Frequently Asked Questions
What is compound interest?▼
Compound interest is interest earned on both the principal amount and the accumulated interest from previous periods. This is often called "interest on interest" and is one of the most powerful concepts in investing and finance.
How often is interest compounded?▼
Interest can be compounded at various intervals: annually (once per year), semi-annually (twice per year), quarterly (four times per year), monthly (12 times per year), daily (365 times per year), or continuously. The more frequently interest is compounded, the more you earn.
What is the difference between simple and compound interest?▼
Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus accumulated interest. Compound interest grows much faster, especially over longer periods.
How long does it take money to double with compound interest?▼
You can use the Rule of 72: divide 72 by your annual interest rate to get approximately how many years it takes for your money to double. For example, at 6% interest, it would take about 12 years (72÷6=12).
Can I use this calculator for real investments?▼
Yes, this calculator provides accurate estimates for any investment with a fixed interest rate. However, real-world investments may have variable rates or fees, so always consult with a financial advisor for specific investment decisions.
What if I want to add regular deposits?▼
This calculator shows the growth from your initial principal. For regular deposits (like monthly savings), the calculation would be more complex. Use this as a starting point and consult a financial advisor for more sophisticated scenarios.
