One missed follow-up looks small. The annualized cost across a school's worth of trials is the most underestimated line item in the business. Below is the math, from first principles.
Start with one trial
You run a trial class. The student doesn't come back. There are two ways to think about what happened.
The first is: "they weren't a great fit anyway." This is usually self-soothing. Of all the trials you've ever lost, what fraction would you guess were genuinely poor fits? Be honest. Most schools land between 30% and 50%.
The other half were recoverable. They liked the class. The parent thought it was nice. They went home, life happened, and nothing pulled them back.
The lifetime value of one student
Run this with your real numbers if you can. Here's a typical shape:
- Average monthly tuition (after family discounts): $135
- Average tenure: 22 months
- Lifetime tuition revenue: $2,970
- Plus: belt test fees, retail, parties, seminars: roughly $250 over tenure
- Plus: ~30% chance of a sibling joining within 6 months
Round numbers, one enrolled student is worth roughly $3,500 to $4,000 in direct revenue, plus a meaningful chance of a second family member. Call it $4,500 expected value, conservatively.
The cost of one missed follow-up
Assume one trial student per month who would have enrolled with better follow-up doesn't. Twelve a year. At $4,500 expected value each:
$54,000 a year. From one missed follow-up a month. At a 200- student school doing 10 to 15 trials a month, that's the difference between "doing fine" and "growing comfortably."
And this is the cautious estimate. If two recoverable trials slip per month, you're closer to $100,000 a year. If your tuition or tenure is higher than the example, it's more.
Why staff intuition is wrong about this
Ask your front desk or your assistant if trial follow-up is working well. They'll say yes, because they remember the ones they did follow up on. The ones they forgot don't form memories. The lost trials are invisible to the people who would have caught them.
The owner usually has the same problem in reverse. You see the ones who enrolled. You don't see the silent attrition. The numbers are perfectly capable of looking fine while you bleed recoverable trials every month.
What good follow-up actually costs to run
Three things you have to spend on, regardless of software:
- One person, partial-time. Front desk, you, or a parent. Maybe 4 to 6 hours a week.
- A list of leads in one place. Not a phone, not a chat, not three sticky notes. One place.
- A short cadence. First touch in 5 minutes. Same-day post-trial. Day-3 nudge. Day-7 last touch. Mark cold with a reason.
That's it. Run that for 90 days and you'll see the conversion rate move. If you're already running it and your numbers aren't moving, the problem is somewhere upstream (lead quality, trial experience, pricing), not the follow-up workflow.
The minimum-viable upgrade
If you do nothing else this quarter, do this:
- One person owns trial follow-up. One. Written on a sticky note next to their desk.
- Every trial gets a same-day touch within 4 hours of class.
- Every cold trial gets marked with one of four reasons (price, schedule, location, "other"). The reasons go into a tally.
By month 3, you'll know if your trials are leaking for a structural reason (everyone says "price") or a follow-up reason (everyone went silent). The fix is different in each case. You can't fix what you can't see.
One closing reframe
Trial follow-up is not a marketing task. It's an operations task. It runs on a clock and it follows a checklist. Most schools improve their numbers more from this one shift in framing than from anything they spend on ads.
