## What is Snowball?

Plan your ETF savings in seconds. Snowball shows how monthly contributions could grow over 10, 20 or 30 years – including compound interest, fund costs, inflation and taxes.

Enter your savings rate, expected return and time horizon. Snowball calculates everything live, with clear charts instead of spreadsheets and instant feedback on every change.

ETF AND INDEX PRESETS
Start with presets for S&P 500, MSCI World, MSCI ACWI, Nasdaq-100, FTSE All-World, STOXX Europe 600, Gold and more. Returns are based on 30-year CAGR assumptions and can be adjusted freely.

COMPARE SCENARIOS
See what changes when your return, savings rate or time horizon changes. Snowball’s scenario matrix helps you understand which lever matters most.

SEE REALISTIC RESULTS
Inflation, capital gains tax, fund costs (TER) and dynamic savings rates are included, so you see a clearer picture of what may actually be left.

FIND YOUR SNOWBALL MOMENT
Discover when compounding starts to matter more than your contributions – and follow milestones on the way from five figures to six figures and beyond.

PRIVATE AND FREE
No ads. No subscription. No tracking. No account. No cloud. Your inputs stay on your device.
