How to Use the Compound Interest Calculator
Enter your starting amount, the annual interest rate, the number of years and how often interest compounds. Add an optional monthly contribution if you save regularly, then press Calculate.
How compounding works
Compounding means the interest you earn also earns interest.
More frequent compounding (monthly or daily) grows the balance slightly faster than annual compounding.
Monthly contributions are added each month and then compound too.
The result separates growth from your starting amount and from your contributions.
Tips
Try changing the number of years to see the effect of time. Thanks to compounding, the last years usually add more than the first.
