Calculatable fields
Definition: Calculatable fields are fields within a web form that automatically compute values based on user input in other fields. This allows dynamic calculations (such as totals, taxes, or custom quotes) to be displayed in real time, improving accuracy and user experience.
Key Features:
- Real-Time Calculations: Automatically compute values (e.g., totals, discounts, taxes) as users enter data.
- Custom Formulas: Support mathematical operations (+, −, ×, ÷) and grouping to tailor complex calculations like pricing models or scoring.
- Dynamic Field Referencing: Use values from number, product, or choice fields (including checkboxes and dropdowns) in calculation formulas.
- Versatile Use Cases: Applicable to order forms, estimators, quizzes (e.g., BMI, scores), and financial or tax calculators.
Significance: Calculatable fields elevate forms beyond static input by delivering immediate, accurate results to users and reducing manual errors. They streamline workflows – whether for commerce, assessments, or data collection – by automating computations. Their versatility allows form builders to embed logic previously reserved for spreadsheets directly into form interfaces.
Use Cases:
- E-commerce Order Forms: Automatically calculate product totals, apply taxes, shipping, and discounts as users make selections.
- Service or Quote Estimators: Compute estimates for things like area-based pricing, custom services, or event planning based on user inputs.
- Scoring and Surveys: Use calculated fields to derive quiz scores, assessment results (e.g., BMI), or rating totals from multiple user responses.
