Depreciation Methods: Straight Line, Double Declining & Units of Production

Depreciation Calculation Methods
📏 The three most common depreciation methods are straight-line, double declining balance, and units of production.
📐 The straight-line method expenses an equal amount of depreciation every year over the asset's useful life.
📉 The formula for straight-line depreciation is: $\text{Cost} - \text{Salvage Value} / \text{Useful Life (in years)}$.

Accelerated Depreciation (Double Declining Balance)
⚡ The double declining balance method is an accelerated depreciation approach, resulting in greater depreciation expense in the early years.
📊 This method requires building a detailed depreciation schedule and can be beneficial for companies looking to lower their tax bill early on by increasing depreciation expense, thereby reducing taxable income.
✖️ The calculation involves taking $(2 / \text{Useful Life})$ multiplied by the beginning period book value of the asset.

Units of Production Method
🏭 The depreciation expense under the units of production method varies each year and is directly tied to the actual output the asset produces.
🎯 This method is ideal for companies that wish to match actual business output to the depreciation expense incurred.
➗ To calculate, take the $\text{Units Produced in Period} / \text{Lifetime Units Remaining}$, and multiply this percentage by $(\text{Cost} - \text{Salvage Value})$.

Key Points & Insights
➡️ Companies can choose different methods based on their financial goals, such as maximizing early tax deductions using double declining balance.
➡️ The straight-line method provides predictable, equal annual expense calculations.
➡️ The units of production method aligns expense recognition directly with asset utilization and output volume.
