RunMyWealth

Traditional financial calculators are broken. They bombard you with ads, force you to create an account just to see your results, or ask you to link your bank account—creating massive privacy risks for simple math.

RunMyWealth solves this by providing a comprehensive suite of 8 powerful financial planning tools that run 100% in your browser. Because the math is processed entirely client-side, none of your sensitive financial data ever leaves your device. There are no signups, no email walls, and no tracking.

You simply enter your numbers, and the calculators instantly generate real-time results, visual charts, and full amortization schedules. Every tool includes an "Export to Excel" feature, allowing you to take your data offline for deeper analysis.

The platform covers the most critical financial decisions:
• Mortgage Calculator (with full amortization schedule)
• FIRE Calculator (find your financial independence number)
• Nest Egg Longevity (how long your savings will last)
• Savings Goal (required monthly contributions)
• Debt Snowball vs. Avalanche (side-by-side comparison)
• Personal Loans & Credit Card Debt Payoff
• ETF Compound Interest (projecting growth and fees)

Beyond the calculators, RunMyWealth includes "Retire Abroad"—an automated quiz that ranks countries by how long your savings will last. There is also a plain-English educational blog called Wealth Mechanics that explains the math behind money.

Built solo by an independent developer. Completely free, fully bilingual (English/Spanish), and designed to be the fastest, most private way to model your financial future.
