For decades, retirees have been told to follow the “4% rule.”
The idea is simple: withdraw 4% of your portfolio in your first year of retirement, then increase that dollar amount each year for inflation. If you retire with $1 million, that means withdrawing $40,000 in year one, then adjusting that amount upward over time.
As a starting point, this can be useful.
But retirement is too important to run on a rule of thumb.
The limitation of the 4% rule is not that 4% is always too high or always too low. The limitation is that the rule is rigid. It does not respond to markets, taxes, life expectancy, spending needs, or personal goals.
Consider the real-dollar impact.
A retiree starts with $1 million and withdraws $40,000. But if the market drops early in retirement and the portfolio falls to $720,000, the withdrawal may still continue, and after inflation adjustments, it may now be closer to $45,000.
That is no longer a 4% withdrawal.
It is 6.25%.
That matters because the retiree may be selling more of a smaller portfolio at exactly the wrong time. This is one of the major risks in retirement income planning: poor returns early in retirement can have an outsized impact when withdrawals are happening at the same time.
But the opposite can also be true.
If the portfolio grows from $1 million to $1.4 million, a strict 4% rule may keep the retiree spending roughly the same inflation-adjusted amount, even though the portfolio may be able to support more. In that case, the risk is not running out of money. The risk is underspending during the years when the retiree may be healthiest and most able to enjoy retirement.
That is why a better retirement income strategy should include guardrails.
Instead of blindly increasing spending every year, a dynamic strategy adjusts as circumstances change. If markets are weak and the withdrawal rate gets too high, the plan may call for pausing inflation increases or trimming discretionary spending. If markets are strong and the withdrawal rate falls too low, the retiree may be able to increase spending with more confidence.
The key is to separate essential expenses from discretionary expenses.
Essential expenses, like housing, groceries, utilities, insurance, and healthcare, should ideally be covered by stable income sources like Social Security, pensions, or other dependable income. Discretionary expenses — travel, gifts, hobbies, upgrades, and family support — can often be managed more flexibly.
That flexibility is what turns a withdrawal rate into a retirement income plan.
The 4% rule can answer the first question: “Where do I start?”
But it does not answer the more important question: “When should I adjust?”
At Hanover Advisors, we help clients move beyond rules of thumb and build retirement income strategies around their actual lives: their income sources, tax picture, spending needs, risk tolerance, family goals, and legacy priorities.
Because in retirement, the goal is not simply to avoid running out of money.
The goal is to use your money wisely, confidently, and intentionally.
