Raw materials are the materials a company uses to create and finish products. When the product is completed, the raw materials are typically unrecognizable from their original form, such as oil used to create shampoo. MRO supplies or simply supplies or consumables are those materials that are consumed in the production processes but do not form a part of the finished goods or form a tiny part of the finished goods.

What are the 4 inventory cost methods?

The merchandise inventory figure used by accountants depends on the quantity of inventory items and the cost of the items. There are four accepted methods of costing the items: (1) specific identification; (2) first-in, first-out (FIFO); (3) last-in, first-out (LIFO); and (4) weighted-average.

Flour is the raw material for a company that produces bread or pizza. Similarly, metal parts and ingots are the raw materials bought by a company that manufactures cars, and crude oil is the raw material for an oil refinery.

Examples include the wood to make a base ball bat and the steel to make a car.

For example, there could be several indirect materials consumed during the production process that do not cost a lot and are typically purchased by the box in high volumes. As your orders increase, you may order a ton of extra materials, assuming that the more safety stock you have, the better. Recorded inventory might not reflect actual inventory, and without regular physical inventory counts this could lead to discrepancies. The difference between the cost of an inventory calculated under the FIFO and LIFO methods is called the LIFO reserve. This reserve is essentially the amount by which an entity’s taxable income has been deferred by using the LIFO method.

In our example, this could be an enormous vat of jam that’s still cooking, waiting to be finalized, put into jars, and sealed.
