    Custom Calculation Form: Can we dynamically change a product price based on a quantity?

    Asked by dirtymall on August 28, 2016 at 04:32 AM


    I see many about the calculation questions,never see like me request.here have a similar website:

    https://easyeda.com/order, changed size and quantity can lead to the change of the price.

    Note:assume that calculation way is $250/m²,(LxWxQ) / 10000 x $250=price


    Fox example: (100mmx100mmx10pcs)/1000000x$250=$25

    and there have some costs are fixed , So when you choose them also will changes total price (like my form)

    I just want to kown using the Jotform can get like that ?

    We do not have an option to change the product price dynamically, but since you are using custom calculations it is most likely possible to implement it manually.

    Here is an example of changing the product price based on quantity:

    - Number field is used as Quantity.

    - Form Calculation fields.

    - Product Price is populated based on conditional logic.

    If the quantity is <100 the price is 10, if the quantity is >=100 the price is 8.


    Link to the form:


    You can clone it to check the backend.

    Please also note that calculation values should be without the $ dollar sign.

    If you need any further assistance, please let us know.
