How to calculate customer acquisition cost with a customer acquisition cost calculator
Customer acquisition cost (CAC) is what you pay, on average, to win one new customer. You add up everything spent on marketing and sales in a period, then divide by the number of new customers that spend produced. If you spent $25,000 and gained 500 customers, your CAC is $50. It is one of the most important numbers in any growth model, because a business only compounds when a customer is worth more over their lifetime than they cost to acquire.
There is no single 'good' CAC β it only means something next to lifetime value (LTV). A healthy LTV:CAC ratio is often cited around 3:1, so lowering CAC or raising LTV both strengthen your economics. One of the fastest levers is conversion: App Store creative and ASO lower CAC by converting more of the exact same traffic into installs. That is exactly what Reverze does β rebuilding higher-converting screenshots so every marketing dollar buys more customers.
