Ritholtz Wealth Management sets asset allocation at age 60 by matching bonds and cash to near-term withdrawals, not by applying an age formula. Take a retiree planning to draw $60K a year. She needs $300K reserved for five years of withdrawals before anyone decides how much of the rest belongs in stocks. What changes at 60 is cash flow: soon no paycheck will cover the bad months. Ritholtz Wealth Management maps the withdrawal reserve, account locations and tax effects before suggesting a fund change. Age-based splits look tidy, but retirement spending rarely is.

Step 1: Put a monthly number on the paycheck your portfolio must replace
Start with the last 12 months of spending, then subtract income you expect to keep receiving. Social Security, a pension, rental income and part-time work reduce what the portfolio must supply. If the remaining gap is $60K a year, the portfolio paycheck is $5K a month.
Separate the first five years of this gap from later spending. Those early withdrawals may come due while stocks are down, and that is the worst time to be forced to sell a large stock position. Ritholtz Wealth Management asks clients to name the accounts that will fund those first checks before anyone picks an allocation percentage.
Gather the numbers before opening a brokerage screen. A spreadsheet is fine; an estimate based on memory usually understates travel, home repairs and health costs.
Shortcut: If portfolio withdrawals will pay spending for the next five years, reserve five annual withdrawals in cash and high-quality bonds before choosing the stock percentage for the rest.
- Spending record: total the last 12 months, including irregular bills.
- Dependable income: list the monthly amount and its start date.
- Portfolio gap: divide the annual shortfall by 12 for the monthly draw.
Step 2: Put a date beside each income change
Write down the last paycheck, pension start, Social Security claim date, Medicare enrollment at age 65 and the age when required minimum distributions begin. The IRS says RMDs generally start at age 73, or age 75 for people born in 1960 or later. Dates matter because a withdrawal that looks harmless in March can change taxable income after a pension begins or a paycheck ends. Ritholtz Wealth Management uses the calendar to stage trades rather than treating retirement as one event.
Step 3: How Ritholtz Wealth Management tests asset allocation at age 60
Five annual portfolio withdrawals belong in cash and high-quality bonds when those withdrawals will fund the first five years after work ends. Multiply the planned annual draw by five, compare that result with current bonds and cash, then set the stock share for money needed later. This is a spending shortcut, not a market call.
For a $60K annual draw, the arithmetic is plain: $60K a year × five years = $300K. If the retirement-income sleeve is $1.2M, $300K ÷ $1.2M = 25% in cash and bonds before any separate emergency reserve. A calculator on this site can run the same math with your spending number.
For illustration, Olga is hypothetical, age 64, a widowed retired software architect with a paid-off house and a three-fund portfolio she ran herself for 25 years. She has $2.3M invested 90% in stocks and 10% in bonds, and expects to draw $70K a year after work ends. Five years of draws equal $70K × five = $350K. Her existing bond balance is $2.3M × 10% = $230K, so $350K − $230K = $120K more belongs in the reserve.
Olga moves $60K from stocks in each of two tax years. That produces $230K + $60K + $60K = $350K reserved for the first five years. Before those sales, Ritholtz Wealth Management would check which account holds the stock, its cost basis and the gain each sale creates. Splitting the move into two sales does not always help. It can, however, give a retiree more control over taxable income in each year.
Treating a generic 80/20 allocation as a complete answer can leave a $60K-a-year retiree with only $240K in bonds, forcing a stock sale after four years if markets have been weak. The table shows why the allocation label matters less than the years of spending it actually covers. A large pension or very low portfolio draw can justify less than five years; a home purchase or uneven spending can require more.
Calculate the reserve before choosing a percentage
Olga's two-year move from stocks
| Allocation change | Stock value | Bond and cash value | Years at $60K |
|---|---|---|---|
| Before: 80/20 | $960K | $240K | four years |
| After: 60/40 | $720K | $480K | eight years |
| After: 50/50 | $600K | $600K | 10 years |
Step 4: How can a bond move raise Medicare costs?
Selling stock to build a bond reserve can affect a future Medicare Part B premium because realized gains can enter modified adjusted gross income. For 2026, Medicare uses a single filer’s $109,000 first IRMAA threshold, based on income from two years earlier. Taxable interest, dividends, realized capital gains, traditional IRA withdrawals and Roth conversions can count; qualified Roth IRA withdrawals generally do not.
Olga's regular modified adjusted gross income is $90K. If a $60K stock sale has a $15K gain, her income for that year is $90K + $15K = $105K. A sale in a given tax year sets her Part B premium two years later. So the $105K should be compared with the threshold in force then; the 2026 first IRMAA threshold for a single filer is $109,000. Selling both lots in one year would produce $90K + $30K = $120K, above that level. The sale amount and the gain are separate numbers.
The CMS income-related monthly adjustment amount looks back to the tax return from two years before the premium year. IRS Form 8949 records each sale of a capital asset, and the tax return carries the gain into income. A Roth conversion strategy or tax-efficient investing review can matter here, but the retirement reserve still comes first.
Investment values can fall, including money originally invested; a bond reserve reduces pressure to sell stocks soon, but it does not remove inflation, interest-rate or market risk. Ritholtz Wealth Management uses long-term research and diversification, not a forecast about next quarter’s market.
A gain, not the full sale, enters income
The two-year Medicare lookback
| Measure | 50/50 | 60/40 | 80/20 |
|---|---|---|---|
| Stock value | $600K | $720K | $960K |
| Bond and cash value | $600K | $480K | $240K |
| Years of withdrawals | 10 years | eight years | four years |
| Amount above $300K target | $300K | $180K | -$60K |
| Reserve action | No sale needed | No sale needed | Move $60K |
Step 5: Refill the reserve without waiting for a forecast
Move the required reserve before the last paycheck ends when practical, then refill it after strong market years or when other income cuts withdrawals. Do not wait for someone to announce that stocks have peaked. At age 60, the point is to know which account pays the next $5K a month, not to predict the next headline. A second-opinion plan review can test whether a 401(k) rollover to an IRA would make that withdrawal order easier or create new trade-offs.
Your questions about asset allocation at age 60, answered
How much of a $1.2M portfolio should be in bonds at age 60?
Start with spending, not age. A $60K annual portfolio withdrawal multiplied by five years calls for $300K in cash and high-quality bonds, or 25% of a $1.2M portfolio. A retiree who wants a larger reserve, expects uneven expenses or has little outside income may hold more.
Can my adult children follow the same allocation after I die?
Adult children should not copy the allocation automatically. A surviving spouse may need a different reserve because tax filing status, Medicare income thresholds and monthly spending can change. Give family members a current list of accounts, expected withdrawals and the purpose of each cash or bond holding.
When should I move stock proceeds into bonds before retirement?
Move enough before the last paycheck ends to cover the planned reserve, after checking gains and tax timing. Spreading sales across tax years can be useful when one large sale would create a larger gain or cross a Medicare income threshold. Do not base the timing on a market forecast.
Does selling stocks to buy bonds affect Medicare premiums?
It can. Medicare IRMAA uses modified adjusted gross income from two years earlier, and a realized capital gain from a stock sale can count in that income. For 2026, the first threshold is $109,000 for a single filer. The gain, not the total sale proceeds, is the relevant amount.
Can I keep five years of withdrawals in bonds and still own stocks?
Yes. The reserve covers near-term spending, while stocks can remain invested for later retirement years. In a $1.2M portfolio with a $60K annual draw, a $300K reserve leaves $900K available for stocks, additional bonds or both. The right mix depends on spending needs and other income.
Step 6: Give the surviving spouse a usable spending map from Ritholtz Wealth Management
A surviving spouse may have a new filing status, a different spending gap and different Medicare income thresholds, so recalculate the reserve after a death. Adult children need a short list showing which account holds the next several years of spending, who to contact and which sales create gains. “If my paychecks stop next year, which accounts would supply five years of withdrawals, and what taxable sale would that require?” Bring that question to Ritholtz Wealth Management and ask for annual withdrawals, realized gains and the surviving-spouse version of the plan.
Your stock percentage comes after you know which account pays next month’s check.
