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 two-number sustainability check.
DRIP calculator — year-by-year reinvestment with a results table and chart.
