Frequently Asked Questions (FAQs)
What does this Compound Interest Calculator do?
This tool helps you calculate the future value of your money when invested over time with compound interest. It shows how your investment grows based on initial deposit, monthly contributions, interest rate, and compounding frequency.
What is ‘Compound Frequency’ and why does it matter?
Compound frequency refers to how often the interest is added to your investment (e.g., monthly, quarterly, yearly). The more frequently interest is compounded, the faster your money grows. Monthly compounding generally gives higher returns than yearly.
What happens if I don’t add monthly contributions?
If you leave the monthly contribution as zero, the calculator will only calculate the growth on your initial investment. Adding monthly contributions increases your final balance and interest earned.
Is this calculator useful for SIP (Systematic Investment Plan)?
Yes, this tool works perfectly for SIP calculations. You can enter your monthly SIP amount in the “Monthly Contribution” field and see how much your investment can grow over time.
Can I use this calculator for retirement planning?
Absolutely. You can estimate how much your money will grow over time if you consistently save every month. It’s useful for visualizing retirement savings growth based on current contributions.
Is this tool accurate for real-world investing?
This tool gives an estimate based on consistent interest rates and contributions. Real-world returns may vary due to market fluctuations, fees, taxes, and irregular payments. Use it as a guide, not a guarantee.
