# Video Completion Rate Calculator | VCR Formula & Benchmarks Find what percentage of viewers watch your video to the end, with full retention and drop-off context. Works from YouTube, Vimeo, TikTok, and Facebook analytics data — completion rate benchmarked against platform averages. ## What is video completion rate? Video completion rate (VCR) is the percentage of views that reach the end of the video: **completion rate = (viewers who finished ÷ total views) × 100**. If 1,000 people start your video and 250 watch to the end, your completion rate is 25%. ## How Completion Rate is Calculated This calculator derives completion rate from your platform retention data along with where, specifically, viewers are dropping off — so you can see not just the final number but what pulls it down. It surfaces completion rate, the full retention curve, and per-segment drop-off together. ## Frequently Asked Questions ### How do you calculate video completion rate? Completion rate = (viewers who finished ÷ total views) × 100. This calculator derives it from your platform retention data along with where viewers drop off. ### What is a good video completion rate? It depends heavily on length and platform. Short videos (≤15s) often see 40–50% completion; videos up to a minute commonly land at 20–30%; longer videos frequently fall to 10–15% or lower. The calculator compares your completion rate against the platform-and-length-appropriate average. ### Is video completion rate the same as VCR or view-through rate? They overlap but are not identical. "Video completion rate" and VCR usually mean the share of viewers who watch to 100%. "View-through rate" (VTR) is sometimes used the same way and sometimes for the share of impressions that led to a completed view in an ad context. Definitions vary by platform. ### How is completion rate different from retention and drop-off? Completion rate is a single endpoint — the percentage still watching at the finish. Retention is the full curve of how that audience declines across the whole video, and drop-off is the rate of loss within each segment. Completion rate tells you the outcome; retention and drop-off tell you where and why you lost people. ## Related Tools - [Video Drop-off & Retention Calculator](/resources/tools/calculators/video-dropoff-calculator.md) - Analyze where viewers stop watching - [CPV Calculator](/resources/tools/calculators/cpv-calculator.md) - Calculate cost per view - [ROAS Calculator](/resources/tools/calculators/roas-calculator.md) - Calculate return on ad spend ## Get Started Ready to calculate your video completion rate?
