Depreciation Accounting for Banks: A CAAP Exam Guide (2026)

Getting depreciation accounting for banks right is one of those quiet exam topics that trips up otherwise well-prepared CAAP candidates — because banks don't follow one neat, universal rate table the way many company-law questions assume. Instead, a bank's depreciation policy is a board-approved mix of AS 10 / Ind AS 16 principles, useful-life estimates, and disclosure requirements that show up directly in Schedule 10 of the balance sheet. This guide walks through the methods, the asset-class nuances, and the audit checks examiners love to test.

🏦 Depreciation Methods Used by Banks (WDV vs SLM)

Banks are free to adopt either the Written Down Value (WDV) method or the Straight Line Method (SLM), but the choice must be applied consistently across an asset class and disclosed as an accounting policy in the notes to accounts. Most public sector banks historically used WDV for premises and SLM for computers and vehicles, purely because WDV front-loads the depreciation charge in the early years of an asset's life — useful when assets are expected to lose utility faster in year one than in year ten. The core chapter on depreciation accounting works through both formulae with worked examples, which is the fastest way to internalise the arithmetic difference before attempting numerical questions in the exam.

A change in method is treated as a change in accounting policy, not an accounting estimate, and must be applied retrospectively with the cumulative effect disclosed separately — a distinction examiners like to test because it is so easily confused with a mere change in useful life (which is prospective only).

💡 Exam Tip: If a question describes a bank switching from WDV to SLM, remember it needs retrospective restatement and disclosure of the resulting surplus or deficit — not just a note for future years.

📉 Asset Classes, Useful Life and Schedule 10 Disclosure

Bank balance sheets present fixed assets under Schedule 10, split broadly into Premises and Other Fixed Assets (furniture, fixtures, vehicles, computers, and computer software). Since RBI does not itself prescribe depreciation rates for banks, the useful life is estimated by the bank's own accounting policy, informed by AS 10 (Accounting for Fixed Assets) or Ind AS 16 for banks migrating to the Ind AS framework, and cross-checked against the residual value and expected economic life of each class. This is exactly the disclosure trail examiners expect you to trace back to the chapter on preparation of final accounts of banks, where Schedule 10 is built up line by line alongside the other balance sheet schedules.

Premises typically carry the longest useful life (often 50-60 years under a straight-line policy), furniture and fixtures a mid-range life of around 10 years, and computers/computer software the shortest — usually 3 years — reflecting rapid technology obsolescence. Leasehold improvements are amortised over the lease term or useful life, whichever is shorter.

🖥️ Depreciation on Computers, Software and the Audit Angle

Because banks now run almost every core function through CBS platforms, computers and computer software form a disproportionately large slice of the fixed-asset schedule relative to their book value — and a disproportionately large slice of exam questions. Application software with an enduring benefit is capitalised and amortised (typically over 3 years), while software that is merely a minor upgrade or an annual licence renewal is expensed. Distinguishing a capitalisable upgrade from a routine licence fee is precisely the kind of judgment call tested under the chapter on audit in computerized environment, since auditors must trace the capitalisation entry back to the vendor invoice and verify it wasn't merely an AMC renewal misclassified as a capital addition.

Auditors performing a bank's concurrent audit in banks routine will typically test a sample of fixed-asset additions each quarter specifically for this misclassification, because it directly inflates reported profit by understating the current year's revenue expense.

⚠️ Common Mistake: Candidates often assume all IT spend is capital expenditure. AMC charges, minor patches, and subscription-based SaaS licences are revenue expenditure and must be expensed in the year incurred.

📊 Revaluation, Capital Reserve and Depreciation Interplay

When a bank revalues its premises upward, the incremental value is credited to a Revaluation Reserve, which sits under Capital Reserve in Schedule 2. From that point on, depreciation must be charged on the revalued (higher) carrying amount, and RBI guidance permits — subject to board policy — transferring an amount equal to the incremental depreciation from the Revaluation Reserve to the Profit & Loss account, so that the P&L is not unfairly burdened by depreciation on a paper revaluation gain. This interaction between the reserves side of the balance sheet and the depreciation charge is covered in depth in the chapter on capital reserves and surplus, and examiners frequently combine a revaluation scenario with a depreciation computation in the same numerical question.

Getting the sequencing right matters: revalue first, then depreciate the revalued figure, then transfer the incremental depreciation portion out of the Revaluation Reserve — doing these steps out of order is the single most common error in practice numericals on this topic.

📌 Remember: Incremental depreciation transferred out of Revaluation Reserve does not reduce the depreciation charge in the P&L — it only offsets the reserve, keeping the P&L charge based on the full revalued cost.

🔍 Audit Checks and Verification of Depreciation

During the statutory audit, the auditor's fixed-asset verification programme for depreciation typically covers: agreeing the opening gross block and accumulated depreciation to the prior year's audited figures, recomputing the current year's charge on a sample of additions and disposals, confirming the depreciation policy note matches what was actually applied, and checking that fully depreciated assets still in active use are appropriately disclosed (even though no further charge is booked). Any change in useful life estimate — as opposed to a change in method — is applied prospectively and simply disclosed, without restating prior years.

These checks sit alongside the broader income-recognition and provisioning review; if you haven't already, revisit the companion guide on income recognition and asset classification norms, since both areas are typically examined by the same statutory audit team in the same audit cycle and often appear together in case-study questions.

Auditors also cross-verify depreciation figures against the bank's own bank reconciliation statement workpapers where fixed-asset-linked suspense entries occasionally surface, particularly around year-end capitalisation cut-offs.
