Depreciation Calculator FAQs

Clear answers to common questions about straight line depreciation in India.

What is Straight Line Depreciation?

Straight Line Depreciation is a method where the cost of an asset, after deducting residual value, is spread equally over its useful life. For example, if an asset costs ₹1,00,000, has a residual value of ₹5,000, and useful life of 5 years, annual depreciation is ₹19,000.

Is Straight Line Method allowed under Indian income tax law?

For most Indian income-tax cases, depreciation is calculated using the Written Down Value method on prescribed block-of-asset rates. Straight Line Method may be relevant for specific eligible undertakings or for book/accounting depreciation. Always verify with a CA or tax expert before filing.

Residual value, also called salvage value, is the estimated value of an asset at the end of its useful life. It is deducted from the original cost before calculating straight line depreciation.
