### INTRODUCTION TO FIXED INSTALLMENT METHOD

Straight line method is also known as fixed installment, fixed percentage and original cost method. Fixed installment method is one of the methods of allocating depreciation. In this method, every year a fixed amount of depreciation is deducted from the value of assets and the same amount is debited to profit and loss account. The book value of the assets is reduced to zero at the end of the expected life. The formula for calculating the amount of depreciation is as follows:

Annual Depreciation = (Original Value – Scrap Value)/Estimated life of the assets

If the rate of depreciation is given, the depreciation is calculated with the help of the following formula:

Annual Depreciation = Original Value× $$\frac{Rate \;of \;depreciation}{100}$$

If the rate of depreciation has to be determined:

Rate of Depreciation = $$\frac{1}{Life\;of\; Asset}$$ × 100

Or

Rate of Depreciation = $$\frac{Amount \;of\; Depreciation}{Depreciable\; Value}$$ × 100

#### Advantage of Fixed Installment Method

The advantages of fixed installment method are as follows:

• This method is suitable for those assets whose working life can easily be estimated.
• It is simple to understand and easy to calculate.
• The valuation of the assets takes place appropriately every year in the Balance Sheet.

The disadvantages of fixed installment of method are as follows:

• It is not suitable for those assets which are subject to addition and extension from time to time.

ILLUSTRATION 1

Following information is given:

1. Purchase price of furniture Rs.40000
2. Carriage and installation charge Rs. 8000
3. Scrap value Rs. 10000
4. Rate of depreciation is @20% p.a

Required:

1. Amount of depreciation
2. Journal entries and furniture account for three year

Solution

Annual Depreciation = (Purchase price + carriage and installation charges – scrap value) × $$\frac{Rate\; of\; depreciation}{100}$$

= (40000 + 8000 – 10000) × $$\frac{20}{100}$$

= Rs. 8400 p.a.
