In the above example, $360,000 worth of PP&E was purchased during the year (which would show up under capital expenditures on the cash flow statement) and $150,000 of depreciation was charged (which would show up on the income statement). The difference between the end-of-year PP&E and the end-of-year accumulated depreciation is $2.4 million, which is the total book value of those assets. Depreciation is a term used to describe the reduction in the value of as asset over a number of years. A Depreciation Schedule is a table that shows the depreciation amount over the span of the asset’s life.

1. In the case of the semi-trailer, such uses could be delivering goods to customers or transporting goods between warehouses and the manufacturing facility or retail outlets.
2. This will be done over the next 12 years (15-year lifetime minus three years already).
3. Depreciation is a term used to describe the reduction in the value of as asset over a number of years.
4. Conceptually, the depreciation expense in accounting refers to the gradual reduction in the recorded value of a fixed asset on the balance sheet from “wear and tear” with time.
5. The depreciation schedule may also include historic and forecasted capital expenditures (CapEx).

In our hypothetical scenario, the company is projected to have $10mm in revenue in the first year of the forecast, 2021. The revenue growth rate will decrease by 1.0% each year until reaching 3.0% in 2025. We’ll now move on to a modeling exercise, which you can access by filling out the form below. Capital expenditures are directly tied to “top line” revenue growth – and depreciation is the reduction of the PP&E purchase value (i.e., expensing of Capex). The average remaining useful life for existing PP&E and useful life assumptions by management (or a rough approximation) are necessary variables for projecting new Capex.

If it seems that the trend in the future is lumpy, or the relationship between future CapEx and depreciation expense becomes dissimilar, consider revisiting the forecasting assumptions for each item. Real estate is a specific industry that requires heavy use of the depreciation schedule. The double declining method (DDB) is a form of accelerated depreciation, where a greater proportion of the total depreciation expense is recognized in the initial stages. So we know these notes will be coming due – after all, Apple is contractually required to pay them down. This might lead you to believe that forecasting debt is just a matter of reducing the current debt balances by these scheduled maturities.

How to Build a Depreciation Schedule

While companies do not break down the book values or depreciation for investors to the level discussed here, the assumptions they use are often discussed in the footnotes to the financial statements. The VDB (variable declining balance) function is a more general depreciation formula that can be used for switching to straight-line (see below). The boolean value TRUE as the last argument tells the function NOT to switch to straight-line.

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). There are always assumptions built into many of the items on these statements that, if changed, can have greater or lesser effects on the company’s bottom line and/or apparent health. Assumptions in depreciation can impact the value of long-term assets and this can affect short-term earnings results.

For accounting and tax purposes, the depreciation expense is calculated and used to “write-off” the cost of purchasing high-value assets over time. Usually a company will want to write-off the asset (meaning turn the cost into an expense) as soon as possible in order to increase the after-tax present worth, or profitability, of an asset. For this and other reasons, governments often regulate the different depreciation methods that eligible companies use. At the bottom of the depreciation schedule, prepare a breakdown of the net change in PP&E. This begins with the beginning balance of PP&E, net of accumulated depreciation. From this beginning balance, add capital expenditures, subtract depreciation expense, and also subtract any sales or write-offs.

The final total should be the ending balance of PP&E, already net of accumulated depreciation. There are a number of built-in functions for depreciation calculation in Excel. These include depreciation waterfall SLN (straight-line), SYD (sum-of-year’s digits), DDB (declining balance with the default being double-declining), VDB (declining balance with switch to straight-line), DB (fixed-declining balance), AMORDEGRC, and AMORLINC. See the description of the various depreciation methods below for how to use the depreciation formulas in Excel. The depreciation expense reduces the carrying value of a fixed asset (PP&E) recorded on a company’s balance sheet based on its useful life and salvage value assumption.

Depreciation is how an asset’s book value is “used up” as it helps to generate revenue. In the case of the semi-trailer, such uses could be delivering goods to customers or transporting goods between warehouses and the manufacturing facility or retail outlets. All of these uses contribute to the revenue those goods generate when they are sold, so it makes sense that the trailer’s value is charged a bit at a time against that revenue. The straight-line methods used in the MACRS system are a little different because they take into account the time of year that the asset was placed into service and follow a half-year, mid-quarter, or mid-month convention.

Therefore, companies using straight-line depreciation will show higher net income and EPS in the initial years. Deferred taxes are a complex topic and, as you see below, are either grown with revenue or straight-lined in the absence of a detailed analysis.

Since Capex was input as a negative, the Capex will increase the PP&E amount as intended (otherwise, the formula would have added Capex if the positive sign convention had been used). For example, the total depreciation for 2023 is comprised of $60k of depreciation from Year 1, $61k of depreciation from Year 2, and then $62k of depreciation from Year 3 – which comes out to $184k in total.
