This report provides an in-depth analysis of customer churn at a bank, utilizing key performance indicators (KPIs), demographic insights, and customer segmentation to understand the factors driving churn. The analysis leverages customer data from Germany, France, and Spain, focusing on credit scores, estimated salaries, account tenures, and other critical variables. The findings offer strategic recommendations aimed at reducing churn, improving customer retention, and enhancing the overall profitability of the bank.
Customer churn is a critical concern for financial institutions, directly impacting revenue and long-term profitability. Understanding the attributes that distinguish churned customers from loyal ones is essential for developing effective retention strategies. This report aims to:
Before delving into the analysis, it was essential to clean and prepare the raw data for accurate insights. The original dataset contained inconsistencies such as varying geography names, currency formatting issues, duplicate entries, and lacked crucial indicators like churn status and customer segmentation.
Steps Taken:
These steps transformed the dataset into a clean and structured format, making it suitable for in-depth analysis.
The credit score distribution between churned and non-churned customers shows a slight skew towards higher scores among non-churners. However, the overlap suggests that credit score alone may not be a decisive factor in predicting churn. This finding indicates the need to consider other variables in conjunction with credit scores to build a more accurate predictive model.
Churned customers tend to have slightly higher estimated salaries compared to non-churners. This trend suggests that higher-income customers may have different expectations or face different financial pressures that lead to churn. Understanding the underlying reasons for this trend could inform strategies to better engage and retain high-income customers.
Germany has the highest customer representation, followed by France and Spain. This distribution is crucial for understanding regional differences in customer behavior and tailoring retention strategies accordingly.
German customers have the highest average credit scores, followed by Spain and France. The higher credit scores in Germany suggest a potentially more stable customer base, which may require different retention strategies compared to regions with lower credit scores.
Germany also has the highest average age and estimated salary, suggesting that German customers are generally older and more financially established. In contrast, France has the highest average estimated salary, while Spain has the lowest. These demographic differences highlight the need for region-specific approaches to customer engagement.
The clustering algorithm identified five distinct customer segments based on tenure, credit score, age, and estimated salary:
Each segment has unique characteristics that should inform targeted marketing and retention strategies. For example, Cluster 4, which includes young, high-income customers, may benefit from premium services and personalized financial advice, while Cluster 3, with low tenure and salary, might need engagement through loyalty programs and financial education.
The churn prediction model demonstrates moderate accuracy, with a slight edge in predicting churners over non-churners. However, both classes have close precision, recall, and F1-scores, indicating balanced performance.
This analysis provides a robust understanding of the factors influencing customer churn at the bank, with actionable insights for reducing churn and enhancing customer loyalty. By implementing the recommended strategies, the bank can not only improve customer retention but also strengthen its competitive position in the market.
