Traditional models may not fully capture the complexities involved due to the multifaceted nature of insurance data. This paper explores the use of machine learning (ML) techniques to predict insurance charges, providing a more data-driven and potentially more accurate method compared to conventional approaches. We will analyze various machine learning models, evaluate their performance, and discuss their potential for use in insurance companies to enhance pricing accuracy and efficiency.  \nI. INTRODUCTION  \nInsurance companies determine the premiums that individuals or organizations must pay for coverage based on various factors such as age, gender, smoking status, health conditions, and more. These factors are highly diverse, and hence, predicting insurance charges involves significant complexity. Predictive modeling with machine learning provides an opportunity to analyze large datasets and uncover intricate patterns that would otherwise be difficult to detect. The objective of this paper is to demonstrate how machine learning can be leveraged to predict insurance charges, highlighting various methods and their respective performances.  \nII. DATASET DESCRIPTION  \nThe dataset used for this study contains a collection of insurance charges from a variety of individuals, with the following key features:  \n1. Age: The age of the individual.  \n2. Sex: The gender of the individual.  \n3. BMI: Body mass index of the individual.  \n4. Children: The number of children or dependents covered by the insurance.  \n5. Smoker: Whether the individual is a smoker (binary: Yes/No) .  \n6. Region: The geographical region the individual is located in.  \n7. Charges: The insurance charges (target variable) to be predicted.  \nIII. METHODOLOGY  \nMachine Learning Models  \nWe will explore the following machine learning algorithms to predict insurance charges:  \n1. Linear Regression (LR): A linear approach that assumes a straight-line relationship between independent variables and the target variable.  \n2. Decision Tree Regressor (DTR): A tree-based method that splits the data into subgroups and predicts the target variable based on these splits.  \n3. Random Forest Regressor (RFR): An ensemble of decision trees that improves predictive performance by reducing overfitting.  \n4. Support Vector Regressor (SVR): A method that tries to find the hyperplane that best fits the data, suitable for non-linear relationships.  \n5. Gradient Boosting Regressor (GBR): An ensemble method that builds models sequentially to improve performance.  \nIJIRSET©2025 | An ISO 9001:2008 Certified Journal | 1460  \n\n| |[www.ijirset.com](www.ijirset.com |A Monthly)[ |A Monthly](www.ijirset.com |A Monthly), Peer Reviewed & Refereed Journal| e-ISSN: 2319-8753| p-ISSN: 2347-6710|\u003Cbr>Volume 14, Issue 2, February 2025\u003Cbr>|DOI: 10.15680/IJIRSET.2025.1402067|\u003Cbr>Evaluation Metrics\u003Cbr>The following metrics will be used to evaluate the performance of each model:\u003Cbr>• Mean Absolute Error (MAE)\u003Cbr>• Mean Squared Error (MSE)\u003Cbr>• Root Mean Squared Error (RMSE)\u003Cbr>• R-squared (R²)\u003Cbr>IV.
