Explore how an initial amount and regular contributions can grow.
What is compound interest?
Compound growth means returns can be added to an account balance and then participate in future growth. With regular contributions, the effect can become more noticeable over longer periods.
How this calculator works
Enter an initial amount, a monthly contribution, an assumed annual return and a number of years. The calculation assumes monthly compounding and a constant annual rate for the entire period.
This is a mathematical illustration, not a forecast. Investment returns can rise or fall, and fees, taxes, inflation and withdrawals can materially affect real-world results.
Compound interest FAQ
Does a higher return always mean a better investment?The calculator only shows the mathematical effect of an assumed rate. It does not assess investment risk or suitability.
Are monthly contributions included?Yes. You can change the monthly contribution to model regular additions.
