1. Straight Line method:-
| Year | 1987 | 1988 | 1989 | 1990 | 1991 | 1992 |
| Cost in beginning | 140000 | 126000 | 112000 | 98000 | 84000 | 70000 |
| Depreciation | 14000 | 14000 | 14000 | 14000 | 14000 | 14000 |
| BV at end | 126000 | 112000 | 98000 | 84000 | 70000 | 56000 |
| Cumulative depreciation | 84000 | |||||
| Depreciation of 6th year | 14000 | |||||
| Book value at end of 6th year | 56000 |
2. Declining Balance Method:-
| Depreciation Rate= 1/ No of years | 10% | |||||
| Year | 1987 | 1988 | 1989 | 1990 | 1991 | 1992 |
| Cost in beginning | 140000 | 126000 | 113400 | 102060 | 91854 | 82668.6 |
| Depreciation | 14000 | 12600 | 11340 | 10206 | 9185.4 | 8266.86 |
| BV at end | 126000 | 113400 | 102060 | 91854 | 82668.6 | 74401.74 |
| Cumulative depreciation | 65598.26 | |||||
| Depreciation of 6th year | 8266.86 | |||||
| Book value at end of 6th year | 74401.74 |
3. Sinking Fund Depreciation=
Annual Depreciation= [ (FC -V) (i) ] / [ (1 + i)^(n) -1 ]
= [(140000-0)*(0.08)]/[(1+.08)^10-1]
A = 12943.03
Cumulative depreciation= A[(1 + i)^x - 1] / i
= (12943.03)[(1.08)^6-1]/0.08
= 94949.14
Book value at end of 6th year= 140000-94949.14
= 45050.86

.5. Service output method :-
Depreciation per hour= FC-SV/ Total no of hours
= 140000/10000
=14 per hour
Cumulative depreciation till 6th year= 14*6400
= 102400
Annual depreciation of 6th year= 14*600
= 8400
BV at 6th year= 140000-102400
= 37600
