The Double Declining Balance method is the most widely used accelerated technique: it doubles the straight-line rate (for a 5-year asset, 40% instead of 20%) and applies that rate to the declining book value each year rather than to the original cost.<\/p>\n<p>The result is a front-loaded expense pattern that often matches economic reality better than straight-line depreciation. Vehicles, computers, and machinery typically lose most of their value in the first few years of use, so recording more expense early reflects how the asset's usefulness is consumed.<\/p>\n<p>There is also a cash-flow incentive: higher depreciation expense reduces taxable income in the early years, deferring tax payments and freeing up cash while the asset is still generating strong returns. Over the full life of the asset, total depreciation is the same as with straight-line \u2014 only the timing differs.<\/p>\n<p>To see the full schedule for the default example (cost $10,000, salvage $1,000, life 5 years), change only the Year field and recalculate:<\/p>\n<table>\n<thead>\n<tr>\n<th>Year<\/th>\n<th>Book Value (Start)<\/th>\n<th>Depreciation<\/th>\n<th>Book Value (End)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1<\/td>\n<td>$10,000.00<\/td>\n<td>$4,000.00<\/td>\n<td>$6,000.00<\/td>\n<\/tr>\n<tr>\n<td>2<\/td>\n<td>$6,000.00<\/td>\n<td>$2,400.00<\/td>\n<td>$3,600.00<\/td>\n<\/tr>\n<tr>\n<td>3<\/td>\n<td>$3,600.00<\/td>\n<td>$1,440.00<\/td>\n<td>$2,160.00<\/td>\n<\/tr>\n<tr>\n<td>4<\/td>\n<td>$2,160.00<\/td>\n<td>$864.00<\/td>\n<td>$1,296.00<\/td>\n<\/tr>\n<tr>\n<td>5<\/td>\n<td>$1,296.00<\/td>\n<td>$296.00<\/td>\n<td>$1,000.00<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Note that in Year 5 the pure formula would give \\(1{,}296 \\times 0.40 = 518.40\\), which would push the book value below the salvage value. The calculator therefore caps the final depreciation at \\(1{,}296 - 1{,}000 = 296\\), so the asset ends its life exactly at salvage value.<\/p>\n<h2>Assumptions, Limitations and Practical Tips<\/h2>\n<ul>\n<li><strong>Salvage value floor:<\/strong> the DDB method ignores salvage value when computing the rate, but depreciation is always limited so the book value never falls below salvage. The last year's expense is automatically adjusted.<\/li>\n<li><strong>Possible switch to straight-line:<\/strong> many tax systems (including US MACRS rules) allow or require switching to straight-line depreciation partway through the asset's life once that produces a larger deduction. This calculator applies pure DDB throughout.<\/li>\n<li><strong>Tax rules vary:<\/strong> which assets qualify for accelerated depreciation, the allowed rates, and the conventions (half-year, mid-quarter) depend on the jurisdiction and current tax law. Check the rules that apply to your business before filing.<\/li>\n<li><strong>Book vs. tax depreciation:<\/strong> companies often use straight-line depreciation in financial statements and accelerated methods only for tax purposes, which creates a temporary difference in reported income.<\/li>\n<li><strong>Choose the useful life carefully:<\/strong> the depreciation rate \\(2\/L\\) is very sensitive to the life estimate. A 3-year asset depreciates at 66.7% per year, while a 10-year asset depreciates at 20%.<\/li>\n<\/ul>\n<p>If you need a depreciation figure that spreads the cost evenly instead, use the <a href=\"https:\/\/wpcalc.com\/en\/finance\/asset-depreciation\/\">Asset Depreciation calculator<\/a> for the straight-line method.
