Introduction

Asset Depreciation

Depreciation allocates the cost of tangible assets over useful life for accounting and tax. Enter cost, salvage value, life, and method to generate schedules.

Methods

  • Straight line: equal expense each year.
  • Declining balance (200%): more expense early.
  • Sum-of-years-digits: accelerated but smoother than DDB.

Partial First Year

Enable placed-in-service month to prorate year-one depreciation when assets start mid-year - required for many tax returns.

Tax vs Books

MACRS tax depreciation differs from book methods. Consult a CPA for filing; this tool teaches mechanics.

Book Value

Ending book value equals cost minus accumulated depreciation. Salvage value sets the floor below which the asset is not depreciated further under straight line.
