inancial & Analytical Tools
At My Money Toolbox, our goal is to turn complex financial decisions into clear, data-driven insights. Each of our tools is built to help you make smarter choices—whether you’re optimizing taxes, evaluating long-term retirement plans, or assessing the return on sustainable investments. Explore the tools below to gain a deeper understanding of your finances and make confident, informed decisions about your future.
Tax Estimator
Our Tax Estimator goes beyond basic calculators by modeling the full U.S. tax code in detail—including federal, state, and local components—to provide accurate, scenario-based projections. What makes it unique is its ability to estimate the effective marginal tax rate (EMTR) for different income sources, such as wages, dividends, capital gains, Roth conversions, and Social Security benefits. This feature helps you understand not just how much tax you’ll owe, but how each additional dollar of income affects your overall tax burden. Whether you’re planning withdrawals, optimizing investment strategy, or timing deductions, this tool gives you a clear, data-backed picture of your true tax landscape.
Retirement Sustainability Model
The Retirement Sustainability Model empowers you to test the long-term strength of your retirement plan. By simulating investment performance, inflation, and spending patterns, it provides insights into how long your savings could last under various scenarios. With this tool, you can confidently assess your financial independence, identify potential shortfalls, and explore adjustments to sustain your desired lifestyle throughout retirement.
Solar IRR Tool
Our Solar IRR Tool helps you evaluate the financial return on your solar energy investment. It calculates the internal rate of return (IRR) based on installation costs, energy savings, tax credits, and system lifespan—giving you a detailed view of your project’s profitability. Whether you’re a homeowner, developer, or business, this tool supports data-driven decisions that align environmental goals with solid financial performance.
