Accumulated depreciation is a permanent account in accounting, which means it's never closed or reset at the end of an accounting period. This is in contrast to temporary accounts, which are closed and reset at the end of each period.
Accumulated depreciation is a contra-asset account that represents the total amount of depreciation expense that has been accumulated over time. It's a key component of a company's balance sheet, and it's used to calculate the net book value of an asset.
As a permanent account, accumulated depreciation is not affected by the accounting period, and it continues to grow over time as depreciation expenses are recorded. This means that the account is always increasing, and it provides a historical record of the depreciation that has occurred on an asset.
The balance in the accumulated depreciation account is also reflected in the asset's carrying value, which is the asset's value on the balance sheet.

What Is Accumulated Depreciation?

Accumulated Depreciation is a balance sheet contra asset account that is not closed at the end of each accounting period, making it a permanent account.
It's recorded in the general ledger as a permanent account, unlike Depreciation Expense which is a temporary account.
Accumulated Depreciation is used to track the total amount of depreciation that has been recorded for an asset over its useful life.
The balance of Accumulated Depreciation is not zeroed out at the end of each accounting year, unlike Depreciation Expense.
This means that the balance of Accumulated Depreciation will grow over time as more depreciation is recorded.
Here are some key characteristics of Accumulated Depreciation:
- It's a balance sheet account
- It's a contra asset account
- It's not closed at the end of each accounting period
- It's a permanent account
Accumulated Depreciation is used to reduce the carrying value of an asset on the balance sheet, reflecting its decreasing value over time.
For example, if a company has equipment with a cost of $600,000 and an estimated useful life of 10 years, the monthly depreciation will be $5,000 per month, and the Accumulated Depreciation will grow by $5,000 each month.

Types of Accounts
There are two main types of accounts: permanent and nominal accounts. Permanent accounts have cumulative balances that increase or decrease over time, whereas nominal accounts are closed at the end of each accounting period.
Permanent accounts are also known as real accounts and make up the Assets, Liabilities, and Owner's Equity accounts of the Balance Sheet, except for a Drawing Account. They represent the actual worth of the company at a specific point in time.
For example, Fixed Assets have a balance of $600,000 at the end of 2019, which increases to $720,000 by the end of 2020 after purchasing additional assets.

Permanent Accounts
Permanent accounts are the accounts that are reported in the balance sheet. They include asset accounts, liability accounts, and capital accounts.
Asset accounts such as Cash, Accounts Receivable, and Inventories are all permanent accounts. Contra-asset accounts like Allowance for Bad Debts and Accumulated Depreciation are also permanent accounts.

Liability accounts like Accounts Payable, Notes Payable, and Loans Payable are permanent accounts. These accounts are not closed at the end of the accounting period, so their balances are carried forward to the next year.
The balance of a permanent account is cumulative, meaning it increases or decreases over time. For example, if a company had a balance of $100,000 in Cash at the end of 2020, that amount would be carried onto 2021 as the beginning balance.
Permanent accounts are not closed into capital at the end of the accounting period like temporary accounts are. Instead, their balances are carried forward to the next year, allowing users to see the cumulative effect of transactions over time.
The balance of a permanent account can be increased or decreased over time. For example, if a company purchased additional fixed assets in the amount of $120,000, the total Fixed Assets balance would increase to $720,000.

What Is a Permanent Account?

A Permanent Account is an account with a balance that carries over to the next business period, never closed in the books.
These accounts, also known as real accounts, make up the Assets, Liabilities, and Owner's Equity accounts of the Balance Sheet, with the exception of a Drawing Account.
The beginning balance of a Permanent Account is the ending balance of the last accounting period, unlike nominal accounts that start at zero in the next accounting period.
Permanent Accounts represent the actual worth of the company at a specific point in time, which is why accountants review them to ensure accuracy.
Having too many Permanent Accounts can pose more work for accountants to monitor over time, so it's essential to review the need for new accounts or combining existing ones.
Permanent Accounts are found in the Balance Sheet, except for a Drawing Account, which is closed against capital at year-end.
