Enter your subscriber numbers. Customer churn, revenue churn, annual churn, and average customer lifetime — calculated instantly.
Example: 250 customers at month start, 8 lost → 8 ÷ 250 × 100 = 3.2% monthly churn rate. This is the most common SaaS churn metric.
Example: $40K MRR at start, $1,200 lost from churned customers → $1,200 ÷ $40,000 × 100 = 3.0% revenue churn. Revenue churn can be higher or lower than customer churn depending on which customers leave.
Monthly churn compounds. A 3% monthly churn doesn't mean 36% annual — it means (1 − 0.03)¹² = 69.4% retention, or 30.6% annual churn. The compounding effect is significant and often misunderstood.
Example: 3% monthly churn → 1 ÷ 0.03 = 33.3 months (~2.8 years). This feeds directly into LTV: LTV = ARPU × average lifetime. Lower churn = longer lifetime = higher LTV.
Below 2% is strong. Below 3% monthly churn means you retain ~69% of customers over a year. At 3% monthly churn, average customer lifetime is ~33 months. This is the benchmark most investors use for seed/Series A stage.
At 5% monthly churn you lose ~54% of customers in a year. This is survivable if acquisition is cheap, but it means your growth engine must work twice as hard. Investigate why customers are leaving — product issues, pricing misalignment, or competitive pressure.
Above 7% monthly churn means you're losing the majority of your customer base every year. At 8% monthly, only ~39% of customers survive 12 months. Growth becomes a treadmill — you're acquiring just to replace what's leaving. Fix retention before investing in acquisition.
Customer churn measures how many people left. Revenue churn measures how much revenue walked out. A business losing high-value customers (high ARPU, long tenure) has worse revenue churn than customer churn. Conversely, losing low-value customers has minimal revenue impact. Track both — revenue churn is the one that actually threatens your runway.
