-# investment-portfolio-simulator
-Portfolio Simulator for Investing, using real data provided by yahoo finance with sleek modern Design. 
+# Investment Portfolio Simulator
+
+A modern web application for simulating and tracking investment portfolios with real-time data. Built with React, TypeScript, and Tailwind CSS.
+
+Why this Project?
+- I wanted to see how my portfolio would perform if I had invested in something else, and thus with savings plan(s)
+- The main issue with other saving-plan calculators is, that they calculate based on the p.a. performance, i wanted further insights however, and thus this projected was created.
+- It allows you to see how single-investments and savings plans would have performed, and how they would have affected your portfolio.
+- There are multiple indicators and design choices made:
+  - TTWOR (Time Travel Without Risk) calculations
+  - Average Portfolio Performance
+  - Portfolio Performance & Value
+  - All assets (except the TTWOR and Portfolio-Value) are scaled by percentage of their price. Thus their referenced, scale is on the right. The referenced scale on the left is only for the portfolio-value
