The 4 Percent Rule and Retirement Withdrawals
Where the 4 percent rule came from
You’ve probably heard of the “4% rule.” It’s one of those things that gets repeated so often in retirement planning that it sounds like gospel. The idea is simple: if you withdraw 4% of your portfolio each year, adjusted for inflation, your money should last about 30 years.
That idea came from research in the 1990s when interest rates were high, inflation was steady, and markets were much more predictable than they are now. Back then, bonds were paying around 6%, stocks were averaging double-digit returns, and retirement was expected to last maybe two decades.
A lot has changed since then.
Why a historical guideline is not a guarantee
I sometimes joke that the 4% rule was basically designed to make big firms feel safe and a bunch of the heads of the largest brokerage firms whispered “Tell them to take 4%, and they’ll never run out of money.” And they were right—because 4% almost always worked. The accounts grew, and so did the firms’ fees.
That formula doesn’t fit everyone anymore.
Today, people are living longer, interest rates swing wildly, markets move faster, and inflation isn’t the tame little number it used to be. Sticking to a rigid percentage doesn’t make sense in a world that’s anything but rigid.
Taxes and fees reduce spendable income
I’ve seen clients who could easily take 6% or 7% and be fine. I’ve also seen others who should stick closer to 3%. The truth is, no rule of thumb can replace real planning.
The biggest problem with the 4% rule is that it assumes you’ll increase your withdrawals every single year for inflation. In reality, very few retirees actually do that. Think about the last few years—we just lived through some of the highest inflation in decades, and almost none of my clients increased their income in lockstep. People naturally adjust.
They spend a little less when prices rise, and they spend more when things feel stable. That flexibility is what makes real retirement plans work.
Here’s how I think about it: retirement isn’t about picking a withdrawal rate. It’s about building a system that keeps you comfortable and confident no matter what the market does.
Market timing affects early retirement years
Since World War II, the market has always recovered within five years. That’s why I like to keep five years of income out of the market—safe, protected, and ready when you need it. That buffer buys you time. It means that when the market dips, you’re not forced to sell investments at a loss just to pay the bills.
The rest of your portfolio can stay invested for growth—to outpace inflation, handle rising healthcare costs, or leave a legacy for your family.
When you structure your income this way, you don’t need a magic percentage. You just need a repeatable plan that adjusts as life changes.
Spending can change over time
That’s what a lot of the old retirement research missed. People aren’t spreadsheets. Life isn’t static. Your spending will ebb and flow. Some years you’ll travel more. Some years you’ll spend less. The key is designing a system that can flex with you.
And honestly, this is where good financial planning really shines. The numbers matter—but the emotions matter more. You want to know that no matter what happens in the market, you can still live your life. That you’ve got income stability, growth for the long term, and the flexibility to make decisions without fear.
The 4% rule was a great starting point thirty years ago. It gave people a sense of structure when there wasn’t much guidance. I believe now we can do better. We can personalize it, make it smarter, and design it around you—not an outdated formula.
Use the rule as a starting point for planning
Some years you’ll take more -maybe in your early retirement years when you want to travel and your health is good.. Some years you’ll take less. That’s how real life works.
The truth is, retirement income planning isn’t about math—it’s about confidence. You want a plan that feels good when things are good and still works when they’re not.
So no, the 4% rule isn’t a rule. It’s a reminder: discipline matters, flexibility matters more, and the best plan is the one that keeps working even when the old rules stop making sense.
