    Customer Acquisition Cost (CAC) is the total cost to acquire one new customer. Calculate it: CAC = (Total Sales & Marketing Costs) ÷ (Number of New Customers Acquired). For example, if you spend $10,000 on marketing and acquire 100 customers, your CAC is $100. Healthy CAC to LTV ratio is 1:3 (customer lifetime value should be 3x CAC). Track CAC by channel to optimize spend. Reduce CAC through organic channels, referrals, and better targeting.
