When using the weighted average method, divide the cost of goods available for sale by the number of units available for sale, which yields the weighted-average cost per unit. In this calculation, the cost of goods available for sale is the sum of beginning inventory and net purchases.

In **accounting**, the **Weighted Average** Cost (WAC) **method** of **inventory** valuation uses a **weighted average** to determine the amount that goes into COGS. The **weighted average** cost **method** divides the cost of goods available for sale by the number of units available for sale.

Secondly, how do you calculate gross profit from a perpetual inventory system? **Gross profit method**

- Add together the cost of beginning inventory and the cost of purchases during the period to arrive at the cost of goods available for sale.
- Multiply (1 – expected gross profit %) by sales during the period to arrive at the estimated cost of goods sold.

how do I calculate a weighted average?

The basic **formula** for a **weighted average** where the weights add up to 1 is x1(w1) + x2(w2) + x3(w3), and so on, where x is each number in your set and w is the corresponding **weighting** factor. To find your **weighted average**, simply multiply each number by its weight factor and then sum the resulting numbers up.

Is FIFO or LIFO better?
