Hook Rate Formula: How to Calculate It [+ Benchmarks]
Hook Rate = 2-sec views / impressions. Learn how to calculate it for TikTok, Meta and Facebook Ads with benchmarks.
Hook rate is one of the most important metrics for video ads on TikTok and Meta. It tells you whether your creative actually stops the scroll — which is the single biggest predictor of whether an ad can scale profitably.
This guide answers the three questions people most often ask: What is Hook rate? What is the formula? How do I calculate it?
Hook rate definition
Hook rate is the percentage of viewers who keep watching past the first few seconds of a video ad — usually measured at the 2-second or 3-second mark. It is a retention metric for the opening of your video.
In plain English: "Of all the people who saw this ad, how many did not swipe away in the first 2 seconds?"
Hook rate formula
TikTok uses a 2-second threshold because its feed is aggressive and attention decays fast; Meta uses 3 seconds because that is their official definition of a "video view".
How to calculate Hook rate (step-by-step)
Let's say your TikTok ad has:
- Impressions: 50,000
- 2-Second Video Views: 18,000
Applying the formula:
Hook Rate = (18,000 ÷ 50,000) × 100% = 36%
That is a solid "average to good" result. You can now compare it against your own account baseline and decide whether to scale, iterate on the opening, or kill the creative.
Why Hook rate matters for scaling
- It is the earliest quality signal. You can judge Hook rate within hours, long before CPA stabilizes.
- It predicts CPM efficiency. TikTok and Meta algorithms reward videos with strong early retention by lowering effective CPM.
- It reveals creative problems fast. A weak hook can kill even the best offer.
What counts as a good Hook rate?
As a working baseline for most performance accounts:
- Below 20% — poor; the opening is not stopping the scroll.
- 20–40% — average; usable for testing, room to improve.
- 40–60% — good; consistent attention capture.
- 60%+ — excellent; scale candidates.

Hook rate vs Hold rate
Hook rate captures attention. The hold rate formula tells you whether the content keeps it. Used together, they form the backbone of creative diagnostics — see Hook Rate vs Hold Rate for a full framework.
Common Hook rate mistakes
- Judging Hook rate in a vacuum. Always look at it together with CTR, CPA and ROAS.
- Comparing across platforms. TikTok 2-second and Meta 3-second Hook rates are not directly comparable.
- Killing creatives too early. Give enough impressions for statistical confidence before pulling the plug.

FAQ: Hook Rate Formula: How to Calculate It [+ Benchmarks]
- What is Hook rate in simple terms?
- Hook rate is the percentage of people who keep watching your video ad past the first 2–3 seconds. It measures how well the opening of your creative stops the scroll and earns the next second of attention.
- What is the Hook rate formula?
- On TikTok: Hook Rate = (2-Second Video Views ÷ Impressions) × 100%. On Meta: Hook Rate = (3-Second Video Plays ÷ Impressions) × 100%. Multiply by 100 to express it as a percentage.
- How do I calculate Hook rate from my dashboard?
- Take the 2-second (TikTok) or 3-second (Meta) video view count, divide by total impressions, and multiply by 100. For example, 18,000 2-second views on 50,000 impressions equals a 36% Hook rate.
- Is Hook rate the same as Thumb-stop rate?
- They measure the same concept — retention past the opening of a video. Thumb-stop rate is the term Meta popularized, while Hook rate is more common in the TikTok and performance creative communities.
