Frequently Asked Questions
Compound interest is interest earned on both the initial principal and previously earned interest. It's "interest on interest" that accelerates wealth growth over time.
Use the formula: FV = PV × (1 + r)^n, where FV is future value, PV is present value (principal), r is interest rate, and n is number of years.
Simple interest is calculated only on the principal amount, while compound interest is calculated on principal plus accumulated interest. Compound interest grows much faster over time.
More frequent compounding (daily, monthly, quarterly) results in slightly higher returns than annual compounding, but the difference decreases as compounding frequency increases.
Time and interest rate have the biggest impact. Even small increases in interest rate or investment timeline can dramatically increase final amounts due to exponential growth.
This calculator assumes constant interest rates, which is ideal for fixed deposits or bonds. Real investments have variable returns, so use this as a baseline estimate.
Start early, invest regularly, seek higher interest rates, avoid withdrawing funds, and consider tax-advantaged accounts like 401(k)s or IRAs for long-term growth.
Historical stock market returns average 7-10% annually, bonds around 3-5%, and high-yield savings accounts 1-4%. Higher returns come with higher risk.
Yes! Inflation reduces purchasing power over time. Subtract the average inflation rate (around 2-3%) from your interest rate to get the real growth rate.
Absolutely! This calculator is perfect for estimating retirement fund growth. Consider using conservative interest rates (6-7%) and factor in regular contributions for more accurate planning.
