How to Calculate Star Ratings and Review Percentages on Amazon
In the world of eCommerce, customer reviews act as a beacon of trust and credibility for potential buyers. Among all the factors influencing your buying decision, star ratings play a vital role. But how does Amazon calculate these ratings? This article aims to unveil the underlying methods of calculating overall star ratings and the percentage breakdown by star, enabling you to be an informed shopper.
Understanding Star Ratings
Star ratings are a critical aspect of product evaluation on platforms like Amazon. A product’s star rating can significantly influence its sales. Generally, the ratings range from one star (poor) to five stars (outstanding).
What Constitutes a Star Rating?
The star rating system on Amazon is not just a straightforward average of reviews. Instead, it incorporates various factors, ensuring that quality and relevance have a significant impact.
Why Isn’t It Just an Average?
Calculating the average of ratings could be misleading. For example, if a brand-new product receives a few five-star ratings followed by a wave of one-star reviews once it’s more widely adopted, a simple average may not accurately reflect customer satisfaction.
Factors Influencing Star Ratings
1. Recency of Reviews
Recent reviews hold more weight than older ones. This means if you purchase a product and leave a five-star review, it may boost its rating more than a five-star review left six months ago.
2. Verified Purchases
Only reviews from customers who have verified their purchase through Amazon are taken into account for the overall rating. This ensures genuine reviews inform the rating rather than those circumventing the purchase.
3. Review Analysis and Trustworthiness
Amazon employs complex algorithms to analyze reviews. A review marked as trustworthy by multiple users may carry more significance than others. They look for patterns in the language used and the sentiment behind the reviews.
How is the Percentage Breakdown Calculated?
1. Breakdown by Stars
Amazon provides a percentage breakdown of how many one-star, two-star, three-star, four-star, and five-star ratings a product receives. This breakdown is critical for a potential buyer, giving a more nuanced view of how people feel about a product.
2. Weighting System
The weighting system plays an important role in how these percentages are displayed. The percentages dynamically change based on the recency and trustworthiness of reviews, which keeps the rating relevant and reflective of current user experiences.
Pros and Cons of Amazon’s Review System
Pros
- Transparency: The review system allows buyers to see a detailed breakdown of reviews.
- Trust: Verified purchase indicators add a layer of trust, steering clear of fake reviews.
- Continuous Updates: Real-time updates to ratings ensure that current buyer sentiment is considered.
Cons
- Subjectivity: Star ratings can sometimes be based on individual expectations and experiences.
- Manipulation Risks: Despite the safeguards, there’s always a risk of false reviews influencing ratings.

The Role of Reviews in Consumer Behavior
Why Are Reviews Essential?
Customer reviews often serve as the final nudge for indecisive buyers. Over 90% of consumers read online reviews before making a purchase.
How to Assess Reviews Effectively?
When evaluating a product, consider factors beyond the star rating. Look at the content of reviews, how many reviews are verified purchases, and whether the reviewer mentions specific features that matter to you.
Conclusion
Understanding Amazon’s star rating and review system equips you with the knowledge to make informed purchasing decisions. The intricate calculation of these ratings not only reflects customer sentiment effectively but also puts significant emphasis on the recency and validity of the reviews. With this insight, you can navigate customer feedback with greater confidence.
