| --------------------------------------------------------------------------------------------------- | ---------------------------------------------------- |
| [**Meta Spend**](/reference/metrics/advertising/meta/meta-spend/meta-spend)                         | Total amount spent on Meta advertising               |
| [**Meta Contact Events**](/reference/metrics/advertising/meta/meta-conversions/meta-contact-events) | Number of contact submissions attributed to Meta ads |

## Example

Your home services business spent **\$2,400** on Meta ads and generated **80** contact requests.

| Campaign        | Spend   | Contacts | Cost per Contact |
| --------------- | ------- | -------- | ---------------- |
| Kitchen Remodel | \$1,200 | 30       | \$40.00          |
| Bathroom Reno   | \$800   | 35       | \$22.86          |
| General Inquiry | \$400   | 15       | \$26.67          |

***

## How It Works

Cost per Contact divides your total Meta ad spend by the number of contact events tracked via the Meta Pixel or Conversions API. Contact events typically fire when someone submits a contact form, requests a quote, or initiates a service inquiry.
