Businesses use depreciation as a standard accounting practice to spread the cost of assets over their useful lives. To manage finances effectively and make informed decisions, many companies rely on depreciation schedules. This guide explains what depreciation schedules are, why they matter, and how to create and use them.
What is Depreciation?
Depreciation is an accounting technique that reflects the gradual decline in value of a tangible or intangible asset over its useful life. Buildings, machinery, vehicles, and even software or patents all lose value over time. Businesses record this decline on financial statements to present a more accurate picture of asset values. The IRS uses recovery periods and methods such as MACRS (Modified Accelerated Cost Recovery System) to define how quickly different types of assets can be depreciated for tax purposes.
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. Whether you maintain it in a spreadsheet, accounting software, or with the help of a tax professional, a well-organized schedule makes it easier to prepare financial statements, support tax filings, and plan for future capital needs. It typically includes:
- Asset description
- Cost (basis)
- Purchase or placed-in-service date
- Estimated useful life
- Salvage value
- Depreciation method (e.g., straight-line, double declining balance)
- Annual depreciation expense
- Accumulated depreciation
The main purposes of a depreciation schedule include:
- Track the declining value of assets due to wear, tear, or obsolescence
- Document depreciation for financial statements
- Substantiate tax deductions
- 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 guide.
Basis
The basis is the original cost of an asset plus any additional expenses needed to prepare it for use. 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 is the value of an asset on your financial records after subtracting accumulated depreciation from the original cost. 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. Often only the portion of cost above salvage value is depreciated.
Accumulated Depreciation
This is the total depreciation 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
A consulting firm purchases office furniture for $18,000, plus $1,500 for delivery and setup in August. The total basis is $19,500. The furniture is ready for use on September 1, which becomes its placed-in-service date—when depreciation begins.
For tax purposes, office furniture typically falls under 7-year MACRS property. The firm estimates the furniture will be worth $1,500 at the end of its useful life (its salvage value). Each year, the company records depreciation expense, and those amounts add up as accumulated depreciation on the balance sheet. As accumulated depreciation grows, the furniture's book value declines.
Why Use Depreciation Schedules?
Depreciation schedules serve several vital purposes for businesses:
Accurate Financial Reporting
By accounting for depreciation, businesses present financial statements more accurately, reflecting the actual decrease in asset values over time.
Tax Benefits
Depreciation can reduce taxable income, resulting in lower tax liabilities and potentially saving the company money.
Budgeting and Forecasting
Depreciation schedules help businesses plan for the future by providing insights into asset replacement and maintenance costs.
Asset Management
Tracking depreciation helps businesses decide when to replace or upgrade equipment, ensuring optimal operational efficiency.
Common Depreciation Categories
Depreciation categories, also known as asset classes or recovery periods, are IRS classifications that determine appropriate depreciation methods and recovery periods. Each category has a designated number of years over which assets can be depreciated. Knowing which category an asset falls into is essential for building an accurate schedule and avoiding errors on your tax return. The most common ones are:
| Property Class | Examples |
|---|---|
| 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 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 track assets internally or work with a tax professional, building a clear schedule helps ensure accurate reporting and planning.
Here's a step-by-step way to structure one.
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, and ending book value.
Record capital expenditures (CapEx)
List all qualifying business assets purchased during the year—equipment, vehicles, furniture, or technology. Each item should appear as its own row so depreciation can be calculated accurately.
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.
Calculate annual depreciation
Using the chosen method and useful life, compute the annual depreciation expense. That figure feeds into both your depreciation schedule and your financial statements.
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, and reduce book value accordingly.
Tie depreciation to financial performance
While depreciation is a non-cash expense, it impacts taxable income. Many businesses keep depreciation schedules alongside revenue and expense data to understand how capital investments affect profitability and taxes.
Simple Example Layout
| Asset | Placed in Service | Cost | Method | Annual Depreciation | Accum. Depreciation | 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 |
A schedule like this provides a clear view of asset value decline over time and keeps accounting records and tax filings aligned.
Tip: Depreciation vs. Section 179
For qualifying equipment, businesses may elect Section 179 to deduct the full cost in the year of purchase instead of depreciating over time. If you use Section 179, the asset may not appear on your depreciation schedule for that year, but you still need to track it for book purposes and for any remaining basis that will be depreciated in future years.
Which Depreciation Method is Best for My Business?
Several depreciation methods exist, but four are more common than others for businesses and individuals accounting for the reduction in asset value as they are used and age. The right method depends on the type of asset, whether you prioritize tax savings early or prefer consistent expense recognition, and what your industry or lender expects for financial reporting.
Straight-Line Depreciation
The straight-line method is the simplest and most widely used. It allocates an equal amount of depreciation expense each year over the asset's useful life. Because the expense is the same every year, it is easy to forecast and often preferred for financial reporting when management wants consistent, predictable results.
Formula: (Cost of Asset – Salvage Value) ÷ Useful Life
Example: If a business purchases equipment for $20,000 with a salvage value of $0 and an 8-year useful life, the depreciation expense would be $2,500 per year: ($20,000 – $0) ÷ 8 years = $2,500. Each year the accumulated depreciation increases by $2,500 and the book value decreases by the same amount until it reaches zero.
Double Declining Balance Depreciation
This method accelerates depreciation, with higher expenses in the early years. It applies a fixed percentage, often double the straight-line rate, to the asset's book value at the beginning of the year. Commonly used for tax purposes.
Formula: (Book Value at Beginning of Year × Depreciation Rate), where Depreciation Rate = (100% ÷ Useful Life) × 2
For the same $20,000 equipment with 8-year life: (100% ÷ 8) × 2 = 25%. With $2,000 salvage value, 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 | 15,000 | 11,250 | 8,438 | 6,329 | 4,747 | 3,560 | 2,670 | 2,003 |
Units of Production (Activity) Depreciation
This method is based on actual usage or production, making it suitable for machinery, vehicles, or equipment. Depreciation expense depends on units produced, hours of use, or another activity measure.
Formula: (Cost – Salvage Value) × (Units Produced ÷ Total Units Expected)
Example: $20,000 equipment with 1 million estimated units and $0 salvage. If 30,000 units are produced in Year 1: ($20,000 – $0) × (30,000 ÷ 1,000,000) = $600 depreciation. In your schedule, repeat this each year using the units produced that year. A sample schedule with varying production (30k, 70k, 40k, 150k, 240k, 260k, 150k, 60k units) would show depreciation of $600, $1,400, $800, $3,000, $4,800, $5,200, $3,000, and $1,200 across the eight years.
Sum-of-the-Years-Digits (SYD) Depreciation
The SYD method allows accelerated depreciation, with higher expenses in early years and decreasing amounts later. It uses a fraction for each year based on the sum of the years of useful life.
Formula: (Cost – Salvage Value) × (Remaining Useful Life ÷ Sum of Years' Digits)
Example: $20,000 equipment, $0 salvage, 8-year life. Sum of digits = 1+2+3+4+5+6+7+8 = 36. Year 1: ($20,000 – $0) × (8 ÷ 36) = $4,444. In your schedule, repeat each year using the remaining useful life. Year 2 uses 7/36, Year 3 uses 6/36, and so on. The annual depreciation amounts would be $4,444, $3,889, $3,333, $2,778, $2,222, $1,667, $1,111, and $556, with book value declining to zero by the end of Year 8.
