Negative Churn

With ordinary churn, new sales first have to fill a leaking bucket before they add anything. With negative churn, each new customer lands on a base that already grows by itself, so growth compounds.

It also changes how a quiet quarter feels. If sales slows, revenue can still rise because existing customers are buying more. That gives a small team room to invest in the product instead of chasing short-term deals.

It is a sign that pricing and product are aligned: customers who succeed buy more. It is not a sign that cancellations can be ignored. Large losses can cancel out expansion quickly.

• Check that pricing grows with the value a customer gets, through seats, usage or volume. A flat fee makes negative churn very hard.
• Reduce cancellations and downgrades first. Expansion cannot outrun a large leak.
• Build the next step into the product, so growing accounts reach a higher tier on their own.
• Measure it by net revenue retention. A reading above 100 per cent means negative churn is happening.
• Split the figure by cohort, so one very large account does not hide a weak base.

Normal churn means a business loses revenue from customers it already has. Negative churn is the reverse: in a given month, what existing customers add outweighs what leaves. The measure is a revenue one, which is why it is also called negative revenue churn.

Take a business with £100,000 of monthly recurring revenue at the start of the month. Cancellations cost £3,000 and downgrades cost £2,000. Existing customers add £8,000 through extra seats and a higher tier. Net revenue churn is the £5,000 lost minus the £8,000 gained, divided by £100,000, which is minus 3 per cent. Existing customers alone grew revenue by 3 per cent.

• Confusing it with low churn. A business can lose many small customers and still show negative revenue churn if a few expand a lot.
• Treating it as a reason to stop selling. It is a bonus on top of acquisition.
• Celebrating one month. Look at the trend over several periods.
