I built a free dividend calculator suite (no signup, open-source math)
Every "free" dividend calculator I tried wanted an email, a signup, or a trial. The math behind all of them is public — yield, payout ratio, reinvestment compounding — so I built a dividend payout calculator that's actually free, runs entirely in the browser, and open-sources the engine. What's in it A suite of focused calculators rather than one mega-tool: Dividend yield + payout ratio — the…
For every free dividend calculator the author has tried, they demanded personal information, sign-ups or trials. The math behind these tools is publicly available, so the author decided to create a free, browser-based dividend payout calculator with an open-source engine. The suite includes focused calculators: dividend yield and payout ratio check, DRIP reinvestment calculator, monthly dividend calculator, and ETF calculators for SCHD and QQQI.
A live dividend calendar for QQQI is also provided. The site is a static page with client-side math, and the engine is a tiny open-source TypeScript library called dividend-math. Every formula is a pure function with no I/O, ensuring edge cases are easy to test and understand. Plain number inputs (like 5 for 5%) and percentage inputs, zero-dependency library, and a single source of truth for calculations make the tool robust and reliable.
