I didn’t learn this one from a book. I built it because I had to.
Twenty years self-employed. Twenty years of feast months and famine months, showing up whether I was ready or not.
This one’s for the self-employed crowd specifically. Not the W-2s. You. The person whose paycheck changes shape every month.
There’s a second account you need. Not instead of your emergency fund. In addition to it.
This is what I teach every client. Not because it sounds good. Because I’ve lived it and I know it works.
What Actually Counts as an Emergency?
Every finance book on the planet will tell you to have an emergency fund.
Almost none of them will tell you what actually counts as an emergency.
So let’s define it.
If you have a job with a steady paycheck, your emergency fund is for the thing that pops up out of nowhere. The car repair. The appliance that dies on a Tuesday. Job loss.
Three to six months of expenses. That’s the standard advice.
Nine-plus if your job is unstable, or specialized enough that finding the next one could take a while.
Good advice. For a W-2.
Here’s what nobody puts in the book:
If you’re self-employed, you need that emergency fund too. And you need something else.
A runway fund.
Why Self-Employed Income Needs a Second Account
I don’t want you hoping that you have enough income every month. Hope is not a plan. And it’s stressful.
You want to be able to plan months in advance and spot issues while you still have time to adjust your sail.
Simply put, you need to plan your paychecks in advance, the same way an employer would, except the employer is you.
Here’s the trap a lot of self-employed people fall into instead: every time a slow month hits, they raid the emergency fund.
It’s emotionally defeating, watching your safety net shrink every time business is quiet instead of when something’s actually broken.
And here’s the part that should scare you a little:
What happens when a slow month and a real emergency hit at the same time?
If your emergency fund has been covering your slow months, it’s not there when the actual emergency shows up.
So. Two accounts. Two jobs.
Your emergency fund is for the fire. Your runway account is for projecting your income out into the months ahead, so you’re never standing there guessing what’s coming.
How to Build Your Runway Account
Here’s how you build it:
Figure out your Survive Number. What it actually costs to keep your life running, bare minimum.
Figure out your Thrive Number. Survive, plus the stuff that makes life worth living.
Then every time income comes in, a portion of it goes into your Runway Account for future paychecks. You want this money separate from your business operating account and your taxes — its own space, doing its own job.
From there, you pay yourself. And you should always be able to answer one question fast: how many months of runway do I have right now?
This isn’t just for the self-employed. Commission. Bonuses. Anyone whose income looks more like a roller coaster than a straight line.
If this is new to you, you’re starting from zero, and that’s fine. Tighten up for a stretch and stack money into that account like it’s the most important bill you pay. Because it is.
How Much Runway Do You Actually Need?
Depends on your income. Is it fairly steady year-round? Or does it come in bigger chunks, less often? Seasonal, with a seven-month year and a five-month drought?
The shape of your income determines the size of your runway. Not a rule of thumb from a book that’s never met your business.
Now imagine this:
You open your accounts and you know, instantly, that you have eight months of runway.
Eight months.
How differently do you operate a slow month with that number in your head?
You’re not chasing a client because you’re scared. You’re not discounting your rate out of desperation. You’re not lying awake doing math at 11pm.
You’re just building. Because the roof isn’t caving in.
If you don’t have a runway fund, I challenge you to set one up and try it for 90 days. If it doesn’t give you peace of mind, you can go back to hoping. I don’t think you will.
So now I’m curious:
Emergency fund. Runway fund. Do you actually have both, or have you been asking one account to do two jobs?
If that’s you, I’m here.
P.S. If earmarking all of this in separate accounts sounds like a headache, look into Relay. It’s the business bank I use to keep everything in its own lane without opening six accounts at six different banks. No affiliate link here, I just like the tool.
Frequently Asked Questions
Is a runway fund the same as an emergency fund? No. An emergency fund covers the unexpected — a car repair, a job loss, a broken appliance. A runway fund covers the expected reality of variable income: the slow months that are part of running your own business, not an emergency at all.
How much should a self-employed person keep in an emergency fund? The standard advice is three to six months of expenses, and nine or more if your work is unstable or highly specialized. That number is separate from your runway fund, which is sized around the actual shape of your income rather than a general rule of thumb.
How do I know how much runway I have? Divide what you have set aside in your Runway Account by your monthly Survive Number. The result is how many months you could pay yourself if income stopped entirely tomorrow.
Should self-employed people keep business and personal runway separate? Yes. Your Runway Account should be separate from your business operating account and separate from your tax savings. Each account has one job, and blending them makes it harder to know what any of the money is actually for.
