Investment Compound Interest Calculator

See how much your money can grow using the power of compound interest. This compound interest calculator demonstrates how to put your hard-earned money savings strategy to work. Consistent investing over a long period of time can be an effective strategy to accumulate wealth. Even small deposits to a savings account can add up over time.

How to use investment return calculator:

  1. Enter an initial investment or saving. If you have $2500 to invest right now, include that amount here. If you don't have an initial amount to invest now, you can enter $0.
  2. Choose how many years investment will grow. How long do you plan to keep your money invested? If you're investing in stocks, it's generally a good idea to stay invested for at least five years to weather any volatility post-purchase.
  3. Enter your expected rate of return. For a point of reference, the S&P 500 has a historical average annual total return of about 10%, not accounting for inflation. This doesn't mean you can expect 10% growth every year; you could experience a gain one year and a loss the next. But if you keep your money invested for the long term, the goal is for these gains and losses to average out over time.
  4. Enter your monthly contributions.
