Accumulated Depreciation: Meaning, Formula, and Practical Example
Quick Summary
- Accumulated depreciation is the total depreciation recorded for an asset since it was bought, reducing its book value.
- It is a contra-asset account, appearing on the asset side of the balance sheet but with a credit balance.
- The accumulated depreciation formula is: (Cost of Asset – Salvage Value) × Number of Years Used / Useful Life.
- A practical example shows that a delivery van bought for ₹5,00,000 with a 5-year life and ₹50,000 salvage value has ₹2,70,000 accumulated depreciation after 3 years.
- Tracking accumulated depreciation is crucial for accurate asset valuation, better decision-making, tax compliance, and audit readiness.
Every fixed asset a business owns, like machines, vehicles, or furniture, loses value over time. This drop in value is called depreciation. But how do we track an asset's total depreciation over the years? That’s where accumulated depreciation comes in.
In this blog, we’ll define accumulated depreciation, explain the accumulated depreciation formula, discuss its account type, and show you a practical example to make it all clear.

Definition of Accumulated Depreciation
Accumulated depreciation is the total amount of depreciation recorded against an asset since it was purchased. It is not a one-time entry but rather a running total of all depreciation expenses recorded over the asset’s life.
If a business has been depreciating a machine for 3 years at ₹10,000 per year, the accumulated depreciation at the end of year 3 would be ₹30,000.
This amount is subtracted from the asset’s original cost to calculate its book value or what it’s currently worth on paper.
Why is the Accumulated Depreciation important?
Understanding and tracking accumulated depreciation is essential for:
- Accurate asset valuation – Shows true book value
- Better decision-making – Know when to replace or upgrade assets
- Tax compliance – Required for claiming depreciation benefits
Audit readiness – Clear financial reporting supports audits
What is Accumulated Depreciation Account Type?
Now, you may wonder, what type of account is accumulated depreciation? It is a contra-asset account. That means it appears on the asset side of the balance sheet but carries a credit balance. It reduces the total value of fixed assets, helping businesses reflect the assets' actual value after depreciation.
| Item | Value (₹) |
|---|---|
| Original Cost of Machinery | 1,00,000 |
| Accumulated Depreciation | 40,000 |
| Net Book Value | 60,000 |
Although it appears with assets, the accumulated depreciation account works like a liability because it holds a credit balance.

Accumulated Depreciation Formula
The formula to calculate accumulated depreciation is as simple as it mainly depends on the depreciation method you choose. The most common one is the straight-line method .
Accumulated Depreciation = (Cost of Asset – Salvage Value) × Number of Years Used / Useful Life
Where:
- Cost of Asset is the original purchase price
- Salvage Value is the estimated value at the end of its useful life
- Useful Life is the expected life span of the asset
Example of Accumulated Depreciation
Let’s say a company purchases a delivery van for ₹5,00,000. The van is expected to have a useful life of 5 years and a salvage value of ₹50,000.
Step 1: Calculate annual depreciation
₹(5,00,000 – 50,000) / 5 = ₹90,000
Step 2: After 3 years, accumulated depreciation = ₹90,000 × 3 = ₹2,70,000
Net book value after 3 years = ₹5,00,000 – ₹2,70,000 = ₹2,30,000
This amount will be shown under accumulated depreciation in the books, thereby reducing the asset's value.
