1. What is a Retention Rate Calculator?

Definition: This calculator measures the percentage of customers a business retains over a specific period.

Purpose: It helps businesses assess customer loyalty and the effectiveness of retention strategies.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( RR \) — Retention rate (%)
• \( E \) — Customers at end of period
• \( N \) — New customers acquired
• \( S \) — Customers at start of period

Explanation: The formula calculates what percentage of original customers remained after accounting for new acquisitions.

3. Importance of Retention Rate

Details: Customer retention is crucial for sustainable growth, as retaining existing customers is typically more cost-effective than acquiring new ones.

4. Using the Calculator

Tips: Enter the number of customers at the start and end of the period, plus any new customers acquired during that time.

A: Yes, if you retain all original customers and gain new ones without losing any, the rate can exceed 100%.

Q3: What time period should I use?
A: Common periods are monthly, quarterly, or annually. Use whatever matches your business cycle.

Q4: How does this differ from churn rate?
