Landed Material Cost & Consumption Formula

Consumed Cost = Quantity Consumed × [(Purchase Total + Inbound Freight) ÷ Purchase Quantity]
  • Landed Cost: Purchase price plus inbound transportation, handling, and tariffs per unit.
  • Accounting Separation: Unconsumed raw material remains on the balance sheet as an inventory asset and is not an expense of current production.

Step-by-Step Worked Example

Scenario: Purchasing 2,000 lbs of steel bar stock and consuming 1,200 lbs

Calculation Steps:

  1. Total Landed Cost = $9,000 + $500 = $9,500
  2. Landed Cost Per Pound = $9,500 / 2,000 = $4.75 / lb
  3. Consumed Material Cost = 1,200 lbs × $4.75 = $5,700
  4. Remaining Inventory = 800 lbs × $4.75 = $3,800
Result: Production material expense is $5,700. The remaining 800 lbs ($3,800) stays in raw materials inventory.

How to Use This Calculator

  1. 1Enter purchased material volume and invoice unit price.
  2. 2Add freight, customs, and delivery handling charges.
  3. 3Specify the quantity of material physically consumed in the production run.

Assumptions & Limitations

  • Assumes weighted-average or FIFO landed cost allocation.
  • Unused material is undamaged and available for future production batches.

Frequently Asked Questions

Why can’t I expense all purchased materials immediately?

Under standard GAAP and tax accounting rules, raw materials must be capitalized into inventory assets upon purchase. They only convert into manufacturing expenses as they are physically consumed in production.
