1. What is a Retention Expense Calculator?

Definition: This calculator estimates the total cost of customer retention based on marketing costs, additional expenses, and number of retained customers.

Purpose: It helps businesses understand and budget for the costs associated with maintaining their customer base.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( RE \) — Retention expense (USD)
• \( M \) — Marketing cost per customer (USD)
• \( A \) — Additional retention costs (USD)
• \( N \) — Number of retained customers (dimensionless)

Explanation: The marketing and additional costs per customer are summed, then multiplied by the number of customers retained to get the total retention expense.
