This is one of the most commonly asked questions about CIBIL scores in India.
The FICO Score Model Connection
The CIBIL scoring model is adapted from the FICO (Fair Isaac Corporation) scoring model, which is the global standard for credit scoring. The FICO model uses a range of 300 to 850 in the United States. When TransUnion CIBIL designed India's credit scoring system, they adopted a similar starting point, i.e. 300, rather than beginning from 0.
There are two primary reasons:
- Statistical Design Choice: Credit scores are not absolute rankings. They are statistical probability models. The range from 300 to 900 was chosen because it allows enough spread to meaningfully differentiate borrowers at every risk level.
- Scores Below 300 are Statistically Irrelevant: Credit scoring algorithms are trained on historical borrower data. After analysing the multiple credit profiles, TransUnion CIBIL determined that no meaningful statistical differentiation exists below 300.
