You can pour new customers into the top of your business all day, but if they leak out the bottom just as fast, you never grow. That leak is churn — the percentage of customers who cancel in a given month — and small numbers hide big damage.
The math and the shock
Churn = customers lost ÷ customers at the start of the period. Five percent monthly sounds tiny — but it means you replace your entire customer base in under two years just to stay flat. Growth has to outrun that before it does anything for you.
Where to plug it
- Fix onboarding — most churn is decided in the first week.
- Recover failed payments; a big share of “churn” is just expired cards.
- Attract the right customers in the first place — bad-fit signups churn hardest.
That last point ties straight back to your content: the posts that attract well-fit buyers reduce churn before it starts. Knowing which channels bring keepers versus quitters is a revenue-attribution question, and it’s one seenpaid helps you answer.
