Enter the initial cost ($) and the percent decrease in cost (%) into the Calculator. The calculator will evaluate the Cost Decrease. 

Cost Decrease Formula

CD = IC - IC * C/100

Variables:

  • CD is the Cost Decrease ($)
  • IC is the initial cost ($)
  • C is the percent decrease in cost (%)

To calculate the Cost Decrease, multiply the percent decrease by the initial cost, then subtract the result from the initial cost.

How to Calculate Cost Decrease?

The following steps outline how to calculate the Cost Decrease.


  1. First, determine the initial cost ($). 
  2. Next, determine the percent decrease in cost (%). 
  3. Next, gather the formula from above = CD = IC – IC * C/100.
  4. Finally, calculate the Cost Decrease.
  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.

initial cost ($) = 1000

percent decrease in cost (%) = 25
