My Issues With The 3-6 Month Emergency Fund Heuristic
When a client asked me recently, “How do we know a 3-6 month emergency fund is enough?” I gave her the only honest answer I have:
“We don’t.”
The 3-6 month rule wasn’t handed down on stone tablets. Financial advisors settled on it because it roughly matches the average duration of a job loss for a neurotypical person. It’s a population-level heuristic—a “good enough” guess for the average person.
Stacks of coins with seedlings on top getting larger. With the words “The ‘3-6' Month Rule’ is Failing ADHD Women. Why populations-level heuristics don’t account for the ‘ADHD Tax’ and how to build a safety net that actually fits your brain.
But as women with ADHD, we aren’t “average.” Our lives don’t always follow a linear path, and our expenses certainly don’t.
The ADHD Tax is Real
Why do I believe we need more than the standard advice? Because we deal with variables that the “3-6 month rule” ignores:
We create our own “mini-emergencies”: Late fees, missed renewals, forgotten subscriptions, and last-minute “I need this now” expenses.
The Impulse Factor: Our brains crave dopamine, which often leads to impulsive spending that can deplete a standard savings account faster than we can track.
The Safety Gap: Research shows that people with ADHD are 1.8–2.1 times more likely to experience injuries or accidents. Our physical world is often as chaotic as our mental one.
From Chaos to Control: The 5-8 Month Goal
For my clients, I recommend shifting the goalposts. Instead of 3-6 months, aim for 5-8 months. I know—that sounds heavy. If you’re feeling chest tightness just reading that, breathe. We aren’t doing this overnight. We are building a buffer that accounts for your unique brain, not a textbook definition of “stable.”
The Plan:
Start Small: $5 here, and there adds up faster than you realize.
Milestones: Aim for $100. Then $500. Then $1,000.
Celebrate: Every time you hit a milestone, acknowledge it. Your brain needs that dopamine hit to keep going.
Take it one step at a time. Your future self will thank you for the extra breathing room.
