13. Depreciation:-
Gradual decrease in the value of an asset
is known as depreciation.
It has two types:-
1- Internal depreciation.
2- External depreciation.
15. Internal Depreciation:-
Depreciation which occurs for certain
inherent normal causes, is known as internal
depreciation. Such as wear and tear and
depletion.
External Depreciation:-
Depreciation caused by some external
reasons is called external depreciation. Such as
obsolescence, efflux of time and accident.
17. Wear and Tear:-
The change in the shape of an asset due to
use in the business is known as wear and tear.
Obsolescence:-
The decrease in the value of an asset due to
new inventories, change in habit and taste of
people, improvement and change in technology
and fashion is known as obsolescence.
18. Methods of depreciation
• Uniform charge method
• Diminishing method
Uniform charge method:-
In this case method of depreciation is charged on
uniform basses year after year.
19. Types of Uniform Charge method
• Straight line method
• Depletion method
• Machine rate method
20. Straight Line Method Of
Depreciation
Under this method depreciation of an asset
will be equal in each accounting year, it is also
known as straight line method.
21. Formula of straight line method
Depreciation= Original cost of an asset- scrap value
Estimated life
For percentage of depreciation:-
Depreciation ×
Depreciation × 100
Original asset
22. Market price of an assets:-
Scarp value of an asset:-
Working Life of an asset:-

Assets-Depreciation
10000-2500=7500
24. Depletion method or Production output
method:-
Decrease in the value of wasting asset is
called depletion.
Wasting Assets:-
Assets whose value gradually reduces on account
of use and finally exhausts completely are called wasting
assets, e.g. mine, forest, machinery etc
25. Detail:-
In this method the charge of depreciation
In respect of use of an asset will be based on the
following factors.
i. Total amount paid.
ii. Total estimated quality of output available.

27. Apex Mining acquired a tract of land
containing ore deposits. Total costs of
acquisition and development were
$1,000,000 and Apex estimates the land
contained 40,000 tons of ore. During the
first year of operations Apex extracted
and sold 13,000 tons of ore.

$25 per ton × 13,000 Tons = $325,000
Step 1:

29. Machine hour rate method
This is also known as service hour method. This
method take into account the running time of
the asset for the purpose of calculate
depreciation.
Original cost of asset - Scrape value
Estimate life(in hour)

32. Declining Method
Types of declining method.
1. Reducing installment method
2. Sum of Year digit method
3. Double declining method
33. Reducing Balance method
• Under this method depreciation is calculated
on the book value.
• It is also known as Diminishing balance.
On next page you will see its example.
34. Book Value:-
Remaining life of an asset is
known as Book Value.

36. This method is on the pattern of
diminishing balance method the amount of
depreciation to be charged to the profit or
loss account under this method
depreciation decrease every year.
37. Formula of (SYD)
Depreciaton = Remaining life of asset(including current year) x Original cost
Sum of All digit(Estimatted life)
38. Example
i. Cost of machinery = Rs 10000
ii. Effective Working life = 3 year
iii. Depreciation =3 year
1st year depreciation = (3 x 10000) / 1+2+3
= 5000
2nd year depreciation= (2x10000) / 6
= 3333
3rd year depreciation= (1x 10000) / 6
= 1667

41. Decreasing annual depreciation expense over the
asset’s useful life.
Double-Declining-Balance
Depreciation
SO 3 Compute periodic depreciation using different methods.
Declining-balance rate
is double the straight-
line rate.
Rate applied to book
value (cost less
accumulated
depreciation).

42. Example
Cost of plant= 117900
Estimated life= 5year
Scarp value= 12900
Straight line
Depreciation= Original cost – Scrap value
Estimated life
= 117900 – Scrap value
