Churn Rate (Customer Loss Rate)
How fast you’re losing customers out the back door, even as marketing brings new ones in the front.
…Reducing churn rate by even a few points has a bigger impact on revenue than most acquisition campaigns.…
What it means
Churn rate is the percentage of subscribers or customers who cancel or discontinue service within a given timeframe, usually measured monthly or annually.
Because losing customers offsets new ones, high churn can make a business feel like it’s treading water even while marketing hits its acquisition targets.
Undermines acquisition gains
New customers don’t grow the business if existing ones are leaving just as fast.
A leading indicator of satisfaction
Rising churn often signals product, pricing, or service problems before reviews do.
Directly shapes lifetime value
Lower churn means customers stick around longer, which raises LTV without any extra ad spend.
DNA's Take: We look at churn alongside acquisition metrics for every subscription or membership client, because retention is often the cheapest growth lever available.
