2. Depreciation
• Any equipment which is purchased today will not work for ever.
– Due to Wear & Tear, Becoming out of Date
• Successful company has to take the decision, when to replace the
old equipment
• Replacement Involves Money.
– This should be internally generated from the earnings of the equipment.
(depreciation Fund).
• Depreciation means decrease in value of any physical asset
with the passage of time.

throughout the life time.
• Accumulated sum at the end of life is equal to the
purchase value of the asset. MG6863 S.BALAMURUGAN, AP/MECH AAACET

4. Straight Line Method of Depreciation
• Himalaya Drug Company has just purchased a capsulizing machine for Rs. 10, 00,000.
The plant engineer estimates that the machine has a useful life of 5 years and a salvage
value of Rs. 10,000 at the end of its useful life. Compute the depreciation schedule for
the machine by each of the following depreciation methods : i) Straight line method of
depreciation.
• Solution:
• P = Rs. 10,00,000 n=5 years F = Rs. 10,000

5. • More realistic approach, the depreciation charges decreases
with the life of the asset which matches the earning potential of
the asset.
• Constant percentage of the book value of the previous period of
the asset will be charged as the depreciation amount for the
current period.
• Depreciation, Dt = K × Bt-1 Book Value (Bt) = Bt-1 - Dt
• Fixed Percentage K = limited to 2/n.
• Generally Assume K = 0.2

6. Declining Balance method of depreciation
• A company has purchased an equipment whose first cost is Rs.1,00,000 with an
estimated life of eight years. The estimated salvage value of the equipment at the
end of its lifetime is Rs.20,000. Determine the depreciation charge and book value
at the end of various years using decline balance method of depreciation by
assuming K=0.2
• Solution: P = Rs.1,00,000 F = Rs.20,000 n = 8 Years K=0.2(Assume)
Depreciation, Dt = K × Bt-1 Book Value (Bt) = Bt-1 - Dt
End of Year (n) Depreciation (Dt ) (Rs.) Book Value (Bt) (Rs.)

2 80,000 × 0.2 = 16,000 80,000 – 16,000 = 64,000
3 64,000 × 0.2 = 12,800 64,000 – 12,800 = 51,200
4 51,200 × 0.2 = 10,240 51,200-10,240 = 40,960
5 40,960 × 0.2 = 8,192 40,960 – 8,192 = 32,768
6 32,768 × 0.2 = 6,553.60 32,768 – 6,553.60 = 26,214.40
7 26,214.40 × 0.2 = 5,242.88 26,214.40 – 5,242.88 = 20,971.52

7. Sum of Years Digit Method of Depreciation
• In this method, it is assumed that the book value of the asset
decreases at a decreasing rate.
• Step 1 – Find Sum of Years
– Example – 5 Years life
– Sum of Years = 1+2+3+4+5 = 15 =
𝒏(𝒏+𝟏)
𝟐
• Rate of depreciation for the years 1-5 = 5/15, 4/15, 3/15, 2/15, 1/15
• Step 2
– Depreciation, Dt = Rate × (P-F)
– Book Value (Bt) = Bt-1 - Dt

8. Sum of Years Digit Method of Depreciation
• The cost of the machine is Rs.1,00,000 and its scrap value is Rs.40,000.
Estimate life 5 years. Using sum of years digit method, determine
depreciation charges for each year.
• Solution
– 5 Years life
– Sum of Years = 1+2+3+4+5 = 15 =
𝒏(𝒏+𝟏)
𝟐
– Rate of depreciation for the years 1-5 = 5/15, 4/15, 3/15, 2/15, 1/15

2 Rate (4/15) = (4/15) × (1,00,000 – 40,000) = 16,000 = 80,000 – 16,000 = 64,000
3 Rate (3/15) = (3/15) × (1,00,000 – 40,000) = 12,000 = 64,000 – 12,000 = 52,000
4 Rate (2/15) = (2/15) × (1,00,000 – 40,000) = 8,000 = 52,000 – 8,000 = 44,000
5 Rate (1/15) = (1/15) × (1,00,000 – 40,000) = 4,000 = 44,000 – 4,000 = 40,000

9. Annuity Method or Sinking Fund Method of
Depreciation
• In this method of depreciation, the book value decreases at increasing
rates with respect to the life of the asset.
• Step 1
– Find Equal depreciation amount for Loss in value of asset (P – F)
– A = (P – F) × [A/F, i ,n]
• Step 2
– Depreciation Dt = (P – F) × (A/F, i ,n) × (F/P, i, t – 1)
– Book Value (Bt) = P – (P – F) × (A/F, i ,n) × (F/A, i, t )

10. Annuity Method or Sinking Fund Method
of Depreciation
• Find the depreciation annuity by Annuity method after three years,
when the initial cost of the machine is Rs.8,00,000 and the salvage
value at the end of three years is Rs.4,00,000. Rate of interest 10%.
• Solution:
• A = (P – F) × (A/F, i ,n)
= (8,00,000 – 4,00,000) × (A/F, 10% ,3) =(4,00,000 × 0.3021)
A = Rs.1,20,840
• Method 1
• Depreciation Dt = (P – F) × (A/F, i ,n) × (F/P, i, t – 1)
At Year 1, D1 = 1,20,840 × (F/P, i, 1 – 1) = Rs. 1,20,840
At Year 2, D2 = 1,20,840 × (F/P, i, 2 – 1) = 1,20,840 × (F/P, i, 1)
= 1,20,840 × (1.100) = Rs. 1,32,924
At Year 2, D2 = 1,20,840 × (F/P, i, 3 – 1) = 1,20,840 × (F/P, i, 2)
= 1,20,840 × (1.210) = Rs. 1,46,216.4MG6863 S.BALAMURUGAN, AP/MECH AAACET

Maximum profit. The main goal is to provide goods/service as per
specifications with Maximum Profit.
• For Public Organizations / Government Organizations / Govt. Projects
• The same condition is not applicable for Evaluation of Public Alternatives.
• The main objective of any public alternative is to provide goods/service to
the public at the minimum cost.
• In this case, the benefits of the public alternative are at least equal to its
costs. (BC ratio = 1 or >1) If yes, then the public alternative can be taken
for implementation.

15. • Two mutually exclusive projects are being considered for investment. Project A1 requires an initial
outlay of Rs. 30, 00,000 with net receipts estimated as Rs. 9, 00,000 per year for the next 5 years.
The initial outlay for the project A2 is Rs. 60, 00,000, and net receipts have been estimated at Rs.
15, 00,000 per year for the next seven years. There is no salvage value associated with either of the
projects. Using the benefit cost ratio, which project would you select? Assume an interest rate of
10%.
