How to Calculate Inventory Reorder Point

Calculating the inventory reorder point is essential for maintaining optimal stock levels. Follow these steps to determine the precise reorder point for each product in your inventory:

Step 1: Calculate Your Average Daily Usage

First, determine the average number of units sold or used per day. This can be calculated by dividing the total number of units used over a specific period by the number of days in that period:

Average Daily Usage = Total Units Used / Number of Days

Step 2: Determine Lead Time

Lead time is the average time it takes for an order to arrive. Calculate it as follows:

Lead Time = Average Number of Days for Delivery

Step 3: Calculate Safety Stock

Safety stock is the buffer inventory you keep to avoid stockouts. Use this formula:

Safety Stock = (Maximum Daily Usage * Maximum Lead Time) – (Average Daily Usage * Average Lead Time)

Step 4: Calculate Reorder Point

Finally, calculate the reorder point with this formula:

Reorder Point = (Average Daily Usage * Lead Time) + Safety Stock

Example Calculation

Let’s say:

  • Average Daily Usage = 20 units
  • Lead Time = 7 days
  • Safety Stock = 50 units

Reorder Point = (20 * 7) + 50
Reorder Point = 140 + 50
Reorder Point = 190 units

When your inventory level reaches 190 units, it’s time to reorder. This simple method helps you keep your stock at the right levels and avoid running out.
