Practice As You Learn
There are 4 major things that you will most likely be asked to do:
1) Calculate cost of goods sold
2) Determine inventory and cost of goods sold using FIFO, LIFO, Average
3) Determine lower of cost or market (LCM)
4) Record inventory transactions using both methods: Periodic and Perpetual
1) Calculate cost of goods sold:
Memorize this formula:
Beginning Inventory
+ Purchases
= Available for sale
– Ending Inventory
= Cost of Goods Sold
To get an amount for purchases and inventory if it is not given to you – multiply the quantity x cost per unit
When doing the calculation, ignore everything other than purchases and finished goods inventory – beginning and ending
2) Determine the value of inventory and CGS using FIFO, LIFO, Average:
1st write the beginning inventory and purchases in date order:
Quantity x Cost per unit = Total Cost | |
Beginning | |
Purchases | |
Purchases | |
Purchases | |
Goods Available | $XXXX |
2nd Total the quantity column and total cost for the goods available column. You have total available. You will be given total units sold or total units in ending inventory. Determine the other one.
Quantity x Cost per unit = Total Cost
Beginning
Purchases
Purchases
Purchases
Goods Available
– Units Sold
= Units in inventory
3rd Use the quantity of units sold to determine the cost of goods sold based on the order sold.
FIFO: The first units are sold first
Start from the beginning and go down through the purchases until you have enough to total the units sold
LIFO: The last units are sold first
Start from the last purchase and go up through the purchases until you have enough to total the units sold
Average:
The average is the average of “goods available”
Total cost of goods available
Quantity of goods available = $Average cost
Then: quantity of units sold x $average cost = CGS
For all 3 methods:
Goods available
– CGS (income statement)
= Ending inventory value (balance sheet)
3) Determine lower of cost or market (LCM)
1st Set up the table as follows:
Item | Total Cost | Total Market | Total LCM |
2nd Put the given amounts in the cost and market column
3rd Compare the cost to the market and put the lowest in the LCM column
4th Total the cost column and total the LCM column
5th The lowest total – cost or LCM must be reported as the inventory value
If LCM is lower than cost, reduce inventory for the difference
CGS $XXX
Inventory $XXX
4) Record inventory transactions: Periodic and Perpetual
Periodic method: Only use the inventory account for the final adjustment
1) Put the beginning inventory amount in the “T” account
2) Record purchases to the “purchase account” and accounts payable/cash
3) Record the sales and receivable only for a sale (nothing for inventory)
You have not used the inventory account and it is showing the amount for beginning inventory instead of the amount on hand at the end.
4) Adjust the inventory account to the ending amount – use CGS also
5) Credit the purchases account for the amount in the account to make it be 0; use CGS for the debit
Perpetual method: Use the inventory account for every transaction
1) Put the beginning inventory amount in the “T” account
2) Record purchases in the inventory account and accounts payable/cash
3) Record sales/receivables and the cost of goods sold/inventory
Put the inventory amounts from the journal entries into the “T” account.
You have used the inventory account to report each movement and the inventory account shows a running balance of the cost of inventory on hand. It may be incorrect due to human errors.
4) Count what you have and make the inventory account be what you actually have. The other account used is cost of goods sold.

Answer to Practice Problem 1 – Calculate Cost of Goods Sold
Use the formula and ignore all other items on the list:
Beginning Inventory $ 420,000
+ Purchases $2,150,000
= Available for sale $2,570,000
– Ending Inventory $ 885,000
= Cost of Goods Sold $1,685,000
Practice Problem 2 – FIFO, LIFO, Average
The Company had the following transactions during the first quarter:
Units | Cost per unit | ||
January 1 | Beginning Balance | 900 | $11 |
January 15 | Purchased | 500 | $10 |
February 2 | Sold | 600 | |
February 5 | Purchased | 400 | $12 |
February 18 | Sold | 700 | |
March 15 | Purchased | 600 | $11 |
Determine the value of ending inventory and cost of goods sold for the quarter using the periodic method (CGS is determined at the end of the period, ignore dates sold)
A. FIFO
B. LIFO
C. Average Cost

Answer to Practice Problem 2 – FIFO, LIFO, Average
1st – line up the purchases in date order, get total cost, and subtract the total quantity sold to get ending inventory quantity:
Units | x Cost per unit | = Total Cost | ||
January 1 | Beginning Balance | 900 | $11 | $9,900 |
January 15 | Purchased | 500 | $10 | $5,000 |
February 5 | Purchased | 400 | $12 | $4,800 |
March 15 | Purchased | 600 | $11 | $6,600 |
Available | 2400 | $26,300 | ||
– Total Sold | (1,300) | ?? | ||
Ending Inventory | 1,100 | ?? |
Since the cost per unit is different, you must determine the total cost of the 1,100 units left in inventory using a chosen method.
Part of the total cost is CGS and part of the total cost is inventory.
FIFO (first in – first out):
Units purchased first are sold first. Work down until you have a total of 1,300 sold
Units | x Cost per | = Total Cost | ||
January 1 | Beginning | 900 | $11 | $9,900 |
January 15 | Purchased | 400 | $10 | $4,000 |
Total Sold | 1,300 | $13,900 CGS |
Notice that you do not take all 500 of the 1/15 purchase, you only take enough to get to the total sold of 1,300.
To get Ending Inventory:
Available $26,300
– CGS ($13,900)
= Ending Inventory $12,400
LIFO (last in – first out):
Units purchased last are sold first. Work up until you get to the total units sold of 1,300
Units | x Cost per | = Total Cost | ||
JAnuary 15 | Purchased | 300 | $10 | $3,000 |
February 5 | Purchased | 400 | $12 | $4,800 |
March 15 | Purchased | 600 | $11 | $6,600 |
1,300 | $14,400 CGS |
Notice that you do not take all 500 of the 1/15 purchase, you only take enough to get to the total sold of 1,300.
To get Ending Inventory:
Available $26,300
– CGS ($14,400)
= Ending Inventory $11,900
Weighted Average:
Inventory is valued at the average purchase cost.
Total available cost divided by total available units = average cost per unit
Units | x Cost per | = Total Cost | ||
January 1 | Beginning | 900 | $11 | $9,900 |
January 15 | Purchased | 500 | $10 | $5,000 |
February 5 | Purchased | 400 | $12 | $4,800 |
March 15 | Purchased | 600 | $11 | $6,600 |
Available | 2,400 | $26,300 |
Average cost = $26,300 / 2,400 = $10.96 (round to dollars & cents)
Average cost $10.96
x units sold 1,300
= CGS $14,248
Ending Inventory:
Available $26,300
– CGS ($14,248)
= Inventory $12,052
Practice Problem 3 – Lower of Cost or Market
Company XYZ has 3 items in inventory with a quantity and cost as follows:
Quantity | Cost | |
Item 1 | 220 | $3 |
Item 2 | 160 | $2 |
Item 3 | 175 | $2,50 |
After further analysis, the company determined that the market for Item 1 is $2.95, for item 2 is $2.20 and item 3 is $2
Determine if a write-down of inventory is required using lower of cost or market
Check Your Answer
Answer to Practice Problem 3 – Lower of Cost or Market
1st – Set up the table and calculate the total cost and the total market
Quantity | Cost | Total Cost | Market | Total Market | |
Item 1 | 220 | $3 | $660 | $2.95 | $649 |
Item 2 | 160 | $2 | $320 | $2.20 | $352 |
Item 3 | 175 | $2.50 | $437.50 | $2.00 | $350 |
$1,417.50 | $1,351 |
2nd – Compare total cost to total market
When total market is lower, the inventory cost must be reduced to the total market.
You cannot report inventory at more than you can expect to receive for it.
Total Cost $1,417.50
– Total Market ($1,351.00)
= Write-down? $ 66.50
Yes, because market is lower
Never increase inventory
Cost of Goods Sold $66.50
Inventory $66.50
Practice Problem 4 – Periodic & Perpetual
A company purchased inventory for a cost of $65,000 on June 1. The company returned goods with a cost of $6,000 on June 12. On June 14, goods with a cost of $21,000 were sold to the customer for $42,000. Inventory actually counted at the end of June totaled $48,000. Purchases and sales were for cash. Beginning inventory is $12,000. Make the appropriate journal entries for the transactions related to inventory using
1) the periodic method
2) the perpetual method.

Answer to Practice Problem 4 – Periodic & Perpetual
A company purchased inventory for a cost of $65,000 on June 1. The company returned goods with a cost of $6,000 on June 12. On June 14, goods with a cost of $21,000 were sold to the customer for $42,000. Inventory actually counted at the end of June totaled $48,000. Purchases and sales were for cash. Beginning inventory is $12,000. Make the appropriate journal entries for the transactions related to inventory.
1) Periodic Purchases $65,000 Cash $6,000 A/R $42,000 |
Periodic Adjusting Entry: Cost of Goods Sold $23,000 |
2) Perpetual Inventory $65,000 Cash $6,000 A/R $42,000 Cost of Goods Sold $21,000 |
Perpetual Adjusting Entry Cost of Goods Sold $2,000 |
If you are taught this without purchase returns, do the same thing, just leave the entry for purchase returns out and don’t put this account in the adjusting entry.Notice: The total cost of goods sold is the same for both methods. For periodic, you cannot determine the shrink
