Meet FinanzSim: My Educational Financial Management Simulator _An AI-powered web app I built to help business students master financial concepts through hands-on simulation._ --- ## What Is FinanzSim? **FinanzSim** is an interactive web-based simulator designed specifically for first-year Business Studies students. The application allows learners to experience the complexities of managing a company's finances across multiple years, making strategic decisions and observing their real-time impact on key financial indicators. Think of it as a sandbox where students can safely experiment with financial strategies, learn from their mistakes, and receive instant AI-generated feedback without any real-world consequences. --- ## Objectives I built FinanzSim with several clear goals in mind: 1. **Bridge Theory and Practice** — Transform abstract financial formulas into tangible, interactive experiences that students can explore hands-on. 2. **Develop Strategic Thinking** — Help students understand how decisions about pricing, costs, investments, and financing ripple through the entire financial structure of a business. 3. **Provide Instant Feedback** — Leverage AI to deliver personalised, real-time analysis after each simulated year, as if they had a virtual professor by their side. 4. **Demystify Financial Ratios** — Make complex metrics like ROA, ROE, liquidity ratios, and leverage accessible through visual dashboards and clear explanations. 5. **Encourage Experimentation** — Create a risk-free environment where making mistakes is part of the learning journey. --- ## How It Works ### Getting Started 1. **Choose Your Timeframe** — Select how many years you want to simulate (from 1 to 12 years). 2. **Start with Initial Capital** — Your company begins with a treasury of **100,000 €**. ![Selección de años y capital inicial](https://media.carlosluengo.com/blog/finanzsim/finanzsim2026_02-3d92479158-1564.webp) ### Year-by-Year Management For each simulated year, you'll make key business decisions: | Decision | Description | | ------------------- | -------------------------------------------------- | | **Units Sold** | How many units of product you expect to sell | | **Unit Price** | Your selling price per unit | | **Variable Costs** | Cost per unit produced | | **Fixed Costs** | Overheads that don't change with production volume | | **New Investment** | Capital expenditure on assets | | **New Loans** | Additional debt financing | | **New Equity** | Fresh capital injection | | **Collection Days** | How long customers take to pay you | | **Payment Days** | How long you take to pay suppliers | ![FinanzSim annual decisions panel](https://media.carlosluengo.com/blog/finanzsim/finanzsim2026_03-13cd864b23-1564.webp) ### Real-Time Financial Analysis After submitting your decisions for each year, FinanzSim calculates and displays: - **Income Statement** — Revenue, EBIT, EBT, Net Income - **Balance Sheet** — Assets, Liabilities, Equity - **Break-Even Analysis** — How many units you need to sell to cover costs - **Key Ratios** — ROA, ROE, Leverage, Liquidity, Solvency - **Cash Flow** — For NPV calculations - **Working Capital Cycle (PMM)** — Storage, manufacturing, sales, and collection periods ![FinanzSim real-time financial analysis view](https://media.carlosluengo.com/blog/finanzsim/finanzsim2026_04-a4fa315664-1564.webp) ### AI-Powered Professor Feedback Here's where it gets interesting! After each year, an **AI professor** analyses your results and provides: - Commentary on your financial performance - Identification of potential risks - Suggestions for improvement - Comparison to typical business benchmarks --- ### Final Executive Report Once you complete all simulation years, you can generate a **comprehensive executive report** that includes: - Full performance analysis across all periods - Net Present Value (NPV) of your company - AI-generated strategic summary and recommendations - Visual charts showing business evolution --- ## Tech Stack I built FinanzSim using a modern, performant tech stack: ### Frontend | Technology | Purpose | | -------------- | ---------------------------------------------------- | | **React 19** | UI component library with hooks for state management | | **TypeScript** | Type-safe development with enhanced IDE support | | **Recharts** | Beautiful, responsive charts for data visualisation | | **Vite** | Lightning-fast development server and build tool | ### Backend & AI | Technology | Purpose | | ---------------------- | ----------------------------------------------------- | | **Cloudflare Workers** | Serverless edge computing for the API | | **Cloudflare Pages** | Global CDN deployment | | **Google Gemini API** | AI-powered financial analysis and feedback generation | ### Deployment | Technology | Purpose | | ------------ | ----------------------------------------------- | | **Wrangler** | Cloudflare's CLI for managing Workers and Pages | | **Git** | Version control | --- ## About the Project FinanzSim is a **research pet project** developed in collaboration with the _Faculty of Economics, Business and Tourism_ at the **University of Alcalá (UAH)** in Spain. The aim is to explore how AI-enhanced interactive simulations can improve financial literacy amongst university students, making complex concepts more approachable and engaging. --- ## Disclaimer This application is an **educational simulator with no commercial purposes**. The AI-generated analyses are orientative and do not constitute professional financial advice. I am not responsible for misuse of the information, errors in AI responses, or service availability. --- ## Final Thoughts Building FinanzSim has been an incredibly rewarding experience. Combining my passion for education technology with practical financial concepts has created something that I genuinely believe helps students learn. If you're a student, educator, or just curious about business finances, I'd love to hear your feedback! --- Author: Carlos Luengo Vera — https://carlosluengo.com/about
