Inspiration
Our inspiration for this project comes from our own experiences navigating the confusing world of vehicle financing. We often had to manually track our real cash flow and analyze our bank accounts just to understand whether a financing quote was truly a good or bad decision.
What it does
This tool essentially collects key household-level (microeconomic) inputs from the user — such as budget, lifestyle patterns, preferred loan terms, and financial comfort levels — and applies financing guidelines to determine the best options. It analyzes the user’s needs, goals, and constraints to provide transparent, personalized recommendations that prioritize long-term financial well-being.
How we built it
We leveraged software to integrate targeted financial models with microeconomic factors, our system generates efficient, data-driven outputs that reflect real-world affordability and consumer behavior.
Challenges we ran into
Our biggest challenge in this project was determining how to model the adaptive APR function and identifying which household-level microeconomic variables would meaningfully influence it.
Accomplishments that we're proud of
Successfully designing and modeling the Adaptive APR function
What we learned
Throughout this project, we learned how AI can complement financial modeling, not just as a chatbot but as a real analytical assistant. We deepened our understanding of how to merge behavioral finance, microeconomics, and modern AI frameworks to create transparent and responsible financial tools.
What's next for toyota website
We envision Toyota integrating our tool as a floating, interactive widget on the main website — giving customers real-time guidance and helping them make informed, confident financing decisions.
