Low Enrollment: When to Cancel a Class or Camp Week

Updated September 17, 2026

Cancel a class on a date you published in advance. Set your minimum at break-even plus two kids, tell families the minimum and the decision dates when they register, and refund automatically if the class misses them. Then run closer to break-even than your instincts want, because most families whose program gets cancelled don't come back.

I run Journey to STEAM. We've run programs at 75+ school sites for 2,500+ students, and 95% of our school partners renew. I've cancelled classes too fast and I've held them too long. Here's the system I use now, with the math shown.

When should I cancel a class for low enrollment?

Cancel when enrollment is under your trigger number on your trigger date. Mine are fixed. Below 6 kids at seven days out, the program is cancelled. Below 8 at two days out, the program is cancelled. Every family gets an automatic refund. Those numbers and dates are published before registration opens.

Publishing them does two jobs. It stops you from negotiating with yourself at 11pm when a class is sitting at five. And it makes Friday's decision a policy every family saw in August, so nobody is surprised and nobody has to argue.

I use two checkpoints because families register late. The seven-day check catches the class that's going nowhere. The two-day check catches the one that almost made it, while your instructor and your families still have time to make other plans.

How do I set a minimum enrollment number?

Take your break-even enrollment and add two. Break-even is the fixed cost of the program divided by what you keep per child after card processing and supplies. The two-kid buffer gives you room when a family withdraws after the first session.

Here's a worked example. It's the same 10-week class I use in the guide on how to set camp and class prices, so you can follow the numbers across both. Example figures. Swap in your own.

1. Price: $240 per child, room for 12.
2. Fixed cost: $1,000. Instructor pay for 10 sessions x 1.5 paid hours x $30 = $450, room $250, admin share $300.
3. What you keep per registration: $232.53. On enrops the family pays $247.20 by card, which is the $240 plus a $7.20 enrops service fee. Stripe's standard rate is 2.9% + 30¢ on that total (stripe.com/pricing, checked September 17, 2026), which comes to $7.47. You pay enrops $0.
4. Supplies: $12 per child. Margin per child is $232.53 - $12 = $220.53.
5. Break-even: $1,000 / $220.53 = 4.5, so 5 kids.
6. Published minimum: 5 + 2 = 7 kids.

My own minimums at Journey to STEAM: 8 for a standard after-school class, 10 where tuition is discounted, 12 at sites that cost more to serve. For camps: 8 with one lead instructor, 10 once a second instructor is committed, 12 for a full day. The ceiling is 14 kids per instructor for older kids, 12 for younger ones, and 18 with two instructors. Take those numbers. Adjust them to your costs.

What does cancelling a class really cost?

Cancelling costs you the family. It feels like containing a loss, and the real loss shows up next term, when those parents don't register again.

An operator on my podcast told me he doesn't cancel programs, even at break-even. I thought he was being sentimental. Then I pulled our own records. When we cancelled a program for low enrollment, most of those families didn't buy from us again. He was being correct.

So run the math both ways. Take the class above at 4 kids, one short of break-even.

• Run it: 4 x $220.53 = $882.12 in margin against $1,000 in fixed cost. You're down $117.88 across ten weeks.
• Cancel it: you're down $0 this term, and four families are at risk. If each of them would have registered two more times at $240, that's 4 x 2 x $240 = $1,920 in future tuition.

I'll pay $117.88 to keep four families and a school's Tuesday slot. Below my trigger number the math changes. The loss grows every week and the room stops feeling like a class. That's why the floor exists, and that's why it's a number I picked on a calm day.

How do I fill a thin class before the deadline?

Work the days between your first warning and your trigger date. Most of what fills a thin class costs nothing.

1. Find the families who started and didn't finish. On enrops a reminder goes to them automatically, on the Free plan, from your first registration.
2. Ask the school to resend the flyer or the newsletter blurb, with the date registration closes in the first line.
3. Email families from past terms at that site. Previous participants are one of my most reliable sources of enrollment.
4. Offer a payment plan. Cost is the barrier families tell us about most. Here's how to offer payment plans for camps and classes.
5. Use a discount code for the last few days, if your margin has room. Check it against your break-even first.
6. Merge two thin sections into one day, with the families' okay.
7. Call. People answer the phone. They want to help you. Help them help you.

How do I tell families a class is cancelled?

Tell them the same day, refund in full without being asked, and offer the nearest alternative in the same message. Tell your school partner first. A front office should hear about a cancelled program from you, before a parent calls to ask.

Keep the message short. What was cancelled. That the refund is already on its way. The closest class or day with open spots, with the link. A real name and a reply-to address. No long apology. You followed the policy they agreed to.

Check what your registration tool does with fees on a refund, because families notice the missing dollars. On enrops, the enrops service fee is refunded to the family whenever the registration is refunded. Other tools handle it differently, and I lay that out in what registration software really costs.

Which enrollment rules should I retire?

Retire any rule that blocks the thing it was written to protect. I found one in my own operation, and I'm a careful person.

We had a rule that held scholarships until a section reached its minimum. The logic looked sound. Protect the section's economics first, then be generous. Except cost is the barrier families name most. I had locked the affordability lever until the problem it solves was already solved. I retired the rule.

Rules that live in your head get decided again under pressure, a little differently each time. Rules that live in writing can be read on a calm Tuesday and questioned. Whatever you use for registration, make sure you can see enrollment by section before your cancel date without exporting anything. On enrops the total enrolled sits at the top of every roster and updates as families register. One look against your minimum tells you where you stand. The walkthrough is on how it works.

One more thing, and it's free. Call one other operator this week and ask what their minimums are. That call is worth more than this article.

Frequently asked questions

What is a good minimum enrollment for a camp week?

Mine are 8 campers with one lead instructor, 10 once a second instructor is committed, and 12 for a full-day camp. Build yours from your own break-even plus two.

Should I tell families the minimum before they register?

Yes. Put the minimum and the decision dates in the program description and the confirmation. Families plan their week around your class, and a published date is kinder than a surprise.

Do families get the service fee back if I cancel?

On enrops, yes. The enrops service fee is refunded to the family whenever the registration is refunded. See pricing for the full rules.

Can I run a class below break-even on purpose?

Yes. I do it at a new site when I want those families and that school next term. Decide it ahead of time, know the dollar amount you're spending, and hold your floor.

How much notice do instructors need?

As much as families do. Tell instructors your trigger dates when you offer them the class, so a cancellation at seven days or two days is something they already planned around.
