Accumulated Depreciation: Definition, Formula, Journal Entries & Examples

What Is Accumulated Depreciation?

When you buy a fixed asset — a machine, a truck, office furniture — you do not write off the entire cost in the year of purchase. Instead, you spread it over the asset's useful life as a depreciation expense. But here is the question students often miss: where does all that depreciation accumulate on the balance sheet?

The answer is the accumulated depreciation account. It is a running total — a growing credit balance that records every single depreciation charge made on an asset since the day it was purchased. By the time an asset reaches the end of its useful life, the accumulated depreciation equals the total amount depreciated (i.e., Cost minus Salvage Value).

Think of it this way. If a machine costs ₹5,00,000 and you charge ₹50,000 depreciation every year, after Year 3 the accumulated depreciation is ₹1,50,000. The machine still sits in your books at ₹5,00,000 (gross cost), but its net book value (carrying amount) is only ₹3,50,000. Accumulated depreciation is the bridge between gross cost and what the asset is actually worth on paper.

Crucially, accumulated depreciation is a contra-asset account. It has a credit balance — the opposite of the debit balance of the fixed asset account it offsets. This is why it is shown as a deduction on the balance sheet under Property, Plant and Equipment (PPE) or Fixed Assets.

Accumulated Depreciation: Formula

There are two ways to calculate accumulated depreciation, depending on what information you have.

Key terms:

• Cost of Asset — the original purchase price plus all costs to bring the asset into use (freight, installation, trial runs)
• Annual Depreciation Expense — calculated using SLM, WDV, or units of production method
• Net Book Value (NBV) — also called carrying amount; it is what the asset is worth on paper today: Cost − Accumulated Depreciation
• Number of Years Used — only applies when using the straight line method (SLM), where the annual charge is constant

Journal Entry for Accumulated Depreciation

Every year, a journal entry is passed to record depreciation. There are two methods:

Method 1: Provision for Depreciation Account (Preferred under Ind AS)

The Accumulated Depreciation A/c grows every year. The asset account remains at its original cost. The NBV shown on the balance sheet = Gross Cost − Accumulated Depreciation.

Method 2: Charging Directly to Asset Account (Old method, still used in some textbooks)

Under Method 2, no separate accumulated depreciation account is maintained. The asset account is directly reduced each year. Method 1 is superior because it preserves the original cost for transparency and audit purposes. Under Ind AS 16 and IAS 16, Method 1 is required.

How Accumulated Depreciation Appears on the Balance Sheet

This is where many students get confused—because accumulated depreciation is not shown as a standalone figure in most financial statements. Instead, it is presented as a deduction from the gross cost of the asset.

Here is how it looks in a typical balance sheet extract under Non-Current Assets / Fixed Assets:

The gross cost stays fixed (₹5,00,000) as long as the asset is owned. The accumulated depreciation grows every year. The difference—the net book value—shrinks to zero (or to salvage value) by the end of the asset's life.

Depreciation Expense vs Accumulated Depreciation: The Key Difference

This is the single most common exam question on this topic—and it is actually very logical once you see it clearly.

In plain language: Depreciation expense is the slice you cut this year. Accumulated depreciation is the whole slice of pie you have cut so far. The journal entry that links them every year:

Depreciation expense hits the P&L this year and is gone. The accumulated depreciation credit stays on the balance sheet, growing bigger every year until the asset is fully depreciated or disposed of.

Accumulated Depreciation on Asset Disposal

When a business sells or scraps a fixed asset, the accumulated depreciation account does not just disappear—it gets cleared out along with the original cost. Here is exactly what happens, step by step.

The Disposal Journal Entry

Suppose a machine was purchased for ₹8,00,000, has accumulated depreciation of ₹5,50,000, and is sold for ₹3,20,000 cash.

Step 1 — Net Book Value: ₹8,00,000 − ₹5,50,000 = ₹2,50,000

Step 2 — Profit on Disposal: ₹3,20,000 − ₹2,50,000 = ₹70,000 profit

If the sale proceeds were less than the net book value—say ₹2,00,000—there would be a loss on disposal of ₹50,000, which would appear on the debit side.

What If an Asset Is Fully Depreciated but Still in Use?

Sometimes a machine reaches zero net book value but the business still uses it. In that case, you simply stop charging depreciation—you cannot depreciate below zero or below salvage value. The asset remains in the balance sheet at cost with accumulated depreciation equal to the depreciable amount (cost minus salvage value) until it is physically disposed of.

Accumulated depreciation does not exist in isolation. It connects closely to several other accounting topics. Explore our in-depth guides below to build a complete picture:

• Units of Production Method of Depreciation — How depreciation and accumulated depreciation build up based on actual usage rather than time.
• Trial Balance — Accumulated depreciation appears as a credit balance in the trial balance. Learn how to classify it correctly.
• Accrual Accounting — The accrual concept is why we spread asset costs over useful life rather than expensing them immediately.

Frequently Asked Questions on Accumulated Depreciation

Is accumulated depreciation an asset or a liability?

Neither—it is a contra-asset. It has a credit balance and is shown as a deduction from the gross cost of the fixed asset on the balance sheet. This reduces the net book value of the asset without creating a liability.

Can accumulated depreciation exceed the cost of an asset?

No. Accumulated depreciation can never exceed the depreciable amount, which is the cost of the asset minus its salvage (residual) value. Once the asset is fully depreciated to its salvage value, you stop recording depreciation.

What is the normal balance of accumulated depreciation?

The normal balance of accumulated depreciation is a credit. Every year, you credit accumulated depreciation and debit depreciation expense. The credit balance grows over the asset's life. This is why it is called a contra-asset—it has the opposite normal balance from regular asset accounts (which have debit balances).

How does accumulated depreciation affect cash flow?

Accumulated depreciation itself does not directly involve cash. However, depreciation expense (which builds up accumulated depreciation) is a non-cash expense. In the cash flow statement under the indirect method, depreciation expense is added back to net profit to arrive at cash from operations, because it was deducted in the P&L but did not involve an actual cash outflow.

Is accumulated depreciation shown in the trial balance?

Yes. Accumulated depreciation appears in the trial balance as a credit balance. It is often listed separately from the fixed asset account (which has a debit balance). When preparing the balance sheet from the trial balance, you present the net of these two—the net book value. Check our trial balance guide for worked examples.

What happens to accumulated depreciation when an asset is revalued?

Under IAS 16 and Ind AS 16, when a fixed asset is revalued, accumulated depreciation may be either (a) restated proportionately so the carrying amount equals the revalued amount, or (b) eliminated against the gross carrying amount, with the net amount restated to the revalued amount. The method used must be consistent.
