How should I calculate depreciation in this case

Gross Block of machinery as on 1/04/2007 ..................................1,00,000

hi suman

u want answer as per income tax act or companies act?

reply me so tht  can answer accordingly

the information provided is not complete.

please tell what is accumlated depriciation till date.?

only machine puchased on 1/2/2008 used for triple shift? or also which was purchased on 1/6/2007?

u want as per company act or income tax act?

Second machine:

 20000*27.82%*2 months= 927

So,total depriciation for year= 1103+695+927=2,725.

If this assumption is wrong,tell me correct information.

this is as per company act.

First apply full year depriciation on WDV as on 01/04/2007,the Gros block of which is 100000 as per ur query.

Then on the machine which purchased on 01/06/2007,apply single shift rate as per companies act till 31/12/2007 for 7 months and then triple shift till 31/03/2008(Assuming that it is used in triple shift after 31/12/2007).

Then on the machinery purchased on 01/02/2008,apply triple shift rate for 2 months till 31/03/2008.

Do see the rates for double and triple shift in Schedule 14 of Company Act. And all the calculation will on proportionate basis for the period for which the asset is used.and that could be in months or days.

This is the answer to ur query as per the information provided by u.

First tell me, u want to calculate depreciation under IT act or companies act.
