Contributions (€25,000) vs estimated growth (€9,595). Growth is illustrative and not guaranteed.

  • Projected balance uses monthly compounding. Returns are illustrative estimates, not guarantees.

Monthly compounding model

The projection applies your annual rate as a monthly rate and compounds each month. Regular contributions are added at the end of each month in this illustration.

Important limitations

Actual investment results vary with fees, taxes, timing, and market conditions. This tool may help you explore scenarios — it does not predict future performance.

FAQ

Why separate contributions from growth?
Contributions are the money you put in. Estimated growth is what compounding adds on top — useful for comparing saving vs investing scenarios.
