Frequently Asked Questions
What is straight line depreciation?
Straight line depreciation is an accounting method that spreads the cost of an asset evenly over its useful life. It calculates the same depreciation expense each year by dividing the depreciable amount (cost minus salvage value) by the number of years of useful life. This method assumes the asset loses value at a constant rate.
How do you calculate straight line depreciation?
The formula is: Annual Depreciation = (Asset Cost - Salvage Value) / Useful Life in Years. For example, if you buy equipment for $50,000, expect it to be worth $5,000 after 10 years, the annual depreciation would be ($50,000 - $5,000) / 10 = $4,500 per year.
What is salvage value in depreciation?
Salvage value (also called residual value or scrap value) is the estimated value of an asset at the end of its useful life. It represents what you expect to recover when disposing of the asset after fully depreciating it. This could be from selling, trading in, or scrapping the asset.
