A few months back, a group practice owner sat down with us after what looked like a fantastic month. Revenue was up. New clients kept coming in.
Then, the week before payroll, she opened her bank account and her stomach dropped — there was way less in there than she expected. She'd been looking at that balance like it was hers to spend, and it wasn't.
Honestly? Having the right cash reserves for your therapy practice would have turned that scary week into a total non-event. She should've been asked, or asked herself "How much should you keep in cash reserves for your therapy practice?"
If you've ever stared at your bank balance the week before payroll and quietly done the math in your head, take a breath — you're in good company. Almost every owner we work with has had that exact moment. And here's the encouraging part: this is one of the easiest problems in your whole business to fix. It really comes down to a single habit — keeping a little cushion of cash set aside.

Why a Cushion Matters More Than You'd Think
Here's the thing about running a practice: your bills are predictable, but your income isn't. Payroll shows up every two weeks no matter what. Rent, software, and benefits don't take a month off. But insurance pays you on its own timeline, a therapist takes some surprise time off, or three paydays sneak into the same month — and suddenly your "normal" month looks nothing like normal.
When there's no cushion, every one of those little bumps turns into a stressful scramble. We've watched owners put off decisions they were clearly ready for — hiring a therapist they needed, opening a second office their waitlist was begging for — just because they were nervous about cash they didn't actually need to worry about. Cash reserves for your therapy practice aren't only there for emergencies. They're what give you the confidence to grow.
It helps to name the usual suspects, because almost none of them are actually surprises. That "third paycheck" month sneaks in twice a year when you pay every two weeks. A big insurance company drags its feet for a few weeks. A therapist leaves and takes some revenue with them while you hire a replacement. A yearly insurance bill or license renewal lands all at once. Any one of these is no big deal on its own — but land one on a thin bank balance and you're suddenly pulling from your own pocket to cover the business. A reserve is just how you stop taking those hits personally.
Think of it this way: a cushion lets you make decisions from a calm, clear place instead of a panicked one. That one shift changes how the whole practice feels to run.
How Much Do You Really Need...Cash Reserves for Your Therapy Practice
Our simple rule of thumb: keep 6 to 8 weeks of your running costs set aside in a separate account.
By "running costs," we just mean the bills that don't stop — payroll, rent, software, benefits, all the stuff that shows up whether or not a single client books that week. (You'll sometimes hear bookkeepers call this your "operating expenses." Same thing, no fancy term needed.) Add those up for a normal month, then multiply by one-and-a-half to two. That number is your reserve goal.
A few things to adjust for:
- If most of your money comes through insurance, aim for the higher end. There's often a 30-to-60-day gap between seeing a client and actually getting paid for it, and your reserve is what carries you across it.
- If your income has slow seasons — quieter summers, a holiday dip — build your cushion around your leanest stretch, not your average month.
- Keep the money in a separate account, not your everyday checking. Cash you can see is cash you'll find a reason to spend. Tuck it out of sight and it stays put until you truly need it.
This is a big reason so many of our clients run Profit First in their practice. Splitting your money into separate accounts for separate jobs means "payroll is covered" becomes something you can actually see — not just a hope you're carrying around in your head. Profit First can help with the structure of how to do this. We've run it at Navigator for 8 years, it's a game-changer.
How to Build Your Cushion Without Feeling It
If your reserve is sitting at zero right now, that goal can feel a long way off. It isn't. You build it the same way you'd build any savings — a little at a time, on autopilot, so you barely notice it leaving. Here's the approach we walk our clients through:
- Start with one week, not eight. Set a small, doable first goal: just one week of costs covered. Hitting it fast feels great and proves the whole thing works.
- Treat the reserve like a bill. Move a set slice of every deposit — even 2 to 3% — into savings the moment money lands. Make it as non-negotiable as rent.
- Save your good months. When you have a great month, it's tempting to pay yourself more. Instead, send some of that extra straight to the reserve. Your strong months are what carry you through the slow ones.
- Put it on autopilot. Set up an automatic transfer so you're not relying on remembering (or on willpower). The best money habits are the ones you never have to think about.
- Check your number every few months. As your payroll grows, your costs grow too — so your "6 to 8 weeks" number will creep up. Revisit it each quarter so your cushion keeps pace with the practice.

When to Use Your Cushion (and When to Leave It Alone)
A reserve only works if you respect it. It's there for two things: timing gaps and real emergencies. A third-paycheck month, a slow insurance stretch, a piece of equipment that breaks — that's exactly what it's for. You dip in, you refill it, you move on. No guilt.
What it's not for is quietly covering the same shortfall month after month. If you're reaching into it every single month, the reserve isn't your problem — it's a flashing warning light. Usually that means your pay structures or the cost of delivering your services need a second look, and no amount of savings will fix a setup that loses money every month.
The healthiest practices treat that reserve like a line they don't cross. They know their number, they keep it topped up, and they only touch it on purpose.
Where Should You Keep Your Cash Reserves?
Once you've decided to build a cushion, the next question is where the money should actually live. You want it somewhere you can reach in a real pinch, but separate enough that you're not tempted to treat it like spending money.
A high-yield savings account is usually the sweet spot — that just means a savings account that pays a bit more interest than a regular one. Your cash reserves for your therapy practice should earn a little something while they sit there, but the goal is keeping the money safe and easy to grab, not growing it — this isn't cash you invest or lock away. A lot of owners take it one step further and open that account at a different bank than their checking. The few extra clicks it takes to move money over is just enough of a speed bump to stop the "I'll just borrow from it this once" moment.
Whatever you pick, keep it boring on purpose. The whole point of cash reserves for your therapy practice is that the money's just sitting there, untouched, ready the moment a surprise bill or a slow month shows up.
The One Question to Ask Yourself
Here's the gut check we leave every owner with: "If my revenue dropped 20% next month, could I still make payroll without losing sleep?"
If the answer's yes — you've built something genuinely solid. If it's no, or "honestly, I'm not sure," that's not a failure at all. It just means you've found your starting point, and now you know exactly what to work on first.
Cash reserves aren't about hoarding money or running your practice scared. They're about buying yourself the freedom to lead with a clear head. When you know payroll's covered six weeks out, you make calmer hiring calls, you're not negotiating from a place of worry, and you sleep a whole lot better. That peace of mind is worth way more than any interest you'd earn leaving the money somewhere else.
