Understanding Churn Rate

What is churn rate?

Churn rate (also called attrition rate) is the percentage of customers who stop using your product during a given time period. For SaaS businesses, it's one of the most critical metrics because it directly impacts revenue growth and company valuation.

How to calculate customer churn rate

The formula is simple:

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

For example, if you started the month with 500 customers and 20 cancelled, your monthly churn rate is (20 ÷ 500) × 100 = 4.0%.

What is net revenue churn?

Net revenue churn accounts for expansion revenue (upgrades) alongside lost revenue from cancellations. It's possible to have negative net revenue churn, which means your existing customers are generating more revenue through upgrades than you're losing to cancellations. This is the holy grail for SaaS businesses.

Net Revenue Churn = ((Lost MRR − Expansion MRR) ÷ Starting MRR) × 100

What is a good churn rate for SaaS?

Benchmarks vary by market and business model, but general guidelines for monthly churn:

  • Below 2% — Excellent. Best-in-class for B2B SaaS.
  • 2–5% — Good. Healthy for most SaaS businesses.
  • 5–8% — Average. Room for improvement.
  • Above 8% — High. Churn is likely the biggest drag on growth.

B2C SaaS typically has higher churn (5–7% monthly), while B2B enterprise SaaS often achieves below 1% monthly churn.
