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

Campaign achieving $0.05 cost per ThruPlay vs $0.08 benchmark

Optimization reducing cost per ThruPlay from $0.10 to $0.06

Calculation

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.

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.

ThruPlay Rate

ThruPlay Rate measures the percentage of video ad impressions where users watch either the entire video (for videos under 15 seconds) or at least 15 seconds (for longer videos). This metric helps evaluate content's ability to maintain viewer attention and deliver complete messages, particularly important for platforms like Meta and TikTok.

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.
