Webflow allows you to create a custom online formula calculator without coding by using its built-in Designer, CMS, and third-party integrations like Formulas in Webflow Logic or third-party tools like Jetboost, Outseta, or Make (formerly Integromat). Here’s how:
- Add a Webflow Form to collect user inputs (e.g., values for a pricing calculator, BMI calculator).
- Use text inputs, dropdowns, or sliders depending on the required input type.
- Assign unique IDs or name attributes to these fields for integration with external tools.
2. Utilize Webflow Logic (Beta) for Basic Calculations
- Webflow’s Logic feature (Beta) allows simple conditional calculations.
- Create workflow rules to perform calculations based on form inputs.
- Webflow currently lacks native arithmetic functions, but you can send data to external tools for processing.
If you need more complex logic, integrate external no-code tools such as:
- Make (formerly Integromat) – Automate calculations and return results dynamically.
- Zapier – Sends input data to Google Sheets, performs calculations, and returns results.
- Outseta or Jetboost – Handle dynamic calculations with membership or filtering capabilities.
4. Display Results Dynamically in Webflow
- Use hidden input fields inside your Webflow form to receive calculated results.
- Inject calculated values into a Webflow CMS collection, which updates in real time.
- Alternatively, use JavaScript-Free Embed solutions like Outseta’s calculators or Make’s API handling to show results instantly.
- If calculations require spreadsheets, embed a live Google Sheets document in Webflow.
- Users enter values in a Webflow form, which updates a connected Google Sheet, and results are displayed using third-party integrations.
Summary
With Webflow’s Forms, Logic, and third-party tools like Make or Zapier, you can build a simple formula calculator without any coding. If you need advanced calculations, consider external API-based solutions like Google Sheets or Outseta.
