# Cost Per ThruPlay

**Category:** metrics  
**Short Description:** Average cost of achieving a ThruPlay (complete view or 15-second watch) for video ads.  
**Last Updated:** 2026-05-16T12:00:00Z

## 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.

## Formula

**Formula:** `CPT = Total Ad Spend / ThruPlay Events`
**Result Unit:** $

Cost per ThruPlay (15-second view or full completion of a shorter video). Meta-specific billing model.

## Calculation

**Formula:** `Total Ad Spend / Total ThruPlays`

**Explanation:** Divide total advertising spend by number of ThruPlays achieved. Provides cost efficiency metric for delivering complete video messages.

### Components

- **Total Ad Spend**: Total advertising cost for the campaign
- **Total ThruPlays**: Number of complete views or 15-second watches

## Industry Benchmarks

| Segment | Typical Range | Median | Notes |
| --- | --- | --- | --- |
| Tier 1 markets (US/UK/CA/AU), prospecting | $0.03 – $0.10 | ~$0.05 | The canonical US-DTC range; assumes broad-ish prospecting on Reels/feed. |
| Tier 1 markets, retargeting (narrow audiences) | $0.08 – $0.25 | ~$0.15 | Narrow audiences spike CPT; warm viewers complete but inventory is thin. |
| Tier 3 markets (LATAM, SEA, IN) | $0.005 – $0.03 | ~$0.015 | Sub-penny CPTs are normal in cheap-CPM geos. |
| DTC Beauty / Apparel (US, prospecting) | $0.03 – $0.08 | ~$0.05 | Competitive CPMs offset by strong thumbstop and retention. |
| Supplements / Health (US, prospecting) | $0.04 – $0.12 | ~$0.07 | Higher CPMs from policy review and competition; CPT runs higher. |
| Reels (any vertical, US) | $0.02 – $0.06 | ~$0.04 | Reels typically delivers the cheapest CPT due to higher 15s completion. |

## How AdSights Helps

**Tracking 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.

## FAQs

### 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.
