Member Acquisition Cost (MAC) is the total monetary cost associated with recruiting a new member. To effectively maintain and/or grow an organization, it is necessary to assign an average monetary value to potential membership sales.

Calculate the # of new members as described in Retention Rate above.

The Total Recruitment cost would be available from your accountant.

Example:

At the end of 2017, 75 new members had joined and $28,875 was spent on new member recruitment.

$28875 ÷ 75 = $385

MEMBER ACQUISITION COST = $385
