Financial planning requires quite a bit of thinking about money. (No shocker there.)

We think about investment returns and savings rates. Tax strategies and retirement projections. How much cash to keep on hand, and whether the plan can withstand whatever the market—or life—throws at it.

All this strategizing and projecting is aimed at one goal: preparing for uncertainty in your financial life. By doing so, you don’t have to scramble when unexpected things inevitably happen. You also don’t have to question every financial decision you make. (“Can we afford this? How will this impact our other goals?”) You have a plan in place, and that plan gives you direction.

That’s the irony: Though it requires extensive forethought, if a financial plan does its job well, it should eventually allow you to spend less time thinking about money.

And that peace of mind—the freedom to stop questioning every financial decision and life event—is a return you’ll never see on a performance report, but it’s an important one.

the Hidden Cost of Financial Stress

A recent study published in Innovation in Aging offers an interesting perspective on why this matters. Researchers examined financial adversity throughout adulthood and found that persistent financial hardship was associated with poorer verbal memory and processing speed by midlife.[1]

This research isn’t proof that financial hardship caused cognitive decline (there are many factors that influence cognitive health). And this study examined persistent low income and financial hardship—not whether well-off individuals had sufficiently optimized financial plans.

But the research reveals an important truth: Financial stress can carry costs that don’t show up on a balance sheet.

One potential explanation the researchers discuss is cognitive burden. A person only has so much mental bandwidth, and when financial worries continually occupy some of it, there’s less “room” for everything else that requires their attention. [2]

That doesn’t mean reaching a certain net worth eliminates financial stress or that a bigger portfolio guarantees a healthier brain. But it does suggest that reducing uncertainty (and consequently, worry) around finances can impact not only your balance sheet, but your mental well-being.

Creating Financial Margin

Having a great financial plan won’t eliminate all of life’s financial stressors. Markets will still fall. Careers will change. Cars will break down. Kids will need braces.

But planning helps you structure your finances so this kind of ordinary unpredictability doesn’t become extraordinary disruption. Building emergency funds, obtaining appropriate insurance coverage, living below your means, saving consistently, and maintaining a diversified portfolio—individually, none of these things is particularly groundbreaking. But together, they create margin.

With this kind of margin, a bad year in the stock market doesn’t have to derail your retirement plans. Losing a job doesn’t mean missing a mortgage payment. Replacing the plumbing in your home will be annoying—but not financially disastrous.

Creating intentional financial margin can also give you more freedom when you’re considering things like a career change, retiring earlier, helping family, or simply deciding what comes next.

We talked last month about building systems that make good financial habits easier to maintain. This is part of the reason why. Automated saving, a diversified portfolio, and a long-term investment strategy help create financial margin. But these systems also create mental margin. When the right decisions are built into the plan, you don’t have to keep making them over and over again—and that reduces your cognitive load.

That’s the beauty of a strong financial plan—it organizes your financial life so that money isn’t constantly demanding a decision from you. You make thoughtful choices upfront, put the right systems in place, and revisit them when circumstances warrant it. Apart from that, the plan should do most of the work in the background.

When Money Can Work in the Background

There will always be plenty of things for you to think about—your family, your health, what you want the next decade to look like. Whether mid-August is objectively too early for school to start…

A good financial plan gives you more room to think about those things. That means more room not just on your balance sheet, but in your brain, and in your life.
