Churn rate: (75 ÷ 1,000) × 100 = 7.5%

The True Cost of Churn

Revenue Impact Calculator

Example: 10% Monthly Churn

Starting customers: 1,000
Monthly churn rate: 10%
Revenue per customer: $50/month

Month 1: 1,000 customers → $50,000 revenue
Month 2: 900 customers → $45,000 revenue (-$5,000)
Month 3: 810 customers → $40,500 revenue (-$4,500)
Month 4: 729 customers → $36,450 revenue (-$4,050)

Lost revenue in 4 months: $13,550
Annual projected loss: ~$180,000

Acquisition vs Retention Cost

Cost to Acquire New Customer (CAC):

  • Paid ads: $30-$100
  • Organic: $10-$30
  • Referral: $5-$15

Cost to Retain Existing Customer:

  • Email campaigns: $0.10-$1
  • Loyalty rewards: $2-$5
  • Personalized offers: $3-$8

The 5:1 Rule: It costs 5x more to acquire than retain

Lifetime Value Loss

Average Customer Lifetime Value (LTV):

- LTV: $1,200

With 10% Monthly Churn:
- Actual lifetime: 10 months
- Actual LTV: $500
- Lost value: $700 per customer

1,000 customers × $700 lost = $700,000 total impact

Churn Calculation Examples

Example 1: Monthly Churn

January 1: 5,000 customers
January 31: 4,650 customers
New customers acquired: 150
Customers lost: 500

Churn Calculation:
Lost customers: 5,000 + 150 - 4,650 = 500
Churn rate: (500 ÷ 5,000) × 100 = 10%

Example 2: Annual Churn

January 1, 2024: 10,000 customers
December 31, 2024: 6,500 customers
New customers acquired: 2,500
Customers lost: 6,000

Annual Churn:
Lost: 10,000 + 2,500 - 6,500 = 6,000
Churn rate: (6,000 ÷ 10,000) × 100 = 60%

Example 3: Cohort Analysis

January 2024 cohort:

Acquired: 500 customers
Still active after:
- Month 1: 450 (10% churn)
- Month 3: 380 (24% churn)
- Month 6: 310 (38% churn)
- Month 12: 225 (55% churn)

You have 0% net growth despite spending on acquisition

Common Churn Calculation Mistakes

Measuring too infrequently - Missed trends
Ignoring revenue churn - All customers aren't equal value
No segmentation - Different cohorts have different churn
Focusing only on churn - Retention rate is equally important
