What is depreciation?

Depreciation allocates the cost of a tangible asset over its useful life for accounting and tax purposes. Accountdesq's Depreciation Schedule Generator goes beyond a single year-end number: choose Straight-Line (equal periods) or Reducing Balance (double declining, or a custom annual rate) depreciation, monthly or yearly schedule frequency, and first-period proration for assets purchased mid-period. Once you've generated a schedule, save the asset into a running Fixed Asset Register - add as many assets as you're tracking, each with its own method and useful life, and see combined totals for original cost, accumulated depreciation, and net book value, plus a chart comparing cost to current book value across every asset.

How it works

Enter the asset cost, salvage value, useful life, purchase and depreciation start dates, and choose your method, frequency, and rounding precision. The tool generates the full period-by-period schedule, a book value trend chart, and key insights. Click 'Save to Register' to add the asset to your running Fixed Asset Register, then repeat for every asset you're tracking - the register shows combined totals and a cost-vs-book-value comparison chart across all saved assets, plus its own PDF/Excel export.

Why it matters

Depreciation affects both your P&L (as an expense) and your Balance Sheet (as accumulated depreciation) - getting it right, asset by asset, is essential for accurate financial statements and tax returns. Most free depreciation calculators only handle one asset at a time with no way to see the combined picture; tracking a full asset register here means you always know the total net book value of everything the business owns.

Common mistakes

  • Using the wrong method - check what your tax authority allows for your asset class
  • Forgetting to use salvage value - don't depreciate below residual value
  • Not tracking individual assets in one place - relying on memory or scattered spreadsheets for what should be a single fixed asset register
  • Ignoring first-period proration for assets purchased partway through a month or year, which overstates the first period's depreciation

Best practices

  • Align your accounting depreciation with tax depreciation where possible
  • Review useful life estimates annually - technology assets often become obsolete faster than originally planned
  • Use reducing balance for assets that lose value quickly (vehicles, tech); straight-line for buildings and steady-use equipment
  • Save every asset into the register as you set it up, so the combined net book value is always current
