Financial institutions have a large amount of information about how clients act and their credit history. This data in its raw form is not useful for making correct decisions, requiring an accurate system to differentiate between solvent clients and those at risk. of non-payment. The purpose of this research was to create a fuzzy logic model to minimize credit risk in personal loans in financial institutions. A base set of basic fuzzy rules was designed to provide a framework in which expert knowledge and data can be used for risk modeling. The study was carried out using a pre-experimental design, with an evaluation before and after the intervention in a single group. A sample of 358 clients was used, extracted from a population of 5,000 clients from a dataset provided by the Kaggle platform. In this research, a personal loan application evaluation model was developed that uses fuzzy logic using Python to serve as decision support to determine the creditworthiness of the applicants. The model was validated in terms of accuracy and efficiency.
