The compound interest formula
How does it work?
Compound interest means you earn interest on your interest. Each period, your capital grows, and the calculation base widens. It's the snowball effect of long-term investing.
Time is your best asset
The earlier you start, the more powerful compounding becomes. Starting at 25 rather than 35, with the same monthly amount, can double your final capital. Time in the market beats timing the market.
Small amounts, big results
Even small monthly contributions have an enormous long-term impact. Adding €100 per month at 5% over 30 years generates over €80,000 in interest alone. Consistency beats size.
