Aside from Conditional Logic, you can also use the Form Calculation widget to perform calculations in Jotform.
Here’s how to set up a Form Calculation widget:
- In Form Builder, click on Add Form Element in the upper-left corner.

- In the left pane, choose Widgets at the top.
- Search and select Form Calculation.

- Click on the widget’s wand icon to open Widget Settings.
- In the right pane, use the Add Field button and virtual numeric keypad to build your formula.
- Once you’re done, click on Save in the lower-right corner.

Did you know?
You can use radio buttons, dropdowns, and checkboxes in calculations. To learn more, see Assigning Calculation Values.

Notes:
- You can click on items in the formula to switch their value types to numeric or string — indicated by the trailing [0-9] and [A-Z] respectively.
- Click on the ellipsis button in Widget Settings to view available math functions and more options. Here are the available options:
- Add fields to the equation as text or string by default.
- Set the result field to read-only.
- Show empty decimal places.
- Ignore hidden fields.
- Use commas for the decimal point.
- Set the number of decimal places in numerical results.

Is there really no simple sum function? I'm going to be including an input table in my form with the option to fill in up to 60 lines and would like to have the total from one column automatically calculated. Do I really have to insert those 60 fields and then individually add a + between each one?
I found your platform when I was searching for tips on creating a form in Excel because it was being advertised as an alternative. But this is a pretty big limitation. If not for the need to put info in a table and have one of the columns automatically calculated, I would just make my form in Adobe or Google forms...

I am also trying with decimal numbers but it doesn't work, it calculates values at random. Should I use a comma or a period? Using the comma they are forced to use the formula / 100 but in any case the result is often wrong.
I'm calculating two values for example A) Value 9 * B) Value 7 = result 63 . But I want to assign a minimum value to the result, for example, when my min value is 70 and my calculation result is 63, I want it to be displayed as 70 in the form. If the value is above 70, I want to see the actual calculation result.
I am trying to calculate the average of 6 numbers. The youtube videos don't quite give me enough instruction to make the calculations work. So if I add 6 number forms and a total form then I can add them okay but the averaging function or manual syntax for division doesn't work.
