Video Completion Rate Calculator questions

What is video completion rate?

Video completion rate is the percentage of video starts or impressions that reach the 100% completion event. It helps teams understand whether the full ad earns enough attention to carry the message and CTA.

What is the video completion rate formula?

The video completion rate formula is 100% video completions divided by video starts or impressions, multiplied by 100. Use starts when the ad platform reports them cleanly, or impressions when you want completion rate against all delivered ad impressions.

How do you calculate video completion rate?

Divide 100% video completions by the selected base count, then multiply by 100. If 20,000 people complete a video from 100,000 starts, the video completion rate is 20%.

Should I use impressions or video starts?

Use video starts when the platform gives you a clean start count. Use impressions when you want completion rate against all delivered ad impressions or when starts are unavailable.

What do quartile drop-offs show?

Quartile drop-offs show where viewers leave between the start, 25%, 50%, 75%, and 100% completion. Early drop-off usually points to hook issues, mid-video drop-off points to body pacing, and late drop-off points to CTA or ending issues.
