Compound Calculator
Asset growth simulation
How to use
Enter an initial amount, a monthly contribution, an annual return and a duration, and it shows how compounding grows your assets, with a chart and a year-by-year breakdown. You can choose the currency (USD by default; KRW, EUR, GBP and JPY are also available).
Q. What is the difference between simple and compound interest?
A. Simple interest is earned only on the principal, while compound interest is also earned on interest already added, so the gap widens over time.
Q. Can it calculate regular monthly contributions?
A. Yes. It factors in the amount you add every month as well as the initial amount, and you can choose monthly, quarterly or annual compounding.
