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.

How much is my 25% tax-free lump sum?
For a £200000 pension pot: 25% = £50000 completely tax-free. The remaining £150000 can be taken as taxable income through drawdown or annuity. For a £400000 pot: £100000 tax-free. For pots over £1073100 the tax-free amount is capped at £268275 — any excess above this is taxable when withdrawn.
Should I take the full 25% lump sum at once?
Taking the full 25% immediately is not always optimal. If you do not need the cash it continues growing tax-free inside your pension. However common reasons to take the lump sum include: paying off your mortgage (eliminating monthly payments reduces retirement income needs) investing in an ISA for tax-free growth outside the pension or covering major expenses like home renovations.
What are small pots rules?
The small pots rule allows you to withdraw up to 3 pension pots of £10000 or less as a lump sum. 25% is tax-free and 75% is taxed at your marginal rate. This applies even if you have already taken benefits from other pensions. It is a useful way to consolidate small pension pots from previous employers and simplify your retirement finances.
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.
