The Cost-Per-Meeting (CPM) is a lead generation metric that calculates the cost of generating a meeting with a prospective client. To calculate CPM, divide the total cost of your lead generation activities by the number of meetings you generated. For example, if you spend $1,000 on lead generation efforts and generate 10 meetings, your CPM would be $100. This metric is useful for evaluating the effectiveness of your lead generation campaigns and determining how much you can afford to spend to generate a meeting.
