How compound growth works
This calculator estimates how a starting amount and regular monthly deposits could grow over time. When money remains invested, growth can build on your contributions and on earlier growth. This is called compounding. The longer the money stays invested, the more time compounding has to work.
The return entered in the calculator is a steady rate used to explain the math. Real investments do not grow at the same rate every month or every year. Their value can rise or fall, and they can lose money. A higher assumed return creates a larger estimate, but higher possible returns usually come with more uncertainty and risk.
Key takeaway
Time and regular contributions can matter as much as the amount you start with. Small contributions may become meaningful when they are repeated for many years.
