Form Calculator

You can start performing calculations through your form fields with this easy to use, yet powerful calculator.

You can use different field types for your calculations and also setup chain calculations, for example the sum of the fields can be used as a variable for your next calculation.

First we will need to add the fields that be will part of our calculations. In our first example we will use general operators like adding, substracting, multiplying and dividing.Let see how we can build our first calculation with Kali Forms.

Adding the fields and total

After the fields are added we will need to start defining our calculation equations. This can be done by navigating to the Calculator tab in your form configuration.

Adding the fields and total

Your calculations can be added in two ways:

  • 1. With the help of our Math helper

    This will open a dialog box at the bottom of the screen, all you need to do is:

    • Set the calculation type Select type of calculation
    • Select the total field Select the total field
    • Choose the fields that will be used in the calculation Select fields for calculation

When using the Math helper feature you have several functions available that will allow you to perform operations.

Name Operation performed
Sum of selected fields Adds up the fields your select.
Subtract two fields Subtracts the second field from the first field.
Divide two fields Divides the first field by the second field.
Multiply selected fields Multiplies the fields you select.
Arithmetic average of fields The sum of all of the numbers in a list divided by the number of items in that list.
BMI Formula(imperial) Divide your weight (lb) by your height (in), divide the result by your height again, then multiply your answer by 703.
BMI Formula(metric) Divide your weight (m) by your height (kg), divide the result by your height again.
Minutes to seconds Converts minutes to seconds.
Seconds to minutes Converts seconds to minutes.
Seconds to hours Converts seconds to hours.
Minutes to hours Converts minutes to hours.
Hour:Minute:Seconds to seconds Convers the time with the format mentioned above to seconds.
Speed Calculates the speed by dividing the distance with the time it took to complete it.
Running pace This divides the total time by the distance you ran.
Running time Calculates the total running time by multiplying your total distance with your pace.
Running distance Calculates the distance by dividing the total time by your pace.
Day difference between dates Calculate the number of days between your chosen dates.
  • 2. By directly writing the ecuation in the designated calculations area

    This will allow you to create your own calculations by writing the equations manually. You can also add comments in the editor so that you can better structure your calculations for later edits.

    Manually enter the calculation
