Churn Rate & Retention: The Two SaaS Metrics That Predict Survival

Churn is the silent killer of SaaS businesses. You can outrun it with new sales for a while, but eventually the leaky bucket catches up. Here’s how to measure and benchmark it.

Customer Churn Formula

Churn Rate (%) = Customers Lost in Period ÷ Customers at Start × 100

Use our Churn Rate Calculator for monthly and annualized views.

Retention Rate Formula

Retention Rate (%) = (Customers at End − New Customers in Period) ÷ Customers at Start × 100

Run yours in our Customer Retention Rate Calculator.

2026 SaaS Churn Benchmarks (Monthly)

• SMB SaaS: 3–5% — anything >7% is critical
• Mid-market: 1–2%
• Enterprise: 0.5–1% (annual contracts)

Why Monthly Churn Compounds Brutally

• 2% monthly = 21.5% annual
• 5% monthly = 46% annual
• 10% monthly = 72% annual

Net Revenue Retention: The North Star

NRR > 100% means expansion outpaces churn — even with no new logos, revenue grows. Top SaaS companies report NRR of 115–130%.

The Three Levers to Reduce Churn

1. Onboarding. 60% of churn happens in the first 90 days.
2. Activation milestones. Define and instrument the “aha moment.”
3. Annual billing. Annual customers churn 50–70% less than monthly.

FAQs

Should I report logo churn or revenue churn? Both. Revenue churn matters for valuation; logo churn for product health.

Does pausing count as churn? Treat pauses as churn after 30 days unless the customer returns.
