Money calculators
Compound Interest Calculator
Project how savings may grow with deposits and compound interest.
Explore how a starting balance and recurring monthly contributions could grow over time at a hypothetical annual rate.
Why compounding matters
When interest or investment returns are added to a balance, future growth can occur on both the original money and prior gains. This effect becomes more noticeable over longer periods.
Monthly-contribution assumption
This calculator assumes contributions are added at the end of each monthly period. Real accounts may credit interest or market returns differently.
Not a forecast
The entered annual return is only an assumption. Investment returns can be negative or irregular, and savings rates can change.
Frequently asked questions
Is this investment advice?No. It is a mathematical illustration only.
