How is Depreciation Calculated? A Guide for Business Owners
Fixed assets—such as vehicles, machinery, and computer equipment—inevitably lose value over time. Understanding how to calculate and record this depreciation is essential for producing accurate financial statements and maximizing your tax deductions.
Properly managing your fixed asset ledger requires more than just recording a purchase. Our professional bookkeeping support team maintains detailed depreciation schedules to ensure your balance sheet reflects the true value of your business property at all times.
What is Depreciation?
In accounting, depreciation is the systematic allocation of a tangible asset’s cost over its useful life. It is recorded as a non-cash expense, meaning it reduces your reported net income without requiring an actual cash payout each month.
To record this, our bookkeepers enter a journal entry that debits the expense and credits a contra-asset account called Accumulated Depreciation. This allows you to see both the original purchase price and the total value lost since the date of acquisition on your financial reports.
Common Methods for Calculating Depreciation
Depending on your business needs and tax strategy, different methods can be used to spread the cost of an asset:
1. Straight-Line Method
This is the most straightforward approach. You take the original cost of the asset, subtract its estimated salvage value (what it’s worth at the end of its life), and divide that total by the number of years you expect to use it. This results in the same expense amount being recorded every year.
2. Declining Balance Method
This is an “accelerated” method. It allows for larger depreciation expenses in the early years of an asset’s life and smaller expenses in later years. This is often used for technology or vehicles that lose value rapidly the moment they are put into service.
3. Modified Accelerated Cost Recovery System (MACRS)
For tax purposes in the United States, most businesses must use the MACRS method. This system assigns specific “recovery periods” (lifespans) to different classes of assets—for example, 5 years for computers and 7 years for office furniture. Because MACRS is complex, we coordinate directly with your CPA to ensure your internal books align with your tax filings.
IRS Asset Lifespan Classifications
| Asset Category | Standard MACRS Lifespan |
|---|---|
| Computers, Copiers, & Vehicles | 5 Years |
| Office Furniture & Equipment | 7 Years |
| Land Improvements | 15 Years |
| Residential Rental Property | 27.5 Years |

Frequently Asked Questions
What is Section 179 depreciation?
Section 179 allows businesses to deduct the full purchase price of qualifying equipment in the year it is purchased, rather than spreading it out over several years. This is a powerful tool for reducing current year tax liability.
How does depreciation affect my taxes?
Because depreciation is a deductible expense, it reduces your taxable income. By using accelerated methods, you can potentially lower your tax bill significantly in the years you make major capital investments.
