Final Accounts Adjustments: How Depreciation & Closing Stock Ripple Through Every Statement

Most students learn the Trading A/c, the Profit & Loss A/c and the Balance Sheet as three separate formats to be memorised. The exam, however, tests the one thing those separate formats hide: they are a single connected machine. Change one adjustment and the effect travels through all three statements at once.

This is where marks quietly disappear. A student applies depreciation in the P&L but forgets it also reduces the asset on the Balance Sheet. Or records closing stock in the Trading A/c but forgets it is also a current asset. The numbers stop tying out — and the examiner notices.

Feel the connection for yourself

The worked example below is live. Drag the Depreciation or Closing Stock slider and watch every linked figure recalculate across all three statements. Notice the balance indicator: no matter what you change, the Balance Sheet always balances. That is double-entry proving itself.

Why depreciation has a double effect

Depreciation is the classic two-mark trap because it touches the statements in two places at once:

• In the Profit & Loss A/c, it is an expense — so it reduces Net Profit.
• On the Balance Sheet, it reduces the book value of the asset (Machinery).

Raise the rate from 10% to 15% in the tool above and you will see Net Profit fall, the closing Capital fall by the same amount (because Net Profit flows into Capital), and Machinery fall by the same amount on the assets side. Both sides drop together — the sheet stays balanced.

Why closing stock also appears twice

Closing stock is the other figure students record only once. It belongs in two places:

• Credited in the Trading A/c (it lifts Gross Profit).
• Shown as a current asset in the Balance Sheet.

Increase closing stock in the tool and Gross Profit rises, carrying Net Profit and Capital up with it, while the asset side rises by the same amount.

Exam takeaway

When you see an adjustment in a Final Accounts question, always ask: "Where does this land — and does it land more than once?" Depreciation and closing stock each land twice. Trace both legs before you total, and your Balance Sheet will tie out the first time.
