Involuntary Churn

Also known as: Passive churn, Payment churn

Involuntary churn is subscription cancellation caused by a failed payment rather than a customer decision — typically an expired, blocked, or insufficient-funds card at renewal — which means the subscriber is lost while still wanting the product.

These are the cheapest subscribers a business will ever keep, because no persuasion is involved: they did not choose to leave, and nothing about the product needs to change. All that is required is a working card. Left alone, though, the cancellation looks identical to any other on a dashboard, which is why programs that do not measure the two kinds separately tend to blame the product for a billing failure.

For a sense of scale: across Recurly's network of subscription businesses, average monthly churn ran at 3.60 percent in July 2026, split 2.34 percent voluntary and 1.25 percent involuntary — putting involuntary churn at roughly a third of all churn there. Treat that as one billing platform's mix across many industries rather than a benchmark for any one store; the actual figure varies widely by market, card mix, and price point, and your own dashboard is the only number that matters.

The fix is dunning: automatic retries on a schedule that reflects why cards fail, paired with an email prompting the customer to update their payment method. Curobi runs failed-payment recovery with smart retries and recovery emails on the Pro plan.

Related terms

  • Voluntary Churn — Voluntary churn is subscription cancellation caused by a customer decision — they click cancel — as opposed to a failed payment, and it is usually a response to price, to product piling up between deliveries, or to the box becoming repetitive.
  • Churn — Churn is the rate at which subscribers cancel or lapse over a given period — the share of recurring customers a business loses — and it is the single most important number in a subscription business because retained revenue compounds while churned revenue must be re-acquired.
  • Dunning — Dunning is the automated process of recovering a failed subscription payment — retrying the declined charge on a schedule and prompting the customer to update their payment method — so a recoverable card failure doesn't silently cancel the subscriber.
  • Smart Retries — Smart retries are the scheduled re-attempts a subscription system makes on a failed recurring charge, timed and spaced deliberately rather than fired immediately, so that the retry lands when the underlying reason for the failure is most likely to have resolved.
