Online Course Completion Rates: Benchmarks and Fixes
Free online courses famously lose most of their students. What the research says about completion, why paid courses differ, and nine changes that help students finish.
Students who finish your course get the outcome, leave good reviews and buy again. Students who stall ask for refunds or quietly forget you. Completion is the number that connects teaching to revenue.
Here's what the best-known research found about online course completion, why it doesn't map neatly onto a paid course, and nine changes that help more students reach the end.
The short answer
Completion rates for free, open online courses are very low: a study of MIT and Harvard MOOCs found about 3% of 2017–18 enrollees completed. Paid students finish far more often, but many still stall. To raise completion, promise one specific outcome, keep lessons short, add practice and quizzes, unlock lessons in order, and follow up with students who stop.
Key takeaways
- Reich and Ruipérez-Valiente found only about 3% of enrollees in MIT and Harvard MOOCs completed in 2017–18.
- Learners who paid for a verified certificate completed far more often than those who didn't.
- Measure your own course: track completion by lesson to see where students stop.
- Short lessons, practice, early wins and reminders do the most for completion.
- Completion is a goal for skill courses; for reference courses, usage matters more.

What is the average online course completion rate?
For free open courses, very low. Justin Reich and José Ruipérez-Valiente analyzed MIT and Harvard courses on edX for Science in 2019 and found completion fell to about 3% of enrollees in 2017–18. Among learners who paid for a verified certificate track, completion was much higher, though still far from universal.
There's no reliable public benchmark for small paid courses, because platforms don't publish comparable data. Treat any single "average completion rate" figure you see with caution, and compare your course with itself over time.
How do you measure your course's completion rate?
Completion rate = students who finished every required lesson ÷ students enrolled, for a group who enrolled long enough ago to have finished. More useful still is the per-lesson view: the share of enrolled students who completed each lesson. The lesson where the line drops is where to look first.
Nine ways to get more students to finish
- Promise one specific outcome. Vague courses lose people; "publish your first 10 recipes" gives them a finish line.
- Keep videos short. Engagement drops after about six minutes. See how long course videos should be.
- Give an early win in the first lesson: something students make or fix in 15 minutes.
- Add practice and quizzes after lessons; retrieval practice helps learning. See writing quiz questions.
- Unlock lessons in order or drip them, so students don't skip ahead and get lost. See drip vs all-at-once.
- Show progress in the course player and celebrate module completions.
- Email students who stall, for example 7 days after their last lesson, with the next step and a link straight to it.
- Add people: a community, lesson discussions or a cohort with live calls. See cohort vs self-paced.
- Reward the finish with a certificate. See course certificates.
Is a low completion rate always bad?
Not always. Some buyers want one module, or use the course as a reference. If students get what they came for and leave good reviews, a lower completion rate can be fine. It's a problem when students drop at the same lesson, ask for refunds or say they got lost.
Frequently asked questions
Why do so many students not finish online courses?
Common reasons are a vague outcome, long videos, no practice, no deadline or schedule, no contact with other people, and simply getting busy. Most are fixable in the course design.
Do paid courses have higher completion rates than free ones?
Generally, yes. In the MOOC research, learners who paid for a verified certificate completed far more often than free learners.
What completion rate should I aim for?
Compare your course with itself: track completion by lesson, fix the biggest drop, and check whether the next group does better.
Do reminder emails improve course completion?
They help bring stalled students back, especially when the email names the next lesson and links straight to it.
Where Klasira fits
Klasira's course insights show enrollments, completion rate and how many students finish each lesson, and every student is a CRM contact, so you can email the ones who stall. Start your school or see pricing.
