Depreciation Methods

Depreciation in ERP Enigma is the systematic allocation of an asset’s cost over its useful life.

The system automatically generates a depreciation schedule based on the Depreciation Method, Total Number of Depreciations, and other inputs such as the Available-for-Use Date in the Asset record. Multiple schedules can also be created for different Finance Books.

Note: > To generate a depreciation schedule automatically, ensure that > ‘Calculate Depreciation’ > is enabled while creating the asset. >

1. Depreciation Methods in ERP Enigma


1.1 Straight Line

  • The asset value is reduced uniformly over its useful life until it reaches its salvage value.
  • Useful when depreciation occurs evenly over time.

Example: If an asset costs 1,000 and its salvage value is 500 after 5 years, depreciation would be 100 per year.

Additional Options:

  • Depreciate based on daily pro-rata: Adjust depreciation based on the number of days in a month.
  • Depreciate based on shifts: Adjust depreciation based on asset usage per shift. Define shift factors in Asset Shift Factor and allocate them using Asset Shift Allocation.

1.2 Double Declining Balance

  • Also called 200% declining balance .
  • Depreciates faster in the initial years and slows down later.

Example: If an asset costs 100,000 and its salvage value is 11,000 after 8 years, depreciation in early years will be higher than in later years.

1.3 Written Down Value (WDV)

  • Depreciation is applied to the current written down value of the asset each period.
  • Useful for assets that lose more value in the initial years.

Example: If an asset costs 1,000 with a depreciation rate of 40% over 5 years, each year the depreciation is 40% of the remaining value .

1.4 Manual

  • The system generates a default schedule based on asset details.
  • You can edit dates and depreciation amounts manually for any period as needed.

2. Automatic Depreciation Entries


  • Enable automatic depreciation in Accounts Settings to post entries automatically on scheduled dates.
  • Otherwise, create entries manually using the Make Depreciation Entry button in the Depreciation Schedule row.

The related accounts can be set in the Asset Category or Company .

3. Accounting Entries on Depreciation


When depreciation is posted:

  • Accumulated Depreciation Account is credited
  • Depreciation Expense Account is debited

The related accounts are defined in the > Asset Category > or > Company > master. >

4. Asset Value Chart


  • ERP Enigma displays the net value of the asset over different depreciation dates in a line chart for better visualization.
  • Asset Shift Allocation
  • Asset Maintenance
