How to Calculate Cost Per Thousand Contacts

The formula is straightforward. If you know your total spend and how many contacts you reached, you can calculate both metrics in seconds.

Cost Per Thousand Contacts = Total Cost / Total Contacts × 1,000

Step by Step

Divide your total campaign cost by the number of contacts.
Multiply the result by 1,000 to get the cost per thousand contacts.

Example

If your campaign costs $500 and reaches 25,000 contacts:

$500 / 25,000 × 1,000 = $20.00

Your cost per thousand contacts is $20.00 — you paid $20 for every 1,000 contacts reached.
