1. What is a Parts Department Fill Rate Calculator?

Definition: This calculator determines the fill rate percentage for a parts department by comparing fulfilled orders to total orders.

Purpose: It helps parts managers and inventory specialists measure service effectiveness and customer satisfaction.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( FR \) — Fill rate percentage
• \( O_f \) — Orders fulfilled (number of orders)
• \( O_t \) — Total orders (number of orders)

Explanation: The fulfilled orders are divided by total orders to get a ratio, then multiplied by 100 to convert to percentage.
