Key takeaways
Subscription churn is the rate customers cancel or lapse over a set period – it's a clear signal of whether your recurring revenue is actually growing or just replacing what walked out the door.
The simplest formula to calculate subscription churn: churn rate = (customers lost ÷ customers at start of period) × 100.
Airwallex Subscription Management tracks monthly recurring revenue, active subscriptions, churn and overdue payments from one dashboard, and includes built-in retry logic and reminders to help recover failed payments and reduce involuntary churn.
Subscription churn is the percentage of customers who cancel, or whose payments fail, within a given period. It's the clearest sign of whether your recurring revenue is actually growing, or just replacing what walked out the door.
Data from 2026 has found that Australians now spend an estimated A$26.5 billion a year on subscriptions, with 78% of adults paying for at least one service and holding an average of two subscriptions each¹. At that scale, even a small rise in churn can erode revenue you've already booked.
What is subscription churn?
Subscription churn is the rate at which customers cancel or lapse out of a recurring billing cycle over a set period, usually a month or a year. Track it and you'll know whether your subscriber base – and the recurring revenue attached to it – is growing, shrinking or just treading water.
For Australian subscription businesses, churn matters because recurring revenue is only as reliable as your ability to keep the customers generating it. With Australians juggling an average of two paid subscriptions each, the businesses that retain customers are the ones growing.
What causes subscription churn?
Subscription churn splits into two categories: customers who choose to leave (voluntary churn), and customers who lose access because a payment failed (involuntary churn).
Voluntary churn | Involuntary churn |
|---|---|
Poor onboarding or unrealised product value | Expired or declined cards |
A better-priced or better-fit competitor | Insufficient funds at renewal |
Perceived lack of value for the price | Bank fraud flags or authorisation failures |
Involuntary churn can be easier to address than voluntary churn because some payment failures are temporary or fixable, such as insufficient funds or an expired card.
How do you calculate subscription churn rate?
There's more than one way to calculate churn, but the simplest and most common is customer churn rate: divide the number of customers you lost in a period by the number you started with, then multiply by 100.
Churn rate = (customers lost ÷ customers at start of period) × 100
Say your Australian SaaS business starts the month with 500 customers and loses 20 by the end of it. Divide 20 by 500, multiply by 100, and your monthly churn rate is 4%.
That figure works well when your subscribers pay similar amounts, but it treats a A$19-a-month plan the same as a A$1,900 enterprise contract. If your business runs SaaS payment processing across multiple plans or currencies, calculate churn per plan or per currency to avoid a skewed average – then pair it with MRR churn (below) to see the revenue impact.
How to calculate MRR churn
Net MRR churn measures the change in monthly recurring revenue from existing customers after cancellations, downgrades, upgrades and reactivations are accounted for.
Net MRR churn rate = [(MRR lost to cancellations and downgrades − MRR gained from expansion and reactivation) ÷ MRR at start of period] × 100
If your business starts the month with A$200,000 in MRR, loses A$10,000 to downgrades and cancellations, and gains A$15,000 from existing customers upgrading, its net MRR churn rate is −2.5%, assuming no reactivation revenue. A negative result means expansion revenue is outpacing the revenue lost to churn.
What's a good churn rate for a subscription business?
There is no single “good” churn rate. However, Recurly’s² 2026 industry table reports a median annual churn of 3.22% for SaaS, 3.44% for Business & Professional Services and 4.25% for Ecommerce.
As a general rule: below 2% annual churn is strong performance; the 2–4% range is where most well-run subscription businesses sit; and anything above 5% is worth investigating regardless of industry.
Benchmarks vary for a few reasons:
Contract length. Annual contracts churn less often than month-to-month plans, but a lost annual customer costs more.
Price point. Recurly reports lower involuntary churn in higher average-revenue-per-customer cohorts, falling from 1.30% in its $10–25/month tier to 0.18% above $250/month. Note these are global figures and not Australia-specific.
Business model. B2B subscriptions typically churn less than B2C, thanks to longer contracts and higher switching costs.
How do you reduce subscription churn?
Reducing voluntary churn
Voluntary churn is a customer experience and product problem, not a billing one. The fixes sit in your CX and product toolkit:
Fix onboarding first. Poor early-stage engagement is the single biggest driver of voluntary cancellations – help customers reach value in their first weeks, not their first year.
Offer a pause, not just a cancellation. A large share of consumers prefer pausing over cancelling outright, and most paused subscribers return within months.
Run save offers and proactive outreach at renewal, not just after a cancellation request.
Reprice with usage-based billing where it fits, so customers pay for what they use rather than churning over a flat fee they've outgrown or underused.
Reducing involuntary churn
Involuntary churn is a payments and technology problem, not a customer service one – which makes it the more fixable of the two:
Run dunning sequences that combine retries with direct customer outreach, rather than a single silent retry.
Use automatic card updater services to catch expired or reissued cards before renewal.
Apply smart retry logic that times attempts around when payments are more likely to be approved, instead of retrying on a fixed schedule.
Send proactive expiry reminders and support multiple payment methods, so a single declined card doesn't end the relationship.
Build in short grace periods before suspending access, giving customers time to fix a failed payment without losing the subscription outright.
Businesses that also take one-off payments – through eCommerce payment processing, for example – can apply the same retry and recovery logic across both subscription and one-time transactions.
What investors typically look at
Investors may review net revenue retention (NRR) or net revenue churn alongside gross customer churn. Net measures include expansion revenue, while gross churn focuses on losses; present the metric definitions and measurement period clearly rather than assuming one metric always carries more weight.

Frequently asked questions
What is the difference between churn and retention?
Churn measures the percentage of customers or revenue you lose over a period; retention measures the percentage you keep. A 95% retention rate is the same as a 5% churn rate, but retention is usually the more useful number to report to stakeholders, since it frames the story around what's working.
How can I reduce my subscription churn?
Split churn into voluntary and involuntary, then address each separately. Voluntary churn may respond to better onboarding, proactive outreach and pause options; involuntary churn may respond to retry logic, dunning sequences and card updater services. Tackling involuntary churn can be a fast win, but prioritise it based on your payment-failure data and customer feedback.
What does a 20% churn rate mean?
A 20% churn rate means one in five customers cancelled or lapsed during the measured period. If that period is a year, it is well above the 2–5% directional annual ranges in Recurly’s global network data; if it is a month, it is substantially more severe. Investigate the product, pricing and payment-recovery drivers.
Is a higher or lower churn rate better?
Lower is always better – churn is a loss metric, not a growth one. A lower churn rate means you're keeping more of the customers and revenue you've already won, which reduces how much new business you need just to stay flat.
What is the difference between gross and net revenue churn?
Gross revenue churn counts only the revenue lost to cancellations and downgrades. Net revenue churn can be negative when expansion revenue outpaces revenue lost to cancellations and downgrades. NRR is a related retention metric that reports existing-customer revenue as a percentage of starting revenue; define both metrics clearly when reporting them.
