What are the main reasons of increasing COGS?

Increasing Cost of Goods Sold (COGS) can primarily result from rising raw material prices due to inflation or supply chain disruptions. Additionally, higher labor costs, increased production expenses, and inefficiencies in manufacturing processes can contribute to elevated COGS. Changes in product mix, such as a shift towards more expensive items, can also drive up COGS. Lastly, fluctuations in currency exchange rates may affect the cost of imported goods, further impacting COGS.
