Is a plan in your head good enough?
Most people have some kind of plan for their money. Far fewer have it written down. In Schwab’s 2025 Modern Wealth Survey, only 31% of Americans said they had defined their financial goals and documented them in a formal plan.
Having a plan is good. Having a written plan is even better, and for more reasons than you might think.
Writing it down forces clarity
The first benefit shows up right away. Most people who sit down in my office for the first time don’t have objective, measurable goals. They have a feeling (“we’d like to retire comfortably”), which is a fine place to start, but it’s not a plan. Putting a real plan on paper forces everyone to define the goals, clarify them, and then put numbers on them.
It also gives you a scorecard that’s actually yours. You get to measure your progress against your own plan, not against your buddy from the club. Goals are personal, and so is progress toward them.
A written plan is your guardrail against panic
This is the big one. Greed and fear are the most powerful emotions in investing, and both can do serious damage to a shaky plan when something out of the ordinary happens. A written plan, agreed to by everyone involved, is your survival guide, drawn up in calm waters by rational minds.
I can’t tell you how many panicked calls I’ve gotten during a market meltdown or an unexpected family expense, only to hear a sigh of relief when I remind the person on the other end that we have a plan, and it was written for exactly this kind of moment.
What does panic actually cost?
Morningstar has a way of putting a number on it. Every year, its “Mind the Gap” study compares what funds returned with what the people who owned those funds actually earned. In the 2026 edition, covering the 10 years through 2025, the average dollar invested in U.S. mutual funds and ETFs earned 8.7% a year, while the funds themselves returned 9.9%.
That’s a gap of about 1.2 percentage points a year, roughly 12% of the funds’ total return. Same funds, same investments, different results. Morningstar ties the gap to when investors bought and sold, and the usual pattern is selling when things are down and buying when things are up (yikes). That’s the opposite of what we’re trying to do.
A written plan won’t make anyone immune to that. But at the very least, it makes you stop and ask whether you’re trying to time the market, instead of focusing on time IN the market.
The bonus: getting couples on the same page
We joke that financial advisors are also part-time marriage counselors. Couples can be in lockstep on almost everything that affects their family, but very few ever sit down and talk through their visions and values for their financial future.
A written plan forces that conversation, usually with me in the middle as a friendly moderator. In my experience, that conversation is often worth as much as the plan itself.
Where that leaves you
Whether your plan lives in your head, on a napkin, or in a binder, the question is the same: would it hold up the next time markets get ugly or life throws you a curveball? If you’re not sure, that’s where we can actually help.
You know where to find me.
