Amortisation meaning in simple words: writing off intangibles

The Plainomics desk2 sources

Amortisation: the cost of something you can't touch, like software or a licence, spread across the years it is useful.

At the stall, Riya holds up her phone to show Sameer the new ordering app while he rubs his chin.

The story

two people, one chai stall

Riya shows Sameer the new ordering app on her phone. It cost ₹2.5 crore to build.

Sameer

₹2.5 crore for an app! Did that wipe out a big chunk of this year's profit?

Riya

Only ₹50 lakh of it. We expect the app to be useful for five years, so we spread the cost: ₹0.5 crore a year. That's amortisation.

Sameer

Isn't that just depreciation?

Riya

Same idea, different word. Depreciation is for things you can touch, like kettles. Amortisation is for things you can't, like software, licences or brand rights.

Sameer

Why five years? It's code. It doesn't rust.

Riya

No, but it goes out of date. Phones change and customers expect new features. Five years is our best guess, and we review it every year.

Sameer

Where do I see it?

Riya

The P&L bundles them: depreciation and amortisation, ₹4 crore. ₹3.5 crore for the kiosks and vans, ₹0.5 crore for the app.

Sameer

So the app quietly costs us ₹50 lakh of profit a year.

Riya

For five years. By then we'll probably be building version two.

The grown-up version

same idea, exact words

Amortisation is the systematic allocation of the depreciable amount of an intangible asset with a finite useful life over that life. Under Ind AS 38 it begins when the asset is available for use, and the method should reflect the pattern in which the benefits are consumed; if that pattern cannot be determined reliably, the straight-line method is used. The period and method are reviewed at least at each financial year-end. Intangible assets with an indefinite useful life, and goodwill, are not amortised but tested for impairment.

Formula

Yearly amortisation (straight line) = (Cost − Residual value) ÷ Useful life. For most intangibles the residual value is nil.

Which rule asks for itInd AS 38, Intangible Assets; Schedule II, Companies Act, 2013 (which leaves intangible assets to the accounting standards).

  1. Intangibles with a limited life are written off in equal yearly slices.
  2. ITC writes off computer software over 3 to 5 years.

Don't mix it up

the usual confusions

  • Amortisation ≠ depreciation

    Same idea, different asset. Depreciation is for things you can touch, like kettles and vans. Amortisation is for things you can't, like software and licences.

  • Amortisation ≠ loan amortisation

    Paying off a loan in instalments, like an EMI, is also called amortising it. That's about repaying debt, not spreading an asset's cost.

  • Amortisation ≠ amortised cost

    A way of valuing loans and bonds on the balance sheet. It has nothing to do with wearing out software.
