CAC is compared to the customer’s lifetime value (LTV). The only way to know whether you are getting customers profitably or at a loss is to calculate the LTV to CAC ratio.

Here’s how you can view the ratio (based on the article by Corporate Finance Institute).

1 : 1 or less The business is working at a loss, you need to make changes as soon as possible.
2 : 1 Customers bring two times more money than it costs to acquire them.
3 : 1 This is the optimal ratio to hit. It means the business model is profitable.
4 : 1 The business is very lucrative: acquiring customers is cheap, and they bring great value to the company.

What does customer acquisition cost mean

Customer Acquisition Cost (CAC) helps a company put a figure on the amount of money spent to acquire a new client in a given timeframe.

To evaluate CAC for your organization, you need to divide the total cost of acquiring a new client, including both advertising and production, by the total number of new purchasers attracted.
(Sales Cost + Ads Cost)
Total Number of New Clients
In email marketing, CAC shows the average cost to acquire a new customer with email campaigns and tactics, including multiple expenses like attracting, engaging, and turning website visitors and social media leads to paying buyers.
