Completion Rate: Definition & Guide for Creators

The percentage of viewers who watch your video from start to finish.

Completion rate (or retention rate) measures what percentage of viewers watched your entire video. A 60-second video where the average viewer watches 45 seconds has a 75% completion rate. This metric is crucial for short-form video algorithms—TikTok, Reels, and Shorts all heavily favor videos with high completion rates when deciding what to push to the For You Page or recommendations.

Pro Tips for Completion Rate

Here's what experienced creators know about completion rate:

  • Shorter videos often have higher completion rates
  • Add loops or callbacks to encourage rewatches, which count as additional completions on some platforms

Frequently Asked Questions

What's a good completion rate?

For short-form (under 60 seconds): 70%+ is good, 90%+ is excellent. For longer content, rates naturally drop. The key is comparing your completion rate to your own averages—if a video is significantly above or below, analyze why.

Does rewatching count toward completion rate?

Yes, on most platforms. If someone watches your 15-second video twice, that can count as 200% completion. This is why looping videos (where the end connects seamlessly to the beginning) perform well—people often rewatch without realizing.

Should I make shorter videos to get higher completion rates?

Not necessarily. Make videos as long as they need to be. A 15-second video with 90% completion isn't always better than a 60-second video with 70% completion—the longer video kept people engaged 4x longer, which algorithms also value.
