Why we built this
Most dividend calculators do one thing: multiply your portfolio value by a yield percentage and show you a number. That misses the entire point of dividend investing — the compounding snowball effect that happens when you reinvest dividends year after year, when companies raise their payouts annually, and when your portfolio grows in value over time.
Snowball Dividends was built to show all of those forces working together, visually, in a single chart. The stacked area chart — contributions at the base, capital appreciation in the middle, reinvested dividends on top in gold — lets you see the snowball effect in action rather than just reading a final number.
What makes it different
- Four compounding inputs: DRIP reinvestment, dividend growth rate, share-price appreciation, and ongoing contributions — not just yield × balance.
- After-tax modeling: Enter your dividend tax rate and see real net income, not just gross figures.
- Income-goal reverse calculator: The most common question investors have is "how much do I need?" — not "what will I have?" We answer both.
- Yield on cost: See how your original investment's effective yield grows as the dividend compounds over time.
- Fast and private: Everything runs in your browser. No data is sent to any server. No account required.
Who it's for
Snowball Dividends is built for individual investors who use a dividend growth strategy — buying quality dividend-paying stocks and reinvesting the income to build a growing passive income stream over time. It's equally useful for someone just starting out who wants to understand the math, and for experienced investors stress-testing assumptions.
A note on accuracy
This calculator uses simplified annual compounding and constant-rate assumptions. Real markets don't behave that way — yields fluctuate, companies cut dividends, prices fall. The tool is designed to illustrate the principle of compounding, not to predict your actual returns. Always consult a qualified financial advisor before making investment decisions.
