Churn Calculator
Calculate churn and retention from customer losses.
📖 What it is
Understanding churn is essential for any SaaS startup, as it directly impacts revenue and growth. The Churn Calculator helps you quantify customer losses, allowing you to track retention and identify issues in your service delivery.
To use the Churn Calculator, input your starting customer base and the number of customers lost over a specified time frame. The output will show your churn rate as a percentage, alongside the retention rate, giving you clear insights into your customer dynamics.
It's important to note that the calculator assumes you are considering a specific period and that reactivations of previously lost customers are not included in the losses counted. Ensure that your input data is accurate to avoid misleading results.
How to use
- Determine the number of customers at the start of the period.
- Count the number of customers lost during the same period.
- Apply the formula to find your churn rate.
- Subtract the churn rate from 100 to get your retention rate.
- Use these rates to assess your customer retention strategies.
📐 Formulas
- Churn Rate—Churn Rate = (Lost Customers / Starting Customers) × 100
- Retention Rate—Retention Rate = 100 - Churn Rate
💡 Example
If you start with 1000 customers and lose 80 during the month:
1. Calculate churn: Churn Rate = (80 / 1000) × 100 = 8%.
2. Calculate retention: Retention Rate = 100 - 8 = 92%.
Real-life examples
Startup A
Started with 500 customers, lost 50 in a month. Churn Rate = (50 / 500) × 100 = 10%.
Company B
Had 2000 customers, lost 100 in a month. Churn Rate = (100 / 2000) × 100 = 5%.
Scenario comparison
- High Churn—Churn Rate over 10% indicates potential issues in service or customer satisfaction.
- Moderate Churn—Churn Rate between 5% and 10% shows room for improvement in customer engagement.
- Low Churn—Churn Rate below 5% suggests effective customer retention strategies are in place.
