Preguntas frecuentes
What is compound interest?+
Compound interest is interest earned on both your original balance and the interest already added. Over time this compounding effect accelerates growth.
How do monthly contributions change the result?+
Each contribution starts earning interest from the moment it is added, so regular contributions can have a large impact on the final balance — especially over many years.
