Taiwan Numerical Powers Co Days Inventory Calculation

Days Inventory indicates the number of days of goods in sales that a company has in the inventory.

Taiwan Numerical Powers Co's Days Inventory for the fiscal year that ended in Dec. 2025 is calculated as

Days Inventory (A: Dec. 2025 )
=Average Total Inventories / Cost of Goods Sold*Days in Period
=( (Total Inventories (A: Dec. 2024 ) + Total Inventories (A: Dec. 2025 )) / count ) / Cost of Goods Sold (A: Dec. 2025 )*Days in Period
=( (142.448 + 102.467) / 2 ) / 337.884*365
=122.4575 / 337.884*365
=132.29

Taiwan Numerical Powers Co's Days Inventory for the quarter that ended in Mar. 2026 is calculated as:

Days Inventory (Q: Mar. 2026 )
=Average Total Inventories / Cost of Goods Sold*Days in Period
=( (Total Inventories (Q: Dec. 2025 ) + Total Inventories (Q: Mar. 2026 )) / count ) / Cost of Goods Sold (Q: Mar. 2026 )*Days in Period
=( (102.467 + 110.516) / 2 ) / 89.984*365 / 4
=106.4915 / 89.984*365 / 4
=107.99
