• Gross Income ➔ Net Income +Expenditure

Type of Expenditure

1) Taxation

• Taxiation is about 14%

2) Repairness

• It is spent of the repairness of the bounding libs white whishing, crack filling etc.

3)Management & Collection charge

• It is used for the management of a society/home like as electricity bill,watchmen etc.


Scrap Value

• It is taken as about 10% of the total value of a property after its utility period(guarantee period)

• It is the value of dismantle material

• The cost of dismantling & removal of rubbish material is deducted from total receipt obtain from sale of usable material.


Salvage Value

• It is the value at the end of utility period without being dismantled.

• The cost of dismantling & removal of rubbish material is not deducted from the total receipt

Note :- 1). Salvage value & Scrap value may be positive, negative & zero. 

2). For the RCC structure, scrap value & salvage value are always negligible.


Sinking Fund

I = SL/(1+i)n-1

Where, S = Total Sinking Fund

L = Annual installment of sinking fund

i = Rate of Compound interest

n = no.of utility period


Market Value

It is the value of a property if it is put in open market for auction 


Book Value

• Book value decreases year to year gradually.

• It depends upon life period of the building property & its depreciation amount.

• After the end of utility period, book value is equal to the scrap value.

Book value = value of the property upto that year Depreciation allowed for that year


Depreciation

It is the gradual reduction in the price of a property/building.

Due to obsolescence, design change etc.

Following are the method for the calculation of depreciation.

1)Straight line method

In this method we assume depreciation in the form of fix amount.

D = C-S/n                 ➔ LEARN


Where D = Depreciation 

S = Scrap value

C = Original cost of construction 

n = no. fo utility period

Book value after N year = C-(NxD) 

2)Constant Percentage Method

• This method is also called Balancing Decline method.

• In this method, we assume that the depreciation is taken as fix percentage.

D = 1 -{C/S}1/n                            ➔ Learn
