🎯 Customer Acquisition Cost (CAC) Calculator
CAC is the price tag on growth: everything you spend to win customers in a month, divided by the customers won. Once you know it, ads stop being a gamble and become arithmetic.
Cost per new customer
$100
Total acquisition spend
$1,500
Each new customer costs you $100. If a customer's lifetime profit is not at least 3 times that ($300), fix the offer or the funnel before buying more traffic; check it with the LTV calculator next.
Estimates for planning, not financial advice. Your real numbers will vary; that is exactly why you track them.
Good questions about this math
What is a good CAC?
There is no universal number; there is only CAC compared to what a customer is worth. The classic health line is a lifetime value at least 3 times CAC. A $100 CAC is great for a $2,000 service and fatal for a $40 product.
Do I count my own time?
Yes, price your selling hours at what they are worth (your hourly rate calculator result works). Free marketing that eats 20 hours a week is not free; counting it keeps you honest about which channel actually wins.
