Why this question matters so much
How much of your savings sits in stocks versus bonds is the most important investment decision you make in retirement. Stocks give you the growth needed to outpace inflation over a 25- or 30-year retirement, but they can fall 30% or more in a bad year. Bonds and cash are steadier but can quietly lose ground to inflation. Get the balance wrong in either direction and you risk either running out of money or losing sleep, and possibly selling at the worst possible time. The good news is that you do not have to guess; large fund companies publish the exact stock-and-bond paths they use for millions of retirees.
The old rules of thumb, and why they shifted
For decades, the standard rule of thumb was '100 minus your age' in stocks. By that math a 70-year-old would hold 30% stocks and 70% bonds. The rule was born in an era, as Morningstar notes, when memories of the 1929 crash were fresh, lifespans were shorter, and bond yields were much higher, so a conservative tilt made sense. But as life expectancies rose and people began spending three decades in retirement, many advisors concluded the old rule left retirees too timid and exposed to inflation.
That is why a more aggressive version, '120 minus your age,' has become common. By that formula a 70-year-old holds 50% stocks rather than 30%. Notably, Vanguard founder John Bogle himself endorsed using 120 minus age, explaining that the older guideline was written for a time of much higher bond yields. These formulas are starting points, not gospel, but the shift from 100 to 120 captures a real change: people are living longer, so their money has to last longer and grow more.
What the pros actually do: Vanguard's glide path
Rather than rely on a slogan, look at how the largest fund companies actually invest retirees' money. A 'glide path' is the pre-set schedule by which a target-date fund gradually shifts from stocks to bonds as you age. According to Vanguard's published glide path, its Target Retirement funds start young investors at about 90% stocks, hold roughly 60% stocks five years before retirement, and arrive at 50% stocks at the typical retirement age of 65. That 50% landing point at 65 is meaningfully higher than the old '100 minus age' rule would suggest for that age.
After retirement, Vanguard continues trimming stocks gradually until reaching 30% equities about seven years past 65, roughly age 72, and then holds that 30%/70% mix steady through the rest of retirement. Morningstar's analysis of Vanguard's Target Retirement 2025 fund confirms these figures and notes the 50% stock weight at retirement runs about 6 percentage points higher than the average competing fund, a deliberate choice to reduce the risk that retirees outlive their savings.
Translating that to ages 60, 70, and 80
Putting the research together gives a practical range. Around age 60, when you are five or so years from a traditional retirement, the Vanguard glide path points to roughly 55% to 60% in stocks. At age 70, you are in the transition zone, with a sensible range of about 35% to 50% stocks depending on whether you favor the cautious '100 minus age' end or the growth-oriented '120 minus age' end. By age 80, you are at or below the long-term landing point, generally around 30% stocks, the level Vanguard holds steady for the rest of retirement.
These are ranges, not prescriptions. Your own number depends on factors a formula cannot see: how much guaranteed income you have from Social Security and pensions, how large your nest egg is relative to your spending, your health and family longevity, and crucially, how well you sleep during a market drop.

The bucket approach: structure that calms nerves
If percentages feel too abstract, Morningstar's Christine Benz popularized a more intuitive method called the bucket approach. Instead of thinking in stock-and-bond percentages, you organize your money by when you will spend it. As Benz describes it, Bucket 1 holds one to two years of anticipated portfolio withdrawals in cash, Bucket 2 holds roughly five to eight years of spending in high-quality bonds, and Bucket 3 holds the remainder in stocks for long-term growth, geared toward year 11 and beyond of retirement.
The genius of the bucket setup is psychological as much as financial. When stocks tumble, you do not have to sell them at a loss to pay the bills, because you have years of spending already parked in cash and bonds that are not falling. You simply draw from those buckets and give your stocks time to recover, refilling the cash bucket from stocks during good years. As Benz puts it, the retiree should always be able to draw living expenses from an asset class that is in the black. For many people over 70, that peace of mind is the difference between staying invested and panicking.
Common mistakes to avoid
Two errors show up again and again. The first is being far too conservative, holding only 10% or 20% in stocks at 65 out of fear, and then watching inflation erode purchasing power over a 25-year retirement. The second is the opposite: keeping 70% or 80% in stocks into your 70s and 80s, then being forced to sell deep in a bear market to cover expenses, a mistake that can permanently shrink a nest egg. The glide-path ranges above and the bucket approach are both designed to steer you between these two ditches.
A third, quieter mistake is letting your allocation drift. After a strong stock run, a portfolio you set at 50% stocks can creep to 65% without you noticing, leaving you far more exposed than you intended right before a downturn. Rebalancing back to your target once a year, or whenever your mix drifts more than about five points, keeps your actual risk in line with the plan you chose.
The bottom line
There is no magic stock percentage stamped on your birthday, but the professional consensus is clear enough to act on. Vanguard's real-world glide path lands near 50% stocks at 65 and roughly 30% by the early 70s, and Bogle's '120 minus age' update reflects the reality that retirements now last decades. Whether you express your plan as a percentage or as Christine Benz's spending buckets, the goal is the same: enough stocks to keep growing, enough safety to sleep at night, and enough discipline to leave it alone when markets get loud.
