Median star rating calculator

Find the middle rating from a distribution of one- to five-star reviews.

Model estimate, not a platform prediction. Results may differ from real service ratings. Platforms can use unpublished weights, moderation, eligibility rules and rounding. This calculator applies only the formula below.

Median star rating · model result
5.000 / 5

Middle rating of 100 reviews, ordered from 1 to 5 stars.

Results are rounded to three decimal places.

How it works

Middle ordered rating; for an even count, average the two middle ratings.

The median can remain unchanged even when many reviews change. It describes the middle of the distribution and does not reproduce a platform’s displayed average.

Results update as you type. Calculations run in your browser; submitting with JavaScript disabled sends the numbers to the server to calculate the result.
