Monthly Churn.

Updated

Monthly churn is the default churn metric for one reason: it is the fastest signal a subscription business has. Annual churn tells you what happened a year ago. Monthly churn tells you whether the fix you shipped two weeks ago is working.

How Joy Subscriptions handles this

Joy Subscriptions, a build-to-order subscription app for Shopify, attacks monthly churn at the cancel click and at the failed charge, separately.

Churn cohorts show when subscribers leave rather than only how many, so the fix targets a cycle instead of the whole base.

Why monthly is the standard

  • Operational speed — most subscription billing cycles are monthly, so cancellations are naturally month-aligned.
  • Comparable benchmarks — almost every SaaS and subscription benchmark study quotes monthly figures.
  • Sensitive to interventions — a save-offer launch can show up in monthly churn within 30–60 days, while annual figures hide the change for a year.

The pitfalls of monthly churn

Monthly numbers swing on small samples. A subscription business with 500 active subscribers and 25 cancellations a month has a 5% monthly churn rate; one extra or one fewer cancellation moves the rate by 0.2 points. Three-month rolling averages smooth this noise out and are the more honest operating metric for small bases.

Seasonality also distorts monthly figures. Holiday signups churn faster than year-round ones. January cancellation spikes (New Year recommitments) and July dips (summer fatigue) are real. Year-over-year monthly comparisons help separate the trend from the season.

What to do with a monthly churn number

  1. Compare to last month and 3 months ago — directionality matters more than absolute level.
  2. Slice by signup cohort — month-1 customers churn faster than month-12 customers. Aggregate numbers hide this.
  3. Split voluntary from involuntary — different fixes, different ownership.
  4. Compare like seasons year-over-year — last December vs. this December, not December vs. last month.

Frequently asked questions

What is a good monthly churn rate?+
For Shopify subscription stores, under 5% monthly is excellent and 5–8% is healthy. For B2B SaaS, the target is 1–3% monthly. Consumer streaming and content subscriptions average 3–6% monthly. Compare against your category specifically — averages across categories are misleading.
Why does my monthly churn fluctuate so much?+
Small subscriber bases swing on small numbers. Seasonality also moves the rate (holidays, summer). Use a 3-month rolling average for operating reviews and compare like seasons year-over-year for trend analysis. Single-month numbers are too noisy to act on for most subscription stores.
How do I convert monthly churn to annual?+
Use 1 − (1 − monthly_churn)^12. A 5% monthly churn equals about 46% annual, not 60%. The naive 12x multiplication overstates the loss because the customer base shrinks each month.
Should I report monthly or annual churn?+
Report both, for different audiences. Monthly churn for operations and retention teams (it is sensitive enough to act on). Annual churn for finance, board reviews, and investor updates (it lines up with how those audiences model the business).
