Depreciation calculator
How it’s worked out.
The rules the calculator applies, from Schedule II to the Companies Act 2013 and ICAI’s study material.
Depreciation spreads the depreciable amount of an asset, its cost less its residual value, over its useful life.

The useful life should not ordinarily differ from the life in Part C, and the residual value should not be more than 5% of the original cost. A company that uses others must disclose the difference and justify it with technical advice.

Part C sets the useful lives. Some of them: general plant and machinery 15 years, general furniture and fittings 10, cars not run on hire 8, office equipment 5, servers and networks 6, desktops and laptops 3.

An asset added during the year is depreciated pro rata from the date it was added. One sold or discarded is depreciated up to the date it went.

Straight line: the same charge every year, (cost − residual value) ÷ useful life.

Written down value: a fixed rate on each year’s opening book value. The rate that brings the cost down to the residual value over the life is 1 − ⁿ√(residual value ÷ cost), where n is the useful life.

The accounts disclose the depreciation methods used, and any useful life different from the Schedule’s.

One example, step by step.
A machine bought for ₹10,00,000 and put to use on 1 October 2026: general plant and machinery, 15 years, residual value 5% of cost.
- Cost
- ₹10,00,000
- Residual value5% of cost
- ₹50,000
- Depreciable amount
- ₹9,50,000
- Straight line, a full year9,50,000 ÷ 15
- ₹63,333.33
- Days used in FY 2026-271 Oct to 31 Mar
- 182 of 365
- Straight line, FY 2026-27
- ₹31,579.91
- WDV rate1 − ¹⁵√0.05
- 18.10%
- Written down value, FY 2026-2710,00,000 × rate × 182 ÷ 365
- ₹90,270.14
Straight line charges ₹63,333.33 in each full year after that. Both methods end on the ₹50,000 residual value in FY 2041-42.
An illustration, not tax advice. The schedule uses the unrounded WDV rate. Income-tax depreciation is worked out separately.
What it does not cover.
Check these with your CA before you rely on the figures.
Income-tax depreciation
Tax depreciation follows the income-tax law, on blocks of assets at its own rates, not Schedule II’s lives. The calculator works out the books’ depreciation only.
Double and triple shifts
The calculator assumes single-shift working, which is what Part C’s lives are based on.
Used for a double shift, depreciation for that period goes up by 50%; for a triple shift, by 100%. Assets marked NESD get no extra shift depreciation.

Significant parts
A part with its own life, such as a furnace lining, is depreciated on its own. Enter it as a separate asset.
Where a part’s cost is significant to the asset and its life differs from the rest, that part’s useful life is set separately.

Lives set by a regulator
Some sectors, such as power, have lives notified for their assets. Those come first.
A useful life or residual value notified for accounting by a regulator under an Act of Parliament, or by the Central Government, applies instead of the Schedule.

Intangible assets
Software licences, trademarks and other intangibles follow the accounting standards, not Part C.
For intangible assets, the Indian Accounting Standards apply, or the Accounting Standards for a company not on Ind AS.

Sales, revaluation and impairment
The calculator follows one asset from the day it was added. It does not work out the profit or loss on a sale, a revaluation or an impairment.

Depreciation questions people ask.
How is depreciation calculated under the Companies Act 2013?
Schedule II spreads the cost of an asset, less its residual value, over its useful life. Part C gives the useful lives, and the residual value is ordinarily no more than 5% of cost. The company picks a method, usually straight line or written down value.
What is the WDV rate for a useful life?
The rate that takes the cost down to the residual value over the life: 1 − ⁿ√(residual ÷ cost), where n is the life in years. With a residual value of 5% of cost, a 15-year life gives 18.10%, and a 5-year life gives 45.07%.
What is the useful life of a computer under Schedule II?
Three years for desktops, laptops and other end-user devices, and six years for servers and networks.
Is depreciation charged for the full year on an asset bought mid-year?
No. Schedule II charges it pro rata from the date the asset was added. The calculator counts the days from that date to 31 March, or the months if you choose.
Can a company use a different useful life or a higher residual value?
Yes, with technical advice to back it. The financial statements must disclose the difference and the reason for it.
Are these the rates for income tax?
No. Income-tax depreciation is worked out separately, on blocks of assets at the rates in the income-tax law. Ask your CA for that figure.
Does it handle double-shift working?
No. The calculator assumes single-shift working. Under Schedule II, depreciation goes up by 50% for a period of double-shift use and by 100% for triple shift, except for assets marked NESD.
Is what I type saved or sent anywhere?
No. The figures are worked out in your browser. Nothing is sent, stored or tracked by the calculator.
