<Tip>
  TikTok Cost per Lead (CPL) measures the average spend required to generate one lead from your TikTok ads.

| ----------------------------------------------------------------------------------------- | ---------------------------------------------- |
| [**TikTok Ad Spend**](/reference/metrics/advertising/tiktok/tiktok-spend/tiktok-spend)    | Total amount spent on TikTok advertising       |
| [**TikTok Leads**](/reference/metrics/advertising/tiktok/tiktok-conversions/tiktok-leads) | Number of lead events attributed to TikTok ads |

| **Type**        | Currency                      |

## Example

A B2B company spent **\$4,500** on TikTok lead gen ads in March and captured **150 leads**.

| Month    | Ad Spend | Leads | Cost per Lead |
| -------- | -------- | ----- | ------------- |
| January  | \$3,200  | 80    | \$40.00       |
| February | \$3,800  | 95    | \$40.00       |
| March    | \$4,500  | 150   | \$30.00       |

March's CPL of **\$30.00** shows a 25% improvement from better targeting.

## How It Works

TikTok tracks lead events when users complete form submissions or sign-ups attributed to your ads. CPL divides total spend by lead events to show average acquisition cost.
