Depreciation Schedules for Business Assets

Key Takeaways:

• Depreciation schedules spread asset costs over time for accurate financial reporting and tax deductions.
• Basis and placed-in-service date control when depreciation starts and how much can be depreciated.
• Depreciation lowers taxable income while reducing an asset’s book value on financial statements.
• IRS recovery periods determine depreciation timelines for equipment, vehicles, and real estate.
• Depreciation method choice affects cash flow, with accelerated methods increasing early tax savings.
• Accurate schedules improve forecasting and compliance by supporting budgeting, tax planning, and asset management.

Depreciation is a common accounting method used by businesses to allocate the cost of their assets over time. To effectively manage their finances and make informed decisions, businesses employ depreciation schedules. In this article, we will explore what depreciation schedules are, why they are essential for businesses, and how to create and utilize them effectively. 

What is Depreciation? 

Depreciation is an accounting method that reflects the gradual decrease in the value of a tangible or intangible asset over its useful life. Assets like buildings, machinery, vehicles, and even software or patents all depreciate over time. Businesses recognize this decrease in value on their financial statements to ensure a more accurate representation of their asset values. 

What is a Depreciation Schedule?

A depreciation schedule is a detailed table that lists each depreciable asset and shows how its cost is allocated as depreciation expense over its useful life for accounting and tax purposes. It typically includes:

• Asset description
• Cost (basis)
• Purchase/placed-in-service date
• Estimated useful life
• Salvage value
• Chosen depreciation method (e.g., straight-line, double declining balance)
• Annual depreciation expense
• Accumulated depreciation

In short the main purposes of a depreciation schedule include:

1. Track the declining value of assets due to wear, tear, or obsolescence
2. Document depreciation for financial statements
3. Substantiate tax deductions
4. Plan replacements and capital expenditures

Key Terms

Before diving into depreciation schedules, it helps to understand a few core terms you’ll see throughout this article.

• Basis: The basis is the original cost of an asset plus any additional expenses needed to prepare it for use in your business. For example, the purchase price of a machine plus shipping and installation charges make up its basis.
• Placed-In-Service Date: This is the date when an asset is ready and available for its intended use. Depreciation begins on this date for tax and accounting purposes.
• Book Value: Book value refers to the value of an asset on your financial records after subtracting accumulated depreciation from the original cost. Over time, as you record depreciation, an asset’s book value declines. 
• Salvage Value: Salvage value is an estimate of what an asset will be worth at the end of its useful life. It’s often used to calculate annual depreciation because only the portion of cost above salvage value is depreciated.
• Accumulated Depreciation: This is the total depreciation that has been recorded on an asset since it was placed in service. It increases each year and represents the cumulative expense recognized against the asset’s value.

Example

Imagine a small business purchases a commercial printer for $30,000, plus $2,000 for delivery and installation in June. The total basis of the asset is $32,000. The printer is fully set up and ready to use on July 1, which becomes its placed-in-service date—the point at which depreciation begins.

For tax purposes, most business equipment like commercial printers falls under 5-year MACRS property, meaning the IRS allows depreciation to be spread over five years starting from the placed-in-service date. The business estimates the printer will be worth $2,000 at the end of its useful life, which is its salvage value. Each year, the company records depreciation expense, and those annual amounts add up as accumulated depreciation on the balance sheet. As accumulated depreciation grows, the printer’s book value declines, reflecting its reduced value on the company’s financial records over time.

Why Use Depreciation Schedules? 

Depreciation schedules serve several vital purposes for businesses: 

1. Accurate Financial Reporting: By accounting for depreciation, businesses can present their financial statements more accurately, reflecting the actual decrease in the value of their assets over time. 

2. Tax Benefits: Depreciation can reduce a business’s taxable income, resulting in lower tax liabilities and potentially saving the company money.  

3. Budgeting and Forecasting: Depreciation schedules help businesses plan for the future by providing insights into asset replacement and maintenance costs. 

4. Asset Management: Tracking the depreciation of assets helps businesses make informed decisions about when to replace or upgrade equipment and machinery, ensuring optimal operational efficiency. 

Common Depreciation Categories 

Depreciation categories, also known as asset classes or recovery periods, are classifications used by the IRS to determine the appropriate depreciation methods and recovery periods for various types of assets. Each category has a designated number of years over which assets in that category can be depreciated. The most common ones are: 

• 3-year property: tractors, manufacturing tools, livestock 
• 5-year property: computers, office equipment, cars, light trucks, construction equipment 
• 7-year property: office furniture, appliances, agricultural equipment, property not placed in another category 
• 27.5-year property: residential rental properties 
• 39-year property: commercial buildings 

How to Build a Depreciation Schedule

A depreciation schedule is a structured table that shows how the cost of a business asset is expensed over time. Whether you’re tracking assets internally or working with a tax professional, building a clear schedule helps ensure accurate reporting and planning.

Here’s a step-by-step way to structure one.

1. Set up the basic rows and columns.

Start with a table that tracks each asset separately. Common columns include:

• Asset description
• Purchase date
• Placed-in-service date
• Original cost (basis)
• Depreciation method
• Useful life
• Annual depreciation expense
• Accumulated depreciation
• Ending book value

2. Record capital expenditures (CapEx).

List all qualifying business assets purchased during the year, such as equipment, vehicles, furniture, or technology. Each item should appear as its own row so depreciation can be calculated accurately.

3. Choose and note the depreciation method.

For each asset, identify the method being used, such as straight-line or an accelerated method. This determines how quickly the asset’s cost is written off.

4. Calculate annual depreciation.

Based on the method and useful life, calculate how much depreciation expense applies each year. This amount flows into both your depreciation schedule and your financial statements.

5. Track the roll-forward each year.

A depreciation schedule is not static. Each year, you:

• Add new assets placed in service
• Continue depreciating existing assets
• Update accumulated depreciation
• Reduce the book value accordingly

6. Tie depreciation to financial performance.

While depreciation itself is a non-cash expense, it impacts taxable income. Many businesses keep depreciation schedules alongside revenue and expense data to better understand how capital investments affect profitability and taxes.

Simple Example Layout

Asset Name	In-Service Date	Cost	Method	Annual Dep.	Accumulated Dep.	Book Value
Office Computer	03/01/2024	$3,000	Straight-Line	$600	$600	$2,400
Delivery Van	06/15/2024	$25,000	Accelerated	$5,000	$5,000	$20,000

This type of schedule gives you a clear snapshot of how your assets lose value over time and helps ensure consistency across accounting records and tax filings.

Which Depreciation Method is Best for My Business? 

While there are several methods of depreciation, we do often see four that are more common than others that help businesses and individuals account for the reduction in the value of assets as they are used and age. They are: 

Straight-Line Depreciation 

The straight-line method is the simplest and most widely used depreciation method. It allocates an equal amount of depreciation expense each year over the asset’s useful life. 

The formula for straight-line depreciation is: (Cost of Asset – Salvage Value) / Useful Life 

For example, if a business purchases a piece of equipment for $20,000 and determines that it will have a salvage value of $0 and last about 8 years, the depreciation expense would be $2,500. 

($20,000 – $0) / 8 years = $2,500 per year 

Double Declining Balance Depreciation 

The double declining balance method accelerates depreciation, with higher expenses in the early years of an asset’s life. It calculates depreciation by applying a fixed percentage, often double the straight-line rate, to the asset’s book value at the beginning of the year. This method is commonly used for tax purposes. 

The formula for double declining balance depreciation is: (Book Value at the Beginning of the Year x Depreciation Rate) 

The formula for the depreciation rate is: (100% / Useful Life of Asset) x 2 

For example, if you depreciated the same piece of equipment as above, the depreciation rate would be: 

(100% / 8years) x 2 = 25% 

Then suppose you determined the equipment had a salvage value of $2,000. You would have the following depreciation schedule: 

		Year 1	Year 2	Year 3	Year 4	Year 5	Year 6	Year 7	Year 8
Open Book Value		20,000	15,000	11,250	8,438	6,329	4,747	3,560	2,670
Depreciation	25%	5,000	3,750	2,813	2,109	1,582	1,187	890	668
End Book Value	20,000	15,000	11,250	8,438	6,329	4,747	3,560	2,670	2,003

Units of Production (or Activity) Depreciation: 

This method is based on the actual usage or production of the asset, making it suitable for assets like machinery, vehicles, or equipment. Depreciation expense is based on the number of units produced, hours of use, or some other measure of activity. 

The formula for units of production depreciation is: (Cost of Asset – Salvage Value) x (Units Produced/Total Units Expected) 

For example, let’s say your business purchased a $20,000 piece of equipment with an estimated unit production of 1 million and a $0 salvage value. During the first year of business, the equipment produced 30,000 units. 

($20,000 – $0) x (30,000 / 1 million) = $600 

In your depreciation schedule, you’d repeat this process every year using the number of units produced. 

		Year 1	Year 2	Year 3	Year 4	Year 5	Year 6	Year 7	Year 8
Production		30k	70k	40k	150k	240k	260k	150k	60k
Open Book Value		20,000	19,400	18,000	17,200	14,200	9,400	4,200	1,200
Depreciation		600	1,400	800	3,000	4,800	5,200	3,000	1,200
End Book Value	20,000	19,400	18,000	17,200	14,200	9,400	4,200	1,200	–

Sum-of-the-Years-Digits (SYD) Depreciation: 

The SYD method allows for accelerated depreciation, with higher expenses in the early years and decreasing amounts in later years. It involves calculating a fraction for each year based on the sum of the years of an asset’s useful life. 

The formula for SYD depreciation is: (Cost of Asset – Salvage Value) x (Remaining Useful Life / Sum of the Years’ Digits) 

For example, let’s say your business purchased a $20,000 piece of equipment with a $0 salvage value and a lifespan of 8 years. The sum of the years’ digits is 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36 years. The remaining life in the beginning of the first year is 8.  

Year 1: ($20,000 – $0) x (8 years/ 36) = $4,444 

In your depreciation schedule, you’d repeat this process every year using the remaining useful life. 

		Year 1	Year 2	Year 3	Year 4	Year 5	Year 6	Year 7	Year 8
Remaining Life		8	7	6	5	4	3	2	1
Open Book Value		20,000	15,556	11,667	8,334	5,556	3,334	1,667	556
Depreciation		4,444	3,889	3,333	2,778	2,222	1,667	1,111	556
End Book Value	20,000	15,556	11,667	8,334	5,556	3,334	1,667	556	0

Frequently Asked Questions

What is the depreciation basis and how is it calculated?

The depreciation basis is the total cost of an asset, including the purchase price plus any costs required to prepare it for use, such as shipping, installation, and setup.

What does “date placed in service” mean and why does it matter?

The placed-in-service date is when an asset is ready and available for its intended business use, and it determines when depreciation begins for tax and accounting purposes.

How do you set up a depreciation schedule tied to financial projections?

A depreciation schedule is built by listing each asset’s basis, placed-in-service date, useful life, and depreciation method, then projecting annual depreciation expense over the asset’s life to align with forecasted financial statements.

How can you infer the depreciation method from historical financials?

You can often infer the depreciation method by comparing annual depreciation expense to asset cost and useful life, as consistent expense amounts typically indicate straight-line depreciation.

What are common options to forecast depreciation in models when details are unknown?

When details are limited, analysts commonly assume straight-line depreciation over standard useful lives or estimate depreciation as a percentage of gross fixed assets based on historical averages.
