# Peak Intent Score: Maximum Purchase Intent

> The highest purchase intent score reached at any point in a session. Captures the moment of highest buying interest.

<Tip>
  Peak Intent Score captures the maximum purchase intent observed at any point in a session, revealing the moment of highest buying interest.
</Tip>

## Formula

<Info>
  **Peak Intent Score** = **MAX** ( Intent Score ) **per Session**
</Info>

### Formula Components

| Metric                                                              | Definition                                  |
| ------------------------------------------------------------------- | ------------------------------------------- |
| [**Intent Score**](/reference/metrics/funnel/sessions/intent-score) | Real-time purchase likelihood score (0-100) |
| **MAX per Session**                                                 | Highest score reached during the session    |

| Metadata        |                         |
| --------------- | ----------------------- |
| **Type**        | Number                  |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Average                 |

## Example

Sessions reached an average **peak intent of 52/100**, even though final intent averaged only 34.

| Exit Point   | Sessions | Avg. Peak Intent | Final Intent |
| ------------ | -------- | ---------------- | ------------ |
| Checkout     | 2,000    | 85               | 78           |
| Cart         | 3,000    | 68               | 45           |
| Product Page | 4,000    | 42               | 28           |
| Collection   | 3,000    | 25               | 18           |

## How It Works

Peak Intent Score tracks the high-water mark of purchase intent during a session. Even if a visitor's intent drops (e.g., they remove items from cart), the peak captures how close they came to converting. This helps identify "almost buyers."

## When to Use

| Scenario                    | Action                                |
| --------------------------- | ------------------------------------- |
| High peak, low final intent | Investigate cart abandonment causes   |
| Retargeting "almost buyers" | Target visitors with high peak scores |
| Checkout friction analysis  | Compare peak vs. final at each step   |
| Recovery campaign targeting | Focus on high-peak abandoners         |
