Depreciation Definition

Depreciation is the accounting process of spreading the cost of a tangible asset over its useful life. Instead of recording the entire cost of equipment, vehicles, or buildings as an expense in the year you buy them, depreciation allocates that cost gradually — matching the expense to the revenue the asset helps generate. It's a non-cash expense that reduces taxable income.

Depreciation in Practice — Example

A plumbing company buys a work van for $45,000 with an expected useful life of 5 years and no salvage value. Using straight-line depreciation, they record $9,000/year as a depreciation expense. Each year, the van's book value decreases by $9,000 on the balance sheet. After 5 years, it's fully depreciated (book value = $0), even though the van might still be in use. The company deducted $9,000/year against taxable income — a significant tax benefit — without spending any additional cash after the initial purchase.

Why Depreciation Matters for Your Business

Depreciation is one of the most valuable tax benefits available to businesses. It lets you deduct the cost of expensive assets over time, reducing your taxable income each year. For businesses that invest in equipment, vehicles, or property, depreciation can save thousands in taxes annually.

Beyond taxes, depreciation gives you a more accurate picture of profitability. If you bought $100,000 in equipment this year, expensing it all at once would make this year look terrible and next year look artificially great. Depreciation smooths the expense to reflect reality — the equipment serves you for years, so the cost should be spread across those years.

Depreciation also affects asset valuation. When you sell equipment or property, the difference between the sale price and the depreciated book value determines your taxable gain or loss. Understanding depreciation helps you make better decisions about when to sell, trade in, or replace assets.

How Depreciation Works

Common Methods:

MethodHow It WorksBest For
Straight-LineEqual amount each yearSimple, predictable
Double Declining BalanceLarger deductions early, smaller laterAssets that lose value quickly
MACRSIRS-specified schedulesTax reporting (required in US)
Section 179Full deduction in year of purchaseSmall businesses, assets under $1.16M

Straight-Line Formula:

``

Annual Depreciation = (Cost − Salvage Value) ÷ Useful Life

``

MACRS Recovery Periods (common):

  • Computers & office equipment: 5 years
  • Vehicles: 5 years
  • Office furniture: 7 years
  • Commercial buildings: 39 years
  • Residential rental: 27.5 years
  • Depreciation vs Amortization

    Depreciation applies to tangible assets (equipment, buildings, vehicles). Amortization applies to intangible assets (patents, trademarks, goodwill, software licenses). Both spread costs over time, but they cover different types of assets. If you can touch it, it's depreciation. If you can't, it's amortization.

    FAQ

    Q: Should I use Section 179 or regular depreciation?

    A: Section 179 lets you deduct the full cost of qualifying assets in the year of purchase — great for cash flow and tax savings now. Regular depreciation spreads it out. If you need the tax deduction this year, Section 179 is usually better. Consult your accountant for your specific situation.

    Q: Does depreciation affect my cash flow?

    A: Not directly — depreciation is a non-cash expense. But it reduces your taxable income, which means you pay less in taxes, which does improve cash flow. It's one of the few ways to reduce taxes without spending more money.
