Companies Act Schedule II focuses on systematic allocation of an asset’s depreciable amount over the useful life in the financial statements. Income-tax WDV blocks are different and should be maintained separately. The chosen depreciation method, component lives and salvage estimate should reflect the asset’s consumption pattern and the accounting policy.
For cost of ₹10 lakh, residual value ₹50,000 and useful life of ten years, the straight-line full-year expense is ₹95,000. A WDV rate designed to reduce ₹10 lakh to ₹50,000 in ten full years is one minus the tenth root of 50,000 divided by 10,00,000. The engine derives that rate rather than using an income-tax rate table.
An asset bought in June but commissioned in October should generally start depreciating when available for use according to the accounting policy. This workbook apportions first and final fiscal periods by days, with a complete annual rate for full financial years. It ends at the selected useful-life date rather than always charging a full extra final year.
Schedule II includes different prescribed useful lives for buildings, computers, plant classes and other assets. Component accounting, changes in estimates, residual values, impairment, disposals, regulatory lives and technical justification can change the result. The user must verify the appropriate life and disclosure before relying on the output.
Schedule II says the residual value should not normally exceed 5% of the original cost unless justified. The calculator accepts any residual below cost, so keep to your policy.
Depreciation starts when the asset is available for use, so the first financial year is charged only for the days remaining after that date.
No. Tax depreciation under the Income-tax Act uses separate eligibility and block rates.
