ZIMSEC O Level Principles of Accounts Notes: Calculating/Estimating depreciation: The Revaluation Method

  • When there are a few big fixed assets it is easy to:
    1. Ascertain the cost
    2. Estimate its useful life
    3. Calculate/estimate its depreciation
    4. Account for its disposal
    5. Calculate/estimate profit or loss on disposal
  • For each asset because it is worth the effort
  • There are times when this cannot be done mainly because
  • It would be too expensive to track and account for the depreciation of each asset
  • It might even be impossible to do this in some instances for some fixed assets
  • A typical example is that of low cost fixed assets which are often bought in large numbers
  • For example screw drivers and spanners in a garage or guns in an army
  • It would be possible to calculate the depreciation of each screw driver, gun or spanner
  • But it would not be worth it, in fact it is quite possible the cost of doing so would exceed the cost of each asset
  • In such cases depreciation is calculated using the revaluation method
  • The value of all the individual assets is added up
  • The cost of additional fixed assets is added to this amount
  • Then the value of the assets at the end of the period is subtracted
  • The resulting figure would yield the depreciation for the year

  • The depreciation figure is then charged into the books
  • Double entry for the revaluation method would be as follows:

  • Examples of the method will be encountered during the discussion of manufacturing businesses where they will be dealt with
