Forget the Emergency Fund. Build a Buffer.
Why protecting your time matters more than preparing for disasters
In last week’s newsletter, I explored a simple four-part framework for placing your money: Priorities, Passions, Play, and Problems.
The goal wasn’t optimization or perfection.
It was alignment.
A way to fund your life without spreadsheets, shame, or guilt.
But there’s a catch.
Not all months are the same.
Some months flow beautifully.
Other months bring new tires, dental bills, urgent home repairs, or the sudden realization that every appliance in your house was apparently manufactured in the same week, swore a blood oath, and has decided to give up at the same time (we’ve had two different stoves over the years both choose to die exactly one week before Thanksgiving, as if they’d been waiting all year for maximum dramatic effect).
And when those larger expenses show up, they can feel like they break the system.
This is often the moment when people decide that any financial system they’ve tried “doesn’t work,” and they quietly give up.
Not because the system is flawed.
But because it wasn’t protected.
Why Systems “Fail”
Imagine getting in your car every day and driving just a little too close to the vehicle in front of you.
Every time they tap the brakes, you slam into them.
After the third or fourth rear-ending, you start to think maybe you’re the problem.
You’re not. You just need more space.
This isn’t a critique of your reaction time or your reflexes.
You’re doing the best you can with the space you’ve been given.
But eventually, it feels like you’re constantly in accidents.
And the problem isn’t driving.
The problem is that you don’t have a buffer.
When we run our finances without a buffer, every unexpected expense feels like a collision.
And if you’re constantly colliding with life, it’s hard to believe you’re getting anywhere at all.
What a Buffer Actually Does
When you’re driving, the space you leave between cars isn’t measured in feet.
It’s measured in time.
The faster you’re going, the more space you need.
Money works the same way.
There isn’t one correct buffer size for everyone, because not everyone is moving at the same financial speed.
The more you spend each month, the larger your buffer needs to be.
That’s why the common advice is three to six months of expenses.
But inside the Priorities, Passions, Play, and Problems framework, we can be more precise.
Your buffer should be built around your Priorities.
Your non-negotiables.
The costs of keeping your life intact.
A Simple Way to Build the Buffer
Let’s say your monthly priorities total $4,000.
Six months of that would be $24,000.
That number can feel heavy at first.
That’s normal.
You don’t need to get there all at once.
One steady approach is this:
Take your monthly priorities number and divide it by ten.
In this example, $4,000 divided by ten is $400 a month.
By doing this, you’re rebuilding roughly one month of priorities per year.
It’s slow.
It’s boring.
And it works.
No one will write a viral post about you saving $400 a month.
There will be no ticker-tape parade.
But six years from now, you’ll have a fully funded buffer, and you won’t remember how you got there.
“But What If That Takes Too Long?”
This is a fair concern.
If you’re starting from zero, fully funding a buffer this way could take several years. And yes, life can interrupt you before that happens.
So here’s the nuance:
If you can fund your buffer faster, do it.
Getting close to a fully funded buffer sooner rather than later creates real security. It’s often worth temporarily diverting extra cash, bonuses, refunds, or side income to get there.
Once you’re close, the system takes over.
Since we’ve been automatically sending ten percent of our priorities into the buffer each month, we’ve never really had to think about it again.
The buffer absorbs the dynamic parts of life without stress or drama.
When we need it, we use it.
Then it replenishes automatically, because the system is already in place.
Life doesn’t feel fragile.
It feels navigable.
Our buffer is fully funded, but we still send about ten percent of our priorities expenses into it each month so it stays proportional as our life changes.
As our priorities shift over time, the buffer quietly adjusts with them.
What the Buffer Is Not
This part matters.
A buffer is not a bonus spending category.
It’s not there to fund Play.
It’s not there to stretch your lifestyle.
It’s not there so a want can masquerade as a need.
A summer camp you know about months in advance isn’t a buffer expense.
That belongs in planning, not protection.
A vacation you want to take isn’t a buffer expense.
That’s Play.
Using the buffer for those things doesn’t make life safer.
It just quietly expands your expenses and weakens the system.
This is where your earlier work on Enough matters.
When you define a container for your life, you establish what fits inside it.
The buffer exists to protect that container, not to expand it.
The buffer absorbs collisions.
The container defines the boundaries.
You need both.
If you haven’t read the post on defining “Enough” yet, this is where the two ideas lock together

Why “Emergency Fund” Is the Wrong Name
This is why I don’t love the term emergency fund.
“Emergency” sounds like disaster.
Like the house is on fire and we’re running for the exits.
But most of what disrupts our finances isn’t an emergency.
It’s life.
The appliance that dies.
The medical bill you didn’t see coming.
The car repair that can’t wait.
These aren’t emergencies.
They’re the friction of living.
I prefer to think of this money as a buffer.
A buffer doesn’t exist because something has gone wrong.
It exists so that when life slows down or swerves, you don’t crash.
People often associate emergency funds with job loss, and that’s a real and important concern.
But notice what the fund actually does in that moment.
It doesn’t fix everything.
It doesn’t solve the situation.
It buys time.
Time to keep paying for your priorities.
Time to breathe.
Time to figure out what comes next without panic.
Seen this way, job loss isn’t a separate category.
It’s simply the largest version of the same thing a buffer is designed to handle.
What the Buffer Is Really Protecting
The goal of this system isn’t control.
It’s continuity.
A buffer allows you to keep your priorities funded and your passions alive, even when something unexpected appears in front of you.
This money isn’t there to prepare for disaster.
It’s there to protect your time.
Time to slow down instead of crash.
Time to stay on the path you chose.
Time to respond instead of react.
Forget the emergency fund.
Build a buffer.
Not because life is a disaster waiting to happen, but because life is dynamic.
There don’t need to be emergencies.
There need to be contingencies.
And when you design for that, your plan doesn’t fall apart when life shows up.
