About HandyTallies
Empowering everyday investors, dividend growth accumulators, and FIRE planners with detailed compounding tools that run privately in your browser.
Democratizing Complex Financial Mathematics
Most financial calculators on the web today fall into two frustrating categories: primitive single-equation tools that assume dividends never grow and never compound, or bloated corporate websites designed solely to capture your personal email and sell you expensive wealth management services.
HandyTallies was founded on a simple principle: retail investors deserve high-precision financial modeling tools that load instantaneously, respect user privacy, and account for the real dynamics of long-term dividend reinvestment (DRIP), expanding Yield on Cost, and capital growth.
The HandyTallies Difference
Built from the ground up for speed, transparency, and computational integrity.
100% Client-Side Privacy
Your finances are nobody else's business. All simulation mathematics execute entirely inside your device's browser runtime. We never transmit, store, or sell your net worth, starting amounts, or contribution schedules.
Instant Calculations
Powered by modern static compilation and reactive micro-engines. Changing an input parameter recalculates 60 years of month-by-month compounding instantaneously without page refreshing or server delays.
Dual-Engine Compounding
Unlike static calculators, our models simultaneously simulate dividend yield growth (CAGR) and share price appreciation. This reflects authentic exchange-traded fund behavior over multi-decade horizons.
Spreadsheet Export Ready
Every simulation table can be exported cleanly to standard CSV format. Take your data straight into Microsoft Excel, Google Sheets, or personal financial planning workbooks with custom year selections.
Educational Methodology & Financial Disclaimer
All financial simulation algorithms implemented across HandyTallies are derived from standard actuarial mathematics, quarterly compounding equations, and published historical dividend distribution schedules of benchmark securities (such as the Dow Jones U.S. Dividend 100 Index).
