Enter the length (in), the width (in), the thickness (in), and cost per cubic in ($/in^3) into the Plate Cost Calculator. The calculator will evaluate and display the Plate Cost. 

Plate Cost Formula

The following formula is used to calculate the Plate Cost. 


  • Where PC is the Plate Cost ($)
  • L is the length (in) 
  • W is the width (in) 
  • T is the thickness (in) 
  • CPSI is the cost per cubic inch ($/in^3)

How to Calculate Plate Cost?

The following example problems outline how to calculate Plate Cost.

Example Problem #1

  1. First, determine the length (in). The length (in) is given as 20 .
  2. Next, determine the width (in). The width (in) is calculated as  10 .
  3. Next, determine the thickness (in). The thickness (in) is found to be .5.
  4. Next, determine the cost per cubic in ($/in^3). This is example, the is given is $5.00.
  5. Finally, calculate the Plate Cost using the formula above: 


Inserting the values from above yields: 

PC = 20*10*.5*5 = 500.00 ($)

Example Problem #2

The variables needed for this problem are provided below:

length (in) = 30

width (in) = 5

thickness (in) = .25

cost per cubic in ($/in^3) = 3.00

Entering these values and solving gives:

PC = 30*5*.25*3.00= 112.5 ($)
