Depreciation Expense Formula + Calculation Tutorial

The double-declining-balance method, or reducing balance method,9 is used to calculate an asset’s accelerated rate of depreciation against its non-depreciated balance during earlier years of assets useful life. Depreciation ceases when either the salvage value or the end of the asset’s useful life is reached. But in practice, most companies prefer straight-line depreciation for GAAP reporting purposes because lower depreciation will be recorded in the earlier years of the asset’s useful life than under accelerated depreciation. The expected useful life is another area where a change would impact depreciation, the bottom line, and the balance sheet.

Diminishing balance method

Depreciation measures the value an asset loses over time—directly from ongoing use (through wear and tear) and indirectly from the introduction of new product models (plus factors such as inflation). Writing off only a portion of the cost each year, rather than all at once, also allows businesses to report higher net income in the year of purchase than they would otherwise. The sum-of-the-years’ digits (SYD) method also allows for accelerated depreciation.

1. The balance in the Equipment account will be reported on the company’s balance sheet under the asset heading property, plant and equipment.
2. Estimated useful life is the number of years of service the business expects to receive from the asset.
3. Learn financial statement modeling, DCF, M&A, LBO, Comps and Excel shortcuts.
4. To calculate depreciation expense, multiply the result by the same total historical cost.
5. Instead of recording an asset’s entire expense when it’s first bought, depreciation distributes the expense over multiple years.

Modified Accelerated Cost Recovery System (MACRS)

Sandra’s areas of focus include advising real estate agents, brokers, and investors. She supports small businesses in growing to their first six figures and beyond. Alongside her accounting practice, Sandra is a Money and Life Coach for women in business. Inverse year number is the first year of expected life, starting from the greatest digit, divided by the total years. Divide this by the estimated useful life in years to get the amount your asset will depreciate every year.

In the end, the sum of accumulated depreciation and scrap value equals the original cost. For mature businesses experiencing low, stagnating, or declining growth, the depreciation to capex ratio converges near 100%, as the majority of total Capex is related to maintenance Capex. In turn, depreciation can be projected as a percentage of Capex (or as a percentage of revenue, with depreciation as an % of Capex calculated separately as a sanity check).

If the data is readily accessible (e.g., a portfolio company of a private equity firm), then this granular approach would be feasible, as well as be more informative than the simple percentage-based projection approach. While more technical and complex, the waterfall approach seldom yields a substantially differing result compared to projecting Capex as a percentage of revenue and depreciation as a percentage of Capex.

The two main assumptions built into the depreciation amount are the expected useful life and the salvage value.

Suppose that the company is using the straight-line schedule originally described. After three years, the company changes the expected useful life to a total of 15 years but keeps the salvage value the same. With a book value of $73,000 at this point (one does not go back and “correct” the depreciation applied so far when changing assumptions), there is $63,000 left to depreciate. This will be done over the next 12 years (15-year lifetime minus three years already). The above example uses the straight-line method of depreciation and not an accelerated depreciation method, which records a larger depreciation expense during the earlier years and a smaller expense in later years.

These assets are often described as depreciable assets, fixed assets, plant assets, productive assets, tangible assets, capital assets, and constructed assets. The table below illustrates the units-of-production depreciation schedule of the asset. Therefore, $100k in PP&E was purchased at the end of the initial period (Year 0) and the value of the purchased PP&E on the balance sheet decreases by $20k each year until it reaches zero by the end of its useful life (Year 5). If a manufacturing company were to purchase $100k of PP&E with a useful life estimation of 5 years, then the depreciation expense would be $20k each year under straight-line depreciation. The core objective of the matching principle in accrual accounting is to recognize expenses in the same period as when the coinciding economic benefit was received.
