Use Cases for This Calculator
Calculating Total Inventory Value
To calculate the total value of your inventory, enter the quantity and price of each item. The calculator will multiply the quantity by the price and sum up these values to give you the total inventory value.
Determining Profit Margin
To determine the profit margin on your inventory items, enter their cost price and selling price. The calculator will subtract the cost price from the selling price, divide the result by the selling price, and give you the profit margin percentage.
Calculating Turnover Rate
To find the turnover rate of your inventory, input the cost of goods sold and average inventory value. The calculator will divide the cost of goods sold by the average inventory value to provide you with the turnover rate.
Estimating Reorder Point
Estimate the reorder point by entering the lead time demand, safety stock, and average daily sales. The calculator will multiply the lead time demand by the safety stock, plus the average daily sales, to determine the reorder point.
Calculating Carrying Cost
To calculate the carrying cost of inventory, input the average inventory value and the carrying cost percentage. The calculator will multiply the average inventory value by the carrying cost percentage to give you the carrying cost.
Estimating Economic Order Quantity (EOQ)
Determine the Economic Order Quantity by entering the annual demand, ordering cost, and holding cost. The calculator will compute the square root of [(2 x Annual Demand x Ordering Cost) / Holding Cost] to provide you with the EOQ.
Calculating Days Sales of Inventory (DSI)
To calculate the Days Sales of Inventory, enter the average inventory value and the cost of goods sold. The calculator will divide the average inventory value by the cost of goods sold and then multiply the result by 365 to determine DSI.
Estimating Stock-to-Sales Ratio
Estimate the Stock-to-Sales Ratio by entering the average inventory value and the net sales. The calculator will divide the average inventory value by the net sales to provide you with the stock-to-sales ratio.
Calculating Inventory Shrinkage Rate
To determine the inventory shrinkage rate, input the value of lost inventory and the original inventory value. The calculator will subtract the lost inventory value from the original inventory value and divide the result by the original inventory value to give you the shrinkage rate.
Estimating Inventory Days Coverage
Estimate the Inventory Days Coverage by entering the average inventory value and the cost of goods sold. The calculator will divide the average inventory value by the cost of goods sold and then multiply the result by 365 to determine the inventory days coverage.
