Calculate the average cost to acquire one new customer across all marketing and sales efforts.
CAC = (Marketing Spend + Sales Spend + Other Costs) ÷ New Customers Acquired
The Customer Acquisition Cost (CAC) Calculator tallies up marketing and sales expenses to find the true cost of gaining one new paying customer.
Add your total marketing spend, sales team costs, and any overhead, then divide by the number of new customers acquired.
CAC is a critical metric for SaaS and subscription businesses. When compared against Lifetime Value (LTV), it tells investors and founders if the business model is sustainable.
