Customer Acquisition Cost (CAC) Calculator
Estimate CAC from spend and acquired customers.
About This Calculator
CAC is one of the two most important metrics in any subscription or recurring-revenue business. It represents the average cost to acquire one new customer across all marketing and sales channels. Sustainable businesses maintain a healthy LTV:CAC ratio — typically 3:1 or higher.
Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.
CAC = total marketing spend ÷ new customers; cost per 1,000 = CAC × 1,000
