Retirement & 401k Calculator

Calculate your 401k growth, target retirement age, and monthly income privately.

The Retirement & 401k Calculator is a professional financial planning tool designed to show you exactly where your portfolio is heading, what your monthly income will be, and the exact steps to take if you are falling behind.

Whether you are 25 and just opening an IRA, or 55 and maximizing your 401k employer match, this tool gives you a crystal-clear, year-by-year roadmap to your target retirement date.

Core Planning Features:
• Your Retirement Outlook: Instantly see your projected portfolio balance versus your actual "Amount Needed" based on your desired monthly lifestyle.
• The 4% Safe Withdrawal Rule: Calculate your exact monthly take-home income from your investments during retirement.
• Actionable Gap Closing: If you are off-track, the app mathematically suggests how to fix it (e.g., "Save $100 more/month" or "Work 2 more years").
• Year-by-Year Projections: View a beautiful, interactive growth chart that visualizes the power of compound interest and employer matches over time.
• Compare Scenarios: Create and save up to 3 different "What-If" plans. Compare different expected returns, contribution increases, or earlier retirement ages side-by-side.
