1. What is Straight-line Depreciation?

Straight-line depreciation is the simplest method for calculating depreciation expense. It allocates an equal amount of depreciation each year over the asset's useful life, without considering any salvage value.

2. How Does the Calculator Work?

The calculator uses the straight-line depreciation formula:

Where:

• \( Dep \) — Annual depreciation expense (USD)
• \( Cost \) — Original cost of the asset (USD)
• \( Life \) — Useful life of the asset (years)

Explanation: The total cost of the asset is divided equally over its useful life to determine the annual depreciation expense.

3. Importance of Depreciation Calculation

Details: Accurate depreciation calculation is essential for financial reporting, tax purposes, and understanding the true cost of asset ownership over time.

4. Using the Calculator

Tips: Enter the original cost of the asset in USD and its expected useful life in years. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: When is straight-line depreciation most appropriate?
A: Straight-line is best for assets that provide consistent benefits over their useful lives and don't have significant salvage value.

Q2: How does this differ from depreciation with salvage value?
A: With salvage value, you subtract the salvage amount from cost before dividing by life. This version assumes zero salvage value.

Q3: What types of assets typically use this method?
A: Office furniture, buildings, and other assets that lose value evenly over time are good candidates.

Q4: Can I use this for tax purposes?
A: Tax regulations may require different methods (like MACRS), so consult a tax professional for tax-related depreciation.

Q5: What if my asset's useful life changes?
A: You would need to recalculate depreciation based on the remaining book value and new estimated life.
