Let’s say a coffee brand ended the last period with ₱40,000 in finished goods inventory, making the beginning finished goods inventory ₱40,000.

Now let’s say the COGM for the period is ₱70,000, and their COGS is ₱50,000.

Here’s how to calculate the finished goods inventory formula:

Finished Goods Inventory = ₱40,000 + ₱70,000 – ₱50,000

Finished Goods Inventory = ₱60,000

Thus, ₱60,000 worth of the finished inventory will be the next accounting period’s beginning finished goods inventory.
