Depreciation charging difference between 2 & 3 shifts

As far as rate of companies act is concerned rate of Depreciation provided under Schedule XIV are the minimum rates, i.e. if a company thinks so it can use higher rate of Depreciation but it should be a reasonable rate and it should be justifiable ,

In your case difference in rate is not very much, and if there is justification available,  that use of higher rate will show the true picture and it will depreciate the asset within the estimated useful life of the asset than use of higher rate is possible

As far as deprecation while calculating taxable income under Income tax is concerned we are to use the rates mentioned under Income Tax Rules and no other rates are allowed.

Also there was a guidance note issued by ICAI “Guidance Note on Accounting for Depreciation in Companies” you can also refer that guidance note.

Thanks for your reply. I'm asking this from costing point of view. Pls see the below table,

Do u think its still fair to charge depreciation of 10.34%.

As u said the company can charge if its justifiable but I think the difference between single shift & Triple shift Cost/Hr is high.

machine hour = 8*26*12

If you are seeing it from costing point, then you should firstly see what other Companies are doing, after that you should estimate the use full life of your machine under normal circumstances, and then calculate a rate for absorption of depreciation.

Again please note there might be a case where you, to say may estimate the use full life 3 Year (because of bad machine or 2^nd hand machine or any other abnormal reason), but normally that kind of machine can be used for 5 yrs then you should calculate absorption rate accordingly
