Enter the scrap value ($), the written down value ($), and the useful life of asset (periods) into the WDV Rate Calculator. The calculator will evaluate the WDV Rate. 

WDV Rate Formula

The following formula is used to calculate the WDV Rate. 

WDV = [1 – (SV/WV)^(1/n)] *100

  • Where WDV is the WDV Rate (%)
  • SV is the scrap value ($) 
  • WV is the written down value ($) 
  • n is the useful life of asset (periods) 

How to Calculate WDV Rate?

The following two example problems outline the steps and information needed to calculate the WDV Rate.

Example Problem #1

  1. First, determine the scrap value ($).
    • The scrap value ($) is calculated to be : 3.
  2. Next, determine the written down value ($). 
    • The written down value ($) is measured to be: 10.
  3. Next, determine the useful life of asset (periods). 
    • The useful life of asset (periods) is found to be: 5.
  4. Finally, calculate the WDV Rate using the formula above: 

WDV = [1 – (SV/WV)^(1/n)] *100

The values provided above are inserted into the equation below and computed.

WDV = [1 – (3/10)^(1/5) ]*100 = 21.399 (%)


Example Problem #2

The variables required for this problem are provided below:

scrap value ($) = 6

written down value ($) = 15

useful life of asset (periods) = 4

Test your knowledge using the equation and check your answer with the calculator.

WDV = [1 – (SV/WV)^(1/n)] *100 = (%)
