Know how much it costs to acquire one customer.
Quick answer: CAC Calculator
Divide acquisition spend by new customers to see what each customer cost to land.
Example: $48,000 marketing + $12,000 sales tools in a month, 540 new paying users → CAC ≈ $111 per customer.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
