Customer acquisition cost

$50.00

New customers

100

Each new customer costs $50.00 to acquire.

CAC, or customer acquisition cost, estimates how much it costs to acquire one new customer.

The basic formula is: CAC = total sales and marketing cost / new customers acquired. If you spent $5,000 on sales and marketing and acquired 100 new customers, your CAC is $50.00.

Use CAC to judge whether your growth cost is sustainable. For ecommerce, CAC should be compared with product margin, average order value, repeat purchase behavior, and customer lifetime value.

CAC is not the same as CPC. CPC shows how much each click costs. CAC shows how much each new customer costs after the funnel has done its work. A campaign can have a low CPC but a high CAC if traffic does not convert well.
