Understanding Your Investment Returns
This calculator projects your returns using compound interest, where your earnings generate their own earnings over time. The power of compounding means that even small regular investments can grow into substantial wealth over long periods. For example, investing just Rs 5,000 per month at 12% expected returns for 25 years can grow to over Rs 1 crore — of which only Rs 15 lakh is your own money and Rs 85 lakh is compounding returns. The key factors that determine your final corpus are: the amount invested, the rate of return, the duration of investment, and the frequency of compounding.
Important Considerations
Past returns do not guarantee future performance, especially for market-linked instruments like mutual funds and equities. The returns shown are estimates based on the rate you enter. Equity investments carry market risk but have historically delivered 12-15% CAGR over 15+ year periods in India. Fixed income options like PPF (7.1%) and FD (6-7.5%) offer lower but more predictable returns. Diversifying across asset classes — equity, debt, gold, and real estate — reduces overall portfolio risk while optimizing returns for your risk tolerance.

Roth IRA vs Traditional IRA which is better?
Roth IRA is better if you expect to be in a higher tax bracket in retirement or if you are currently in a low bracket. Traditional IRA is better if you need the current tax deduction and expect lower retirement income. If unsure split contributions between both. Roth has the added advantage of no required minimum distributions and penalty-free withdrawal of contributions at any time.
Can I contribute to both 401k and Roth IRA?
Yes you can contribute to both a 401k and a Roth IRA simultaneously as they have separate contribution limits. The optimal strategy is: first contribute enough to 401k to get your full employer match then max out Roth IRA ($7000) then put remaining savings back into 401k up to its limit ($23500). This gives you both tax-deferred and tax-free retirement income.
What is compound interest and why does it matter?
Compound interest means you earn interest on your interest, not just your principal. Over long periods, this creates exponential growth — even small regular investments can grow into substantial wealth over 15-25 years.
Should I invest regularly or as a lump sum?
Regular investing (dollar-cost averaging) smooths out market volatility by buying at various price points. Lump sum investing works better if markets are undervalued. For most people, regular monthly investing is simpler and more disciplined.
How much should I invest monthly to reach my goal?
The amount depends on your target, timeline, and expected returns. Use this calculator to model different scenarios. The key factors are starting early, investing consistently, and reinvesting returns.
Are investment returns taxable?
Tax treatment varies by investment type and country. Capital gains, dividends, and interest income may be taxed differently. Consult a tax professional for advice specific to your situation and jurisdiction.
