In the financial world, trust is everything. Whether you're a trader looking for a broker or a fintech comparing service providers, reviews and ratings shape decisions. But not all review scores are created equal.
On TrustFinance, the TrustScore is more than a simple average—it’s a statistically balanced rating that accurately reflects a company’s credibility based on real customer experiences. Here’s how it works and why it matters to both consumers and financial institutions.
What is TrustFinance TrustScore?
The TrustFinance TrustScore is a numerical rating that reflects the credibility and trustworthiness of financial service providers. It is calculated using a method called the Bayesian average, which considers both the quality and the quantity of reviews to prevent manipulation by a few extreme ratings.
This score is vital for users comparing brokers, banks, fintechs, and investment firms, helping them make informed decisions based on verified client feedback.

How is TrustScore Calculated?
TrustFinance uses the Bayesian average instead of a simple arithmetic mean. This protects the score from distortion caused by a small number of extreme ratings (e.g., one 5-star or one 1-star review).
Bayesian Average Formula
R = Average review score of the company
v = Number of reviews received by the company
C = Minimum review count used as a comparison baseline (currently = 25)
m = Platform-wide average score (currently = 2.5)
This formula balances the company’s actual score with the platform’s average until the company has enough reviews to stand on its own.
Why Use the Bayesian Average?
The Problem with Simple Averages
If a company has 5 reviews with all 5 stars, it would appear “perfect.” But is that fair compared to another with 200 reviews averaging 4.3?
The Bayesian Fix
Companies with fewer reviews are adjusted toward the platform average (currently 2.5).
Scores gradually reflect actual performance as more reviews are received.
Large companies retain more stable, deserved ratings.

Comparison: Arithmetic vs Bayesian Averages
| Company | Total Reviews | Arithmetic Avg | Bayesian Avg (adjusted) |
|---|---|---|---|
| A | 10 reviews | 5.0 | 3.21 |
| B | 500 reviews | 4.5 | 4.41 |
| C | 1000 reviews | 4.4 | 4.36 |
Companies with few reviews are adjusted downward for fairness, while companies with a large number of reviews retain their calculated averages.
