Monthly churn compounds. A box at 8% churn does not lose 8% once. It loses 8% every single month. Over 24 months that erases most of a subscriber base even with strong acquisition. This simulator shows the movie, not just the snapshot.
Most founders focus on acquiring more subscribers. But reducing churn by 3% often adds more revenue than doubling acquisition spend. The scenario comparison above shows the exact dollar difference for your numbers.
