Churn

Churn is the share of customers you lose over a period. If 100 people paid for your membership on the first of the month and 5 of them cancelled before the end, your monthly churn is 5%. It is the leak in the bucket: however much you pour in at the top, churn decides how much stays.

The word comes from subscriptions, but it applies to anything people buy more than once. A coffee roaster loses customers who quietly switch brands. A creator with a paid community loses members who stop finding it useful. A skincare brand sees its repeat buyers fade after the second order. In every case, the question is the same: of the people who were customers yesterday, how many still are today?

What is churn?

Churn, also called attrition, is the percentage of customers at the start of a period who are no longer customers at the end of it. For a subscription, the moment of churn is clear: a cancellation, or a failed payment that is never recovered. For repeat purchases, you define it: a customer who has not ordered for a set window, usually two or three times the normal gap between orders, counts as churned.

Two flavors matter. Customer churn counts people. Revenue churn counts money, and it can differ: losing one $200-a-month client and keeping nine $10-a-month ones is 10% customer churn but 69% revenue churn. Sellers with several price tiers should track both.

Churn is the opposite of retention. A 5% monthly churn is a 95% monthly retention. And it is one of the three ingredients of customer lifetime value: the lower the churn, the longer the lifespan, the more a customer is worth.

What churn is not: a refund. A refund is one order reversed, and a customer who was refunded may or may not churn. It is also not a low conversion rate; churn only concerns people who had already bought.

Why it matters

Churn compounds, quietly. A membership at $15 a month with 200 members and 8% monthly churn loses 16 members a month. To grow at all, you need to sign more than 16 new members every month before growth even starts. At 4% churn, you need 8. The second community grows twice as fast with the same marketing.

Over a year the gap is larger than it looks. At 8% monthly churn, a member stays about 12.5 months on average and is worth $188. At 4%, they stay 25 months and are worth $375. Every new member is worth twice as much, so every dollar spent on getting members works twice as hard.

For a product brand, the same logic applies to repeat buyers. A candle brand whose customers buy 2.5 times before disappearing has a very different economics from one whose customers buy 5 times. The first can spend about half as much to acquire a customer as the second, and it will feel that ceiling in every ad campaign.

How to calculate it

• Pick a period. Monthly for subscriptions and memberships; quarterly or yearly for products bought a few times a year.
• Count the customers you had at the start of the period. Do not include those acquired during the period.
• Count how many of those starting customers were gone by the end: cancelled, unrecovered failed payment, or past your inactivity window for repeat purchases.
• Divide lost customers by starting customers and multiply by 100. Example: 340 members on 1 March, 24 cancelled by 31 March, churn is 24 / 340 × 100 = 7.1%.
• For revenue churn, do the same with monthly revenue: revenue lost from departed customers divided by revenue at the start.
• Convert between periods when you need to. Monthly churn of 5% is not 60% a year; it is 1 − (0.95)^12, about 46%, because the base shrinks each month.
• Track churn by cohort. Customers who joined in January and customers who joined in June may churn very differently, and the difference tells you whether you are getting better.

Benchmarks and examples

• Paid communities and memberships run by creators: 5% to 10% monthly churn is common, with the best under 4%. Most of it happens in the first two months.
• Consumable subscriptions (coffee, snacks, skincare): 6% to 12% monthly. Boxes with a strong ritual (a monthly coffee with a story about the farm) sit at the low end.
• Software and tools sold to small businesses: 3% to 7% monthly.
• Repeat purchase brands, measured yearly: 40% to 70% of first-time buyers never order again. A brand that keeps 40% of its customers into a second year is doing well.
• Courses with a follow-up program: 75% to 90% of buyers do not take the next step, which is expected rather than alarming.

Example: a creator launches a $12-a-month community with 150 founding members. Month one, 20 leave (13%). Month two, 12 of the remaining 130 (9%). Month three, 6 of 118 (5%). By month six churn settles around 4%. The early spike was people who joined on enthusiasm and left when they saw what the community actually was. That is normal; what matters is where it settles.

Common mistakes

• Including new customers in the denominator. If you sign 50 people during the month, they cannot churn yet, and counting them makes churn look better than it is.
• Measuring only customer churn when your customers pay different amounts. Losing your best clients hides behind a flat average.
• Confusing a failed payment with a decision. Expired cards cause a large share of subscription churn; a reminder recovers many of them.
• Treating churn as a single number instead of asking when it happens. Churn in week one is a promise problem. Churn in month eight is a value problem.
• Never asking why. A one-question cancellation survey tells you more than a month of analysis.

How to improve it

• Deliver the first value fast. The member who gets something useful in the first 48 hours stays. A welcome email with the three best resources, a first shipment that arrives early, a quick win in lesson one.
• Set expectations before the sale. Say what the community is and is not, how often the box ships, what the course covers. Churn from disappointment is the most avoidable kind.
• Remind people what they are getting. A monthly recap of what shipped, what was posted, what they used. People cancel what they forget.
• Offer a pause instead of a cancel. A one-month or two-month pause keeps the relationship alive for a customer who is broke this month or travelling.
• Recover failed payments. A card update email on day one, a second on day three, a friendly pause rather than an abrupt cut.
• Follow up between orders. For repeat products, email marketing timed to when the product runs out brings people back before they drift to a competitor.
• Listen to the leavers. Ask one question at cancellation and read every answer for a month. The top reason is usually fixable.

In Roctify

For repeat-purchase brands, Roctify keeps every order from every channel on one customer record, so you can see who ordered twice, who has gone quiet and how long it has been since their last order. Reports and exports on the Pro plan let you build a simple cohort view: customers acquired in a month, and how many ordered again.

Email marketing on the Creator plan and up covers the follow-up that reduces churn: a welcome series, a reorder reminder, a message to customers who have not ordered in 90 days. Memberships and subscriptions are on the roadmap; today, churn in Roctify is about repeat buyers rather than recurring billing.

FAQ

What is a good monthly churn rate?

For a creator-run membership or a consumable subscription, under 5% a month is good and under 3% is excellent. Above 8% for several months in a row means the product or the promise needs work before you spend more on acquisition.

How is churn different from a refund rate?

A refund reverses one order; churn is a customer who stops buying. A customer can get one order refunded and still stay. Refund rate is a measure of a single transaction, churn is a measure of the relationship.

When should I count a repeat buyer as churned?

Set the window from your own data. Look at the typical gap between two orders, then take two to three times that gap. If customers usually reorder every 45 days, someone who has not ordered in 120 days is churned. Adjust the window per product if the gaps differ a lot.
