Lower of cost and NRV: Compare inventory cost with net realisable value and calculate any write-down.

Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Lower of cost and NRV to answer this question: compare inventory cost with net realisable value and calculate any write-down? Enter Recorded inventory cost, Expected selling value, Completion and selling costs; the calculator shows Permitted carrying amount. Try changing one number and watch what happens to Permitted carrying amount. The answer tells you Permitted carrying amount.

Age 15Explain it to a 15-year-oldConnect it to the formula

Inventory is not carried above the amount expected to be realised from its sale, subject to the applicable reporting framework. The rule is NRV = selling price − completion and selling costs; carrying amount = lower of cost and NRV. Its input values are Recorded inventory cost, Expected selling value, Completion and selling costs, and the main result is Permitted carrying amount. Try changing one number and watch what happens to Permitted carrying amount.

CollegeExplain it at college levelState the model precisely

This calculator evaluates one accounting relationship within a consistent entity, currency, reporting period and recognition policy. The implemented relation is NRV = selling price − completion and selling costs; carrying amount = lower of cost and NRV, evaluated from Recorded inventory cost, Expected selling value, Completion and selling costs to produce Permitted carrying amount. Inventory is not carried above the amount expected to be realised from its sale, subject to the applicable reporting framework. Recognition, measurement, tax, consolidation, foreign-currency and disclosure rules may require adjustments under the accounting framework that applies to the entity.

What this accounting tool does

Compare inventory cost with net realisable value and calculate any write-down.

Why the relationship works

Inventory is not carried above the amount expected to be realised from its sale, subject to the applicable reporting framework.

The accounting formula

NRV = selling price − completion and selling costs; carrying amount = lower of cost and NRV

Inputs and period consistency

This model uses Recorded inventory cost, Expected selling value, Completion and selling costs. Use the same reporting period, currency, entity boundary and accounting policy for every input.

What the result means

The primary output is Permitted carrying amount; supporting outputs include Net realisable value, Inventory write-down. Trace each amount back to the relevant ledger or statement line before relying on it.

Limits of this compact model

The calculator teaches one relationship. Recognition, measurement, tax, consolidation, foreign-currency and disclosure rules may require additional adjustments under the framework that applies to the entity.

Frequently asked questions

What does the Lower of cost and NRV do?

Compare inventory cost with net realisable value and calculate any write-down.

How does the Lower of cost and NRV work?

The calculator applies NRV = selling price − completion and selling costs; carrying amount = lower of cost and NRV. Inventory is not carried above the amount expected to be realised from its sale, subject to the applicable reporting framework.

What can I learn from the Lower of cost and NRV?

You will connect Recorded inventory cost, Expected selling value, Completion and selling costs to Permitted carrying amount, then see how the relationship belongs in the accounting process.

Does MW SysArc receive or store what I enter?

No. The calculation runs locally in your browser. MW SysArc does not receive or store your calculation inputs.

How should I use the result?
