Mistaken idea “One inventory measurement formula fits every population”

Mistaken reasoning: This mistake applies direct NRV or designated market without first identifying the inventory method and evidence population.

Updated Sep 10, 2026 Review due Dec 10, 2026

Why this is mistaken

Identify the inventory method first. Build NRV from a supported selling price less applicable completion, disposal, and transportation costs. Use direct NRV for the in-scope ordinary population. Constrain replacement cost between the ceiling and floor for LIFO or retail-method inventory.

Where to watch

When this mistake may appear

  • Use MIN(cost, NRV) for every SKU.
  • Market always means replacement cost.
  • List price is NRV.
Check your work

Your work may contain this mistake if:

  • Skips the cost-method route, omits NRV deductions, or uses replacement cost without the ceiling and floor.
