Depreciation is a non-cash expense that reduces the value of an asset over its useful life.
It's calculated by dividing the asset's cost by its useful life, which can be expressed in years or units of production.
The asset's value is then reduced by this amount each period, resulting in a loss on the income statement.
This loss is a legitimate expense that reflects the asset's decreasing value and is a key component of accrual accounting.

Accumulated Depreciation
Accumulated depreciation is a contra account that reduces the value of a company's fixed assets. It's recorded on the general ledger as a credit and under the assets section of the balance sheet.
Accumulated depreciation increases over time as depreciation expenses are recorded each year. The total amount of depreciation expense recorded for an asset is calculated by summing up the depreciation expense amounts for each year up to that point.
As an asset is eventually sold or retired, its accumulated depreciation is removed from the balance sheet, reducing its value to $0.

What Is Accumulated

Accumulated depreciation is a record of all depreciation expenses for a particular asset as of a certain point in time. It's a running total that increases over time as more depreciation expenses are recorded.
Accumulated depreciation is recorded as a contra account on a company's general ledger, and it's listed as a credit under the assets section of the balance sheet. This reduces the value of the company's fixed assets.
As an asset is used, its value decreases, and the accumulated depreciation associated with it increases. This is because depreciation expenses are recorded each period, reflecting the asset's declining value.
Accumulated depreciation is removed from the balance sheet when an asset is sold or retired, reducing its value to $0.

Accumulated Depreciation Example
Accumulated depreciation is calculated by summing up the depreciation expense amounts for each year up to that point.
A company spent $25,000 for a piece of equipment with a salvage value of $2,000 and a useful life of five years. The depreciation expense per year would be $4,600.

The accumulated depreciation for the asset would be $4,600 for the first year and grow by another $4,600 in each subsequent year, totaling $18,400 after four years.
Accumulated depreciation grows by the same amount each year as the depreciation expense.
This means that after five years, the accumulated depreciation would be $23,000, which is the total depreciation expense recorded for the asset.

Depreciation Calculation
Depreciation expense can be calculated using the straight-line method, which is the simplest way to do it.
The formula for the straight-line method is (cost of asset minus salvage value) divided by useful life. This formula helps spread the cost of the asset over its useful life.
For example, if a company spent $25,000 for a piece of equipment with a salvage value of $2,000 and a useful life of five years, the depreciation expense per year would be $4,600.
Accumulated depreciation grows by the same amount each year, so after four years, the total accumulated depreciation would be $18,400.

The Internal Revenue Service (IRS) requires businesses to depreciate and deduct the cost of many assets over a set number of years, rather than allowing them to fully deduct the cost in the year of purchase.
This helps avoid distorting a company's profit picture for that year by writing off a large capital cost all at once.
Depreciation Types
There are two main types of property depreciation expenses. Capital works depreciation covers the building structure, while plant and equipment depreciation covers assets within the building, such as furniture, appliances, and fittings.
Capital works depreciation is covered under Division 43.
Plant and equipment depreciation, on the other hand, falls under Division 40.

Depreciation vs. Other Expenses
Depreciation is a unique type of expense that doesn't require you to spend money to claim it.
Unlike other expenses, depreciation is a non-cash deduction that allows property owners to offset the cost of owning an investment property against their taxable income.

This means you can reduce the amount of tax you need to pay without exchanging money with anyone, which is a big advantage for property investors.
Depreciation is also a non-cash expense for businesses, which is recognized on the income statement as a reduction in net income or profit.
For accounting purposes, depreciation expense is debited while accumulated depreciation is credited, making it a distinct type of expense from other cash transactions.

Depreciation Accounting
Depreciation is a non-cash expense that appears on the income statement, but it's not a direct payment to anyone.
It's calculated as the difference between the asset's cost and its residual value, which is its value at the end of its useful life.
Assets like buildings and equipment have a limited lifespan and lose value over time due to wear and tear, making depreciation a necessary accounting entry.

The straight-line method is a common way to calculate depreciation, where the asset's cost is divided by its useful life to determine the annual depreciation expense.
For example, if a company buys a machine for $10,000 with a useful life of 5 years, the annual depreciation expense would be $2,000.
Depreciation is also recorded as a decrease in the asset's value on the balance sheet, which is why it's often referred to as a "non-cash" expense.
As assets become old and worn out, their value decreases, and this decrease is reflected in the company's financial statements through depreciation.

Suggestion: Why Land Not Depreciated

As an example, let's say you purchase a piece of equipment for $10,000. Over the next few years, its value decreases due to wear and tear, and you're left with a loss of $3,000. This loss can be claimed on your taxes as depreciation.
In the eyes of the IRS, depreciation is a way to match the costs of using an asset with the revenues it generates. This is known as the matching principle.
