CAC Calculator
Enter your total marketing spend and new customers acquired to instantly calculate your Customer Acquisition Cost.
How to Use This Calculator
CAC tells you exactly what it costs to bring in one new paying customer. Use it to benchmark channel efficiency and model payback periods.
Enter your total marketing spend
Include all spend for the period: paid ads, agency fees, tools, events, and any other acquisition-related costs. Use the same time window as your customer count.
Enter new customers acquired
The number of new paying customers who converted during the same period. Exclude renewals, upsells, and reactivations — only count net new customers.
Read your CAC
The result shows your average cost to acquire one customer. This is the foundation metric for calculating payback period and LTV:CAC ratio.
Compare against LTV
CAC is most meaningful when compared against Customer Lifetime Value. A healthy LTV:CAC ratio is typically 3:1 or higher for sustainable growth.
