Ace

The ACE tool, which you're welcome to play with, will do this in a much more detailed way. It lets you break down these retention rates by the first six months. And it's letting you apply different churn rates to different cohorts. Like my month one retention rate is about 65%. But my long term one was 95%, which sort of makes sense intuitively that there's a group of people who start the subscription, start using it and then cancel it.
