Credit scores are based on multiple models. However, two of them are most commonly used worldwide. These models are as follows:
FICO CREDIT SCORE MODEL
This credit model estimates your credit score on a fixed range of 300-850 where 300 represents the minimum or lowest credit score, and 850 represents the highest or the best credit score. Most commonly use, many mortgage lenders use FICO scores to determine whether a mortgage applicant qualifies for one or not. While applying for your FICO score, you can choose from three different bureaus. Each bureau uses a different sub-model to calculate FICO scores, so choose one that best fits your needs.
