Excellent. Most viewers are watching to the end, which strongly favors wider reach.
What Is TikTok Completion Rate?
Completion rate is the percentage of your video that the average viewer watches. It is found by dividing your average watch time by the full length of the video. If a 20-second video has an average watch time of 14 seconds, the completion rate is 70%. In TikTok’s native analytics this metric can climb above 100% when viewers loop or rewatch the video, which is one of the clearest signs of a magnetic hook.
How to Calculate Completion Rate
The formula is simple: (Average Watch Time / Video Length) × 100. Pull your average watch time from the analytics tab on any video, divide it by the video’s length, and multiply by 100. Because shorter videos are easier to finish, compare completion rates between videos of similar length for the most useful read.
Why Completion Rate Drives Reach
TikTok’s recommendation system rewards videos that hold attention. A higher completion rate tells the algorithm your content is satisfying, which makes it more likely to be pushed to new viewers on the For You Page. To raise it, strengthen your first few seconds, keep the pacing tight, and cut any dead air. Pair this with your engagement rate for a fuller picture, and read our TikTok video analysis guide to learn what else to look for.
