The VCR formula
VCR = (Complete Views ÷ Video Starts) × 100
- Complete Views — views that reached 100% of the video's duration
- Video Starts — views that began playing (some platforms report against impressions or 3-second views instead — see step 2 below)
If 1,000 people start your video and 250 watch to the end, VCR = 250 ÷ 1,000 × 100 = 25%.
How to calculate video completion rate, step by step
- Pull the two inputs from your platform report. You need complete views (watches to 100%) and total plays. On Meta these are "Video plays" and "Video plays at 100%"; on YouTube use video plays and the 100% quartile from audience retention; on TikTok use video views and "Watched full video".
- Check the denominator definition. Meta autoplays in feed, so plays sit close to impressions; YouTube reports quartiles against plays; TikTok counts a play almost immediately. Never mix a completions number from one report with a plays number from another.
- Check the numerator threshold. VCR uses 100% completions. Meta's ThruPlay (15-second watch) is a billing metric, not a completion metric — using it in the numerator inflates VCR (see the worked example).
- Divide completions by plays and multiply by 100. That's your VCR.
- Benchmark against the same platform, placement, and length band. A 60-second skippable pre-roll and a 12-second Reel are different games — see the table below.
Worked example 1: 30-second Meta ad
- Impressions with a 3-second view: 50,000
- ThruPlay (15-second watch): 7,500 — a separate Meta billing metric, not VCR
- Views to 100% completion: 5,000
- Completion rate = 5,000 ÷ 50,000 × 100 = 10%
For a 30-second creative, 10% completion is below the Meta average for that length (~20–25% for prospecting). ThruPlay (15%) can look healthier than true end-to-end completion — always use 100% completions in the VCR numerator. The retention curve typically shows the steepest drop in the first 3 seconds — hook problem, not mid-roll problem.
Worked example 2: 30-second YouTube skippable in-stream ad
- Video plays: 80,000
- Views reaching the 100% quartile (audience retention report): 16,000
- Completion rate = 16,000 ÷ 80,000 × 100 = 20%
20% sits inside the normal 15–30% band for skippable 30s+ in-stream, where most viewers skip at second 5. Note the trap: YouTube counts a billable TrueView view at 30 seconds or completion — that is a payment threshold, not your VCR numerator. Quartile reporting is where completion comes from.
Video completion rate benchmarks by placement & format

Long-form skippable (60s+) drops further, to roughly 2–10%. As a rule of thumb on skippable formats, every additional 15 seconds of length costs ~15–20 points of completion.

See ThruPlay rate in the glossary for Meta-specific billing rules. Compare your completion rate against platform norms with the ThruPlay Rate Benchmark analyzer, and read Hold Rate vs ThruPlay Rate when diagnosing whether the hook or mid-roll is the bottleneck.
Common mistakes
- Mixing denominators — a VCR computed against 3-second views will always beat one computed against impressions; state the denominator when you report the number.
- Comparing completion across different video lengths — a 60s ad will always score lower than a 15s cut.
- Using ThruPlay or impression-based VTR as completion rate — thresholds and denominators differ.
- Ignoring the first 3 seconds — most drop-off happens before the hook lands.
- Benchmarking organic YouTube against paid Meta — different viewer intent.
- Optimizing for completion alone — a 5s loop can score 80% but drive zero conversions.
How to use this calculator
- Select your platform (YouTube, Meta, TikTok, etc.) for length-appropriate benchmarks.
- Enter retention at key breakpoints from your analytics export (or total views + completions).
- Read completion rate and the retention curve — identify the steepest drop segment.
- Compare to the platform benchmark row for your video length.
- Use the Video Drop-off Calculator for deeper segment analysis.
How to improve video completion rate
- Front-load the hook — value proposition in the first 2 seconds.
- Match length to placement — 15s for feed, 30s max for cold prospecting.
- Cut dead air — pattern interrupts every 3–5 seconds on social.
- Caption everything — 80%+ watch muted on feed.
- Test the thumbnail/first frame — it sets completion before play starts.
- Retarget viewers who hit 50%+ — they are your warm audience.
Methodology & sources
Completion rate benchmarks vary by length and placement — never compare a 60s YouTube pre-roll to a 15s Reels hook. VCR uses 100% completions in the numerator; ThruPlay (Meta) is a separate 15-second billing threshold. The benchmark table above mirrors the source-attributed ranges maintained in the AdSights glossary.

Video Completion Rate
Video Completion Rate measures the percentage of video ad impressions that are watched to 100% completion. This metric helps evaluate creative engagement, message delivery effectiveness, and audience targeting accuracy while accounting for video length and placement quality. VCR is particularly important for brand messaging where full creative viewing is crucial.
Churn Rate
Churn rate measures the proportion of customers who discontinue their relationship with a company during a specific timeframe. For subscription businesses, this means cancellations or non-renewals. For non-subscription businesses, churn is often defined as no purchase activity within a set period. It's a critical metric for evaluating customer retention and business health.
Moving Average
A moving average is a statistical calculation that creates a series of averages from different subsets of data over time. By recalculating the average over a sliding window — commonly 7 or 28 days for ad data — it separates trend from noise, smoothing out short-term fluctuations and random outliers in metrics like CPC, CTR, or ROAS. Daily platform numbers are often too volatile to act on directly; the moving average is the version you can actually make decisions on.
