Net Negative Churn

When the extra money existing customers spend through upgrades outweighs the money lost to cancellations, so revenue from your current base grows even with no new customers.

Net negative churn is a sign of a very healthy subscription business, because revenue compounds from customers you already have.

Upgrades add £1,200 this month while cancellations cost £700, so your existing customers grew revenue by £500 on their own.
