Inventory Analysis

This calculator helps you determine how much inventory you should hold, and when you should place inventory orders. The calculation attempts to keep your inventory level as efficient as possible, while maintaining adequate safety stock.

Over the WEEKS_OF_ANALYSIS weeks your average inventory needs are TARGET_AVERAGE_INVENTORY units.

Over the next WEEKS_OF_ANALYSIS weeks your average inventory needs are TARGET_AVERAGE_INVENTORY units. Your minimum inventory at any time during this period is projected at MINIMUM_INVENTORY units and your maximum inventory is MAXIMUM_INVENTORY units. This assumes an EXPECTED_ANNUAL_GROWTH annual growth rate with an initial demand for your product at CURRENT_DEMAND_PER_WEEK per week. **GRAPH**
