How to Generate Synthetic Datasets for Credit Card Default Prediction?
Synthetic data is at the forefront of solving data-related problems, and generating synthetic data is easier than you think…
In banking and finance, credit card default prediction datasets are important. They’re used to train AI models that assess the risk of clients missing their payments, for building credit risk models, underwriting loans, and improving financial decision-making.
If you’re developing a credit default prediction model, you’ll need diverse, high-quality data; but as you might be aware that real financial data often comes with privacy risks and regulatory restrictions. That’s where synthetic data generation helps.
To generate a synthetic dataset for credit card default prediction, follow the simple steps outlined below. Or, you can jump right in by exploring our ready-to-use synthetic credit card default dataset on GitHub.
Let’s dive in!
How to Generate Synthetic Data for Credit Card Default Datasets?
If you want a privacy-safe credit risk modeling synthetic dataset, you have two main options in 2025:
A) Traditional Synthetic Data Generation Method
Step 1: Start with real or sample data (if available). First, analyze existing credit default datasets to understand features such as demographics, credit limits, repayment histories, and default patterns. This will give you insight into realistic data distributions.
Step 2: Now, define features. Identify attributes to model by including client age, sex, education level, marriage status, past payment statuses, bill amounts, repayment amounts, and the default label.
Step 3: Next, choose a generation method. Here are a few options:
- Statistical sampling that mimics real data distributions
- Rules-based methods encoding domain knowledge
- Generative AI models such as Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), or GPT-based models that learn patterns from real data and create realistic synthetic samples
Step 4: Now, set up the process and start generating synthetic data. Validate it by checking statistical properties (mean, variance, etc) and ensure the appropriate balance between default and non-default cases.
Step 5: Finally, test & deploy. Use the dataset to train, evaluate, and benchmark credit risk prediction models.
B) Using Synthetic Data Generation Tool
You can generate synthetic data in 2 minutes with platforms like Syncora.ai
- Upload raw or existing credit data (structured or unstructured)
- AI agents clean, structure, and synthesize data patterns rapidly while preserving statistical properties and applying privacy measures.
- Download ready-to-use synthetic credit card default datasets in formats like CSV or JSON. That’s it!
Get a Privacy-safe Synthetic Dataset for Credit Card Default
Our synthetic credit card default dataset is available on GitHub and offers a comprehensive collection of over 50,000 fully synthetic records from Taiwan, and is designed for credit risk modeling and AI development. It simulates real-world credit card client behavior while preserving privacy and removing any sensitive information. You can download it below
Features of this Dataset are:
- Demographics: Age, gender, education, and marital status of clients.
- Payment History: On-time or delayed payments over the past 7 months.
- Billing Amounts: Monthly charges for the last 6 months.
- Payment Amounts: Amounts paid over the previous 6 months.
- Default Status: Indicates whether the client will default next month (1 = yes, 0 = no).
What are the Applications of Synthetic Financial Datasets for AI Use?
- AI teams can train machine learning models to predict if a client will miss their next payment.
- Analysts can explore data to find trends in client demographics and payment behavior.
- Data scientists can create new features from repayment patterns and credit usage to improve models.
- AI developers can use tools like SHAP or LIME to explain what drives default risk predictions.
- Teams can compare different algorithms like logistic regression or neural networks to find the best model.
- Risk managers can simulate different financial scenarios to see how models perform under stress.
- Educators can use this dataset to teach machine learning and credit risk concepts safely.
- Developers can build and test credit risk models while keeping client data private and compliant with regulations.
FAQs
Why should I use synthetic data instead of real credit card default data?
Synthetic data doesn’t have privacy risks and regulatory compliance issues since it contains no real client information. It allows safe experimentation, AI model training, and validation without exposing PII.
Can models trained on synthetic data perform well on real-world credit default prediction?
Yes, only if the synthetic data is generated accurately and preserves statistical properties and feature relationships. When models are trained on such data, they can achieve comparable performance to those trained on real data.
Is synthetic data legal and ethical to use in financial AI applications?
Yes, synthetic data complies with privacy laws such as GDPR because it contains no real personal identifiers, making it a legal and ethical choice for developing credit risk models.
In a Nutshell
Synthetic datasets make credit card default prediction safer, faster, and more accessible. They remove privacy risks while keeping the realism needed for accurate AI models. Whether you generate them manually or use tools like Syncora.ai, you can create high-quality, ready-to-use data for training, testing, and teaching credit risk models.
