Hey there. so firstly, I apologize, i have no idea how to write the manual formulas.

I’m working to build an instant quote for a print shop and need to encorporate quantity discounts. To give an example:

a Catalog –
number of black ink only pages (one price per impression)
cost per black and white impression (hidden field)
number of full color pages (one price per impression)
cost per color impression (hidden field)
page size
quantity

using the built in calculation formula thing I can get a correct price, but I want the cost per impression to go down based on quantity. with the built in formula, i currently have set the following:

Quantity
*
Number of black and white pages * black ink cost + number of color pages * color ink cost
*
size

how would i write this as a manual formula to go down a set number per impression based on the quantity? Can this be done?

Hi there,

Thanks for using Caldera Forms, it means a lot to us.

Caldera Forms is not a good fit for this. It is stated in our documentation for calculation fields that other types of functions outside of the math function cannot be called (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math). See: https://calderaforms.com/doc/calculation-fields/. What you’re describing would take an if statement, you would have to create a custom snippet for this.

Alternatively, you could separate your desired outcome into two fields, including a hidden one that then toggles the change in price range shift.
