How to use the stock value calculator
Stock value is what your inventory cost you, not what you hope to sell it for. It is the figure that goes on the balance sheet, and the base for insurance and financing.
- Add one line for each product you hold.
- Enter the quantity on hand, taken from a physical count or from your stock records.
- Enter the unit cost: the purchase price plus the costs of bringing the product in, such as freight and duties.
- Read the total. Each line is quantity × unit cost, and the stock value is the sum of all lines.
Worked example
120 units at 15 = 1,800. 40 units at 85 = 3,400. 300 units at 2.50 = 750.
Total stock value = 1,800 + 3,400 + 750 = 5,950.
The second product is 40 of the 460 units but 57% of the value. That is where a counting error costs the most.
Which unit cost to use
| Method | How it works |
|---|---|
| FIFO (first in, first out) | The oldest purchases are treated as sold first, so the stock left is valued at the most recent prices. |
| Weighted average cost | Every unit carries the average cost of all purchases, recalculated after each delivery. |
| Same purchases, two results | Buy 100 units at 10, then 100 at 12, and sell 120. FIFO values the 80 left at 12, so 960. Weighted average values them at 11, so 880. |
Common mistakes
- Valuing stock at the selling price. Stock is valued at cost, or at what it can still be sold for when that is lower.
- Keeping damaged, expired or obsolete goods at full cost. Write them down.
- Including recoverable VAT in the unit cost.
- Changing valuation method from one year to the next, which makes the figures impossible to compare.
Frequently asked questions
Should stock be valued at cost or at selling price?
At cost. Accounting standards require the lower of cost and net realisable value, which is the price the goods can still be sold for, less the costs of selling them.
How often should I value my stock?
At least once a year for the annual accounts. A monthly valuation is more useful for managing cash, because it shows early when stock is growing faster than sales.
Do goods in transit count?
They count once ownership has passed to you, which depends on the delivery terms agreed with the supplier.
Is stock held by a customer on consignment still mine?
Yes. Consignment stock belongs to you until the customer sells it, so it stays in your stock value.
