**1. Create a calculated field**

Insert a calculated field in your form by typing

`/calculated field`

.- Name your calculated field, to easily retrieve it in calculations later on

- Choose whether the value will be
**text or a numeric value**

- Then add an
**initial value**as a starting point of your calculation. This can also be zero or left blank.

**2. Insert conditional logic**

The value of a calculated field gets calculated by using conditional logic. Type

`/logic`

to insert conditional logic.**The calculate action**

Conditional logic allows you to perform multiple actions. When using calculated fields, we want to select the

`Calculate`

action.You can perform numeric and textual operations with the Calculate action.

**Numeric operations**

- Add a value

- Subtract a value

- Multiply with a value

- Divide with a value

**Textual operations**

- Assign: add a text value (for example ‘hot lead’)

- Concatenate values: combine values in one string

Calculations on date blocks are not available yet

**An example**

In this example the respondent can choose between 2 products. When the respondent chooses "Apple" we want to add $2 to our calculated field (the price). When the respondent chooses "Pear" we want to add $3.

- Add conditional logic using the
**Calculate function**: **When**the answer to the question**Choose a product****contains**the answer**Apple ($2)**- Then
**Calculate**our calculated field**Price**and**Add+**the value of**2**

- Repeat this for the answer option
**Pear ($3)**

**3. How to use calculated fields**

Calculated values are not by default visible in your form. You can find them in the

**results tab**of your form, but you can also choose to**display**the calculated values in your form, use them in a payment form, or to create a dynamic redirect on completion.**Display a calculated field in your form**

To mention your calculated value in your form, simply type

`@`

and choose the calculated field from the dropdown menu. You can use this to show a final price, score or quiz result in your form.**Dynamic pricing in a payment form**

You can use a calculated field to

**calculate the price of your payment form**and make it dynamic based on the answers of your respondents.- Insert a payment form

- Choose your calculated field from the Price dropdown menu in your payment block

- The price will now automatically and in realtime be updated according to your respondent's answers

**Dynamic redirect on completion**

Use calculated fields to redirect respondents to different landing pages, based on their responses. You can do this by using a calculated field as your Redirect on completion link.

- Insert a
`calculated field`

and name it (for example: URL).

- Insert
`Conditional logic`

and assign a URL based on your conditions.

In this example we want to redirect respondents that choose "Pricing" to the landing page "acme.inc/pricing" and respondents that choose "News" to the landing page "acme.ince/blog" when they submit the form.

- Go to form settings →
`Redirect on completion`

, click or type`@`
