Description
Bank Bang Bang is an AI-powered wealth planning assistant that helps individuals simulate and achieve financial freedom — bringing private banking capabilities to everyone.
Users simply input their age, income, spending, and retirement goals. The system projects their future savings timeline, runs two investment simulations —
an Aggressive Mode using S&P 500 ETF growth modeling via Monte Carlo simulation, and
a Conservative Mode assuming a steady 8% annual dividend yield.
The tool visualizes wealth accumulation, forecasts passive income after retirement, and evaluates whether users can sustain their lifestyle. Finally, Gemini AI generates personalized financial advice, offering tailored saving or spending recommendations.
By combining data analytics, market simulation, and generative AI, Bank Bang Bang empowers everyone — not just the wealthy — to plan, invest, and reach financial independence with confidence.
