Depreciation: Why We Don't Expense Big Purchases All at Once

Why doesn't a business just expense a $4,000 espresso machine the day it buys it? The answer to that question is the foundation of depreciation — and of accrual accounting more broadly. In this first episode of Depreciation Methods: From Concepts to Calculation, we introduce the concept of depreciation, explain the accounting principle behind it, and lay the groundwork for the methods we'll cover across the rest of the series. We cover: ● Why immediately expensing a long-lived asset produces misleading financial statements ● The matching principle — how accrual accounting ties costs to the periods that benefit from them ● What it means to capitalize an asset vs. expense it — and how that decision triggers depreciation ● The three inputs every depreciation calculation requires: cost, useful life, and salvage value ● The depreciable base — the amount we'll actually spread across the asset's life ● A preview of the depreciation methods we'll cover: straight-line, declining balance, units of production, and tax depreciation By the end of this video, you'll understand: ● Why depreciation exists and what problem it solves ● The difference between capitalizing and expensing a purchase — and when each applies ● What information you need before you can calculate depreciation under any method In the next episode, we'll start with the most common method: straight-line depreciation. 👉 Visit us at intellicasts.com to explore more resources and courses.
