How is the average rating calculated from star counts?

The tool uses a weighted average formula: multiply each star count by its star value, sum those products, and divide by the total number of votes. This produces a rating between 1 and 5 that reflects the distribution of all entered counts.

Can I use this tool for rating systems that use more than 5 stars?

No, the calculator is designed specifically for 5-star review distributions. Entering counts for a different star range will not produce a meaningful average within this tool.

What does the percentile result mean?

The percentile shown indicates the percentage of possible ratings that are equal to or lower than the calculated average, based on the distribution of the counts you entered.

Do I need to create an account to use the Average Rating Calculator?

No account or subscription is required. The tool is free to use and the page is publicly accessible without registration.

About this tool

What Average Rating Calculator does

The Average Rating Calculator on Calculator Academy lets users enter the count of ratings received at each star level—from one to five—to compute a weighted average score, total votes, and related metrics such as percentile. The result shows the calculated average rating alongside the number of votes that contributed to it. The site provides the underlying formula and worked examples to help users understand how the average is derived from the star distribution. The tool is free to use with no subscription required, and the page is publicly accessible. The Calculator Academy version distinguishes itself by displaying the formula and step-by-step examples directly on the page, allowing users to see exactly how their input counts translate into the final average. While other tools for the same task also compute a weighted average from 1–5 star counts, Calculator Academy’s interface presents the math and sample calculations openly, making it easier for users to verify the result or learn the method. The tool requires no sign-up or payment, and it focuses specifically on 5-star review distributions without additional clutter.
