Calculating fields can be added to every order row, or for every order and opportunity.

When adding a calculating field to an order row, this makes a calculation for every row. 

When creating a calculating field on an order & opportunity this shows in the bottom of every order & opportunity.

A Calculating Field can calculate variables from other custom fields such as Integer, Select, Currency, and Percent.

To make use of Calculating Fields, you need to set up custom fields.

 This article covers:

• Opening Order Row Fields / Order & Opportunities field

   Price - Probability % that the opportunity will be closed, based on position in the sales board. 
   Discount - Discount percentage
   Order value - The total value of the order
   Total gross value - Total price before discount

5. Add a new field for each variable in your formula.
   
   For example, here we've added the integer field Developers and standard field Order value. By dividing total order value with the number of developers we will find out how much on average each developer will charge. How many developers there are in total is decided on how many developers is added on each order row.
   
   
   
   Add operators like +,-,* and / for each field. Just like you would on any calculator. Be sure to add ( ) if needed.
