How to value inventory
A problem-to-playbook guide to valuing inventory correctly - from choosing a costing method to reserving for obsolescence - so your balance sheet is defensible.
Why inventory valuation trips people up
Inventory looks like one number on the balance sheet, but it’s the product of several decisions: which costing method you use, how you value every receipt and issue, and how aggressively you reserve for stock that won’t sell at cost. Get any of them wrong and both your assets and your margins are off.
What a defensible valuation needs
- A chosen, consistent costing method
- Every movement valued by that method
- A reserve for excess and obsolete stock
- Gross, reserve, and net value reported
The steps
Valuing inventory end to end
- 1
Choose a costing method
Pick weighted-average, FIFO, or standard per item - and apply it consistently. (LIFO is a separate regime Fintra doesn’t support.)
- 2
Value each movement
Recompute the moving average on each receipt, or relieve FIFO layers oldest-first, or value at standard and book variances.
- 3
Compute gross value
Multiply on-hand quantity by unit cost per item for the gross inventory value.
- 4
Reserve for E&O
Take the most conservative of aging, specific-ID, and lower-of-cost-or-NRV reserves per item.
- 5
Report net value
Net value = gross value − reserve; report all three for transparency.
How the method changes the number
| Method | COGS | Inventory value |
|---|---|---|
| FIFO | Lower (old, cheaper costs) | Higher (recent costs) |
| Weighted average | Middle | Middle |
| Standard | At standard; drift → variances | At standard |
How Fintra does it
Fintra applies your chosen method on every movement, keeps a stock ledger with a running quantity for audit, computes the E&O reserve as the most conservative policy, and reports gross, reserve, and net value per item and in total - so the balance-sheet number is fully explained.
Frequently asked questions
How do you value inventory?
Choose a costing method (weighted-average, FIFO, or standard), value every receipt and issue by that method, multiply on-hand quantity by unit cost for gross value, then subtract an excess-and-obsolete reserve to get net value. Report gross, reserve, and net for transparency.
Which inventory costing method should I use?
It depends on your reporting needs and industry, but the key rule is consistency. FIFO tends to show higher inventory value and lower COGS when prices rise; weighted average smooths cost; standard costing makes production comparable and surfaces variances. Fintra supports all three (not LIFO).
What is net realizable value in inventory?
Net realizable value (NRV) is the estimated selling price less the costs to complete and sell an item. When cost exceeds NRV, inventory should be written down - a lower-of-cost-or-NRV reserve - so the balance sheet doesn’t carry stock above what it can recover.
How does Fintra keep inventory valuation auditable?
It applies your chosen method automatically on every movement, maintains a stock ledger with a running quantity, computes the E&O reserve as the most conservative of three policies, and reports gross, reserve, and net value - so every figure traces back to real transactions.
