Weighted Average cost of ending inventory (20) units is $ 193.
Explanation :-
While using the weighted average cost method, we 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. This weighted average figure is then used to assign a cost to both ending inventory and the COGS.
Calculation :-
Weighted Average Cost = Cost of goods available for sale / number of units available for sale
where,
Cost of goods available for sale = Value of beginning inventory + Value of net purchase
= (40 units * $9 per unit) + (80 units * $ 10 per unit)
= 360 + 800
=1160
Number of units available for sale = Units of beginning inventory + No. of units purchased
= 40 units + 80 units
= 120 units
Weighted Average Cost = 1160/120
= 9.66667
Value of Cost of Goods Sold = Units sold * Weighted average cost
= 100 units * 9.66667
= 966.667
Value of ending inventory = Closing inventory * Weighted average cost
= (120-100) units * 9.66667
= 20 units * 9.66667
= 193.33 or 193
