EdTech Metrics Calculator: CAC, Conversion, Completion & Course Margin

Test the unit economics of a course or programme. Enter leads, paid enrolments, price, marketing spend, delivery cost, refunds, completion and repeat purchase rate to see CAC, margins and LTV:CAC.

QUICK ANSWEREdTech CAC = marketing and sales spend ÷ paid enrolments. Course gross margin = price after refunds − delivery cost per learner. If CAC is higher than the first-course margin, growth only pays back through repeat purchases or referrals; low completion usually means higher refunds and weaker referrals.

What changed in EdTech economics

After 2022, EdTech investors moved focus from user numbers to profitable cohorts: completion, outcomes (jobs, exam results), refunds and repeat purchase. Expensive sales-led models with loan-linked enrolments face regulatory and reputational risk.

Cohort-based, mentor-led formats usually cost more to deliver but improve completion and word of mouth, lowering blended CAC over time.

Frequently asked questions

What is a good course completion rate?

Self-paced online courses often see low completion; cohort or mentor-led programmes can reach much higher levels. Track it by cohort and compare your own trend.

How do I calculate EdTech CAC?

Divide total marketing and sales cost, including counsellor salaries, by the number of paid enrolments in the same period.

Why does completion matter to investors?

It predicts refunds, reviews, referrals and repeat purchases, which drive long-term unit economics.
