What is CAC and why is it important
CAC is the price you pay for a user to buy something from you for the first time. It is not just the price of a click or impression. It is the price per purchase. You can have a thousand visits a day, but if no one buys, you do not earn.
If your CAC is higher than the profit per customer, you are working at a loss every day, emphasized the experts at Mafpels trading. It is like paying rent for a store in a shopping center where no one comes. Or comes, looks, and leaves empty-handed.
You launch an ad. Pay for clicks, hire a designer for a banner, a copywriter for texts, maybe even a targeting specialist or SEO specialist. All of these are expenses. Add them all up for a certain period. And then divide by the number of buyers you managed to attract during the same time.
Formula: CAC = total marketing expenses / number of new customers.
IMPORTANT! A customer is someone who has paid. Not just visited, not just left an e-mail, but paid money. Only such people need to be counted.
How to calculate CAC
Another trap is to calculate on average. Let's say you have advertising on social networks, search results, a blog, a newsletter and affiliate programs. Together they give a normal figure for CAC. But if you do not break it down by channels, you will not see that half of the budget is wasted. Perhaps the blog brought ten clients almost for free, and advertising on the social network ate up the entire budget without giving anything. Do separate analytics, advises Mafpels. This is the only way to understand what works and what it is time to get rid of.
Why it is important to calculate not "on average", but by advertising channels
