Depreciation is also called Consumption of Fixed Capital (CFC).
It measures the annual loss in the value of fixed assets.
Land is generally not depreciated because it has an unlimited useful life.
Depreciation is deducted from Gross Investment to obtain Net Investment.
NDP = GDP − Depreciation
NNP = GNP − Depreciation
Depreciation is an accounting provision, not necessarily a cash expenditure.
It generally excludes losses arising from extraordinary events such as wars or major natural disasters in national income accounting.

Depreciation refers to the loss in the value of capital goods due to regular use, wear and tear, ageing or obsolescence. In macroeconomics, depreciation is important because capital goods such as machines, tools, factory buildings, vehicles and equipment are used repeatedly in production, but they do not last forever.Every year, a part of the existing capital stock gets used up in the production process. This annual loss in the value of capital is called depreciation.

For example, if a machine is used in a factory for several years, it may become less efficient due to continuous use. Its parts may wear out, maintenance costs may rise, and after some time it may need replacement.

Depreciation is also known as consumption of fixed capital.

Depreciation — Key Takeaways

Tangible asset: Depreciation applies to physical assets expected to last for more than one year (often called fixed assets or capital assets).
Certain assets, such as land, are not depreciated as they are considered to have an unlimited useful life.
It helps businesses track asset values, manage taxes effectively, and plan for future replacements by distributing costs over time.
Depreciation does not take into account unexpected or sudden destruction or disuse of capital as can happen with accidents, natural calamities or other such extraneous circumstances.

Depreciation as an Accounting Concept

Depreciation is mainly an accounting concept.This means that actual money may not be spent every year on replacing a machine or building, but depreciation is still recorded every year in accounts.
For example, suppose a machine is expected to work for 10 years. The firm may not replace the machine every year. However, because the machine is gradually losing value, a part of its value is recorded as depreciation each year.
Thus, depreciation helps estimate how much of the value of capital goods has been used up during a year.

Examples

Example of Depreciation

Suppose a farmer buys a tractor worth ₹10 lakh.
The tractor is expected to be used for 10 years.
If we assume equal depreciation every year, then:
- Annual Depreciation = Cost of Tractor / Useful Life
- Annual Depreciation = ₹10 lakh / 10 years = ₹1 lakh per year
This means that every year, the tractor loses value worth ₹1 lakh due to use, ageing and wear and tear.
After one year, the value of the tractor may be treated as:
- ₹10 lakh – ₹1 lakh = ₹9 lakh
- Here, ₹1 lakh is depreciation.

Example in an Economy

Suppose an economy has old machines, buildings and equipment.
During the year, these capital goods suffer wear and tear worth ₹40 crore.This ₹40 crore is called depreciation.
If the economy produces capital goods worth ₹200 crore, then:
- Gross Investment = ₹200 crore
- Depreciation = ₹40 crore
- Net Investment = Gross Investment – Depreciation= ₹200 crore – ₹40 crore = ₹160 crore
This means that although the economy produced capital goods worth ₹200 crore, ₹40 crore worth of existing capital was lost due to wear and tear.
Therefore, the actual new addition to the economy’s capital stock is only ₹160 crore.

Why Depreciation Happens?

Regular Wear and Tear:Machines, vehicles, tools and equipment lose value when they are used repeatedly in production.
Ageing of Capital Goods:Even if a capital goods is not used heavily, it may lose value over time due to age.
Technological Obsolescence:A machine may become outdated when better technology becomes available. Even if the old machine is still working, its economic value may fall.
Accidental Damage:Capital goods may also lose value due to fire, flood, accident or other unexpected events.
Lack of Maintenance:Poor maintenance reduces the life and efficiency of capital goods, increasing depreciation.

Need for Providing Depreciation

Depreciation is provided because fixed assets such as machines, tools, vehicles, buildings and equipment lose value over time due to use, wear and tear, ageing and obsolescence. If depreciation is not recorded, the value of assets and profits of a business or economy may be overstated.

To Show True Value of Assets
- Fixed assets do not retain the same value throughout their life. A machine purchased for ₹10 lakh will lose value after repeated use.
- Depreciation helps show the realistic value of assets in the books of accounts.
To Calculate Correct Profit
- Depreciation is an expense. If it is not deducted from revenue, profit will appear higher than the actual profit.
- Thus, depreciation is provided to calculate true and fair profit.
To Provide for Replacement of Assets
- Assets wear out and need replacement after some time.
- By charging depreciation every year, a business recognises the cost of using the asset and can plan for its future replacement.
To Match Cost with Revenue
- A fixed asset is used for many years to generate revenue.
- Depreciation spreads the cost of the asset over its useful life so that each year bears a fair share of the asset’s cost.
To Avoid Overstatement of Income
- If depreciation is ignored, expenses will be understated and income will be overstated.
- This may create a false picture of business performance.
To Avoid Overstatement of Capital
- If depreciation is not provided, the value of assets shown in the balance sheet will remain artificially high.
- This also leads to overstatement of capital or net worth.
To Follow Accounting Principles
- Depreciation is provided according to the matching principle and accrual concept of accounting.
- It ensures that expenses are recorded in the same period in which related revenue is earned.
To Measure Net Investment in the Economy
- In macroeconomics, depreciation is deducted from gross investment to calculate net investment.
- Net Investment = Gross Investment – Depreciation
- This helps measure the actual new addition to capital stock.
- Example
  - Suppose a machine is bought for ₹5 lakh and is expected to be used for 5 years.
  - If depreciation is calculated equally every year:
  - Annual Depreciation = ₹5 lakh / 5 years = ₹1 lakh
  - This means ₹1 lakh is treated as the cost of using the machine every year.
  - If depreciation is not provided, the machine may still be shown at ₹5 lakh after one year, even though its actual value has reduced.

Depreciation is an important concept in macroeconomics because it shows the gradual loss in the value of capital goods due to regular use, wear and tear, ageing and obsolescence. Since machines, tools, buildings and equipment do not last forever, a part of their value is considered to be used up every year in the production process.

Understanding depreciation helps us distinguish between gross investment and net investment. Gross investment shows the total production of capital goods, while net investment shows the actual new addition to the economy’s capital stock after deducting depreciation. Therefore, depreciation is essential for measuring real capital formation, productive capacity and the true growth potential of an economy.
