Lost in month: 75 customers

Churn rate: (75 ÷ 1,000) × 100 = 7.5%

```

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)

```

Break-Even Churn

You have 0% net growth despite spending on acquisition

```
