Cost Per ThruPlay

Average cost of achieving a ThruPlay (complete view or 15-second watch) for video ads.

Definition

Cost Per ThruPlay measures the average cost to achieve a ThruPlay, which is either a complete video view for content under 15 seconds or a 15-second watch for longer videos. This metric helps evaluate the efficiency of video ad spending in delivering complete messages to viewers.

Examples

$0.02 cost per ThruPlay indicating efficient video delivery

Industry Benchmarks for Cost Per ThruPlay

Typical performance ranges by industry segment. Benchmarks vary by platform, audience maturity, and attribution window — treat these as starting points, not targets.

  • Tier 1 markets (US/UK/CA/AU), prospecting

    Typical range
    $0.03 – $0.10
    Median
    ~$0.05

    The canonical US-DTC range; assumes broad-ish prospecting on Reels/feed.

  • Tier 1 markets, retargeting (narrow audiences)

    Typical range
    $0.08 – $0.25
    Median
    ~$0.15

    Narrow audiences spike CPT; warm viewers complete but inventory is thin.

  • Tier 3 markets (LATAM, SEA, IN)

    Typical range
    $0.005 – $0.03
    Median
    ~$0.015

    Sub-penny CPTs are normal in cheap-CPM geos.

  • DTC Beauty / Apparel (US, prospecting)

    Typical range
    $0.03 – $0.08
    Median
    ~$0.05

    Competitive CPMs offset by strong thumbstop and retention.

  • Supplements / Health (US, prospecting)

    Typical range
    $0.04 – $0.12
    Median
    ~$0.07

    Higher CPMs from policy review and competition; CPT runs higher.

  • Reels (any vertical, US)

    Typical range
    $0.02 – $0.06
    Median
    ~$0.04

    Reels typically delivers the cheapest CPT due to higher 15s completion.

Reach

Reach measures the total number of unique users who have been exposed to an advertisement at least once during a campaign period. This metric is fundamental for understanding campaign scale, audience penetration, and the efficiency of media spend in accessing target audiences. Reach can be measured at various levels including campaign, platform, and total brand reach.

Video Completion Rate (VCR)

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.

Cost Per View (CPV)

Cost Per View measures the average cost of a qualified video view, with platform-specific definitions of what constitutes a billable view. Common view criteria include watching 2-30 seconds, 50% of video in view for 2 continuous seconds, or user-initiated plays. This metric helps evaluate video ad spending efficiency and compare performance across platforms, formats, and campaigns.

View Through Rate (VTR)

View Through Rate (VTR) most commonly measures the share of ad impressions that become platform-counted views: VTR = (counted views ÷ impressions) × 100, with YouTube TrueView counting a view at 30 seconds or completion. In attribution contexts, VTR instead means the share of impressions that led to a conversion without a click. Always confirm which meaning a report uses.

Cost Per Completed View (CPCV)

Cost Per Completed View measures the average cost incurred for each video ad watched to 100% completion — total video spend divided by completed views. It is particularly relevant for brand and storytelling campaigns where the payoff — the logo, offer, or emotional beat — usually lands at the end, so a partial view delivers little value. On some platforms CPCV is a buying model where you're charged only when a view completes; more often it's an effective metric calculated over a CPM or CPV buy, in which case impressions and partial views still consume budget and CPCV simply expresses what each completion cost. Either way it isolates the cost of complete message delivery, complementing exposure metrics like CPM (which prices impressions regardless of watch time) and CPV (which counts partial views).

ThruPlay

ThruPlay is Meta's standard video-view event, counted when a viewer watches a video to 15 seconds — or to completion if the video is shorter. It is both a reported metric and a biddable optimization/billing event, and it replaced Meta's retired 10-second video view. ThruPlays ÷ video plays gives the ThruPlay Rate; spend ÷ ThruPlays gives Cost Per ThruPlay. The term is Meta-specific.

ThruPlay Rate

ThruPlay Rate measures the percentage of video plays where users watch either the entire video (for videos under 15 seconds) or at least 15 seconds (for longer videos). This is the denominator Meta reports against; on Meta, autoplay keeps video plays ≈ impressions. The metric evaluates content's ability to maintain viewer attention and deliver complete messages, particularly important for platforms like Meta and TikTok.

Hold Rate

Hold Rate measures how well a video ad retains the viewers it has already hooked — the share of 3-second video views that go on to reach 15 seconds (or completion for shorter videos). Where Hook Rate (Thumbstop Rate) judges the open, Hold Rate judges the middle: it isolates whether the body of the ad earns continued attention after the scroll-stopping first frames, normalized to the audience that actually started watching rather than to total impressions.

Impressions

Impressions measure the total number of times an advertisement is shown to users, regardless of whether they interact with it. Each time an ad appears on a screen counts as one impression, though viewability standards may require minimum exposure duration or percentage in view to count as a valid impression.

How AdSights helps you track Cost Per ThruPlay

AdSights links Cost per ThruPlay directly to the creative patterns that hold attention through the 15-second threshold — opening hook, mid-ad pacing, demo placement, voiceover cadence. By comparing CPT across variants alongside the retention curve and revenue outcomes, AdSights identifies which creative elements deliver cheap ThruPlays that also convert, versus cheap ThruPlays that don't. Teams use this to brief videos that clear the 15s mark efficiently, reallocate spend toward variants with both strong CPT and strong downstream ROAS, and stop optimizing creative against ThruPlay cost in isolation — the trap of chasing cheap attention that never converts.

Frequently asked questions

Common questions about Cost Per ThruPlay, answered.

What's a good Cost per ThruPlay?
For US DTC prospecting, $0.03–$0.06 is healthy and below $0.03 is excellent. Above $0.10 typically signals weak retention through the 15-second threshold (creative problem) or an overly narrow audience (auction problem). Tier 3 markets routinely run sub-penny CPTs. Always pair CPT with downstream ROAS — cheap attention that doesn't convert is the worst kind of efficient metric.
Is ThruPlay billing better than CPM?
It depends on your goal. ThruPlay optimization filters out impressions that don't clear 15 seconds, which is useful for video-view and awareness objectives where attention matters more than reach. CPM is cheaper and broader. For lower-funnel objectives, neither is the right billing event — optimize for conversions and use CPT as a diagnostic metric, not a billing target.
Why is my CPT so high?
Three common causes: (1) the video is long (30s+) and retention drops before 15s, so few viewers convert to ThruPlay; (2) the audience is narrow and you're paying auction premiums; (3) the hook is weak and Meta has to serve many impressions to find viewers who'll watch through. Cause #1 is by far the most common in DTC — shorten the video or restructure the first 15s before changing audience setup.
CPT vs CPV — are they the same?
No. CPV (Cost per View) historically referred to Meta's 10-second view event, now largely retired. CPT specifically counts the ThruPlay event (15-second or completion). Outside Meta, 'CPV' can mean a 2-second YouTube view or a 30-second TrueView event, so cross-platform CPT/CPV comparisons are usually apples-to-oranges. Always confirm which view event the metric is built on.
Should I optimize for ThruPlay cost or for purchases?
Optimize for purchases if you have 30–50+ weekly conversion events — Meta's conversion optimization beats ThruPlay optimization at driving revenue once the pixel has signal. Use ThruPlay optimization only for awareness or video-view objectives, or as a temporary signal-generation step for new pixels. Optimizing for cheap ThruPlay on a sales campaign typically lowers blended ROAS by acquiring viewers, not buyers.
