# TikTok Cost per Initiate Checkout: Checkout Acquisition Cost

> Track TikTok Cost per Initiate Checkout to measure spend efficiency for driving checkout starts. Lower values indicate better bottom-of-funnel ad performance.

<Tip>
  TikTok Cost per Initiate Checkout measures the average spend per checkout started from your TikTok ads.

## Formula

<Info>
  **TikTok Cost per Initiate Checkout** = **TikTok Ad Spend** ÷ **TikTok Initiate Checkouts**

### Formula Components

| [**TikTok Ad Spend**](/reference/metrics/advertising/tiktok/tiktok-spend/tiktok-spend)                              | Total amount spent on TikTok advertising           |

| **Type**        | Currency                           |

## Example

Your activewear brand spent **\$2,400** on TikTok ads last week and drove **320 checkout starts**.

| Campaign          | Spend   | Checkouts | Cost/Checkout |
| ----------------- | ------- | --------- | ------------- |
| Summer Collection | \$1,200 | 200       | \$6.00        |
| Influencer Collab | \$800   | 96        | \$8.33        |
| Flash Sale        | \$400   | 24        | \$16.67       |

## How It Works

TikTok calculates this metric by dividing your total ad spend by the number of checkout initiations attributed to your ads. A lower cost per checkout indicates efficient bottom-of-funnel performance—your ads successfully move high-intent shoppers toward purchase at a reasonable cost.

## When to Use

| Scenario                          | Action                                                                 |
| --------------------------------- | ---------------------------------------------------------------------- |
| Cost rising while checkouts drop  | Test new creative angles or refine audience targeting                  |
| Lower cost than CPA               | Strong mid-funnel—investigate checkout abandonment for conversion gaps |
| Cost varies by campaign           | Reallocate budget toward campaigns with lower checkout costs           |
| Cost acceptable but purchases low | Focus on checkout experience and retargeting abandoners                |
