How Compounding Works
Compound interest is the interest you earn on both your original money and the interest it already gained. It makes your investment grow faster over time because each period builds on the last one. For example, if you earn interest on $1,000, the next time you earn interest on both the $1,000 and the new interest added. The more often it compounds, the faster your balance grows. This is why starting early and staying invested are key to long-term growth.
Different between Compound vs Simple Interest
Simple interest is calculated only on the principal amount, or the initial amount of money you invested. It does not take into account any interest that has already been added to the balance. In contrast, compound interest is calculated on the principal amount and also on any interest that has been added to it over time. This means that with compound interest, you earn interest on your interest, which can lead to much higher returns over the long term.
How to Use This Calculator
To use this calculator, start by entering your initial principal, or the amount you plan to invest. Then set your expected annual interest rate to see how your money grows over time. Choose your time period in years or months, and select how often the interest is added to your balance. Each choice affects your final result, so adjust them to match your real investment plan.
Growth Strategies
For better growth, make regular contributions to your investment. Adding money each month or year increases your balance and helps your interest grow faster. Even small, consistent deposits make a big difference over time. Staying disciplined is key to reaching your financial goals.
Compounding is where your investment truly shines. The more often your interest compounds, the faster your money grows. Daily or monthly compounding adds interest to both your original balance and the interest you have already earned. Time is the most powerful factor in this process. The longer you keep your money invested, the greater your returns become.
