Our experts love this top pick, which features a 0% intro APR until 2024, an insane cash back rate of up to 5%, and all somehow for no annual fee. Other assets lose their value in a steady manner (furniture or real estate are good examples), so it makes more sense to use straight-line depreciation in these cases. Calculating straight line depreciation is a five-step process, with a sixth step added if you’re expensing depreciation monthly. Note that the straight depreciation calculations should always start with 1. Every ten years, Jason buys a new automatic car washing machine to ensure that his customers have access to quality equipment.

However, the projected useful lifetime of the asset is an estimate that can throw off the calculation over time. For example, the value of technology can sometimes deteriorate more rapidly than expected. If you want to take the equation a step further, you can divide the annual depreciation expense by twelve to determine monthly depreciation. This step is optional, however, it can shed light on monthly depreciation expenses. This means taking the asset’s worth (the salvage value subtracted from the purchase price) and dividing it by its useful life. First and foremost, you need to calculate the cost of the depreciable asset you are calculating straight-line depreciation for.

What is Straight Line Depreciation?

Below, we’ve provided you with some straight line depreciation examples. This means Sara will depreciate her copier at a rate of 20% per year. The easiest way to determine the useful life of an asset is to refer to the IRS tables, which are found in Publication 946, referenced above.

Therefore, Company A would depreciate the machine at the amount of $16,000 annually for 5 years.

What are Other Types of Depreciation Methods?

In this example, the depreciation rate can also be specified in terms of a percentage. This example calculates the depreciation expense for an asset (see table below) using the straight-line method. Straight-line depreciation is widely used due to its simplicity and the fact that it allocates an equal amount of expense to each period of the asset’s life. To illustrate how to calculate partial year’s depreciation, assume that in the above example, the asset was purchased on 1 April rather than on 2 January. However, in the real world, companies purchase assets at different times during the year, and a full year’s depreciation need not be taken on a partial year’s usage.

Where is straight line equation used?

The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept. It is the most common form of the equation of a straight line that is used in geometry.

In other words, companies can stretch the cost of assets over many different time frames, which lets them benefit from the asset without deducting the full cost from net income (NI). You can use the straight-line depreciation method to keep an eye on the value of your fixed assets and predict your expenses for the next month, quarter, or year. If your company uses a piece of equipment, you should see more depreciation when you use the machinery to produce more units of a commodity. If production declines, this method lowers the depreciation expenses from one year to the next. You can use this method to anticipate the cost and value of assets like land, vehicles and machinery.

Straight Line Depreciation

Depreciation generally applies to an entity’s owned fixed assets or to its leased right-of-use assets arising from lessee finance leases. You would also credit a special kind of asset account called an accumulated depreciation account. These accounts have credit balance (when an asset has a credit balance, it’s like it has a ‘negative’ balance) meaning that they decrease the value of your assets as they increase. A fixed asset account is reduced when paired with accumulated depreciation as it is a contra asset account. The other popular methods used in calculating depreciation value are; Sum of years method or unit of production method and double declining balance method.

  • According to straight-line depreciation, this is how much depreciation you have to subtract from the value of an asset each year to know its book value.
  • Accumulated depreciation is eliminated from the accounting records when a fixed asset is disposed of.
  • With straight-line depreciation, you must assign a “salvage value” to the asset you are depreciating.
  • Straight-line depreciation is an accounting method that measures the depreciation of a fixed asset over time.
  • It calculates how much a specific asset depreciates in one year, and then depreciates the asset by that amount every year after that.
  • For example, there is always a risk that technological advancements could potentially render the asset obsolete earlier than expected.
  • The annual depreciation expense would be calculated by dividing the depreciable basis ($100,000) by the useful life (20 years), resulting in an annual depreciation expense of $5,000.

The IRS has categorized depreciable assets into several property classes. These classes include properties that depreciate over three, five, ten, fifteen, twenty, and twenty-five years. According to straight line depreciation, the company machinery will depreciate $500 every year.

Step 5: Divide by 12 for monthly depreciation (optional)

When keeping your company accounting records, straight line depreciation can be recorded on the depreciation expense account as debit and credit on the accumulated depreciation account. Accountants use the straight line depreciation method because it is the easiest to compute and can be applied to all long-term assets. However, the straight line method does not accurately reflect the difference in usage of an asset and may not be the most appropriate value calculation method for some depreciable assets. With the straight line depreciation method, the value of an asset is reduced uniformly over each period until it reaches its salvage value.

  • The Ascent is a Motley Fool service that rates and reviews essential products for your everyday money matters.
  • This is then divided by the estimated projected useful lifetime of the asset.
  • Straight-line depreciation grants a paper loss of a set percentage each year over the useful life of the property.
  • The straight-line method of depreciation assumes a constant rate of depreciation.
  • The straight line method of depreciation is one way of calculating this value.
  • An asset with a $20,000 cost and a $10,000 salvage value has a useful life of 10 years.

Before you can calculate depreciation of any kind, you must first determine the useful life of the asset you wish to depreciate. With this cancellation, the copier’s annual depreciation expense would be $1320. Using the straight-line method, an asset’s value is depreciated uniformly over its useful life, while a declining balance approach allocates more Depreciation in the early years than in the late years. Also, since the asset had an estimated useful life of 10 years, the depreciation expense each year was 1/10 of the depreciable amount. Under the straight-line method, the depreciable basis is divided by the number of years in the asset’s life in order to determine the average annual expense.

Accumulated depreciation is a contra asset account, which means that it is paired with and reduces the fixed asset account. Accumulated depreciation is eliminated from the accounting records when a fixed asset is disposed of. The straight line method of depreciation is also useful for taxes and write-offs.

This method is useful for businesses that have significant year-to-year fluctuations in production. This number will show you how much money the asset is ultimately worth while calculating its depreciation. Now that you have calculated the purchase price, life span and salvage value, it’s time to subtract these figures.

The straight-line depreciation method is a simple and reliable way small business owners can calculate depreciation. The straight-line depreciation method is important because you can use the formula to determine how much value an asset loses over time. By using this formula, you can calculate when you will need to replace an asset and prepare for that expense. There are good reasons for using both of these methods, and the right one depends on the asset type in question. The straight-line depreciation method is the easiest to use, so it makes for simplified accounting calculations. For example, let’s say that you buy new computers for your business at an initial cost of $12,000, and you depreciate their value at 25% per year.

straight line method formula

The cost of an asset is the amount that was paid to purchase it, while the salvage value is the estimated value of the asset at the end of its useful life. The useful life of an asset refers to the total amount of time that it can be used before being replaced or retired. Using the formula to calculate these figures provides the annual depreciation expense, which is a measure of the amount by which an asset’s value declines each year. Straight line depreciation is used to calculate the depreciation, or loss of value over time, of fixed assets that will gradually lose their value. The declining balance method of depreciation does not recognize depreciation expense evenly over the life of the asset. Rather, it takes into account that assets are generally more productive the newer they are and become less productive in their later years.
