Calculated Field

Introduction to Calculated Fields

The Calculated Field feature in MakeForms is designed to perform automatic calculations based on the inputs provided by the form users. This episode will guide you through setting up a simple interest calculator, demonstrating how you can utilize this feature to add dynamic and interactive elements to your forms.

How to Set Up a Simple Interest Calculator

Step-by-Step Guide:

1. Adding Input Fields:

   • Begin by adding essential fields to your form: a Number Field for the principal amount, another Number Field for the rate of interest, and a Slider to select the number of years. These fields will serve as the basis for our calculations.

2. Configuring the Slider:

   • The Slider for the number of years should have a minimum value of 1 and a maximum value of 20, with a step increment of 1 year. This allows users to easily select the loan duration.

3. Creating the Calculated Field:

   • Search for and add the Calculated Field to your form. Name this field “Total Interest” to indicate its purpose.
   • In the formula section, input the calculation formula to determine the total interest payable over the selected period. This will typically involve multiplying the principal amount by the rate of interest and the number of years, then dividing by 100 to get the total interest.

4. Customizing Field Options:

   • Utilize placeholder text to guide users, e.g., “Your total interest will appear here.”
   • Add helper text or tooltips to provide additional information about the field, such as “Total interest that you will pay.”

5. Finalizing and Testing Your Calculator:

   • After setting up the calculation logic, preview and publish your form to test the calculator’s functionality. Enter different values to ensure the calculated total interest updates accurately based on the inputted principal amount, interest rate, and duration.
