Understanding
Customer Churn

Churn is the silent killer of SaaS companies. Learn why customers leave and how to stop them.

THE BASICS

What is Customer Churn?

Churn is when customers stop using your product. It's the opposite of retention, and it's one of the most important metrics for any SaaS business.

The Basic Formula

How churn rate is calculated

Churn Rate = (Customers Lost / Total Customers at Start) × 100

Example: You started the month with 1000 customers and lost 50

(50 / 1000) × 100 = 5% monthly churn rate

Why Churn Matters More Than You Think

📉

Kills Growth

High churn means you're filling a leaky bucket. Every new customer you acquire just replaces one who left.

Example: If you have 10% monthly churn, you need to grow by 10% each month just to stay flat.

💸

Destroys Economics

If customers leave before you recoup acquisition costs, you're losing money on every sale.

Example: CAC = $500, Monthly MRR = $100, Churn after 3 months = You lost $200

⚠️

Signals PMF Issues

High churn often means you haven't achieved product-market fit. Customers aren't finding value.

Rule of thumb: Monthly churn above 5-7% for B2B SaaS indicates PMF problems

📊

Impacts Valuation

Investors value companies with low churn at 2-3x higher multiples than high-churn companies.

Impact: Reducing churn from 10% to 5% can increase company value by 50%+

The Two Types of Churn

🚪

Voluntary Churn

Customers actively choose to leave

Common Reasons:

  • Not getting value from the product
  • Found a better alternative
  • Product is too expensive
  • Poor customer support experience
  • Missing critical features

Good news: This is preventable with feedback! Exit surveys tell you exactly why people leave.

💳

Involuntary Churn

Customers don't mean to leave

Common Reasons:

  • Credit card expired
  • Payment failed
  • Billing address changed
  • Account fraud/security issues
  • Bank declined transaction

Easy fix: Automated email reminders + payment retry logic can recover 20-30% of this churn.

What's a "Good" Churn Rate?

B2B SaaS (Enterprise)
0.5-1%
Monthly churn
Annual contracts, high ACV
B2B SaaS (SMB)
3-5%
Monthly churn
Monthly contracts, mid ACV
B2C SaaS
5-7%
Monthly churn
Monthly subscriptions, low ACV

Rule of Thumb: If your monthly churn is above 7%, you have a serious retention problem that needs immediate attention.

The True Cost of Churn

Let's say you have 1000 customers paying $100/month with 5% monthly churn

Customers Lost/Month
50
5% of 1000
Monthly Revenue Lost
$5K
50 × $100
Annual Revenue Lost
$60K
$5K × 12 months

What if you reduced churn by just 2%?

Before (5% churn)
$60K lost/year
After (3% churn)
$36K lost/year

You just saved $24,000/year! 💰
