What is Variable Declining Balance Depreciation (VDB)?

VDB is the most versatile and advanced depreciation method. It combines declining balance with automatic switching to straight-line when beneficial, ensuring you always reach exactly zero or salvage value!

Why Variable Declining Balance Depreciation is Superior:

  • Always accurate: Depreciates exactly to zero or salvage value
  • Intelligent switching: Automatically switches to straight-line when optimal
  • Flexible periods: Calculate depreciation for any time period
  • Custom factors: Use any factor (default is 2 for double-declining)
  • Full control: Option to disable automatic switching

Excel Variable Declining Balance Depreciation Function Arguments

ArgumentDescription
costOriginal cost of the asset
salvageValue at end of useful life
lifeUseful life in periods (years, months, etc.)
start_periodBeginning of period to calculate (must match life units)
end_periodEnd of period to calculate (must match life units)
[factor]Optional: Depreciation rate (default: 2 for DDB)
[no_switch]Optional: TRUE = stay declining, FALSE = switch to straight-line (default: FALSE)
Period Examples for 5-Year Asset:
=VDB(80000,4000,5,0,1) – Year 1 (period 0 to 1)
=VDB(80000,4000,5,1,2) – Year 2 (period 1 to 2)
=VDB(80000,4000,5,2,3) – Year 3 (period 2 to 3)

Note: Start_period begins at 0, not 1!

Flexible Time Periods

VDB works with ANY time unit – just keep it consistent!

Monthly Example: =VDB(100000,5000,60,0,3)

Calculates first 3 months for asset with 60-month life

📝 Step-by-Step Excel Practice Tutorial

This practice demonstrates the difference between setting no_switch to TRUE versus FALSE. You’ll create two columns to compare both methods side-by-side.

  1. Create a new Excel worksheet named VDB.
  2. Enter the data:
    • Cell B1: 80000 (Cost)
    • Cell B2: 4000 (Salvage)
    • Cell B3: 5 (Life)
    • Cells A6-A10: 1, 2, 3, 4, 5
    • Cell B5: “No Switch = TRUE”
    • Cell C5: “No Switch = FALSE”
  3. In cell B6:
    Type =VDB($B$1,$B$2,$B$3,A6-1,A6,2,TRUE)
    Press Ctrl + Enter
  4. Drag B6 down through B10
  5. In cell C6:
    Type =VDB($B$1,$B$2,$B$3,A6-1,A6)
    Press Ctrl + Enter
  6. Drag C6 down through C10
  7. Sum cells B11 and C11
  8. Compare: FALSE reaches $76,000 exactly!
