Video Completion Rate (VCR) Formulas & Reverse Equations
Use these standard and algebraic reverse formulas in spreadsheets, agency decks, or media plans:
Solve for VCR
VCR = (Total Completed Views ÷ Total Video Starts) × 100Solve for Total Completed Views
Total Completed Views = (Total Video Starts × VCR) ÷ 100Solve for Total Video Starts
Total Video Starts = (Total Completed Views × 100) ÷ VCRUnderstanding Video Completion Rate (VCR)
Video Completion Rate (VCR) — also known as View-Through Rate (VTR) — measures how effectively your video creative holds viewer attention from the opening frame to the closing call-to-action. Pairing VCR with quartile drop-off reporting (25%, 50%, 75%, 100%) pinpoints the exact second viewers lose interest.
When to Use Video Completion Rate (VCR)
Use VCR to evaluate video creative edits, compare 6s vs 15s vs 30s cutdowns, and audit placement quality across CTV, BVOD, pre-roll, and social feeds.
Industry Benchmarks & Planning Context
Non-skippable CTV and BVOD inventory routinely achieves 92%–98% VCR, skippable pre-roll averages 65%–80%, and in-feed social video typically sees 15%–35% VCR.
Frequently Asked Questions About VCR
How do you calculate Video Completion Rate (VCR)?
Divide the number of 100% completed video views by the total number of video starts (impressions where playback began), then multiply by 100: VCR = (Total Completed Views ÷ Total Video Starts) × 100.
How can I improve my Video Completion Rate?
Front-load your brand hook and motion in the first 2 seconds, tighten 30-second edits down to 15 or 6 seconds for mobile feeds, add clear burned-in captions for sound-off environments, and exclude low-quality in-banner video placements.
