Investment Calculator
Project the growth of an investment.
Enter values to see your investment projection.
An investment calculator is a powerful tool designed to help you estimate how your investments might grow over time. By inputting a few key details, you can project the future value of your portfolio and understand the impact of contributions, time, and interest rates.
Key Components of Investment Calculation
This calculator uses a standard compound interest formula to project your investment's growth. The main factors are:
- Starting Amount (Principal): The initial amount of money you invest. A larger principal gives your investment a head start.
- Contributions: Regular amounts of money you add to your investment. Consistent contributions are one of the most effective ways to build wealth over time.
- Rate of Return: The annual percentage you expect to earn on your investment. This is an estimate, as actual returns can vary. Historically, the stock market has returned an average of around 7-10% per year, but this is not a guarantee of future results.
- Time Horizon: The number of years you plan to keep your money invested. The longer your time horizon, the more significant the effect of compounding.
The Power of Compound Interest
The most magical part of investing is compound interest. This is when you earn interest not only on your initial principal but also on the accumulated interest from previous periods. It's often described as "interest on your interest."
For example, if you have $1,000 and earn 10% interest in a year, you'll have $1,100. The next year, you'll earn 10% on $1,100, not just the original $1,000. Over many years, this effect can lead to exponential growth, which is why starting to invest as early as possible is so beneficial.
How to Use the Calculator
- Enter your initial investment amount in the "Starting Amount" field.
- Specify how much you plan to add regularly in the "Monthly Contribution" field.
- Set your investment "Length of Time" in years.
- Provide an "Estimated Interest Rate" you expect to earn annually.
The calculator will then show you a projection of your investment's future value, breaking it down into your total contributions and the total interest earned. The graph provides a powerful visual representation of how your money can grow over your chosen time frame.
