How to Build a Dividend Snowball Over 20 Years
Key takeaways
- The dividend snowball works on the principle of compound interest — reinvested dividends buy new shares, which pay more dividends.
- The key is time and consistency, not the size of the initial investment.
- After 15–20 years, the compounding effect becomes the dominant component of returns.
- Automatic reinvestment via DRIP or an accumulating ETF minimises errors and inaction.
The dividend snowball is a strategy where reinvested dividends buy new shares, those shares generate more dividends, and the cycle accelerates exponentially — like a snowball rolling downhill and growing.
How the snowball works step by step
You start with an initial investment — say CZK 200,000. The portfolio generates dividends, you reinvest those dividends and buy more shares. These new shares pay dividends again, which you reinvest again. Each cycle is larger than the previous one. This is the power of compound interest in practice.
A concrete example over 20 years
- Initial investment: CZK 200,000
- Average dividend yield: 3%
- Average annual dividend growth: 6%
- Total average annual portfolio return (price + dividend): ~9%
- After 20 years: ~CZK 1,120,000 (without additional contributions)
- Annual dividend income in year 20: ~CZK 45,000
If you add CZK 3,000 every month, the results are dramatically higher thanks to DCA (dollar-cost averaging).
Automation is the foundation
The best snowball is the one that rolls by itself. You have two options:
- DRIP (Dividend Reinvestment Plan): the broker automatically reinvests the dividend into the same share
- Accumulating ETF: reinvests the dividend internally — without tax, without decisions, without transaction costs
A comparison of accumulating and distributing ETFs can be found in the article accumulating vs. distributing ETFs.
When to start
Immediately. Every extra year at the beginning has a greater effect than every extra thousand added later. But first choose the right foundation — a broad-market ETF or dividend Aristocrats. You can find your choice of instruments in the ETF navigator.
FAQ
How long does it take before the dividend snowball becomes noticeable?
The first 5–7 years show modest results. Between years 10 and 15 the compounding effect begins to dominate. After 20 years, reinvestment accounts for a larger share of value than the returns themselves. The key is not to give up in the first decade.
How much do I need to start?
It depends on your goal, not on a specific number. Even starting with CZK 50,000 makes sense if you contribute regularly. DCA (regular investing) is more important than the size of the initial investment. Start with what you have.
Is DRIP or an accumulating ETF better?
An accumulating ETF is usually more advantageous for the Czech investor — it reinvests without withholding tax on the dividend and without transaction costs. DRIP for individual stocks may have limitations and tax complications.
Can I speed up the snowball?
Yes — by making regular additional contributions (DCA), choosing companies with a growing dividend, and minimising unnecessary fees. A higher dividend yield does not necessarily speed up the snowball if the share price stagnates — monitor total return.
