Instead of using a single fixed rate of return, it:\n\n1. Runs 1,000 different scenarios\n2. Each scenario uses random returns from your specified range\n3. Tracks how many scenarios result in successful retirement\n4. Calculates a success rate based on these simulations\n\nThis approach provides a more realistic view of retirement outcomes by accounting for market volatility and various economic factors.\n\n### Calculation Methodology\n\nThe calculator performs two main phases of calculations:\n\n#### Accumulation Phase (Pre-Retirement)\n\n- Applies investment returns to current savings\n- Adds monthly contributions\n- Adjusts for inflation\n- Accounts for taxes on investment gains\n\n#### Retirement Phase\n\n- Calculates retirement expenses with inflation adjustment\n- Includes Social Security benefits when eligible\n- Applies investment returns to remaining savings\n- Accounts for taxes on withdrawals\n\n### Success Rate\n\nThe success rate indicates the percentage of scenarios where your savings last through retirement:\n\n- ≥80%: Strong retirement plan (Green)\n- 60-79%: Moderate risk (Yellow)\n- \u003c60%: High risk (Red)\n\n## Local Development Setup\n\n1. Clone the repository:\n\n   ```bash\n   git clone [repository-url]\n   cd retirement-calculator\n   ```\n\n2. Install dependencies:\n\n   ```bash\n   npm install\n   ```\n\n3. Start the development server:\n\n   ```bash\n   npm run dev\n   ```\n\n4. Open http://localhost:5173 in your browser\n\n---\n\nThis project was an exercise to learn about the Monte Carlo Simulation method. What it does, How it works, and how to use it. Speak to a professional financial planner if you are serious about retirement planning. The calculator is not intended to be a substitute for professional financial advice.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbittricky%2Fretirement-calculator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbittricky%2Fretirement-calculator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbittricky%2Fretirement-calculator/lists"}
