Finance Manager web application written in HTML, CSS, and JavaScript.
A clean and modern browser-based investment simulator for calculating compound growth, tracking portfolio allocation, and planning financial independence.
- Portfolio tab displays asset allocation as interactive pie, bar, and donut charts.
- Projection tab calculates and visualizes the investment growth timeline with an interactive line chart and a today marker.
- Saved Scenarios tab stores multiple projection scenarios for side-by-side comparison, each with independent inflation mode settings.
- Simulates compound interest growth with configurable annual return rate, initial principal, and regular contributions (daily, weekly, monthly, or yearly).
- Supports inflation adjustment in two modes: local currency inflation and foreign currency inflation.
- Supports foreign exchange (FX) simulation — calculates growth in a foreign currency with configurable exchange rate, annual rate increase, and foreign inflation.
- Three target types: principal target, income target, and time target.
- Each saved scenario shows a detailed modal with nominal values, real values, and today's money adjusted figures.
- Written in HTML, CSS, and JavaScript.

- The user interface is in Turkish.
- Data is persisted locally in the browser via
localStorage. - All external dependencies (Chart.js, chartjs-plugin-datalabels, chartjs-plugin-annotation, Inter font) are bundled locally — no internet connection required.
