Effects of incorrect valuations

How does an incorrect valuation of inventory affect profit?

  • Inventory valuation affects both the gross profit and the profit for the year

    • Both are affected in the same way and by the same amount

  • The opening inventory value is debited to the income statement

    • The opening inventory is an expense that is matched to the current financial period’s revenue

    • It is added to the cost of sales for the current period

    • Therefore, opening inventory decreases the profit

  • The closing inventory value is credited to the income statement

    • The closing inventory is an expense that is matched to the next financial period’s revenue

    • It is subtracted from the cost of sales for the current period

    • Therefore, closing inventory increases the profit

  • The table below shows how incorrect inventory valuation affects the gross profit and the profit for the year

    • The effects depend on whether it is the opening or closing inventory

Effects if inventory is undervalued

Effects if inventory is overvalued

Opening inventory

Gross profit and profit for the year are overstated

Gross profit and profit for the year are understated

Closing inventory

Gross profit and profit for the year are understated

Gross profit and profit for the year are overstated

How does an incorrect valuation of inventory affect capital and asset valuation?

  • Inventory valuation affects both the capital and the asset valuation

  • At the end of a financial period, the closing inventory is stated on the statement of financial position under current assets

    • Therefore, the valuation of the closing inventory directly affects the asset valuation

  • The opening inventory is not stated on the statement of financial position

    • Therefore, the valuation of the opening inventory has no effect on the asset valuation

  • The valuation of the closing inventory also affects the capital value in the statement of financial position

    • It affects the profit for the year, which is recorded as an element of capital in the statement of financial position

  • The valuation of the opening inventory has no affect on capital at the end of the current period

    • The profit for the previous period would have been understated or overstated

      • This would mean the capital at the end of the previous period was incorrect

    • The profit for the current period would be understated or overstated

      • This would normally affect the capital at the end of the current year

    • However, the effects cancel each other out so that the capital at the end of the current year is unaffected

  • The table below shows how incorrect inventory valuation affects capital and asset valuation

    • The effects depend on whether it is the opening or closing inventory

Effects if inventory is undervalued

Effects if inventory is overvalued
