A 401(k) is an accumulation vehicle. Everything about the way it is designed the annual contribution limits, the investment options, the employer match, the tax deferral is built around the question of how to grow a balance over time. The plan sponsors who designed it were thinking about how to help workers save. They were not thinking about how those workers would eventually live off what they saved.
Retirees who want to generate income from a 401(k) generally choose from three approaches, each with different characteristics for control, longevity risk, and predictability. Systematic withdrawals involve the retiree taking periodic payments monthly or annually from the account. The account remains invested, and the retiree adjusts the amount as needed. This is the most flexible option and preserves the ability to change course, reduce withdrawals during a market decline, or leave remaining assets to heirs. The tradeoff: the retiree absorbs all longevity risk and market risk. If the market performs poorly early in retirement and the withdrawal rate is too high, the account can be depleted before the retiree dies. Annuitization involves using a portion of the 401(k) to purchase an immediate annuity an insurance contract that provides a guaranteed payment for life. This transfers longevity risk entirely to the insurance company. The tradeoff: the payment is generally fixed, inflation erodes it over time, and the premium is surrendered permanently. Access to principal disappears. IRA rollover is the most common choice at retirement. Moving the 401(k) to an IRA expands investment options and in many cases reduces fees. The IRA operates under the same systematic withdrawal logic the retiree must build a distribution strategy from the ground up. The rollover itself does not create an income plan; it creates a new account in which an income plan must be built. Distribution Liquidity Lifetime Primary Primary Risk** Approach Guarantee Benefit** Systematic High No Full control Sequence risk; Withdrawals and legacy possible depletion potential Annuitization Low Yes Income Loss of principal; regardless of fixed, not lifespan inflation-adjusted IRA Rollover High No Broader No plan retiree options; better must build one fees Full Cash-Out Maximum No Immediate Full tax hit; capital access destroys tax deferral
Target-date funds mutual funds that automatically shift from more aggressive to more conservative investments as a target year approaches have become the default investment in most 401(k) plans. They serve accumulation well. Their suitability for a retiree drawing income is a different question. A target-date fund uses a glide path a programmed reduction in equity exposure as the participant approaches the fund's target year. There are two types. A 'to retirement' fund reaches its most conservative allocation at the target date and stops shifting. A 'through retirement' fund continues de-risking for 10 to 20 years beyond the target date, acknowledging that a 65-year-old may have a 30-year income horizon and still needs equity exposure to combat inflation. The deeper problem is that target-date funds are designed without visibility into the participant's total financial picture. A retiree with a $5,000 monthly pension and a $200,000 401(k) has a fundamentally different risk profile than a retiree with no pension and $1,500,000 in a 401(k). The pension is essentially a fixed-income asset the equivalent of a large bond portfolio. For the first retiree, investing the 401(k) conservatively in a target-date fund doubles down on fixed income and sacrifices growth potential. For the second retiree, a target-date fund's conservative allocation may be entirely appropriate. Target-date funds are not wrong. They are indifferent to individual circumstances, which is a different problem. **A target-date fund knows your birth year. It doesn't know whether you have a pension, how much Social Security you collect, whether you have a spouse, or how long your family lives. The glide path is calibrated to an average retiree who doesn't exist.***
Variable annuities with Guaranteed Lifetime Withdrawal Benefit riders represent a product category that attempts to occupy the space between systematic withdrawals and full annuitization. Under a GLWB, the retiree invests in a variable annuity and is permitted to withdraw a set percentage of a guaranteed benefit base each year typically 4 to 5 percent. If the account value eventually falls to zero due to withdrawals and market performance, the insurance company continues to pay the guaranteed withdrawal amount for the rest of the retiree's life. GLWBs offer real value for retirees who want market participation and a longevity floor. They come with costs annual rider fees on top of the underlying variable annuity expense ratios that can meaningfully reduce net returns. Evaluating them requires understanding not just the guaranteed withdrawal rate but the total annual cost of the contract, the surrender charge schedule, and the terms under which the benefit base grows.
The 4 percent rule the guideline suggesting that a retiree can withdraw 4 percent of their portfolio in the first year of retirement, adjust for inflation annually, and have a high probability of not running out of money over 30 years originated from research by William Bengen published in 1994. It was based on historical U.S. market returns and a specific asset allocation. Subsequent research, including updated analysis from Morningstar, has suggested that current conditions lower projected returns for fixed income, higher starting valuations for equities, and higher inflation may make the sustainable withdrawal rate closer to 3.3 to 3.7 percent for a 30-year retirement. None of these are fixed rules. They are probabilistic estimates that depend heavily on sequence of returns in the first decade of retirement. A retiree with other guaranteed income Social Security, a pension, or an annuity can afford to take more risk with the portfolio and withdraw at a higher rate from the invested portion, because the guaranteed income covers baseline expenses. A retiree with no guaranteed income sources and a single account is in a more vulnerable position.
