Enter the amount of degradation (%) and the time (years) into the Calculator. The calculator will evaluate the Degradation Rate. 

Degradation Rate Formula



  • DEGR is the Degradation Rate ($/year)
  • DEG is the amount of degradation (%)
  • T is the time (years)

To calculate the Degradation Rate, divide the amount of degradation by the total time.

How to Calculate Degradation Rate?

The following steps outline how to calculate the Degradation Rate.

  1. First, determine the amount of degradation (%). 
  2. Next, determine the time (years). 
  3. Next, gather the formula from above = DEGR = DEG / T.
  4. Finally, calculate the Degradation Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

amount of degradation (%) = 25

time (years) = 5
