1. What is Days Of Stock?

Days Of Stock (DOS) is a financial metric that calculates how many days a company's current inventory will last based on its average daily sales rate. It helps businesses manage inventory levels and optimize supply chain operations.

2. How Does the Calculator Work?

The calculator uses the Days Of Stock formula:

Where:

• \( Inventory \) — Current inventory level in units
• \( Daily\ Sales \) — Average daily sales in units per day

Explanation: The formula divides the total inventory by the average daily sales to determine how many days the current stock will last at the current sales rate.

3. Importance of DOS Calculation

Details: DOS calculation is crucial for inventory management, cash flow optimization, and preventing stockouts or overstocking. It helps businesses maintain optimal inventory levels and improve working capital efficiency.

4. Using the Calculator

Tips: Enter current inventory in units and average daily sales in units per day. Both values must be positive numbers greater than zero for accurate calculation.
