Depreciation vs a fall in market value

An asset in the accounts can seem to shrink for two different reasons, and students often mistake one for the other. The first is depreciation, the yearly charge that reduces a non-current asset’s carrying figure. The second is a fall in market value: the asset is worth less to a buyer than it once was.

Both describe an asset heading down, so it is tempting to treat them as one event. They are not. Different forces drive them, they follow different rules, and they often move at different speeds, even in opposite directions.

Depreciation is a planned sharing of cost

Depreciation is a decision made when the asset is bought, not a reaction to the market. The business estimates how long the asset will be useful and picks a method to spread its cost over those years. From then on, the charge follows the plan.

This is the matching concept in action. An asset helps earn income for several years. Its cost should be spread across those years, not all charged in the year of purchase.

So the yearly charge answers an internal question: how much of what we paid belongs to this period? The policy fixes the answer. The second-hand market does not.

Suppose a bakery buys an oven for RM24,000 and expects eight years of use. Charging RM3,000 a year simply follows the plan set at the start.

A fall in market value is an outside event

A fall in market value is something the wider world does to the asset. Prices for used equipment rise and fall with demand, the condition of the item, newer models and the economy.

None of this is under the owner’s control, and none of it follows a neat annual pattern. A machine might hold its resale price for years and then drop sharply when a better model appears.

Market value is what a willing buyer would pay now. It sits outside the business’s records and moves to its own rhythm.

Why the two need not move together

One is a plan and the other is a market, so they often disagree. A building may be depreciated steadily on paper while local property prices climb. The recorded figure falls just as the asset becomes more valuable to sell.

Technology shows the opposite. Resale value can collapse within a year or two as newer equipment arrives, far faster than a gentle depreciation charge.

This is why the net book value of an asset, its cost less depreciation charged so far, rarely equals what it would fetch if sold. The gap is not an error to correct. It is the result of two unrelated processes measured side by side.

Why everyday market movements stay out of the accounts

Market values move constantly, yet the accounts largely ignore them for non-current assets. The reason is what those assets are for.

A business holds machines, vehicles and buildings to use them, not sell them. This is the going concern assumption: the business is expected to keep operating, not close and sell everything.

If an oven will be used for baking, the price it might fetch this week matters little. What matters is that its cost is shared fairly over the years it serves. Restating resale prices each year would also make the accounts less reliable, because those prices rest on opinion, not on a completed sale.

When a real loss of value does enter the accounts

There is one important exception. If an asset’s worth to the business falls sharply and lastingly, not a passing dip but a real, permanent decline, prudence applies.

Accounts should not carry an asset at more than it is worth to the business. So where a serious, lasting fall can be seen, the carrying figure is reduced.

This is not depreciation. Depreciation is a routine, scheduled sharing of cost. This reduction responds to a specific event and exists because caution forbids overstating the asset. The trigger, timing and reasoning are different, even though both lower the same figure.

The two figures answer different questions

Depreciation answers: “How much of this asset’s cost should this year carry?” A fall in market value answers: “What would somebody pay for this asset now?”

The first is about spreading a past payment fairly over time. The second is about a present price in an outside market.

Once you see that the accounts answer the first question, several misreadings disappear. The statement of financial position is not a price list, and a heavily depreciated asset is not necessarily nearly worthless.

Why keeping them apart matters

Confusing the two distorts how a student reads a business. They may think a depreciation charge measures how much resale value was lost that year.

They may also think a well-kept asset should escape depreciation because it still works perfectly. Neither idea holds up once the two are separated.

Depreciation keeps spreading the cost of a useful asset whatever the market does. The market keeps repricing the asset whatever the depreciation policy is.

Can your child calculate depreciation but still think it tracks what an asset is worth? One of our teachers can work through clear figures with them.
