen volatility. When the stock market drops 30%, a bond allocation gives you something that holds its value — and ideally something you can sell to cover living expenses without being forced to sell stocks at the worst possible moment.
That last part is crucial. The primary danger bonds protect against isn’t market crashes in general. It’s being forced to sell stocks during a crash to pay your bills. If you have 2-3 years of expenses in bonds or cash, you can wait out a bear market without locking in losses. That’s the actual job.
Bonds also serve as ballast psychologically. A portfolio that drops 40% is harder to hold than one that drops 25%. People make their worst investment decisions in a panic, and a reasonable bond allocation reduces the emotional volatility that triggers those decisions. I watched this happen to colleagues during the 2008–2009 downturn — people who sold everything in October 2008 and missed the recovery. Their problem wasn’t their stock-to-bond ratio. It was that they held more volatility than their nervous systems could handle. Knowing your real risk tolerance matters as much as the math.
At Age 55: You Still Have Time, Use It
At 55, assuming a retirement target around 62-65, you have 7-10 years of continued contributions and compounding ahead of you. That runway changes the math significantly.
A reasonable target at 55: 65% stocks / 35% bonds.
You don’t need to be more conservative than this unless you have specific reasons — health concerns, a high-cost-of-living retirement destination, or an unusually short investment timeline. The sequence of returns risk (the danger of a bad market in the first years of retirement) isn’t fully activated yet. You’re still accumulating, not withdrawing.
At 55, the bond allocation is mostly about starting to build the buffer. You want to be accumulating bonds now so that when you retire in 7-10 years, you already have a cushion — you’re not scrambling to shift allocations in the middle of a bad market year right before you need the money.
One allocation mistake I see from this age group: going too conservative too early because the market just had a rough year. Don’t let recent volatility pull you toward bonds faster than your timeline justifies. Annual rebalancing keeps your allocation on track without requiring you to react emotionally to short-term market moves.
At Age 60: Sequence of Returns Risk Is Now Real
At 60, you’re typically 2-5 years from retirement. This is the highest-risk window for sequence of returns damage — a serious market downturn right before or right after you start withdrawing can permanently impair a portfolio in ways that later recoveries can’t fully fix.
I wrote about this connection in detail elsewhere, but the short version: a bad market in the first three years of retirement does more damage than a bad market at 75, because early in retirement you’re selling shares to live on before the recovery happens. Every share you sell during a crash is a share that won’t benefit from the rebound.
The bond allocation at 60 is your primary protection against this. A reasonable target: 55-60% stocks / 40-45% bonds.
My honest recommendation: be closer to 60/40 at age 60 than to 70/30. If you’re within three years of retirement, you shouldn’t be carrying a lot of sequence-of-returns risk in your allocation. A strong bull run in the three years before retirement is a nice bonus. A crash in those three years with 70% in stocks is a genuine problem.
At 60, also start thinking about the "bucket strategy": keep 2-3 years of living expenses in very stable assets (short-term bonds, money market, high-yield savings), a middle bucket of intermediate bonds covering years 3-7, and the long-term bucket in diversified stocks. This isn’t just psychological — it gives you a real spending plan that doesn’t force stock sales during bear markets.
At Age 65: Don’t Abandon Growth Assets
This is where the conventional wisdom does the most damage. A lot of people hit 65 and dramatically shift toward bonds because that’s what "retirement" is supposed to look like. They go from 60% stocks to 35% stocks in the span of a year or two, and they lock in a portfolio that can’t keep up with 25 years of inflation.
Here’s the math that makes me uncomfortable with that move: at 3% annual inflation, $60,000 in annual expenses today becomes roughly $125,000 in 25 years. A portfolio that’s 60% bonds and earning 3-4% annually won’t grow fast enough to maintain that purchasing power. You’ll run out of money not because the market crashed, but because you got too cautious too early.
A reasonable target at 65: 50-55% stocks / 45-50% bonds.
This is more conservative than at 60, but not dramatically so. The stock component is still above half because you need that growth engine running for the next 20-25 years. The bond component provides income stability and a cushion for the early withdrawal years.
The minimum I’d generally go below: 40% stocks at any point in a typical retirement, unless you have a pension or other guaranteed income source that covers your basic expenses without touching the portfolio. If Social Security plus a pension fully covers your monthly needs, your portfolio is essentially "extra" money — and extra money can carry more risk.
The Income Source Variable That Changes Everything
The right bond allocation isn’t actually determined by age alone. It’s determined by how dependent you are on your portfolio for income.
If you have a military pension, a teacher’s pension, a union pension, or very strong Social Security income that covers 80-100% of your monthly expenses — your portfolio can run more aggressively than the standard age-based frameworks suggest. You’re not depending on it for survival. A bad year doesn’t mean cutting expenses. In that case, 65% stocks at 65 or even 70% stocks at 67 might be entirely appropriate.
If your portfolio IS your primary income source — you’re planning to withdraw 4% per year to live on — the allocation should be more conservative in the early years because the sequence of returns risk is fully activated. Every monthly withdrawal is a share sold. You want more stability, not less, in years one through five.
This income-source variable is why generic age-based rules fail. Two people, both 62, with identical portfolio balances, might have completely different appropriate allocations based on what else is coming in every month.
Bond Type Matters, Not Just Bond Percentage
Not all bonds behave the same way. This matters especially when interest rates are moving.
Short-term bonds (1-3 year maturity): Low interest rate risk, modest yield. Good for the near-term spending bucket — money you’ll need in the next 2-3 years.
Intermediate-term bonds (5-10 year maturity): Better yield, more price fluctuation when rates rise. Appropriate for the middle bucket.
TIPS (Treasury Inflation-Protected Securities): Their principal adjusts with inflation. Particularly relevant for retirees worried about long-term purchasing power. Modest yields, but the inflation protection has real value over a 20-year retirement.
Long-term bonds (20-30 year): High yield, very high interest rate sensitivity. These can drop significantly when rates rise — similar behavior to stocks in some rate environments. Most pre-retirees should be cautious about heavy long-term bond exposure; it doesn’t provide the stability you think you’re buying.
A simple bond fund like Vanguard’s Total Bond Market Index (BND) or iShares Core U.S. Aggregate Bond ETF (AGG) provides diversified exposure across short, intermediate, and some long-term bonds in one holding. For most people this is entirely sufficient — you don’t need to build a bond ladder from scratch.
Where to Hold Bonds: Asset Location Matters
Once you’ve decided how much to hold in bonds, the next question is where to hold them. The answer: generally in your traditional (pre-tax) 401k or IRA, not in your Roth.
The reason: bond interest is taxed as ordinary income regardless of which account it’s in. So the tax treatment doesn’t change based on the account. But stocks held in a Roth grow tax-free — including all that future appreciation. Your highest-growth assets belong in Roth where the gains are never taxed. The specific index funds you hold matter less than which account holds them — asset location is an underappreciated lever.
Practical result: if you have both a traditional 401k and a Roth IRA, and you’re targeting a 60/40 allocation overall, lean toward holding bonds in the traditional account and stocks in the Roth. You’re essentially letting the most tax-efficient account hold the most tax-advantaged assets.
The Allocation Table That’s Actually Useful
This won’t be right for everyone — income sources, risk tolerance, health, and spending needs all modify these starting points. But as a baseline to start from:
- Age 55: 65% stocks / 35% bonds (accumulation phase, 7-10 years to retirement)
- Age 60: 55-60% stocks / 40-45% bonds (pre-retirement, sequence risk window)
- Age 65: 50-55% stocks / 45-50% bonds (early retirement, inflation still a 25-year concern)
- Age 70+: 45-55% stocks / 45-55% bonds (depending on income sources and health)
- Never below: 40% stocks if you expect to need portfolio growth for 15+ more years
My career in weather taught me one principle that applies perfectly here: the further out you’re forecasting, the more uncertainty you need to account for — and uncertainty in a long retirement is managed by keeping enough growth assets to outpace inflation, not by eliminating them. Reducing stocks at 60 because the market feels scary is like closing the road before the storm has even formed. You might be right. But the cost of being wrong is high.
Books That Get This Right
Wade Pfau’s research on sequence-of-returns risk and retirement asset allocation is the most rigorous work on this subject I’ve encountered. His Retirement Planning Guidebook covers the full framework — glide paths, bond allocation, withdrawal strategies — with actual math rather than rules of thumb. William Bernstein’s The Four Pillars of Investing remains one of the best explanations of why and how to hold a diversified stock-and-bond portfolio for a long time horizon — highly recommended if you want to understand the underlying logic rather than just follow a formula. And if you want the practical implementation side without the academic depth, The Simple Path to Wealth walks through stock-to-bond allocation in straightforward terms that anyone can apply.
Take Action: Check Your Current Allocation
Log into your 401k or IRA today and look at your current stock-to-bond split. Most plans display this on the home screen or under "portfolio" or "holdings." Compare it to the baseline ranges above for your age. If you’re significantly outside those ranges — more than 10 percentage points off in either direction — it’s worth reviewing whether that reflects a deliberate decision or just accumulated drift from an old allocation you set and forgot.
Fidelity’s NetBenefits platform and Vanguard’s account dashboard both show your current allocation clearly and let you model changes before implementing them. If you’re within 5 years of retirement and unsure whether your allocation is appropriate for your specific income situation, a one-time consultation with a fee-only financial planner (look for CFP credentials at NAPFA.org) is worth far more than the cost.
