Dividend Snowball Calculator
Watch reinvested dividends roll up your share count year after year — the snowball effect that grows your income with no extra money invested.
How the dividend snowball works
Each year, your shares pay a dividend; the calculator reinvests that dividend by buying more shares at that year’s price. Those new shares pay their own dividends the following year, so the share count compounds — the snowball.
Two forces speed it up. The dividend per share grows at the rate you set, so each share pays more over time; and reinvestment keeps adding shares. Share price growth works against the share count (each dividend buys fewer shares as the price rises) but lifts the value of what you hold — which is why the snowball is best measured in shares and income, not just dollars.
For a portfolio view that adds regular contributions and tracks total value, use the dividend reinvestment calculator. To focus on the rising income and yield on cost from a fixed stake, use the dividend growth calculator.
Frequently asked questions
- What is the dividend snowball?
- The dividend snowball is the compounding effect of reinvesting dividends: each payment buys more shares, those shares pay more dividends, and the cycle repeats. Like a snowball rolling downhill, the share count and income grow faster over time — even without adding new money.
- How does the dividend snowball work without new contributions?
- Every dividend you receive is used to buy additional shares. More shares means a bigger dividend next time, which buys even more shares. This calculator shows that pure reinvestment effect: your starting shares grow on their own, and the gap widens as the dividend per share also rises each year.
- How long does it take for the snowball to matter?
- Early on the effect is small — a 4% yield adds roughly 4% more shares in year one. It compounds, so the share count and income curve bend upward most visibly after 10–20 years. Dividend growth on top of reinvestment accelerates it further.
- How is this different from the reinvestment (DRIP) calculator?
- The dividend reinvestment calculator focuses on portfolio value and lets you add monthly contributions. This snowball calculator is share-count-first: it isolates how reinvested dividends alone grow the number of shares you own, which is the heart of the snowball idea.
- Does the share price matter for the snowball?
- Yes. Reinvested dividends buy shares at the prevailing price, so a lower price buys more shares (faster snowball) and a higher price buys fewer. The calculator lets you set a price growth rate to model how rising prices slow share accumulation even as your dividend income keeps climbing.
