# How to Perform Form Calculation Using a Widget

**Last Update: May 20, 2017**

Wondering how you can calculate a total based on the option selected by the user from your form? Calculation is now possible with Jotform. There are **two ways** on this, you can use Conditional Logic or you can use the Form Calculation widget. In this guide, we will discuss how we can use the widget to perform a calculation.

**Video Tutorial**

Below are the steps to help you better:

1. Click on **Form Elements**.

2. Click on the **Widgets tab**, search for "**Form Calculation**" and add it to your form.

3. Now as an example, we will calculate the price of the product selected on a radio button multiplied to a quantity field. Here's how it looks like:

Note: If you want to assign a calculation value on a radio button, drop down or check box field, then you need to check this guide: How to Assign Calculation Value

4. Click on the wand icon.

5. And then click on the "**Add Field**" button, in order to add fields you want to be part of your formula.

6. Finally, once you are done with the formula, click on the **Save** button.

If you want to perform advance mathematical operations, you can check this as a reference: Form Calculation - Math Function Reference

Here's an example form based on our steps above: https://form.jotform.com/63404144341950

The Form Calculation widget is not limited to the example I presented, it would depend on the requirement you need or how complex your formula is.

Questions? Please let us know below!

orangesHow do i associate a number value with a text option as was done in the example.

It appears that the radio buttons and drop down option have a number associated with them although they are text.

supportadvHi, the "Calculate field" option is not happearing on radio button field in my form.

Is it a premium feature? Or is there some other reason?

from the guide:

"Note that the calculation function would only work with the following fields with Numeric entries/options:

1. Radio Button"

MarkPuttThis doesn't work at all really. It only sees 4 fields that I absolutely don't need to calculate.

afla21How do I get the calculator to ignore unwanted text content?

This is a new problem we just encountered today; the form was working just fine previously.

My form has a radio button that says

"Pre-registration $50". It's taking the hyphen as "negative," and adding -50 to the total field. Also I have drop down menus in the form of 1($12), 2($24), etc. It's taking the value to be $112, $224, etc., screwing up the calculation.

I guess I can change the format so that the relevant field contains just the values we want calculated, but I wonder if there is an alternative solution to this, since it did work before?

Demond SpraberryHow can I calculate a form with 6 questions and each question has a different value using a check box?

simonebrennanHi,

Can an 'average' function be added?

I can't simply add the values and divide, since options are 1, 2, 3, 4, 5, N/A. Currently a score of N/A affects the calculation (taking it as zero), when I want it to be ignored.

thescenedramaworksHow can I get the "other" field in the Radio Buttons options to be a numeric field?

JoannaHi,

I'm adding up fields in the form to calculate the total amount. The math works great but I would like to see a dollar sign in front of the result. $50, instead of 50. The calculation widget does not let me add any extra characters. Any ideas???

seajj2I am trying to plug in this formula (quantity x 10 + 6). The formula works but in the calculation it automatically has the 6 in the total. I do not want it to show anything until they put in the quantity. How do I perform this?

WOTI cannot get this calculation tool to work.

1. The fields I need to add are text boxes labeled "Points max20" and so on. The fields I am offered in the calculation wizard are labeled something different.

2. I've inserted the fields, + sign as shown in the example, but the values are not calculating.

Am I missing something? Please help!

escarecardI'm trying to calculate a series of inputs with predefined inputs of 0-12. When calculating, the form seems to see 0 as 1, 1 as 2 even though the calculation values are set as 0-12.

Is the form calculation unable to recognise a zero value?

Thanks!

Andreé possivel calcular valores dos inputs dentro da Matriz criada?

astankiewiczSo this functions is only for the form itself and can not be done on the dashboard at all - correct?

My purpose here is this: to make it so 5 viewers of the form results can rate the response from the form on the dashboard.

My Solution using these tools: Each Response is viewed and rated by each judge - the calculation field is recalculated each time and the form is submitted by each judge with each new calculation.

End result each response has a a calculated rating on the dashboard.

Will this work?

Thanks

hmcdowellHello, I am trying to add Calculation field and its not working out like it should. When I click on the check box of the item that I would like to calculate, it does not input the correct amount. For example if the amount is listed as $30, in the calculation field is says my total is 300000000000.00. Not sure how to current this. You should be able to view the form here, https://form.jotform.me/53191348159460

globalwebHow can I get the calculator widget to ignore certain part of a dropdown value?

For example here are the values we plan to have:

$49 - 10 Leads

$99 - 25 Leads

etc.

It needs to use the dollar value for calculation, but ignore the total lead #.

Thank you.

thomasmccullaghIf I am using the form calculation widget, alongside the matrix dynamique how do I make sure it only calculates one column of the matrix.

ameliabuttressHi there! I have created a form with 24 questions. Each is answered with a radio button rating the answer from strongly disagree to strongly agree. I'd like to make it so that there is a different display depending on what answer is input - if someone agrees or strongly agrees with one of the items, I'd like to recommend they look at different material. I added values to the matrix but when I added the calculation field, it seems to add a bunch of zeros to the total. Including a link to the form for review: https://form.jotform.us/71796041502150

How do I get rid of these extra zeros?

tipiThe checkbox show empty decimal from the option menu has no effect on the calculated value. Also the option swap dot for a comma has no effect, it will always show a dot as a separator. For accounting calculations it is important to show the empty values such as 457,00 € and also here in europe it would be nice to have the comma instead of a dot. any idea why both checkboxes have no effect?

thanks in advance

espleykI am completely bewildered. For each question in my quiz there is a yes or no answer and depending on each question I have put in a score of 0 or 1.

I have added the form calculation wizard and added a calculation for each question, but I don't think that's right! But I still can't get it to add it all up. I want to do a conditional logic for the thank you page which gives them a response that depends on the total scored. But when I go to the conditions menu to add conditional logic on the thank you page - I don't have a line that says - Total sum like you have in your example. How do I get a total score at the end in order to then be able to add this conditional logic. Thank you

I have a calculation that works until I add in "level of activity" which is a radio button. The entire calculation up to that point should be multiplied by the value associated with each answer. Somehow the answer comes in lower than it should be.
