The short answer
Track leads, cost per lead, booking rate, show rate, trial-to-enrollment rate, cost per enrolled student, monthly cancellations, average membership length, and monthly recurring revenue. Together they show exactly where a school is leaking growth.
You cannot fix a funnel you cannot see. These nine numbers take about 20 minutes a month to update and will tell you whether your problem is traffic, follow-up, sales, or retention.
Acquisition
- Leads per month: total new inquiries from all sources. Track sources separately.
- Cost per lead: ad spend divided by leads. Healthy is usually under $20.
- Booking rate: booked trials divided by leads. Target 50% or better. Low numbers here mean a follow-up problem, not an ad problem.
Conversion
- Show rate: trials attended divided by trials booked. Target 70% with reminders in place.
- Trial-to-enrollment rate: enrollments divided by trials attended. Target 40% or better.
- Cost per enrolled student: total marketing spend divided by new students. This is the only acquisition number that matters at the end of the month.
Retention and revenue
- Monthly cancellations: keep it under 3% to 5% of active students.
- Average membership length: 12 to 18 months is healthy. Under nine months means the first 90 days need work.
- Monthly recurring revenue: what you actually built. Track net change, not just new sales.
Read the numbers as a chain
Plenty of leads with few enrollments is a follow-up or sales problem. Great enrollments with flat student count is a retention problem. Great retention with no growth is a traffic problem. Fix the earliest broken link first.
Review it the same way every month
- 1Pull the numbers on the first business day of the month.
- 2Compare against the previous three months, not the previous one, so a single odd week does not drive decisions.
- 3Pick one number to improve. One, not five.
- 4Write down the change you are making and the result you expect.
- 5Review it 30 days later before changing anything else.
