Depreciation refers to that portion of the value of an asset that is written off over the useful life of the asset due to wear and tear.
Now, when we talk about depreciation, there are multiple methods to calculate depreciation such as:
- Straight Line Depreciation Method
- Diminishing Balance Method Or Written Down Value Method
- Sum of Years’ Digits Method
- Double Declining Balance Method
- Sinking Fund Method
- Annuity Method
- Insurance Policy Method
- Discounted Cash Flow Method
- Use Based Methods
- Output Method
- Working Hours Method
- Mileage Method
- Other Methods
- Depletion Method
- Revaluation Method
- Group or Composite Method
The most commonly used methods are discussed below:
1. Straight Line Depreciation Method: This is the simplest method for calculating depreciation where a fixed amount of depreciation is charged over the useful life of the asset.
Formula:
Suppose a company Bear Ltd purchases machinery costing 8,00,000 with useful life of 10 years and salvage value 1,00,000. Then depreciation charged to the machinery each year would be:
Depreciation = (8,00,000 – 1,00,000)/10 = 7,00,000/10 = 7,000 p.a.
2. Diminishing Balance Method Or Written Down Value Method: Under this method, a fixed rate of depreciation is charged every year on the opening balance of the asset which is the difference between the previous year’s opening balance and the previous year’s depreciation. Here the book value of asset reduces every year and so does the depreciation amount.
Formula:
Suppose a company Moon ltd purchases a building for 50,00,000 with a useful life of 5 years and decides to depreciate it @ 10% p.a. on Diminishing Balance Method. Then depreciation charged to the machinery would be:

3. Sum of Years’ Digits Method: In this method, the life of asset is divided by the sum of years and multiplied by the cost of the asset to determine the depreciating expense. This method allocates higher depreciation expense in the early years of the life of the asset and lower depreciation expense in the latter years.
Formula:
Suppose a company Caps Ltd purchases machinery costing 9,00,000 having a useful life of 5 years. Then the depreciation cost would be:

4. Double Declining Balance method: This method is a mixture of straight-line method and diminishing balance method. A fixed rate of depreciation is charged on the reduced value of the asset at the beginning of the year. This rate is double the rate charged under straight-line method.
Formula:
Suppose a company Paper Ltd purchases machinery for 1,00,000 with an estimated useful life of 8 years. Then the depreciation rate would be:
Straight line = 100%/8 = 12.5%
Double declining method = 2*12.5% = 25%

5. Sinking Fund Method: Under this method, the amount of depreciation keeps on accumulating till the asset is completely worn out. Depreciation is the same every year. Profits equal to the amount of depreciation is invested each year outside the company. At the time of replacement of the asset the investments and sold and the proceeds thereof are used to purchase the new asset.
6. Annuity Method: This method calculates depreciation by calculating its internal rate of return (IRR). Depreciation is calculated by multiplying the IRR with an initial book value of the asset, and the result is subtracted from the cash flow for the period.
7. Use Based Methods: Depreciation, under these methods, is based on the total estimated machine hours or total estimated units produced during the life of the machine. It is calculated by dividing the cost of the machine by the estimated total machine hours or estimated lifetime production in units and multiplying by the units produced or machine hours worked.
Formula:
Suppose a company Box Ltd purchases machinery for 25,000 (estimated life 5 years) whose estimated life production is 5,000 units. If it produces 700 units in the first year of operation then depreciation cost would be:
Depreciation = 25,000/5,000*700 = 3,500

All expenses whose benefits are received over the years or the expenses or losses that are to be written off over the years are classified as Deferred revenue expenses. It includes fictitious expenses like preliminary expenses, loss on issue of debentures, advertising expenses, loss due to unusual occurrences like loss due to fire, theft, and research and development expenses, etc.
DEFERRED REVENUE EXPENSES
There are certain expenses which are revenue in nature (i.e. expenses incurred to maintain the earning capacity of the firm and generate revenue) but whose benefits are received over a period of years generally between 3 to 7 years. It means its benefit is received not only in the current accounting period but over a few consecutive accounting periods.
CHARACTERISTICS
EXAMPLES
ADVERTISING EXPENSES refers to the expenses incurred for promoting the goods or services of the firm through various channels like TV, Social media, Hoardings, etc.
As the benefit of advertising is not received not only in the period when such expenses were incurred but also in the coming few years, it is classified as Deferred revenue expense.
For example – Suppose the company incurred $10 lakh on advertising to introduce a new product in the market and estimated that its benefit will last for 4 years. In this case, $250,000 will be written off every year, for 4 consecutive years.
EXCEPTIONAL LOSSES are losses that are incurred because of some unusual event and don’t happen regularly like loss from fire, theft, earthquake, flood or any other natural disaster, confiscation of property, etc.
Since these losses can’t be written off in the year they occurred they are also treated as Deferred revenue expenditure and are written off over the years.
RESEARCH AND DEVELOPMENT EXPENSES are expenses incurred on researching and developing new products or improving the existing ones. Its benefits are received for many years and thus are classified as Deferred revenue expenses.
For example – Expenses incurred on the creation of intangible assets like patents, copyrights, etc.
PRELIMINARY EXPENSES are those expenses which are incurred before the incorporation and commencement of the business. It includes legal fees, registration fees, stamp duty, printing expenses, etc.
These expenses are fictitious assets and are written off over the years.
TREATMENT
It is debited to the P&L amount (amount written off that year) and the remaining amount on the Aeest side of the Balance Sheet.
In the above example of advertising expenses, in Year 1, $250,000 will be debited in the P&L A/c and the remaining amount of $750,000 is shown on the Asset side of the Balance Sheet.
In Year 2, $250,00 in P&L A/c and the remaining $500,000 in Balance Sheet.
In Year 3, $250,000 in P&L A/c and the remaining $250,000 in the Balance Sheet and in the last Year 4, only the remaining amount of $250,000 in P&L A/c and nothing in the Balance Sheet.
