The Straight Line Accounting Method, commonly referred to as SLAM, is an accounting method used in the calculation of depreciation. This method calculates the annual depreciation expense by taking the cost of the asset minus its estimated salvage value, dividing it by the total useful life of the asset then allocating that amount evenly over its lifetime.

SLAM offers a straightforward approach for calculating depreciation expenses. It’s attractive for businesses that want to predictably and accurately plan for their long term expenses. Businesses can make use of this method to ensure accurate tracking of assets for tax and accounting purposes.
