Frequently Asked Questions
Higher compounding frequency generally increases returns. However, the difference becomes less significant with higher frequencies.
Use conservative estimates: 6-8% for fixed deposits, 8-10% for balanced funds, 10-12% for equity investments. Always consider inflation impact and use slightly lower rates for safety margin.
Starting early is extremely powerful. Due to exponential growth, starting 10 years earlier can result in significantly higher wealth even with the same total investment amount.
Compound interest calculator is ideal for fixed-return investments like FDs, bonds, and PPF. For market-linked investments like mutual funds, use it for projection purposes with realistic return assumptions.
Calculate your real return by subtracting inflation rate from nominal return. For example, if your investment gives 10% and inflation is 6%, your real return is approximately 4%.
While the mathematical principle is similar, use dedicated EMI calculators for loans as they account for regular payments and different calculation methods specific to loan structures.
