How this works: Compound interest means you earn returns on both your original investment and the interest already accumulated. The more frequently interest compounds, and the longer you stay invested, the more powerful the effect — often called the "eighth wonder of the world." This calculator shows the impact of regular monthly contributions alongside compounding.
