How to Calculate Average Rating Scores & Use Conditional Logic in Gravity Forms

Last updated: August 16, 2026 β€’ Author:
Table of Contents

Beyond collecting simple feedback, the Gravity Forms Star Rating Field Addon empowers you to use rating values dynamically inside form calculation formulas and conditional logic workflows.

Powerful Use Cases

  • Automated NPS / Satisfaction Index: Average scores across multiple departments or service questions automatically upon submission.
  • Conditional Follow-Up Questions: If a customer rates below 3 stars, dynamically display a textarea asking “How can we improve your experience?”
  • Smart Redirects & Review Routing: Automatically redirect 5-star raters to Google Reviews or Trustpilot to generate public social proof.

Configuring Calculations & Logic

Step 1: Using Rating Values in Formulas

Add a Number field or Calculation field to your form. In the formula box, reference your star rating merge tags directly: ({Service:1} + {Product:2} + {Support:3}) / 3.

Step 2: Triggering Conditional Logic

On any follow-up field or submit button, enable Conditional Logic: set condition to Show this field if [Star Rating] is less than [3].
